+Fixed link Device Tree binding
+------------------------------
+
+Some Ethernet MACs have a "fixed link", and are not connected to a
+normal MDIO-managed PHY device. For those situations, a Device Tree
+binding allows to describe a "fixed link".
+
+Such a fixed link situation is described by creating a 'fixed-link'
+sub-node of the Ethernet MAC device node, with the following
+properties:
+
+* 'speed' (integer, mandatory), to indicate the link speed. Accepted
+ values are 10, 100 and 1000
+* 'full-duplex' (boolean, optional), to indicate that full duplex is
+ used. When absent, half duplex is assumed.
+* 'pause' (boolean, optional), to indicate that pause should be
+ enabled.
+* 'asym-pause' (boolean, optional), to indicate that asym_pause should
+ be enabled.
+
+Old, deprecated 'fixed-link' binding:
+
+* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
+ form <a b c d e> with the following accepted values:
+ - a: emulated PHY ID, choose any but but unique to the all specified
+ fixed-links, from 0 to 31
+ - b: duplex configuration: 0 for half duplex, 1 for full duplex
+ - c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
+ - d: pause configuration: 0 for no pause, 1 for pause
+ - e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
+ asymmetric pause
+
+Example:
+
+ethernet@0 {
+ ...
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ ...
+};

+ cdc_mbim - Driver for CDC MBIM Mobile Broadband modems
+ ========================================================
+
+The cdc_mbim driver supports USB devices conforming to the "Universal
+Serial Bus Communications Class Subclass Specification for Mobile
+Broadband Interface Model" [1], which is a further development of
+"Universal Serial Bus Communications Class Subclass Specifications for
+Network Control Model Devices" [2] optimized for Mobile Broadband
+devices, aka "3G/LTE modems".
+
+
+Command Line Parameters
+=======================
+
+The cdc_mbim driver has no parameters of its own. But the probing
+behaviour for NCM 1.0 backwards compatible MBIM functions (an
+"NCM/MBIM function" as defined in section 3.2 of [1]) is affected
+by a cdc_ncm driver parameter:
+
+prefer_mbim
+-----------
+Type: Boolean
+Valid Range: N/Y (0-1)
+Default Value: Y (MBIM is preferred)
+
+This parameter sets the system policy for NCM/MBIM functions. Such
+functions will be handled by either the cdc_ncm driver or the cdc_mbim
+driver depending on the prefer_mbim setting. Setting prefer_mbim=N
+makes the cdc_mbim driver ignore these functions and lets the cdc_ncm
+driver handle them instead.
+
+The parameter is writable, and can be changed at any time. A manual
+unbind/bind is required to make the change effective for NCM/MBIM
+functions bound to the "wrong" driver
+
+
+Basic usage
+===========
+
+MBIM functions are inactive when unmanaged. The cdc_mbim driver only
+provides an userspace interface to the MBIM control channel, and will
+not participate in the management of the function. This implies that a
+userspace MBIM management application always is required to enable a
+MBIM function.
+
+Such userspace applications includes, but are not limited to:
+ - mbimcli (included with the libmbim [3] library), and
+ - ModemManager [4]
+
+Establishing a MBIM IP session reequires at least these actions by the
+management application:
+ - open the control channel
+ - configure network connection settings
+ - connect to network
+ - configure IP interface
+
+Management application development
+----------------------------------
+The driver <-> userspace interfaces are described below. The MBIM
+control channel protocol is described in [1].
+
+
+MBIM control channel userspace ABI
+==================================
+
+/dev/cdc-wdmX character device
+------------------------------
+The driver creates a two-way pipe to the MBIM function control channel
+using the cdc-wdm driver as a subdriver. The userspace end of the
+control channel pipe is a /dev/cdc-wdmX character device.
+
+The cdc_mbim driver does not process or police messages on the control
+channel. The channel is fully delegated to the userspace management
+application. It is therefore up to this application to ensure that it
+complies with all the control channel requirements in [1].
+
+The cdc-wdmX device is created as a child of the MBIM control
+interface USB device. The character device associated with a specific
+MBIM function can be looked up using sysfs. For example:
+
+ bjorn@nemi:~$ ls /sys/bus/usb/drivers/cdc_mbim/2-4:2.12/usbmisc
+ cdc-wdm0
+
+ bjorn@nemi:~$ grep . /sys/bus/usb/drivers/cdc_mbim/2-4:2.12/usbmisc/cdc-wdm0/dev
+ 180:0
+
+
+USB configuration descriptors
+-----------------------------
+The wMaxControlMessage field of the CDC MBIM functional descriptor
+limits the maximum control message size. The managament application is
+responsible for negotiating a control message size complying with the
+requirements in section 9.3.1 of [1], taking this descriptor field
+into consideration.
+
+The userspace application can access the CDC MBIM functional
+descriptor of a MBIM function using either of the two USB
+configuration descriptor kernel interfaces described in [6] or [7].
+
+See also the ioctl documentation below.
+
+
+Fragmentation
+-------------
+The userspace application is responsible for all control message
+fragmentation and defragmentaion, as described in section 9.5 of [1].
+
+
+/dev/cdc-wdmX write()
+---------------------
+The MBIM control messages from the management application *must not*
+exceed the negotiated control message size.
+
+
+/dev/cdc-wdmX read()
+--------------------
+The management application *must* accept control messages of up the
+negotiated control message size.
+
+
+/dev/cdc-wdmX ioctl()
+--------------------
+IOCTL_WDM_MAX_COMMAND: Get Maximum Command Size
+This ioctl returns the wMaxControlMessage field of the CDC MBIM
+functional descriptor for MBIM devices. This is intended as a
+convenience, eliminating the need to parse the USB descriptors from
+userspace.

+Custom device services
+----------------------
+The MBIM specification allows vendors to freely define additional
+services. This is fully supported by the cdc_mbim driver.
+
+Support for new MBIM services, including vendor specified services, is
+implemented entirely in userspace, like the rest of the MBIM control
+protocol
+
+New services should be registered in the MBIM Registry [5].
+
+
+
+MBIM data channel userspace ABI
+===============================
+
+wwanY network device
+--------------------
+The cdc_mbim driver represents the MBIM data channel as a single
+network device of the "wwan" type. This network device is initially
+mapped to MBIM IP session 0.
+
+
+Multiplexed IP sessions (IPS)
+-----------------------------
+MBIM allows multiplexing up to 256 IP sessions over a single USB data
+channel. The cdc_mbim driver models such IP sessions as 802.1q VLAN
+subdevices of the master wwanY device, mapping MBIM IP session Z to
+VLAN ID Z for all values of Z greater than 0.
+
+The device maximum Z is given in the MBIM_DEVICE_CAPS_INFO structure
+described in section 10.5.1 of [1].
+
+The userspace management application is responsible for adding new
+VLAN links prior to establishing MBIM IP sessions where the SessionId
+is greater than 0. These links can be added by using the normal VLAN
+kernel interfaces, either ioctl or netlink.
+
+For example, adding a link for a MBIM IP session with SessionId 3:
+
+ ip link add link wwan0 name wwan0.3 type vlan id 3
+
+The driver will automatically map the "wwan0.3" network device to MBIM
+IP session 3.
+
+
+Device Service Streams (DSS)
+----------------------------
+MBIM also allows up to 256 non-IP data streams to be multiplexed over
+the same shared USB data channel. The cdc_mbim driver models these
+sessions as another set of 802.1q VLAN subdevices of the master wwanY
+device, mapping MBIM DSS session A to VLAN ID (256 + A) for all values
+of A.
+
+The device maximum A is given in the MBIM_DEVICE_SERVICES_INFO
+structure described in section 10.5.29 of [1].
+
+The DSS VLAN subdevices are used as a practical interface between the
+shared MBIM data channel and a MBIM DSS aware userspace application.
+It is not intended to be presented as-is to an end user. The
+assumption is that an userspace application initiating a DSS session
+also takes care of the necessary framing of the DSS data, presenting
+the stream to the end user in an appropriate way for the stream type.
+
+The network device ABI requires a dummy ethernet header for every DSS
+data frame being transported. The contents of this header is
+arbitrary, with the following exceptions:
+ - TX frames using an IP protocol (0x0800 or 0x86dd) will be dropped
+ - RX frames will have the protocol field set to ETH_P_802_3 (but will
+ not be properly formatted 802.3 frames)
+ - RX frames will have the destination address set to the hardware
+ address of the master device
+
+The DSS supporting userspace management application is responsible for
+adding the dummy ethernet header on TX and stripping it on RX.
+
+This is a simple example using tools commonly available, exporting
+DssSessionId 5 as a pty character device pointed to by a /dev/nmea
+symlink:
+
+ ip link add link wwan0 name wwan0.dss5 type vlan id 261
+ ip link set dev wwan0.dss5 up
+ socat INTERFACE:wwan0.dss5,type=2 PTY:,echo=0,link=/dev/nmea
+
+This is only an example, most suitable for testing out a DSS
+service. Userspace applications supporting specific MBIM DSS services
+are expected to use the tools and programming interfaces required by
+that service.
+
+Note that adding VLAN links for DSS sessions is entirely optional. A
+management application may instead choose to bind a packet socket
+directly to the master network device, using the received VLAN tags to
+map frames to the correct DSS session and adding 18 byte VLAN ethernet
+headers with the appropriate tag on TX. In this case using a socket
+filter is recommended, matching only the DSS VLAN subset. This avoid
+unnecessary copying of unrelated IP session data to userspace. For
+example:
+
+ static struct sock_filter dssfilter[] = {
+ /* use special negative offsets to get VLAN tag */
+ BPF_STMT(BPF_LD|BPF_B|BPF_ABS, SKF_AD_OFF + SKF_AD_VLAN_TAG_PRESENT),
+ BPF_JUMP(BPF_JMP|BPF_JEQ|BPF_K, 1, 0, 6), /* true */
+
+ /* verify DSS VLAN range */
+ BPF_STMT(BPF_LD|BPF_H|BPF_ABS, SKF_AD_OFF + SKF_AD_VLAN_TAG),
+ BPF_JUMP(BPF_JMP|BPF_JGE|BPF_K, 256, 0, 4), /* 256 is first DSS VLAN */
+ BPF_JUMP(BPF_JMP|BPF_JGE|BPF_K, 512, 3, 0), /* 511 is last DSS VLAN */
+
+ /* verify ethertype */
+ BPF_STMT(BPF_LD|BPF_H|BPF_ABS, 2 * ETH_ALEN),
+ BPF_JUMP(BPF_JMP|BPF_JEQ|BPF_K, ETH_P_802_3, 0, 1),
+
+ BPF_STMT(BPF_RET|BPF_K, (u_int)-1), /* accept */
+ BPF_STMT(BPF_RET|BPF_K, 0), /* ignore */
+ };
+
+
+
+Tagged IP session 0 VLAN
+------------------------
+As described above, MBIM IP session 0 is treated as special by the
+driver. It is initially mapped to untagged frames on the wwanY
+network device.
+
+This mapping implies a few restrictions on multiplexed IPS and DSS
+sessions, which may not always be practical:
+ - no IPS or DSS session can use a frame size greater than the MTU on
+ IP session 0
+ - no IPS or DSS session can be in the up state unless the network
+ device representing IP session 0 also is up
+
+These problems can be avoided by optionally making the driver map IP
+session 0 to a VLAN subdevice, similar to all other IP sessions. This
+behaviour is triggered by adding a VLAN link for the magic VLAN ID
+4094. The driver will then immediately start mapping MBIM IP session
+0 to this VLAN, and will drop untagged frames on the master wwanY
+device.
+
+Tip: It might be less confusing to the end user to name this VLAN
+subdevice after the MBIM SessionID instead of the VLAN ID. For
+example:
+
+ ip link add link wwan0 name wwan0.0 type vlan id 4094
+
+
+VLAN mapping
+------------
+
+Summarizing the cdc_mbim driver mapping described above, we have this
+relationship between VLAN tags on the wwanY network device and MBIM
+sessions on the shared USB data channel:
+
+ VLAN ID MBIM type MBIM SessionID Notes
+ ---------------------------------------------------------
+ untagged IPS 0 a)
+ 1 - 255 IPS 1 - 255 <VLANID>
+ 256 - 511 DSS 0 - 255 <VLANID - 256>
+ 512 - 4093 b)
+ 4094 IPS 0 c)
+
+ a) if no VLAN ID 4094 link exists, else dropped
+ b) unsupported VLAN range, unconditionally dropped
+ c) if a VLAN ID 4094 link exists, else dropped
+

- Introduces bpf_call insn and register passing convention for zero overhead
calls from/to other kernel functions:
- After a kernel function call, R1 - R5 are reset to unreadable and R0 has a
- return type of the function. Since R6 - R9 are callee saved, their state is

+ Before an in-kernel function call, the internal BPF program needs to
+ place function arguments into R1 to R5 registers to satisfy calling
+ convention, then the interpreter will take them from registers and pass
+ to in-kernel function. If R1 - R5 registers are mapped to CPU registers
+ that are used for argument passing on given architecture, the JIT compiler
+ doesn't need to emit extra moves. Function arguments will be in the correct
+ registers and BPF_CALL instruction will be JITed as single 'call' HW
+ instruction. This calling convention was picked to cover common call
+ situations without performance penalty.
+
+ After an in-kernel function call, R1 - R5 are reset to unreadable and R0 has
+ a return value of the function. Since R6 - R9 are callee saved, their state

+
+ For example, consider three C functions:
+
+ u64 f1() { return (*_f2)(1); }
+ u64 f2(u64 a) { return f3(a + 1, a); }
+ u64 f3(u64 a, u64 b) { return a - b; }
+
+ GCC can compile f1, f3 into x86_64:
+
+ f1:
+ movl $1, %edi
+ movq _f2(%rip), %rax
+ jmp *%rax
+ f3:
+ movq %rdi, %rax
+ subq %rsi, %rax
+ ret
+
+ Function f2 in BPF may look like:
+
+ f2:
+ bpf_mov R2, R1
+ bpf_add R1, 1
+ bpf_call f3
+ bpf_exit
+
+ If f2 is JITed and the pointer stored to '_f2'. The calls f1 -> f2 -> f3 and
+ returns will be seamless. Without JIT, __sk_run_filter() interpreter needs to
+ be used to call into f2.
+
+ For practical reasons all BPF programs have only one argument 'ctx' which is
+ already placed into R1 (e.g. on __sk_run_filter() startup) and the programs
+ can call kernel functions with up to 5 arguments. Calls with 6 or more arguments
+ are currently not supported, but these restrictions can be lifted if necessary
+ in the future.
+
+ On 64-bit architectures all register map to HW registers one to one. For
+ example, x86_64 JIT compiler can map them as ...
+
+ R0 - rax
+ R1 - rdi
+ R2 - rsi
+ R3 - rdx
+ R4 - rcx
+ R5 - r8
+ R6 - rbx
+ R7 - r13
+ R8 - r14
+ R9 - r15
+ R10 - rbp
+
+ ... since x86_64 ABI mandates rdi, rsi, rdx, rcx, r8, r9 for argument passing
+ and rbx, r12 - r15 are callee saved.
+
+ Then the following internal BPF pseudo-program:
+
+ bpf_mov R6, R1 /* save ctx */
+ bpf_mov R2, 2
+ bpf_mov R3, 3
+ bpf_mov R4, 4
+ bpf_mov R5, 5

+ bpf_mov R7, R0 /* save foo() return value */
+ bpf_mov R1, R6 /* restore ctx for next call */
+ bpf_mov R2, 6
+ bpf_mov R3, 7
+ bpf_mov R4, 8
+ bpf_mov R5, 9
+ bpf_call bar
+ bpf_add R0, R7
+ bpf_exit
+
+ After JIT to x86_64 may look like:
+
+ push %rbp
+ mov %rsp,%rbp
+ sub $0x228,%rsp
+ mov %rbx,-0x228(%rbp)
+ mov %r13,-0x220(%rbp)
+ mov %rdi,%rbx
+ mov $0x2,%esi
+ mov $0x3,%edx
+ mov $0x4,%ecx
+ mov $0x5,%r8d

+ mov %rax,%r13
+ mov %rbx,%rdi
+ mov $0x2,%esi
+ mov $0x3,%edx
+ mov $0x4,%ecx
+ mov $0x5,%r8d
+ callq bar
+ add %r13,%rax
+ mov -0x228(%rbp),%rbx
+ mov -0x220(%rbp),%r13
+ leaveq
+ retq
+
+ Which is in this example equivalent in C to:
+
+ u64 bpf_filter(u64 ctx)
+ {
+ return foo(ctx, 2, 3, 4, 5) + bar(ctx, 6, 7, 8, 9);
+ }
+
+ In-kernel functions foo() and bar() with prototype: u64 (*)(u64 arg1, u64
+ arg2, u64 arg3, u64 arg4, u64 arg5); will receive arguments in proper
+ registers and place their return value into '%rax' which is R0 in BPF.
+ Prologue and epilogue are emitted by JIT and are implicit in the
+ interpreter. R0-R5 are scratch registers, so BPF program needs to preserve
+ them across the calls as defined by calling convention.
+

+
+ bpf_mov R1, 1
+ bpf_call foo
+ bpf_mov R0, R1
+ bpf_exit

-The Digi Intl. epca driver.
-----------------------------
-The Digi Intl. epca driver for Linux supports the following boards:
-
-Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve
-Digi EISA/Xem, PCI/Xem, PCI/Xr
-
-Limitations:
-------------
-Currently the driver only autoprobes for supported PCI boards.
-
-The Linux MAKEDEV command does not support generating the Digiboard
-Devices. Users executing digiConfig to setup EISA and PC series cards
-will have their device nodes automatically constructed (cud?? for ~CLOCAL,
-and ttyD?? for CLOCAL). Users wishing to boot their board from the LILO
-prompt, or those users booting PCI cards may use buildDIGI to construct
-the necessary nodes.
-
-Notes:
-------
-This driver may be configured via LILO. For users who have already configured
-their driver using digiConfig, configuring from LILO will override previous
-settings. Multiple boards may be configured by issuing multiple LILO command
-lines. For examples see the bottom of this document.
-
-Device names start at 0 and continue up. Beware of this as previous Digi
-drivers started device names with 1.
-
-PCI boards are auto-detected and configured by the driver. PCI boards will
-be allocated device numbers (internally) beginning with the lowest PCI slot
-first. In other words a PCI card in slot 3 will always have higher device
-nodes than a PCI card in slot 1.
-
-LILO config examples:
----------------------
-Using LILO's APPEND command, a string of comma separated identifiers or
-integers can be used to configure supported boards. The six values in order
-are:
-
- Enable/Disable this card or Override,
- Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2),
- EISA/Xem (3), PC/64Xe (4), PC/Xi (5),
- Enable/Disable alternate pin arrangement,
- Number of ports on this card,
- I/O Port where card is configured (in HEX if using string identifiers),
- Base of memory window (in HEX if using string identifiers),
-
-NOTE : PCI boards are auto-detected and configured. Do not attempt to
-configure PCI boards with the LILO append command. If you wish to override
-previous configuration data (As set by digiConfig), but you do not wish to
-configure any specific card (Example if there are PCI cards in the system)
-the following override command will accomplish this:
--> append="digi=2"
-
-Samples:
- append="digiepca=E,PC/Xe,D,16,200,D0000"
- or
- append="digi=1,0,0,16,512,851968"
-
-Supporting Tools:
------------------
-Supporting tools include digiDload, digiConfig, buildPCI, and ditty. See
-drivers/char/README.epca for more details. Note,
-this driver REQUIRES that digiDload be executed prior to it being used.
-Failure to do this will result in an ENODEV error.

- any of its options, excluding port & irq settings.
-
-3) There are some misc. defines at the beginning of riscom8.c, please read the
- comments and try to change some of them in case of problems.
-

-Intro
-=====
-
-
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources? And the manual of one of the boards in your computer?
-
-
-Addresses and interrupts
-========================
-
-Address dip switch settings:
-The dip switch sets bits 2-9 of the IO address.
-
- 9 8 7 6 5 4 3 2
- +-----------------+
- 0 | X X X X X X X |
- | | = IoBase = 0x100
- 1 | X |
- +-----------------+ ------ RS232 connectors ---->
-
- | | |
- edge connector
- | | |
- V V V
-
-Base address 0x100 caused a conflict in one of my computers once. I
-haven't the foggiest why. My Specialix card is now at 0x180. My
-other computer runs just fine with the Specialix card at 0x100....
-The card occupies 4 addresses, but actually only two are really used.
-
-The PCI version doesn't have any dip switches. The BIOS assigns
-an IO address.
-
-The driver now still autoprobes at 0x100, 0x180, 0x250 and 0x260. If
-that causes trouble for you, please report that. I'll remove
-autoprobing then.
-
-The driver will tell the card what IRQ to use, so you don't have to
-change any jumpers to change the IRQ. Just use a command line
-argument (irq=xx) to the insmod program to set the interrupt.
-
-The BIOS assigns the IRQ on the PCI version. You have no say in what
-IRQ to use in that case.
-
-If your specialix cards are not at the default locations, you can use
-the kernel command line argument "specialix=io0,irq0,io1,irq1...".
-Here "io0" is the io address for the first card, and "irq0" is the
-irq line that the first card should use. And so on.
-
-Examples.
-
-You use the driver as a module and have three cards at 0x100, 0x250
-and 0x180. And some way or another you want them detected in that
-order. Moreover irq 12 is taken (e.g. by your PS/2 mouse).
-
- insmod specialix.o iobase=0x100,0x250,0x180 irq=9,11,15
-
-The same three cards, but now in the kernel would require you to
-add
-
- specialix=0x100,9,0x250,11,0x180,15
-
-to the command line. This would become
-
- append="specialix=0x100,9,0x250,11,0x180,15"
-
-in your /etc/lilo.conf file if you use lilo.
-
-The Specialix driver is slightly odd: It allows you to have the second
-or third card detected without having a first card. This has
-advantages and disadvantages. A slot that isn't filled by an ISA card,
-might be filled if a PCI card is detected. Thus if you have an ISA
-card at 0x250 and a PCI card, you would get:
-
-sx0: specialix IO8+ Board at 0x100 not found.
-sx1: specialix IO8+ Board at 0x180 not found.
-sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev. B.
-sx3: specialix IO8+ Board at 0x260 not found.
-sx0: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-This would happen if you don't give any probe hints to the driver.
-If you would specify:
-
- specialix=0x250,11
-
-you'd get the following messages:
-
-sx0: specialix IO8+ board detected at 0x250, IRQ 11, CD1865 Rev. B.
-sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-ISA probing is aborted after the IO address you gave is exhausted, and
-the PCI card is now detected as the second card. The ISA card is now
-also forced to IRQ11....
-
-
-Baud rates
-==========
-
-The rev 1.2 and below boards use a CL-CD1864. These chips can only
-do 64kbit. The rev 1.3 and newer boards use a CL-CD1865. These chips
-are officially capable of 115k2.
-
-The Specialix card uses a 25MHz crystal (in times two mode, which in
-fact is a divided by two mode). This is not enough to reach the rated
-115k2 on all ports at the same time. With this clock rate you can only
-do 37% of this rate. This means that at 115k2 on all ports you are
-going to lose characters (The chip cannot handle that many incoming
-bits at this clock rate.) (Yes, you read that correctly: there is a
-limit to the number of -=bits=- per second that the chip can handle.)
-
-If you near the "limit" you will first start to see a graceful
-degradation in that the chip cannot keep the transmitter busy at all
-times. However with a central clock this slow, you can also get it to
-miss incoming characters. The driver will print a warning message when
-you are outside the official specs. The messages usually show up in
-the file /var/log/messages .
-
-The specialix card cannot reliably do 115k2. If you use it, you have
-to do "extensive testing" (*) to verify if it actually works.
-
-When "mgetty" communicates with my modem at 115k2 it reports:
-got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a]
- ^^^^ ^^^^ ^^^^
-
-The three characters that have the "^^^" under them have suffered a
-bit error in the highest bit. In conclusion: I've tested it, and found
-that it simply DOESN'T work for me. I also suspect that this is also
-caused by the baud rate being just a little bit out of tune.
-
-I upgraded the crystal to 66Mhz on one of my Specialix cards. Works
-great! Contact me for details. (Voids warranty, requires a steady hand
-and more such restrictions....)

-
-
-Hardware handshaking issues.
-============================
-
-The driver can be told to operate in two different ways. The default
-behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when
-hardware handshaking is off. It behaves as the RTS hardware
-handshaking signal when hardware handshaking is selected.
-
-When you use this, you have to use the appropriate cable. The
-cable will either be compatible with hardware handshaking or with
-software handshaking. So switching on the fly is not really an
-option.
-
-I actually prefer to use the "specialix.sx_rtscts=1" option.
-This makes the DTR/RTS pin always an RTS pin, and ioctls to
-change DTR are always ignored. I have a cable that is configured
-for this.
-
-
-Ports and devices
-=================
-
-Port 0 is the one furthest from the card-edge connector.
-
-Devices:
-
-You should make the devices as follows:
-
-bash
-cd /dev
-for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 \
- 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
-do
- echo -n "$i "
- mknod /dev/ttyW$i c 75 $i
- mknod /dev/cuw$i c 76 $i
-done
-echo ""
-
-If your system doesn't come with these devices preinstalled, bug your
-linux-vendor about this. They have had ample time to get this
-implemented by now.
-
-You cannot have more than 4 boards in one computer. The card only
-supports 4 different interrupts. If you really want this, contact me
-about this and I'll give you a few tips (requires soldering iron)....
-
-If you have enough PCI slots, you can probably use more than 4 PCI
-versions of the card though....
-
-The PCI version of the card cannot adhere to the mechanical part of
-the PCI spec because the 8 serial connectors are simply too large. If
-it doesn't fit in your computer, bring back the card.
-
-
-------------------------------------------------------------------------
-
-
- Fixed bugs and restrictions:
- - During initialization, interrupts are blindly turned on.
- Having a shadow variable would cause an extra memory
- access on every IO instruction.
- - The interrupt (on the card) should be disabled when we
- don't allocate the Linux end of the interrupt. This allows
- a different driver/card to use it while all ports are not in
- use..... (a la standard serial port)
- == An extra _off variant of the sx_in and sx_out macros are
- now available. They don't set the interrupt enable bit.
- These are used during initialization. Normal operation uses
- the old variant which enables the interrupt line.
- - RTS/DTR issue needs to be implemented according to
- specialix' spec.
- I kind of like the "determinism" of the current
- implementation. Compile time flag?
- == Ok. Compile time flag! Default is how Specialix likes it.
- == Now a config time flag! Gets saved in your config file. Neat!
- - Can you set the IO address from the lilo command line?
- If you need this, bug me about it, I'll make it.
- == Hah! No bugging needed. Fixed! :-)
- - Cirrus logic hasn't gotten back to me yet why the CD1865 can
- and the CD1864 can't do 115k2. I suspect that this is
- because the CD1864 is not rated for 33MHz operation.
- Therefore the CD1864 versions of the card can't do 115k2 on
- all ports just like the CD1865 versions. The driver does
- not block 115k2 on CD1864 cards.
- == I called the Cirrus Logic representative here in Holland.
- The CD1864 databook is identical to the CD1865 databook,
- except for an extra warning at the end. Similar Bit errors
- have been observed in testing at 115k2 on both an 1865 and
- a 1864 chip. I see no reason why I would prohibit 115k2 on
- 1864 chips and not do it on 1865 chips. Actually there is
- reason to prohibit it on BOTH chips. I print a warning.
- If you use 115k2, you're on your own.
- - A spiky CD may send spurious HUPs. Also in CLOCAL???
- -- A fix for this turned out to be counter productive.
- Different fix? Current behaviour is acceptable?
- -- Maybe the current implementation is correct. If anybody
- gets bitten by this, please report, and it will get fixed.
-
- -- Testing revealed that when in CLOCAL, the problem doesn't
- occur. As warned for in the CD1865 manual, the chip may
- send modem intr's on a spike. We could filter those out,
- but that would be a cludge anyway (You'd still risk getting
- a spurious HUP when two spikes occur.).....
-
-
-
- Bugs & restrictions:
- - This is a difficult card to autoprobe.
- You have to WRITE to the address register to even
- read-probe a CD186x register. Disable autodetection?
- -- Specialix: any suggestions?

-Introduction
-============
-
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources? And the manual of one of the boards in your computer?
-
-
-Theory of operation
-===================
-
-An important thing to know is that the driver itself doesn't have the
-firmware for the card. This means that you need the separate package
-"sx_firmware". For now you can get the source at
-
- ftp://ftp.bitwizard.nl/specialix/sx_firmware_<version>.tgz
-
-The firmware load needs a "misc" device, so you'll need to enable the
-"Support for user misc device modules" in your kernel configuration.
-The misc device needs to be called "/dev/specialix_sxctl". It needs
-misc major 10, and minor number 167 (assigned by HPA). The section
-on creating device files below also creates this device.
-
-After loading the sx.o module into your kernel, the driver will report
-the number of cards detected, but because it doesn't have any
-firmware, it will not be able to determine the number of ports. Only
-when you then run "sx_firmware" will the firmware be downloaded and
-the rest of the driver initialized. At that time the sx_firmware
-program will report the number of ports installed.
-
-In contrast with many other multi port serial cards, some of the data
-structures are only allocated when the card knows the number of ports
-that are connected. This means we won't waste memory for 120 port
-descriptor structures when you only have 8 ports. If you experience
-problems due to this, please report them: I haven't seen any.
-
-
-Interrupts
-==========
-
-A multi port serial card, would generate a horrendous amount of
-interrupts if it would interrupt the CPU for every received
-character. Even more than 10 years ago, the trick not to use
-interrupts but to poll the serial cards was invented.
-
-The SX card allow us to do this two ways. First the card limits its
-own interrupt rate to a rate that won't overwhelm the CPU. Secondly,
-we could forget about the cards interrupt completely and use the
-internal timer for this purpose.
-
-Polling the card can take up to a few percent of your CPU. Using the
-interrupts would be better if you have most of the ports idle. Using
-timer-based polling is better if your card almost always has work to
-do. You save the separate interrupt in that case.
-
-In any case, it doesn't really matter all that much.
-
-The most common problem with interrupts is that for ISA cards in a PCI
-system the BIOS has to be told to configure that interrupt as "legacy
-ISA". Otherwise the card can pull on the interrupt line all it wants
-but the CPU won't see this.
-
-If you can't get the interrupt to work, remember that polling mode is
-more efficient (provided you actually use the card intensively).
-
-
-Allowed Configurations
-======================
-
-Some configurations are disallowed. Even though at a glance they might
-seem to work, they are known to lockup the bus between the host card
-and the device concentrators. You should respect the drivers decision
-not to support certain configurations. It's there for a reason.
-
-Warning: Seriously technical stuff ahead. Executive summary: Don't use
-SX cards except configured at a 64k boundary. Skip the next paragraph.
-
-The SX cards can theoretically be placed at a 32k boundary. So for
-instance you can put an SX card at 0xc8000-0xd7fff. This is not a
-"recommended configuration". ISA cards have to tell the bus controller
-how they like their timing. Due to timing issues they have to do this
-based on which 64k window the address falls into. This means that the
-32k window below and above the SX card have to use exactly the same
-timing as the SX card. That reportedly works for other SX cards. But
-you're still left with two useless 32k windows that should not be used
-by anybody else.
-
-
-Configuring the driver
-======================
-
-PCI cards are always detected. The driver auto-probes for ISA cards at
-some sensible addresses. Please report if the auto-probe causes trouble
-in your system, or when a card isn't detected.
-
-I'm afraid I haven't implemented "kernel command line parameters" yet.
-This means that if the default doesn't work for you, you shouldn't use
-the compiled-into-the-kernel version of the driver. Use a module
-instead. If you convince me that you need this, I'll make it for
-you. Deal?
-
-I'm afraid that the module parameters are a bit clumsy. If you have a
-better idea, please tell me.
-
-You can specify several parameters:
-
- sx_poll: number of jiffies between timer-based polls.
-
- Set this to "0" to disable timer based polls.
- Initialization of cards without a working interrupt
- will fail.
-
- Set this to "1" if you want a polling driver.
- (on Intel: 100 polls per second). If you don't use
- fast baud rates, you might consider a value like "5".
- (If you don't know how to do the math, use 1).
-
- sx_slowpoll: Number of jiffies between timer-based polls.
- Set this to "100" to poll once a second.
- This should get the card out of a stall if the driver
- ever misses an interrupt. I've never seen this happen,
- and if it does, that's a bug. Tell me.
-
- sx_maxints: Number of interrupts to request from the card.
- The card normally limits interrupts to about 100 per
- second to offload the host CPU. You can increase this
- number to reduce latency on the card a little.
- Note that if you give a very high number you can overload
- your CPU as well as the CPU on the host card. This setting
- is inaccurate and not recommended for SI cards (But it
- works).
-
- sx_irqmask: The mask of allowable IRQs to use. I suggest you set
- this to 0 (disable IRQs all together) and use polling if
- the assignment of IRQs becomes problematic. This is defined
- as the sum of (1 << irq) 's that you want to allow. So
- sx_irqmask of 8 (1 << 3) specifies that only irq 3 may
- be used by the SX driver. If you want to specify to the
- driver: "Either irq 11 or 12 is ok for you to use", then
- specify (1 << 11) | (1 << 12) = 0x1800 .
-
- sx_debug: You can enable different sorts of debug traces with this.
- At "-1" all debugging traces are active. You'll get several
- times more debugging output than you'll get characters
- transmitted.
-
-
-Baud rates
-==========
-
-Theoretically new SXDCs should be capable of more than 460k
-baud. However the line drivers usually give up before that. Also the
-CPU on the card may not be able to handle 8 channels going at full
-blast at that speed. Moreover, the buffers are not large enough to
-allow operation with 100 interrupts per second. You'll have to realize
-that the card has a 256 byte buffer, so you'll have to increase the
-number of interrupts per second if you have more than 256*100 bytes
-per second to transmit. If you do any performance testing in this
-area, I'd be glad to hear from you...
-
-(Psst Linux users..... I think the Linux driver is more efficient than
-the driver for other OSes. If you can and want to benchmark them
-against each other, be my guest, and report your findings...... :-)
-
-
-Ports and devices
-=================
-
-Port 0 is the top connector on the module closest to the host
-card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8
-instead of from 0 to 7, as they are numbered by linux. I'm stubborn in
-this: I know for sure that I wouldn't be able to calculate which port
-is which anymore if I would change that....
-
-
-Devices:
-
-You should make the device files as follows:
-
-#!/bin/sh
-# (I recommend that you cut-and-paste this into a file and run that)
-cd /dev
-t=0
-mknod specialix_sxctl c 10 167
-while [ $t -lt 64 ]
- do
- echo -n "$t "
- mknod ttyX$t c 32 $t
- mknod cux$t c 33 $t
- t=`expr $t + 1`
-done
-echo ""
-rm /etc/psdevtab
-ps > /dev/null
-
-
-This creates 64 devices. If you have more, increase the constant on
-the line with "while". The devices start at 0, as is customary on
-Linux. Specialix seems to like starting the numbering at 1.
-
-If your system doesn't come with these devices pre-installed, bug your
-linux-vendor about this. They should have these devices
-"pre-installed" before the new millennium. The "ps" stuff at the end
-is to "tell" ps that the new devices exist.
-
-Officially the maximum number of cards per computer is 4. This driver
-however supports as many cards in one machine as you want. You'll run
-out of interrupts after a few, but you can switch to polled operation
-then. At about 256 ports (More than 8 cards), we run out of minor
-device numbers. Sorry. I suggest you buy a second computer.... (Or
-switch to RIO).
-
-------------------------------------------------------------------------
-
-
- Fixed bugs and restrictions:
- - Hangup processing.
- -- Done.
-
- - the write path in generic_serial (lockup / oops).
- -- Done (Ugly: not the way I want it. Copied from serial.c).
-
- - write buffer isn't flushed at close.
- -- Done. I still seem to lose a few chars at close.
- Sorry. I think that this is a firmware issue. (-> Specialix)
-
- - drain hardware before changing termios
- - Change debug on the fly.
- - ISA free irq -1. (no firmware loaded).
- - adding c8000 as a probe address. Added warning.
- - Add a RAMtest for the RAM on the card.c
- - Crash when opening a port "way" of the number of allowed ports.
- (for example opening port 60 when there are only 24 ports attached)
- - Sometimes the use-count strays a bit. After a few hours of
- testing the use count is sometimes "3". If you are not like
- me and can remember what you did to get it that way, I'd
- appreciate an Email. Possibly fixed. Tell me if anyone still
- sees this.
- - TAs don't work right if you don't connect all the modem control
- signals. SXDCs do. T225 firmware problem -> Specialix.
- (Mostly fixed now, I think. Tell me if you encounter this!)

+---------------------------------------------------------------------
+
+在某些平台上，所谓的内存映射I/O是弱顺序。在这些平台上，驱动开发者有责任
+保证I/O内存映射地址的写操作按程序图意的顺序达到设备。通常读取一个“安全”
+设备寄存器或桥寄存器，触发IO芯片清刷未处理的写操作到达设备后才处理读操作，
+而达到保证目的。驱动程序通常在spinlock保护的临界区退出之前使用这种技术。
+这也可以保证后面的写操作只在前面的写操作之后到达设备（这非常类似于内存
+屏障操作，mb()，不过仅适用于I/O）。
+
+假设一个设备驱动程的具体例子：
+
+ ...
+CPU A: spin_lock_irqsave(&dev_lock, flags)
+CPU A: val = readl(my_status);
+CPU A: ...
+CPU A: writel(newval, ring_ptr);
+CPU A: spin_unlock_irqrestore(&dev_lock, flags)
+ ...
+CPU B: spin_lock_irqsave(&dev_lock, flags)
+CPU B: val = readl(my_status);
+CPU B: ...
+CPU B: writel(newval2, ring_ptr);
+CPU B: spin_unlock_irqrestore(&dev_lock, flags)
+ ...
+
+上述例子中，设备可能会先接收到newval2的值，然后接收到newval的值，问题就
+发生了。不过很容易通过下面方法来修复：
+
+ ...
+CPU A: spin_lock_irqsave(&dev_lock, flags)
+CPU A: val = readl(my_status);
+CPU A: ...
+CPU A: writel(newval, ring_ptr);
+CPU A: (void)readl(safe_register); /* 配置寄存器？*/
+CPU A: spin_unlock_irqrestore(&dev_lock, flags)
+ ...
+CPU B: spin_lock_irqsave(&dev_lock, flags)
+CPU B: val = readl(my_status);
+CPU B: ...
+CPU B: writel(newval2, ring_ptr);
+CPU B: (void)readl(safe_register); /* 配置寄存器？*/
+CPU B: spin_unlock_irqrestore(&dev_lock, flags)
+
+在解决方案中，读取safe_register寄存器，触发IO芯片清刷未处理的写操作，
+再处理后面的读操作，防止引发数据不一致问题。

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts. The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames. With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.

- tristate "Support for frame buffer devices"
- ---help---
- The frame buffer device provides an abstraction for the graphics
- hardware. It represents the frame buffer of some video hardware and
- allows application software to access the graphics hardware through
- a well-defined interface, so the software doesn't need to know
- anything about the low-level (hardware register) stuff.
-
- Frame buffer devices work identically across the different
- architectures supported by Linux and make the implementation of
- application programs easier and more portable; at this point, an X
- server exists which uses the frame buffer device exclusively.
- On several non-X86 architectures, the frame buffer device is the
- only way to use the graphics hardware.
-
- The device is accessed through special device nodes, usually located
- in the /dev directory, i.e. /dev/fb*.
-
- You need an utility program called fbset to make full use of frame
- buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
- and the Framebuffer-HOWTO at
- <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
- information.
-
- Say Y here and to the driver for your graphics board below if you
- are compiling a kernel for a non-x86 architecture.
-
- If you are compiling for the x86 architecture, you can say Y if you
- want to play with it, but it is not essential. Please note that
- running graphical applications that directly touch the hardware
- (e.g. an accelerated X server) and that are not frame buffer
- device-aware may cause unexpected results. If unsure, say N.

- transfers do not work for your driver and if you are using
- nvidiafb, i810fb or savagefb.
-
- In general, choosing Y for this option is safe. If you
- experience extremely long delays while booting before you get

- the standard blitting divides the screen into pixels. Because the
- default drawing element is a tile, drawing functions will be passed
- parameters in terms of number of tiles instead of number of pixels.
- For example, to draw a single character, instead of using bitmaps,
- an index to an array of bitmaps will be used. To clear or move a
- rectangular section of a screen, the rectangle will be described in
- terms of number of tiles in the x- and y-axis.

- depends on FB_I810
- help
- If you say Y, then the VESA standard, Generalized Timing Formula
- or GTF, will be used to calculate the required video timing values
- per video mode. Since the GTF allows nondiscrete timings
- (nondiscrete being a range of values as opposed to discrete being a
- set of values), you'll be able to use any combination of horizontal
- and vertical resolutions, and vertical refresh rates without having
- to specify your own timing parameters. This is especially useful
- to maximize the performance of an aging display, or if you just
- have a display with nonstandard dimensions. A VESA compliant
- monitor is recommended, but can still work with non-compliant ones.
- If you need or want this, then select this option. The timings may
- not be compliant with Intel's recommended values. Use at your own
- risk.
-
- If you say N, the driver will revert to discrete video timings
- using a set recommended by Intel in their documentation.
-
- If unsure, say N.

+menuconfig FB
+ tristate "Support for frame buffer devices"
+ ---help---
+ The frame buffer device provides an abstraction for the graphics
+ hardware. It represents the frame buffer of some video hardware and
+ allows application software to access the graphics hardware through
+ a well-defined interface, so the software doesn't need to know
+ anything about the low-level (hardware register) stuff.
+
+ Frame buffer devices work identically across the different
+ architectures supported by Linux and make the implementation of
+ application programs easier and more portable; at this point, an X
+ server exists which uses the frame buffer device exclusively.
+ On several non-X86 architectures, the frame buffer device is the
+ only way to use the graphics hardware.
+
+ The device is accessed through special device nodes, usually located
+ in the /dev directory, i.e. /dev/fb*.
+
+ You need an utility program called fbset to make full use of frame
+ buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
+ and the Framebuffer-HOWTO at
+ <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
+ information.
+
+ Say Y here and to the driver for your graphics board below if you
+ are compiling a kernel for a non-x86 architecture.
+
+ If you are compiling for the x86 architecture, you can say Y if you
+ want to play with it, but it is not essential. Please note that
+ running graphical applications that directly touch the hardware
+ (e.g. an accelerated X server) and that are not frame buffer
+ device-aware may cause unexpected results. If unsure, say N.
+
+config FIRMWARE_EDID

+ ---help---
+ This enables access to the EDID transferred from the firmware.
+ On the i386, this is from the Video BIOS. Enable this if DDC/I2C
+ transfers do not work for your driver and if you are using
+ nvidiafb, i810fb or savagefb.
+
+ In general, choosing Y for this option is safe. If you
+ experience extremely long delays while booting before you get
+ something on your display, try setting this to N. Matrox cards in
+ combination with certain motherboards and monitors are known to
+ suffer from this problem.

+ just increase the kernel size by about 5K.
+
+config FB_TILEBLITTING
+ bool "Enable Tile Blitting Support"
+ depends on FB
+ default n
+ ---help---
+ This enables tile blitting. Tile blitting is a drawing technique
+ where the screen is divided into rectangular sections (tiles), whereas
+ the standard blitting divides the screen into pixels. Because the
+ default drawing element is a tile, drawing functions will be passed
+ parameters in terms of number of tiles instead of number of pixels.
+ For example, to draw a single character, instead of using bitmaps,
+ an index to an array of bitmaps will be used. To clear or move a
+ rectangular section of a screen, the rectangle will be described in
+ terms of number of tiles in the x- and y-axis.
+
+ This is particularly important to one driver, matroxfb. If
+ unsure, say N.

* The TIPC locking policy is designed to ensure a very fine locking
* granularity, permitting complete parallel access to individual
- * port and node/link instances. The code consists of three major
+ * port and node/link instances. The code consists of four major
* locking domains, each protected with their own disjunct set of locks.
*
- * 1: The routing hierarchy.
- * Comprises the structures 'zone', 'cluster', 'node', 'link'
- * and 'bearer'. The whole hierarchy is protected by a big
- * read/write lock, tipc_net_lock, to enssure that nothing is added
- * or removed while code is accessing any of these structures.
- * This layer must not be called from the two others while they
- * hold any of their own locks.
- * Neither must it itself do any upcalls to the other two before
- * it has released tipc_net_lock and other protective locks.
+ * 1: The bearer level.
+ * RTNL lock is used to serialize the process of configuring bearer
+ * on update side, and RCU lock is applied on read side to make
+ * bearer instance valid on both paths of message transmission and
+ * reception.
*
- * Within the tipc_net_lock domain there are two sub-domains;'node' and
- * 'bearer', where local write operations are permitted,
- * provided that those are protected by individual spin_locks
- * per instance. Code holding tipc_net_lock(read) and a node spin_lock
- * is permitted to poke around in both the node itself and its
- * subordinate links. I.e, it can update link counters and queues,
- * change link state, send protocol messages, and alter the
- * "active_links" array in the node; but it can _not_ remove a link
- * or a node from the overall structure.
- * Correspondingly, individual bearers may change status within a
- * tipc_net_lock(read), protected by an individual spin_lock ber bearer
- * instance, but it needs tipc_net_lock(write) to remove/add any bearers.
+ * 2: The node and link level.
+ * All node instances are saved into two tipc_node_list and node_htable
+ * lists. The two lists are protected by node_list_lock on write side,
+ * and they are guarded with RCU lock on read side. Especially node
+ * instance is destroyed only when TIPC module is removed, and we can
+ * confirm that there has no any user who is accessing the node at the
+ * moment. Therefore, Except for iterating the two lists within RCU
+ * protection, it's no needed to hold RCU that we access node instance
+ * in other places.
*
+ * In addition, all members in node structure including link instances
+ * are protected by node spin lock.
*
- * 2: The transport level of the protocol.
- * This consists of the structures port, (and its user level
- * representations, such as user_port and tipc_sock), reference and
- * tipc_user (port.c, reg.c, socket.c).
+ * 3: The transport level of the protocol.
+ * This consists of the structures port, (and its user level
+ * representations, such as user_port and tipc_sock), reference and
