+ UHID - User-space I/O driver support for HID subsystem
+ ========================================================
+
+The HID subsystem needs two kinds of drivers. In this document we call them:
+
+ 1. The "HID I/O Driver" is the driver that performs raw data I/O to the
+ low-level device. Internally, they register an hid_ll_driver structure with
+ the HID core. They perform device setup, read raw data from the device and
+ push it into the HID subsystem and they provide a callback so the HID
+ subsystem can send data to the device.
+
+ 2. The "HID Device Driver" is the driver that parses HID reports and reacts on
+ them. There are generic drivers like "generic-usb" and "generic-bluetooth"
+ which adhere to the HID specification and provide the standardizes features.
+ But there may be special drivers and quirks for each non-standard device out
+ there. Internally, they use the hid_driver structure.
+
+Historically, the USB stack was the first subsystem to provide an HID I/O
+Driver. However, other standards like Bluetooth have adopted the HID specs and
+may provide HID I/O Drivers, too. The UHID driver allows to implement HID I/O
+Drivers in user-space and feed the data into the kernel HID-subsystem.
+
+This allows user-space to operate on the same level as USB-HID, Bluetooth-HID
+and similar. It does not provide a way to write HID Device Drivers, though. Use
+hidraw for this purpose.
+
+There is an example user-space application in ./samples/uhid/uhid-example.c
+
+The UHID API
+------------
+
+UHID is accessed through a character misc-device. The minor-number is allocated
+dynamically so you need to rely on udev (or similar) to create the device node.
+This is /dev/uhid by default.
+
+If a new device is detected by your HID I/O Driver and you want to register this
+device with the HID subsystem, then you need to open /dev/uhid once for each
+device you want to register. All further communication is done by read()'ing or
+write()'ing "struct uhid_event" objects. Non-blocking operations are supported
+by setting O_NONBLOCK.
+
+struct uhid_event {
+ __u32 type;
+ union {
+ struct uhid_create_req create;
+ struct uhid_data_req data;
+ ...
+ } u;
+};
+
+The "type" field contains the ID of the event. Depending on the ID different
+payloads are sent. You must not split a single event across multiple read()'s or
+multiple write()'s. A single event must always be sent as a whole. Furthermore,
+only a single event can be sent per read() or write(). Pending data is ignored.
+If you want to handle multiple events in a single syscall, then use vectored
+I/O with readv()/writev().
+
+The first thing you should do is sending an UHID_CREATE event. This will
+register the device. UHID will respond with an UHID_START event. You can now
+start sending data to and reading data from UHID. However, unless UHID sends the
+UHID_OPEN event, the internally attached HID Device Driver has no user attached.
+That is, you might put your device asleep unless you receive the UHID_OPEN
+event. If you receive the UHID_OPEN event, you should start I/O. If the last
+user closes the HID device, you will receive an UHID_CLOSE event. This may be
+followed by an UHID_OPEN event again and so on. There is no need to perform
+reference-counting in user-space. That is, you will never receive multiple
+UHID_OPEN events without an UHID_CLOSE event. The HID subsystem performs
+ref-counting for you.
+You may decide to ignore UHID_OPEN/UHID_CLOSE, though. I/O is allowed even
+though the device may have no users.
+
+If you want to send data to the HID subsystem, you send an HID_INPUT event with
+your raw data payload. If the kernel wants to send data to the device, you will
+read an UHID_OUTPUT or UHID_OUTPUT_EV event.
+
+If your device disconnects, you should send an UHID_DESTROY event. This will
+unregister the device. You can now send UHID_CREATE again to register a new
+device.
+If you close() the fd, the device is automatically unregistered and destroyed
+internally.
+
+write()
+-------
+write() allows you to modify the state of the device and feed input data into
+the kernel. The following types are supported: UHID_CREATE, UHID_DESTROY and
+UHID_INPUT. The kernel will parse the event immediately and if the event ID is
+not supported, it will return -EOPNOTSUPP. If the payload is invalid, then
+-EINVAL is returned, otherwise, the amount of data that was read is returned and
+the request was handled successfully.
+
+ UHID_CREATE:
+ This creates the internal HID device. No I/O is possible until you send this
+ event to the kernel. The payload is of type struct uhid_create_req and
+ contains information about your device. You can start I/O now.
+
+ UHID_DESTROY:
+ This destroys the internal HID device. No further I/O will be accepted. There
+ may still be pending messages that you can receive with read() but no further
+ UHID_INPUT events can be sent to the kernel.
+ You can create a new device by sending UHID_CREATE again. There is no need to
+ reopen the character device.
+
+ UHID_INPUT:
+ You must send UHID_CREATE before sending input to the kernel! This event
+ contains a data-payload. This is the raw data that you read from your device.
+ The kernel will parse the HID reports and react on it.
+
+ UHID_FEATURE_ANSWER:
+ If you receive a UHID_FEATURE request you must answer with this request. You
+ must copy the "id" field from the request into the answer. Set the "err" field
+ to 0 if no error occured or to EIO if an I/O error occurred.
+ If "err" is 0 then you should fill the buffer of the answer with the results
+ of the feature request and set "size" correspondingly.
+
+read()
+------
+read() will return a queued ouput report. These output reports can be of type
+UHID_START, UHID_STOP, UHID_OPEN, UHID_CLOSE, UHID_OUTPUT or UHID_OUTPUT_EV. No
+reaction is required to any of them but you should handle them according to your
+needs. Only UHID_OUTPUT and UHID_OUTPUT_EV have payloads.
+
+ UHID_START:
+ This is sent when the HID device is started. Consider this as an answer to
+ UHID_CREATE. This is always the first event that is sent.
+
+ UHID_STOP:
+ This is sent when the HID device is stopped. Consider this as an answer to
+ UHID_DESTROY.
+ If the kernel HID device driver closes the device manually (that is, you
+ didn't send UHID_DESTROY) then you should consider this device closed and send
+ an UHID_DESTROY event. You may want to reregister your device, though. This is
+ always the last message that is sent to you unless you reopen the device with
+ UHID_CREATE.
+
+ UHID_OPEN:
+ This is sent when the HID device is opened. That is, the data that the HID
+ device provides is read by some other process. You may ignore this event but
+ it is useful for power-management. As long as you haven't received this event
+ there is actually no other process that reads your data so there is no need to
+ send UHID_INPUT events to the kernel.
+
+ UHID_CLOSE:
+ This is sent when there are no more processes which read the HID data. It is
+ the counterpart of UHID_OPEN and you may as well ignore this event.
+
+ UHID_OUTPUT:
+ This is sent if the HID device driver wants to send raw data to the I/O
+ device. You should read the payload and forward it to the device. The payload
+ is of type "struct uhid_data_req".
+ This may be received even though you haven't received UHID_OPEN, yet.
+
+ UHID_OUTPUT_EV:
+ Same as UHID_OUTPUT but this contains a "struct input_event" as payload. This
+ is called for force-feedback, LED or similar events which are received through
+ an input device by the HID subsystem. You should convert this into raw reports
+ and send them to your device similar to events of type UHID_OUTPUT.
+
+ UHID_FEATURE:
+ This event is sent if the kernel driver wants to perform a feature request as
+ described in the HID specs. The report-type and report-number are available in
+ the payload.
+ The kernel serializes feature requests so there will never be two in parallel.
+ However, if you fail to respond with a UHID_FEATURE_ANSWER in a time-span of 5
+ seconds, then the requests will be dropped and a new one might be sent.
+ Therefore, the payload also contains an "id" field that identifies every
+ request.

+
+Description
+-----------
+
+The DA9052/53 provides an Analogue to Digital Converter (ADC) with 10 bits
+resolution and track and hold circuitry combined with an analogue input
+multiplexer. The analogue input multiplexer will allow conversion of up to 10
+different inputs. The track and hold circuit ensures stable input voltages at
+the input of the ADC during the conversion.
+
+The ADC is used to measure the following inputs:
+Channel 0: VDDOUT - measurement of the system voltage
+Channel 1: ICH - internal battery charger current measurement
+Channel 2: TBAT - output from the battery NTC
+Channel 3: VBAT - measurement of the battery voltage
+Channel 4: ADC_IN4 - high impedance input (0 - 2.5V)
+Channel 5: ADC_IN5 - high impedance input (0 - 2.5V)
+Channel 6: ADC_IN6 - high impedance input (0 - 2.5V)
+Channel 7: XY - TSI interface to measure the X and Y voltage of the touch
+ screen resistive potentiometers
+Channel 8: Internal Tjunc. - sense (internal temp. sensor)
+Channel 9: VBBAT - measurement of the backup battery voltage
+
+By using sysfs attributes we can measure the system voltage VDDOUT, the battery
+charging current ICH, battery temperature TBAT, battery junction temperature
+TJUNC, battery voltage VBAT and the back up battery voltage VBBAT.
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by a 10 bit ADC.
+
+The battery voltage is calculated as:
+ Milli volt = ((ADC value * 1000) / 512) + 2500
+
+The backup battery voltage is calculated as:
+ Milli volt = (ADC value * 2500) / 512;
+
+The voltages on ADC channels 4, 5 and 6 are calculated as:
+ Milli volt = (ADC value * 2500) / 1023
+
+Temperature Monitoring
+----------------------
+
+Temperatures are sampled by a 10 bit ADC. Junction and battery temperatures
+are monitored by the ADC channels.
+
+The junction temperature is calculated:
+ Degrees celsius = 1.708 * (TJUNC_RES - T_OFFSET) - 108.8
+The junction temperature attribute is supported by the driver.
+
+The battery temperature is calculated:
+ Degree Celcius = 1 / (t1 + 1/298)- 273
+where t1 = (1/B)* ln(( ADCval * 2.5)/(R25*ITBAT*255))
+Default values of R25, B, ITBAT are 10e3, 3380 and 50e-6 respectively.

+ The struct canfd_frame and the existing struct can_frame have the can_id,

+ When the content of a struct can_frame is copied into a struct canfd_frame
+ all structure elements can be used as-is - only the data[] becomes extended.
+
+ When introducing the struct canfd_frame it turned out that the data length
+ code (DLC) of the struct can_frame was used as a length information as the
+ length and the DLC has a 1:1 mapping in the range of 0 .. 8. To preserve
+ the easy handling of the length information the canfd_frame.len element
+ contains a plain length value from 0 .. 64. So both canfd_frame.len and
+ can_frame.can_dlc are equal and contain a length information and no DLC.
+ For details about the distinction of CAN and CAN FD capable devices and
+ the mapping to the bus-relevant data length code (DLC), see chapter 6.6.

+ 4.1.5 RAW socket option CAN_RAW_FD_FRAMES
+
+ CAN FD support in CAN_RAW sockets can be enabled with a new socket option
+ CAN_RAW_FD_FRAMES which is off by default. When the new socket option is
+ not supported by the CAN_RAW socket (e.g. on older kernels), switching the
+ CAN_RAW_FD_FRAMES option returns the error -ENOPROTOOPT.
+
+ Once CAN_RAW_FD_FRAMES is enabled the application can send both CAN frames
+ and CAN FD frames. OTOH the application has to handle CAN and CAN FD frames
+ when reading from the socket.
+
+ CAN_RAW_FD_FRAMES enabled: CAN_MTU and CANFD_MTU are allowed
+ CAN_RAW_FD_FRAMES disabled: only CAN_MTU is allowed (default)
+
+ Example:
+ [ remember: CANFD_MTU == sizeof(struct canfd_frame) ]
+
+ struct canfd_frame cfd;
+
+ nbytes = read(s, &cfd, CANFD_MTU);
+
+ if (nbytes == CANFD_MTU) {
+ printf("got CAN FD frame with length %d\n", cfd.len);
+ /* cfd.flags contains valid data */
+ } else if (nbytes == CAN_MTU) {
+ printf("got legacy CAN frame with length %d\n", cfd.len);
+ /* cfd.flags is undefined */
+ } else {
+ fprintf(stderr, "read: invalid CAN(FD) frame\n");
+ return 1;
+ }
+
+ /* the content can be handled independently from the received MTU size */
+
+ printf("can_id: %X data length: %d data: ", cfd.can_id, cfd.len);
+ for (i = 0; i < cfd.len; i++)
+ printf("%02X ", cfd.data[i]);
+
+ When reading with size CANFD_MTU only returns CAN_MTU bytes that have
+ been received from the socket a legacy CAN frame has been read into the
+ provided CAN FD structure. Note that the canfd_frame.flags data field is
+ not specified in the struct can_frame and therefore it is only valid in
+ CANFD_MTU sized CAN FD frames.
+
+ As long as the payload length is <=8 the received CAN frames from CAN FD
+ capable CAN devices can be received and read by legacy sockets too. When
+ user-generated CAN FD frames have a payload length <=8 these can be send
+ by legacy CAN network interfaces too. Sending CAN FD frames with payload
+ length > 8 to a legacy CAN network interface returns an -EMSGSIZE error.
+
+ Implementation hint for new CAN applications:
+
+ To build a CAN FD aware application use struct canfd_frame as basic CAN
+ data structure for CAN_RAW based applications. When the application is
+ executed on an older Linux kernel and switching the CAN_RAW_FD_FRAMES
+ socket option returns an error: No problem. You'll get legacy CAN frames
+ or CAN FD frames and can process them the same way.
+
+ When sending to CAN devices make sure that the device is capable to handle
+ CAN FD frames by checking if the device maximum transfer unit is CANFD_MTU.
+ The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.

+Errors that occur synchronously with the execution of an NFC Core request are

+Errors that occur asynchronously (e.g. in a background protocol handling thread)

+Handling of these errors is done as follows:
+
+- driver (pn544) fails to deliver an incoming frame: it stores the error such
+that any subsequent call to the driver will result in this error. Then it calls
+the standard nfc_shdlc_recv_frame() with a NULL argument to report the problem
+above. shdlc stores a EREMOTEIO sticky status, which will trigger SMW to
+report above in turn.
+
+- SMW is basically a background thread to handle incoming and outgoing shdlc
+frames. This thread will also check the shdlc sticky status and report to HCI
+when it discovers it is not able to run anymore because of an unrecoverable
+error that happened within shdlc or below. If the problem occurs during shdlc
+connection, the error is reported through the connect completion.
+
+- HCI: if an internal HCI error happens (frame is lost), or HCI is reported an
+error from a lower layer, HCI will either complete the currently executing
+command with that error, or notify NFC Core directly if no command is executing.
+
+- NFC Core: when NFC Core is notified of an error from below and polling is

+space to let it know that the poll operation will never be able to detect a tag.
+If polling is not active and the error was sticky, lower levels will return it

+- SPTE_MMU_WRITEABLE means the gfn is writable on mmu. The bit is set when
+ the gfn is writable on guest mmu and it is not write-protected by shadow
+ page write-protection.
+
+On fast page fault path, we will use cmpxchg to atomically set the spte W
+bit if spte.SPTE_HOST_WRITEABLE = 1 and spte.SPTE_WRITE_PROTECT = 1, this
+is safe because whenever changing these bits can be detected by cmpxchg.
+
+But we need carefully check these cases:
+1): The mapping from gfn to pfn
+The mapping from gfn to pfn may be changed since we can only ensure the pfn
+is not changed during cmpxchg. This is a ABA problem, for example, below case
+will happen:
+
+At the beginning:
+gpte = gfn1
+gfn1 is mapped to pfn1 on host
+spte is the shadow page table entry corresponding with gpte and
+spte = pfn1
+
+ VCPU 0 VCPU0
+on fast page fault path:
+
+ old_spte = *spte;
+ pfn1 is swapped out:
+ spte = 0;
+
+ pfn1 is re-alloced for gfn2.
+
+ gpte is changed to point to
+ gfn2 by the guest:
+ spte = pfn1;
+
+ if (cmpxchg(spte, old_spte, old_spte+W)
+ mark_page_dirty(vcpu->kvm, gfn1)
+ OOPS!!!
+
+We dirty-log for gfn1, that means gfn2 is lost in dirty-bitmap.
+
+For direct sp, we can easily avoid it since the spte of direct sp is fixed
+to gfn. For indirect sp, before we do cmpxchg, we call gfn_to_pfn_atomic()
+to pin gfn to pfn, because after gfn_to_pfn_atomic():
+- We have held the refcount of pfn that means the pfn can not be freed and
+ be reused for another gfn.
+- The pfn is writable that means it can not be shared between different gfns
+ by KSM.
+
+Then, we can ensure the dirty bitmaps is correctly set for a gfn.
+
+Currently, to simplify the whole things, we disable fast page fault for
+indirect shadow page.
+
+2): Dirty bit tracking
+In the origin code, the spte can be fast updated (non-atomically) if the
+spte is read-only and the Accessed bit has already been set since the
+Accessed bit and Dirty bit can not be lost.
+
+But it is not true after fast page fault since the spte can be marked
+writable between reading spte and updating spte. Like below case:
+
+At the beginning:
+spte.W = 0
+spte.Accessed = 1
+
+ VCPU 0 VCPU0
+In mmu_spte_clear_track_bits():
+
+ old_spte = *spte;
+
+ /* 'if' condition is satisfied. */
+ if (old_spte.Accssed == 1 &&
+ old_spte.W == 0)
+ spte = 0ull;
+ on fast page fault path:
+ spte.W = 1
+ memory write on the spte:
+ spte.Dirty = 1
+
+
+ else
+ old_spte = xchg(spte, 0ull)
+
+
+ if (old_spte.Accssed == 1)
+ kvm_set_pfn_accessed(spte.pfn);
+ if (old_spte.Dirty == 1)
+ kvm_set_pfn_dirty(spte.pfn);
+ OOPS!!!
+
+The Dirty bit is lost in this case.
+
+In order to avoid this kind of issue, we always treat the spte as "volatile"
+if it can be updated out of mmu-lock, see spte_has_volatile_bits(), it means,
+the spte is always atomicly updated in this case.
+
+3): flush tlbs due to spte updated
+If the spte is updated from writable to readonly, we should flush all TLBs,
+otherwise rmap_write_protect will find a read-only spte, even though the
+writable spte might be cached on a CPU's TLB.
+
+As mentioned before, the spte can be updated to writable out of mmu-lock on
+fast page fault path, in order to easily audit the path, we see if TLBs need
+be flushed caused by this reason in mmu_spte_update() since this is a common
+function to update spte (present -> present).
+
+Since the spte is "volatile" if it can be updated out of mmu-lock, we always
+atomicly update the spte, the race caused by fast page fault can be avoided,
+See the comments in spte_has_volatile_bits() and mmu_spte_update().

+MSR_KVM_EOI_EN: 0x4b564d04
+ data: Bit 0 is 1 when PV end of interrupt is enabled on the vcpu; 0
+ when disabled. Bit 1 is reserved and must be zero. When PV end of
+ interrupt is enabled (bit 0 set), bits 63-2 hold a 4-byte aligned
+ physical address of a 4 byte memory area which must be in guest RAM and
+ must be zeroed.
+
+ The first, least significant bit of 4 byte memory location will be
+ written to by the hypervisor, typically at the time of interrupt
+ injection. Value of 1 means that guest can skip writing EOI to the apic
+ (using MSR or MMIO write); instead, it is sufficient to signal
+ EOI by clearing the bit in guest memory - this location will
+ later be polled by the hypervisor.
+ Value of 0 means that the EOI write is required.
+
+ It is always safe for the guest to ignore the optimization and perform
+ the APIC EOI write anyway.
+
+ Hypervisor is guaranteed to only modify this least
+ significant bit while in the current VCPU context, this means that
+ guest does not need to use either lock prefix or memory ordering
+ primitives to synchronise with the hypervisor.
+
+ However, hypervisor can set and clear this memory bit at any time:
+ therefore to make sure hypervisor does not interrupt the
+ guest and clear the least significant bit in the memory area
+ in the window between guest testing it to detect
+ whether it can skip EOI apic write and between guest
+ clearing it to signal EOI to the hypervisor,
+ guest must both read the least significant bit in the memory area and
+ clear it using a single CPU instruction, such as test and clear, or
+ compare and exchange.

+ * The pfn containing the shared_info is located somewhere in RAM. This
+ * will cause trouble if the current kernel is doing a kexec boot into a
+ * new kernel. The new kernel (and its startup code) can not know where
+ * the pfn is, so it can not reserve the page. The hypervisor will
+ * continue to update the pfn, and as a result memory corruption occours
+ * in the new kernel.
+ *
+ * One way to work around this issue is to allocate a page in the
+ * xen-platform pci device's BAR memory range. But pci init is done very
+ * late and the shared_info page is already in use very early to read
+ * the pvclock. So moving the pfn from RAM to MMIO is racy because some
+ * code paths on other vcpus could access the pfn during the small
+ * window when the old pfn is moved to the new pfn. There is even a
+ * small window were the old pfn is not backed by a mfn, and during that
+ * time all reads return -1.
+ *
+ * Because it is not known upfront where the MMIO region is located it
+ * can not be used right from the start in xen_hvm_init_shared_info.
+ *
+ * To minimise trouble the move of the pfn is done shortly before kexec.
+ * This does not eliminate the race because all vcpus are still online
+ * when the syscore_ops will be called. But hopefully there is no work
+ * pending at this point in time. Also the syscore_op is run last which

- * THE PROCEDURE
- *
- * See fw.c for the generic description of this procedure.
- *
- * This file implements only the SDIO specifics. It boils down to how
- * to send a command and waiting for an acknowledgement from the
- * device.
- *
- * All this code is sequential -- all i2400ms_bus_bm_*() functions are
- * executed in the same thread, except i2400ms_bm_irq() [on its own by
- * the SDIO driver]. This makes it possible to avoid locking.
- *
- * COMMAND EXECUTION
- *
- * The generic firmware upload code will call i2400m_bus_bm_cmd_send()
- * to send commands.
- *
- * The SDIO devices expects things in 256 byte blocks, so it will pad
- * it, compute the checksum (if needed) and pass it to SDIO.
- *
- * ACK RECEPTION
- *
- * This works in IRQ mode -- the fw loader says when to wait for data
- * and for that it calls i2400ms_bus_bm_wait_for_ack().
- *
- * This checks if there is any data available (RX size > 0); if not,
- * waits for the IRQ handler to notify about it. Once there is data,
- * it is read and passed to the caller. Doing it this way we don't
- * need much coordination/locking, and it makes it much more difficult
- * for an interrupt to be lost and the wait_for_ack() function getting
- * stuck even when data is pending.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel. We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware. This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel. There is no corresponding channel information for that
- * entry.

- The Intel Wireless Multicomm 3200 hardware is a combo
- card with GPS, Bluetooth, WiMax and 802.11 radios. It
- runs over SDIO and is typically found on Moorestown
- based platform. This driver takes care of the 802.11

- You can set the debug level and module through debugfs. By
- default all modules are set to the IWL_DL_ERR level.
- To see the list of debug modules and levels, see iwm/debug.h
-
- For example, if you want the full MLME debug output:
- echo 0xff > /sys/kernel/debug/iwm/phyN/debug/mlme
-
- Or, if you want the full debug, for all modules:
- echo 0xff > /sys/kernel/debug/iwm/phyN/debug/level

-/*
- * Hardware Abstraction Layer for iwm.
- *
- * This file mostly defines an abstraction API for
- * sending various commands to the target.
- *
- * We have 2 types of commands: wifi and non-wifi ones.
- *
- * - wifi commands:
- * They are used for sending LMAC and UMAC commands,
- * and thus are the most commonly used ones.
- * There are 2 different wifi command types, the regular
- * one and the LMAC one. The former is used to send
- * UMAC commands (see UMAC_CMD_OPCODE_* from umac.h)
- * while the latter is used for sending commands to the
- * LMAC. If you look at LMAC commands you'll se that they
- * are actually regular iwlwifi target commands encapsulated
- * into a special UMAC command called UMAC passthrough.
- * This is due to the fact the host talks exclusively
- * to the UMAC and so there needs to be a special UMAC
- * command for talking to the LMAC.
- * This is how a wifi command is laid out:
- * ------------------------
- * | iwm_udma_out_wifi_hdr |
- * ------------------------
- * | SW meta_data (32 bits) |
- * ------------------------
- * | iwm_dev_cmd_hdr |
- * ------------------------
- * | payload |
- * | .... |
- *
- * - non-wifi, or general commands:
- * Those commands are handled by the device's bootrom,
- * and are typically sent when the UMAC and the LMAC
- * are not yet available.
- * * This is how a non-wifi command is laid out:
- * ---------------------------
- * | iwm_udma_out_nonwifi_hdr |
- * ---------------------------
- * | payload |
- * | .... |
-
- *
- * All the commands start with a UDMA header, which is
- * basically a 32 bits field. The 4 LSB there define
- * an opcode that allows the target to differentiate
- * between wifi (opcode is 0xf) and non-wifi commands
- * (opcode is [0..0xe]).
- *
- * When a command (wifi or non-wifi) is supposed to receive
- * an answer, we queue the command buffer. When we do receive
- * a command response from the UMAC, we go through the list
- * of pending command, and pass both the command and the answer
- * to the rx handler. Each command is sent with a unique
- * sequence id, and the answer is sent with the same one. This
- * is how we're supposed to match an answer with its command.
- * See rx.c:iwm_rx_handle_[non]wifi() and iwm_get_pending_[non]wifi()
- * for the implementation details.

- * iwm Tx theory of operation:
- *
- * 1) We receive a 802.3 frame from the stack
- * 2) We convert it to a 802.11 frame [iwm_xmit_frame]
- * 3) We queue it to its corresponding tx queue [iwm_xmit_frame]
- * 4) We schedule the tx worker. There is one worker per tx
- * queue. [iwm_xmit_frame]
- * 5) The tx worker is scheduled
- * 6) We go through every queued skb on the tx queue, and for each
- * and every one of them: [iwm_tx_worker]
- * a) We check if we have enough Tx credits (see below for a Tx
- * credits description) for the frame length. [iwm_tx_worker]
- * b) If we do, we aggregate the Tx frame into a UDMA one, by
- * concatenating one REPLY_TX command per Tx frame. [iwm_tx_worker]
- * c) When we run out of credits, or when we reach the maximum
- * concatenation size, we actually send the concatenated UDMA
- * frame. [iwm_tx_worker]
- *
- * When we run out of Tx credits, the skbs are filling the tx queue,
- * and eventually we will stop the netdev queue. [iwm_tx_worker]
- * The tx queue is emptied as we're getting new tx credits, by
- * scheduling the tx_worker. [iwm_tx_credit_inc]
- * The netdev queue is started again when we have enough tx credits,
- * and when our tx queue has some reasonable amout of space available
- * (i.e. half of the max size). [iwm_tx_worker]

- * Since we're on an SDIO or USB bus, we are not sharing memory
- * for storing to be transmitted frames. The host needs to push
- * them upstream. As a consequence there needs to be a way for
- * the target to let us know if it can actually take more TX frames
- * or not. This is what Tx credits are for.
- *
- * For each Tx HW queue, we have a Tx pool, and then we have one
- * unique super pool (spool), which is actually a global pool of
- * all the UMAC pages.
- * For each Tx pool we have a min_pages, a max_pages fields, and a
- * alloc_pages fields. The alloc_pages tracks the number of pages
- * currently allocated from the tx pool.
- * Here are the rules to check if given a tx frame we have enough
- * tx credits for it:
- * 1) We translate the frame length into a number of UMAC pages.
- * Let's call them n_pages.
- * 2) For the corresponding tx pool, we check if n_pages +
- * pool->alloc_pages is higher than pool->min_pages. min_pages
- * represent a set of pre-allocated pages on the tx pool. If
- * that's the case, then we need to allocate those pages from
- * the spool. We can do so until we reach spool->max_pages.
- * 3) Each tx pool is not allowed to allocate more than pool->max_pages
- * from the spool, so once we're over min_pages, we can allocate
- * pages from the spool, but not more than max_pages.
- *
- * When the tx code path needs to send a tx frame, it checks first
- * if it has enough tx credits, following those rules. [iwm_tx_credit_get]
- * If it does, it then updates the pool and spool counters and
- * then send the frame. [iwm_tx_credit_alloc and iwm_tx_credit_dec]
- * On the other side, when the UMAC is done transmitting frames, it
- * will send a credit update notification to the host. This is when
- * the pool and spool counters gets to be decreased. [iwm_tx_credit_inc,
- * called from rx.c:iwm_ntf_tx_credit_update]

- Saying Y here enables TIPC debugging capabilities used by developers.

- Enabling debugging support causes TIPC to display data about its
