The Address Space Object
========================
-The address space object is used to identify pages in the page cache.
+The address space object is used to group and manage pages in the page
+cache. It can be used to keep track of the pages in a file (or
+anything else) and also track the mapping of sections of the file into
+process address spaces.
+There are a number of distinct yet related services that an
+address-space can provide. These include communicating memory
+pressure, page lookup by address, and keeping track of pages tagged as
+Dirty or Writeback.
+
+The first can be used independently to the others. The VM can try to
+either write dirty pages in order to clean them, or release clean
+pages in order to reuse them. To do this it can call the ->writepage
+method on dirty pages, and ->releasepage on clean pages with
+PagePrivate set. Clean pages without PagePrivate and with no external
+references will be released without notice being given to the
+address_space.
+
+To achieve this functionality, pages need to be placed on an LRU with
+lru_cache_add and mark_page_active needs to be called whenever the
+page is used.
+
+Pages are normally kept in a radix tree index by ->index. This tree
+maintains information about the PG_Dirty and PG_Writeback status of
+each page, so that pages with either of these flags can be found
+quickly.
+
+The Dirty tag is primarily used by mpage_writepages - the default
+->writepages method. It uses the tag to find dirty pages to call
+->writepage on. If mpage_writepages is not used (i.e. the address
+provides its own ->writepages) , the PAGECACHE_TAG_DIRTY tag is
+almost unused. write_inode_now and sync_inode do use it (through
+__sync_single_inode) to check if ->writepages has been successful in
+writing out the whole address_space.
+
+The Writeback tag is used by filemap*wait* and sync_page* functions,
+via wait_on_page_writeback_range, to wait for all writeback to
+complete. While waiting ->sync_page (if defined) will be called on
+each page that is found to require writeback.
+
+An address_space handler may attach extra information to a page,
+typically using the 'private' field in the 'struct page'. If such
+information is attached, the PG_Private flag should be set. This will
+cause various VM routines to make extra calls into the address_space
+handler to deal with that data.
+
+An address space acts as an intermediate between storage and
+application. Data is read into the address space a whole page at a
+time, and provided to the application either by copying of the page,
+or by memory-mapping the page.
+Data is written into the address space by the application, and then
+written-back to storage typically in whole pages, however the
+address_space has finer control of write sizes.
+
+The read process essentially only requires 'readpage'. The write
+process is more complicated and uses prepare_write/commit_write or
+set_page_dirty to write data into the address_space, and writepage,
+sync_page, and writepages to writeback data to storage.
+
+Adding and removing pages to/from an address_space is protected by the
+inode's i_mutex.
+
+When data is written to a page, the PG_Dirty flag should be set. It
+typically remains set until writepage asks for it to be written. This
+should clear PG_Dirty and set PG_Writeback. It can be actually
+written at any point after PG_Dirty is clear. Once it is known to be
+safe, PG_Writeback is cleared.
+
+Writeback makes use of a writeback_control structure...

+ writepage should start writeout, should set PG_Writeback,
+ and should make sure the page is unlocked, either synchronously
+ or asynchronously when the write operation completes.
+
+ If wbc->sync_mode is WB_SYNC_NONE, ->writepage doesn't have to
+ try too hard if there are problems, and may choose to write out
+ other pages from the mapping if that is easier (e.g. due to
+ internal dependencies). If it chooses not to start writeout, it
+ should return AOP_WRITEPAGE_ACTIVATE so that the VM will not keep
+ calling ->writepage on that page.
+
+ See the file "Locking" for more details.
readpage: called by the VM to read a page from backing store.

+ some reason, it can do so, and then return AOP_TRUNCATED_PAGE.
+ In this case, the page will be relocated, relocked and if
+ that all succeeds, ->readpage will be called again.
sync_page: called by the VM to notify the backing store to perform all
queued I/O operations for a page. I/O operations for other pages
associated with this address_space object may also be performed.

+ and that many pages should be written if possible.
+ If no ->writepages is given, then mpage_writepages is used
+ instead. This will choose pages from the address space that are
+ tagged as DIRTY and will pass them to ->writepage.
set_page_dirty: called by the VM to set a page dirty.
+ This is particularly needed if an address space attaches
+ private data to a page, and that data needs to be updated when
+ a page is dirtied. This is called, for example, when a memory

+ any basic-blocks on storage, then those blocks should be
+ pre-read (if they haven't been read already) so that the
+ updated blocks can be written out properly.
+ The page will be locked. If prepare_write wants to unlock the
+ page it, like readpage, may do so and return
+ AOP_TRUNCATED_PAGE.
+ In this case the prepare_write will be retried one the lock is
+ regained.
- commit_write: called by the generic write path in VM to write page to

+ commit_write: If prepare_write succeeds, new data will be copied
+ into the page and then commit_write will be called. It will
+ typically update the size of the file (if appropriate) and
+ mark the inode as dirty, and do any other related housekeeping
+ operations. It should avoid returning an error if possible -
+ errors should have been handled by prepare_write.

+ physical block number. This method is used by the FIBMAP
+ ioctl and for working with swap-files. To be able to swap to
+ a file, the file must have a stable mapping to a block
+ device. The swap system does not go through the filesystem
+ but instead uses bmap to find out where the blocks in the file
+ are and uses those addresses directly.
- invalidatepage: called by the VM on truncate to disassociate a page from its
- address_space mapping.
- releasepage: called by the VFS to release filesystem specific metadata from
- a page.
+ invalidatepage: If a page has PagePrivate set, then invalidatepage
+ will be called when part or all of the page is to be removed
+ from the address space. This generally corresponds to either a
+ truncation or a complete invalidation of the address space
+ (in the latter case 'offset' will always be 0).
+ Any private data associated with the page should be updated
+ to reflect this truncation. If offset is 0, then
+ the private data should be released, because the page
+ must be able to be completely discarded. This may be done by
+ calling the ->releasepage function, but in this case the
+ release MUST succeed.
- direct_IO: called by the VM for direct I/O writes and reads.
+ releasepage: releasepage is called on PagePrivate pages to indicate
+ that the page should be freed if possible. ->releasepage
+ should remove any private data from the page and clear the
+ PagePrivate flag. It may also remove the page from the
+ address_space. If this fails for some reason, it may indicate
+ failure with a 0 return value.
+ This is used in two distinct though related cases. The first
+ is when the VM finds a clean page with no active users and
+ wants to make it a free page. If ->releasepage succeeds, the
+ page will be removed from the address_space and become free.
+
+ The second case if when a request has been made to invalidate
+ some or all pages in an address_space. This can happen
+ through the fadvice(POSIX_FADV_DONTNEED) system call or by the
+ filesystem explicitly requesting it as nfs and 9fs do (when
+ they believe the cache may be out of date with storage) by
+ calling invalidate_inode_pages2().
+ If the filesystem makes such a call, and needs to be certain
+ that all pages are invalidated, then its releasepage will
+ need to ensure this. Possibly it can clear the PageUptodate
+ bit if it cannot free private data yet.
+
+ direct_IO: called by the generic read/write routines to perform
+ direct_IO - that is IO requests which bypass the page cache
+ and transfer data directly between the storage and the
+ application's address space.
get_xip_page: called by the VM to translate a block number to a page.
The page is valid until the corresponding filesystem is unmounted.
Filesystems that want to use execute-in-place (XIP) need to implement
it. An example implementation can be found in fs/ext2/xip.c.
+ migrate_page: This is used to compact the physical memory usage.
+ If the VM wants to relocate a page (maybe off a memory card
+ that is signalling imminent failure) it will pass a new page
+ and an old page to this function. migrate_page should
+ transfer any private data across and update any references
+ that it has to the page.

+--- 3.11 $(CC) support functions
+
+ The kernel may be build with several different versions of
+ $(CC), each supporting a unique set of features and options.
+ kbuild provide basic support to check for valid options for $(CC).
+ $(CC) is useally the gcc compiler, but other alternatives are
+ available.
+
+ as-option
+ as-option is used to check if $(CC) when used to compile
+ assembler (*.S) files supports the given option. An optional
+ second option may be specified if first option are not supported.
+
+ Example:
+ #arch/sh/Makefile
+ cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),)
+
+ In the above example cflags-y will be assinged the the option
+ -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC).
+ The second argument is optional, and if supplied will be used
+ if first argument is not supported.
+
+ cc-option
+ cc-option is used to check if $(CC) support a given option, and not
+ supported to use an optional second option.
+
+ Example:
+ #arch/i386/Makefile
+ cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586)
+
+ In the above example cflags-y will be assigned the option
+ -march=pentium-mmx if supported by $(CC), otherwise -march-i586.
+ The second argument to cc-option is optional, and if omitted
+ cflags-y will be assigned no value if first option is not supported.
+
+ cc-option-yn
+ cc-option-yn is used to check if gcc supports a given option
+ and return 'y' if supported, otherwise 'n'.
+
+ Example:
+ #arch/ppc/Makefile
+ biarch := $(call cc-option-yn, -m32)
+ aflags-$(biarch) += -a32
+ cflags-$(biarch) += -m32
+
+ In the above example $(biarch) is set to y if $(CC) supports the -m32
+ option. When $(biarch) equals to y the expanded variables $(aflags-y)
+ and $(cflags-y) will be assigned the values -a32 and -m32.
+
+ cc-option-align
+ gcc version >= 3.0 shifted type of options used to speify
+ alignment of functions, loops etc. $(cc-option-align) whrn used
+ as prefix to the align options will select the right prefix:
+ gcc < 3.00
+ cc-option-align = -malign
+ gcc >= 3.00
+ cc-option-align = -falign
+
+ Example:
+ CFLAGS += $(cc-option-align)-functions=4
+
+ In the above example the option -falign-functions=4 is used for
+ gcc >= 3.00. For gcc < 3.00 -malign-functions=4 is used.
+
+ cc-version
+ cc-version return a numerical version of the $(CC) compiler version.
+ The format is <major><minor> where both are two digits. So for example
+ gcc 3.41 would return 0341.
+ cc-version is useful when a specific $(CC) version is faulty in one
+ area, for example the -mregparm=3 were broken in some gcc version
+ even though the option was accepted by gcc.
+
+ Example:
+ #arch/i386/Makefile
+ cflags-y += $(shell \
+ if [ $(call cc-version) -ge 0300 ] ; then \
+ echo "-mregparm=3"; fi ;)
+
+ In the above example -mregparm=3 is only used for gcc version greater
+ than or equal to gcc 3.0.
+
+ cc-ifversion
+ cc-ifversion test the version of $(CC) and equals last argument if
+ version expression is true.
+
+ Example:
+ #fs/reiserfs/Makefile
+ EXTRA_CFLAGS := $(call cc-ifversion, -lt, 0402, -O1)
+
+ In this example EXTRA_CFLAGS will be assigned the value -O1 if the
+ $(CC) version is less than 4.2.
+ cc-ifversion takes all the shell operators:
+ -eq, -ne, -lt, -le, -gt, and -ge

+--- 7.1 Symbols fron the kernel (vmlinux + modules)
+
+ During a kernel build a file named Module.symvers will be generated.
+ Module.symvers contains all exported symbols from the kernel and
+ compiled modules. For each symbols the corresponding CRC value
+ is stored too.
+
+ The syntax of the Module.symvers file is:
+ <CRC> <Symbol> <module>
+ Sample:
+ 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod
+
+ For a kernel build without CONFIG_MODVERSIONING enabled the crc
+ would read: 0x00000000
+
+ Module.symvers serve two purposes.
+ 1) It list all exported symbols both from vmlinux and all modules
+ 2) It list CRC if CONFIG_MODVERSION is enabled
+
+--- 7.2 Symbols and external modules
+
+ When building an external module the build system needs access to
+ the symbols from the kernel to check if all external symbols are
+ defined. This is done in the MODPOST step and to obtain all
+ symbols modpost reads Module.symvers from the kernel.
+ If a Module.symvers file is present in the directory where
+ the external module is being build this file will be read too.
+ During the MODPOST step a new Module.symvers file will be written
+ containing all exported symbols that was not defined in the kernel.
+
+--- 7.3 Symbols from another external module
+
+ Sometimes one external module uses exported symbols from another
+ external module. Kbuild needs to have full knowledge on all symbols
+ to avoid spitting out warnings about undefined symbols.
+ Two solutions exist to let kbuild know all symbols of more than
+ one external module.
+ The method with a top-level kbuild file is recommended but may be
+ impractical in certain situations.
+
+ Use a top-level Kbuild file
+ If you have two modules: 'foo', 'bar' and 'foo' needs symbols
+ from 'bar' then one can use a common top-level kbuild file so
+ both modules are compiled in same build.
+
+ Consider following directory layout:
+ ./foo/ <= contains the foo module
+ ./bar/ <= contains the bar module
+ The top-level Kbuild file would then look like:
+
+ #./Kbuild: (this file may also be named Makefile)
+ obj-y := foo/ bar/
+
+ Executing:
+ make -C $KDIR M=`pwd`
+
+ will then do the expected and compile both modules with full
+ knowledge on symbols from both modules.
+
+ Use an extra Module.symvers file
+ When an external module is build a Module.symvers file is
+ generated containing all exported symbols which are not
+ defined in the kernel.
+ To get access to symbols from module 'bar' one can copy the
+ Module.symvers file from the compilation of the 'bar' module
+ to the directory where the 'foo' module is build.
+ During the module build kbuild will read the Module.symvers
+ file in the directory of the external module and when the
+ build is finished a new Module.symvers file is created
+ containing the sum of all symbols defined and not part of the
+ kernel.

-/* This tables contains entries for the 675/680/690 (Timon) camera, with
- 4 different qualities (no compression, low, medium, high).
- It lists the bandwidth requirements for said mode by its alternate interface
- number. An alternate of 0 means that the mode is unavailable.
-
- There are 6 * 4 * 4 entries:
- 6 different resolutions subqcif, qsif, qcif, sif, cif, vga
- 6 framerates: 5, 10, 15, 20, 25, 30
- 4 compression modi: none, low, medium, high
-
- When an uncompressed mode is not available, the next available compressed mode
- will be chosen (unless the decompressor is absent). Sometimes there are only
- 1 or 2 compressed modes available; in that case entries are duplicated.

+ * NFS client per-mount statistics provide information about the health of

+ * are not for detailed problem diagnosis, but simply to indicate that there
+ * is a problem.
+ *
+ * These counters are not meant to be human-readable, but are meant to be
+ * integrated into system monitoring tools such as "sar" and "iostat". As
+ * such, the counters are sampled by the tools over time, and are never
+ * zeroed after a file system is mounted. Moving averages can be computed
+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.

+ * 3. DIRECT - the number of bytes read or written from files opened

+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.
+ *
+ * The counters are maintained in a single array per RPC client, indexed

+/* msp3400 routing
+ ===============
+
+ The msp3400 has a complicated routing scheme with many possible
+ combinations. The details are all in the datasheets but I will try
+ to give a short description here.
+
+ Inputs
+ ======
+
+ There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+ to select which tuner input to use and which SCART input to use. The
+ selected tuner input, the selected SCART input and all I2S inputs go to
+ the DSP (the tuner input first goes through the demodulator).
+
+ The DSP handles things like volume, bass/treble, balance, and some chips
+ have support for surround sound. It has several outputs: MAIN, AUX, I2S
+ and SCART1/2. Each output can select which DSP input to use. So the MAIN
+ output can select the tuner input while at the same time the SCART1 output
+ uses the I2S input.
+
+ Outputs
+ =======
+
+ Most DSP outputs are also the outputs of the msp3400. However, the SCART
+ outputs of the msp3400 can select which input to use: either the SCART1 or
+ SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+ bypassing the DSP.
+
+ Summary
+ =======
+
+ So to specify a complete routing scheme for the msp3400 you will have to
+ specify in the 'input' field of the v4l2_routing struct:
+
+ 1) which tuner input to use
+ 2) which SCART input to use
+ 3) which DSP input to use for each DSP output
+
+ And in the 'output' field of the v4l2_routing struct you specify:
+
+ 1) which SCART input to use for each SCART output
+
+ Depending on how the msp is wired to the other components you can
+ ignore or mute certain inputs or outputs.
+
+ Also, depending on the msp version only a subset of the inputs or
+ outputs may be present. At the end of this header some tables are
+ added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+ 1) the tuner (SIF) input
+ 2) the SCART input
+ Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+ input, bits 4-7 are reserved.

+ There also is a quasi-peak detector output, but that is not used by
+ this driver and is set to the same input as the loudspeaker output.
+ Not all outputs are supported by all msp models. Setting the input
+ of an unsupported output will be ignored by the driver.
+
+ There are up to 16 DSP inputs to choose from, so each output is
+ assigned 4 bits.
+
+ Note: the 44x8G can mix two inputs and feed the result back to the
+ DSP. This is currently not implemented. Also not implemented is the
