+1.7 What is memory spread ?
+---------------------------
+There are two boolean flag files per cpuset that control where the
+kernel allocates pages for the file system buffers and related in
+kernel data structures. They are called 'memory_spread_page' and
+'memory_spread_slab'.
+
+If the per-cpuset boolean flag file 'memory_spread_page' is set, then
+the kernel will spread the file system buffers (page cache) evenly
+over all the nodes that the faulting task is allowed to use, instead
+of preferring to put those pages on the node where the task is running.
+
+If the per-cpuset boolean flag file 'memory_spread_slab' is set,
+then the kernel will spread some file system related slab caches,
+such as for inodes and dentries evenly over all the nodes that the
+faulting task is allowed to use, instead of preferring to put those
+pages on the node where the task is running.
+
+The setting of these flags does not affect anonymous data segment or
+stack segment pages of a task.
+
+By default, both kinds of memory spreading are off, and memory
+pages are allocated on the node local to where the task is running,
+except perhaps as modified by the tasks NUMA mempolicy or cpuset
+configuration, so long as sufficient free memory pages are available.
+
+When new cpusets are created, they inherit the memory spread settings
+of their parent.
+
+Setting memory spreading causes allocations for the affected page
+or slab caches to ignore the tasks NUMA mempolicy and be spread
+instead. Tasks using mbind() or set_mempolicy() calls to set NUMA
+mempolicies will not notice any change in these calls as a result of
+their containing tasks memory spread settings. If memory spreading
+is turned off, then the currently specified NUMA mempolicy once again
+applies to memory page allocations.
+
+Both 'memory_spread_page' and 'memory_spread_slab' are boolean flag
+files. By default they contain "0", meaning that the feature is off
+for that cpuset. If a "1" is written to that file, then that turns
+the named feature on.
+
+The implementation is simple.
+
+Setting the flag 'memory_spread_page' turns on a per-process flag
+PF_SPREAD_PAGE for each task that is in that cpuset or subsequently
+joins that cpuset. The page allocation calls for the page cache
+is modified to perform an inline check for this PF_SPREAD_PAGE task
+flag, and if set, a call to a new routine cpuset_mem_spread_node()
+returns the node to prefer for the allocation.
+
+Similarly, setting 'memory_spread_cache' turns on the flag
+PF_SPREAD_SLAB, and appropriately marked slab caches will allocate
+pages from the node returned by cpuset_mem_spread_node().
+
+The cpuset_mem_spread_node() routine is also simple. It uses the
+value of a per-task rotor cpuset_mem_spread_rotor to select the next
+node in the current tasks mems_allowed to prefer for the allocation.
+
+This memory placement policy is also known (in other contexts) as
+round-robin or interleave.
+
+This policy can provide substantial improvements for jobs that need
+to place thread local data on the corresponding node, but that need
+to access large file system data sets that need to be spread across
+the several nodes in the jobs cpuset in order to fit. Without this
+policy, especially for jobs that might have one thread reading in the
+data set, the memory allocation across the nodes in the jobs cpuset
+can become very uneven.
+

+1.8 How do I use cpusets ?
--------------------------
In order to minimize the impact of cpusets on critical kernel
---------------------------
+What: remove EXPORT_SYMBOL(kernel_thread)
+When: August 2006
+Files: arch/*/kernel/*_ksyms.c
+Why: kernel_thread is a low-level implementation detail. Drivers should
+ use the <linux/kthread.h> API instead which shields them from
+ implementation details and provides a higherlevel interface that
+ prevents bugs and code duplication
+Who: Christoph Hellwig <hch@lst.de>
+
+---------------------------
+
What: EXPORT_SYMBOL(lookup_hash)
When: January 2006
Why: Too low-level interface. Use lookup_one_len or lookup_create instead.
---------------------------
+What: Usage of invalid timevals in setitimer
+When: March 2007
+Why: POSIX requires to validate timevals in the setitimer call. This
+ was never done by Linux. The invalid (e.g. negative timevals) were
+ silently converted to more or less random timeouts and intervals.
+ Until the removal a per boot limited number of warnings is printed
+ and the timevals are sanitized.
+
+Who: Thomas Gleixner <tglx@linutronix.de>
+
+---------------------------
+
What: I2C interface of the it87 driver
When: January 2007
Why: The ISA interface is faster and should be always available. The I2C
---------------------------
+What: remove EXPORT_SYMBOL(tasklist_lock)
+When: August 2006
+Files: kernel/fork.c
+Why: tasklist_lock protects the kernel internal task list. Modules have
+ no business looking at it, and all instances in drivers have been due
+ to use of too-lowlevel APIs. Having this symbol exported prevents
+ moving to more scalable locking schemes for the task list.

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...
struct address_space_operations
-------------------------------
This describes how the VFS can manipulate mapping of a file to page cache in
-your filesystem. As of kernel 2.6.13, the following members are defined:
+your filesystem. As of kernel 2.6.16, the following members are defined:
struct address_space_operations {
int (*writepage)(struct page *page, struct writeback_control *wbc);
loff_t offset, unsigned long nr_segs);
struct page* (*get_xip_page)(struct address_space *, sector_t,
int);
+ /* migrate the contents of a page to the specified target */
+ int (*migratepage) (struct page *, struct page *);
};
- writepage: called by the VM write a dirty page to backing store.
+ writepage: called by the VM to write a dirty page to backing store.
+ This may happen for data integrity reasons (i.e. 'sync'), or
+ to free up memory (flush). The difference can be seen in
+ wbc->sync_mode.
+ The PG_Dirty flag has been cleared and PageLocked is true.
+ 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.
+ The page will be Locked when readpage is called, and should be
+ unlocked and marked uptodate once the read completes.
+ If ->readpage discovers that it needs to unlock the page for
+ 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.
+ This function is optional and is called only for pages with
+ PG_Writeback set while waiting for the writeback to complete.
+
writepages: called by the VM to write out pages associated with the
- address_space object.
+ address_space object. If wbc->sync_mode is WBC_SYNC_ALL, then
+ the writeback_control will specify a range of pages that must be
+ written out. If it is WBC_SYNC_NONE, then a nr_to_write is given
+ 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
+ mapped page gets modified.
+ If defined, it should set the PageDirty flag, and the
+ PAGECACHE_TAG_DIRTY tag in the radix tree.
readpages: called by the VM to read pages associated with the address_space
- object.
+ object. This is essentially just a vector version of
+ readpage. Instead of just one page, several pages are
+ requested.
+ readpages is only used for read-ahead, so read errors are
+ ignored. If anything goes wrong, feel free to give up.
prepare_write: called by the generic write path in VM to set up a write
- request for a page.
-
- commit_write: called by the generic write path in VM to write page to
- its backing store.
+ request for a page. This indicates to the address space that
+ the given range of bytes is about to be written. The
+ address_space should check that the write will be able to
+ complete, by allocating space if necessary and doing any other
+ internal housekeeping. If the write will update parts of
+ 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: 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.
bmap: called by the VFS to map a logical block offset within object to
- physical block number. This method is use by for the legacy FIBMAP
- ioctl. Other uses are discouraged.
-
- 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.
-
- direct_IO: called by the VM for direct I/O writes and reads.
+ 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: 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.
+
+ 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.

You can specify multiple console= options on the kernel command line.
You will need to create a new device to use /dev/console. The official
/dev/console is now character device 5,1.
+(You can also use a network device as a console. See

Here's an example that will use /dev/ttyS1 (COM2) as the console.

MODULE_PARMS definitions
------------------------
-MODULE_PARM(defaultorder, "i");
+module_param(defaultorder, ulong, 0);
defaultorder=N
where N is a value from 1 to 12
The buffer order determines the size of the dma buffer for the driver.
rather than 64k as some of the games work more responsively.
(2^N) * PAGE_SIZE = allocated buffer size
-MODULE_PARM(cs_debuglevel, "i");
-MODULE_PARM(cs_debugmask, "i");
+module_param(cs_debuglevel, ulong, 0644);
+module_param(cs_debugmask, ulong, 0644);
cs_debuglevel=N
cs_debugmask=0xMMMMMMMM
where N is a value from 0 (no debug printfs), to 9 (maximum)
0xMMMMMMMM is a debug mask corresponding to the CS_xxx bits (see driver source).
-MODULE_PARM(hercules_egpio_disable, "i");
+module_param(hercules_egpio_disable, ulong, 0);
hercules_egpio_disable=N
where N is a 0 (enable egpio), or a 1 (disable egpio support)
-MODULE_PARM(initdelay, "i");
+module_param(initdelay, ulong, 0);
initdelay=N
This value is used to determine the millescond delay during the initialization
code prior to powering up the PLL. On laptops this value can be used to
properly delay the required time. Also, if the system is booted under AC power
and then the power removed, the mdelay()/udelay() functions will not delay properly.
-MODULE_PARM(powerdown, "i");
+module_param(powerdown, ulong, 0);
powerdown=N
where N is 0 (disable any powerdown of the internal blocks) or 1 (enable powerdown)
-MODULE_PARM(external_amp, "i");
+module_param(external_amp, bool, 0);
external_amp=1
if N is set to 1, then force enabling the EAPD support in the primary AC97 codec.
override the detection logic and force the external amp bit in the AC97 0x26 register
to be reset (0). EAPD should be 0 for powerup, and 1 for powerdown. The VTB Santa Cruz
card has inverted logic, so there is a special function for these cards.
-MODULE_PARM(thinkpad, "i");
+module_param(thinkpad, bool, 0);
thinkpad=1
if N is set to 1, then force enabling the clkrun functionality.
Currently, when the part is being used, then clkrun is disabled for the entire system,

1999-12-08 Dave Forrest, written with kernel version 2.2.12 in mind
CONFIG_PNP_PARPORT M for autoprobe.o IEEE1284 readback module
CONFIG_PRINTER_READBACK M for parport_probe.o IEEE1284 readback module
CONFIG_VIDEO_DEV M for videodev.o video4linux module
- CONFIG_VIDEO_CQCAM M for c-qcam.o Color Quickcam module
+ CONFIG_VIDEO_CQCAM M for c-qcam.o Color Quickcam module
With these flags, the kernel should compile and install the modules.
To record and monitor the compilation, I use:
(make zlilo ; \
make modules; \
- make modules_install ;
+ make modules_install ;
depmod -a ) &>log &
less log # then a capital 'F' to watch the progress
-
+
But that is my personal preference.
2.2 Configuration
-
+
The configuration requires module configuration and device
configuration. I like kmod or kerneld process with the
/etc/modprobe.conf file so the modules can automatically load/unload as
these procedures.
-2.1 Module Configuration
+2.1 Module Configuration
Using modules requires a bit of work to install and pass the
parameters. Understand that entries in /etc/modprobe.conf of:
(CONFIG_PRINTER), the IEEE 1284 system,(CONFIG_PRINTER_READBACK), you
should be able to read some identification from your quickcam with
- modprobe -v parport
- modprobe -v parport_probe
- cat /proc/parport/PORTNUMBER/autoprobe
+ modprobe -v parport
+ modprobe -v parport_probe
+ cat /proc/parport/PORTNUMBER/autoprobe
Returns:
CLASS:MEDIA;
MODEL:Color QuickCam 2.0;
and well. A common problem is that the current driver does not
reliably detect a c-qcam, even though one is attached. In this case,
- modprobe -v c-qcam
+ modprobe -v c-qcam
or
insmod -v c-qcam
3.1 Checklist:
Can you get an image?
- v4lgrab >qcam.ppm ; wc qcam.ppm ; xv qcam.ppm
+ v4lgrab >qcam.ppm ; wc qcam.ppm ; xv qcam.ppm
- Is a working c-qcam connected to the port?

Does the camera work with alternate programs? cqcam, etc?
isn't, you might try patching the c-qcam module to add a parport=xxx
option as in the bw-qcam module so you can specify the parallel port:
- insmod -v c-qcam parport=0
+ insmod -v c-qcam parport=0
And bypass the detection code, see ../../drivers/char/c-qcam.c and
look for the 'qc_detect' code and call.

- The memory of some S3 cards is not recognized right:
-
+
First of all, if you are not using XFree-3.2 or newer, upgrade AT LEAST to
XFree-3.2A! This solved the problem for most people.
(mostly with Trio 64 but also with some others)
Get the free demo version of Accelerated X from www.xinside.com and try
bttv with it. bttv seems to work with most S3 cards with Accelerated X.
-
+
Since I do not know much (better make that almost nothing) about VGA card
programming I do not know the reason for this.
Looks like XFree does something different when setting up the video memory?
- Maybe somebody can enlighten me?
- Would be nice if somebody could get this to work with XFree since
- Accelerated X costs more than some of the grabber cards ...

Better linear frame buffer support for S3 cards will probably be in
XFree 4.0.
-
+
- Grabbing is not switched off when changing consoles with XFree.
That's because XFree and some AcceleratedX versions do not send unmap
events.
- Some popup windows (e.g. of the window manager) are not refreshed.

Disable backing store by starting X with the option "-bs"

It happens that this device will be linked to two times, once from

Does any other model using the w9966 interface chip exist ?
Todo:
-
+
*Add a working EPP mode, since DMA ECP read isn't implemented
in the parport drivers. (That's why it's so sloow)
*Probably some bugs that I don't know of
Please support me by sending feedback!

Changes:
-
+
Alan Cox: Removed RGB mode for kernel merge, added THIS_MODULE
and owner support for newer module locks

+ * SECTION: the internal buffer
+ */
+
+/*
+ * The internal buffer is meant to store obaque blobs of data, so it does
+ * not know of higher level concepts like triggers.
+ * It consists of a number of pages that are used as a ringbuffer. Each data
+ * blob is stored in a simple record that consists of an integer, which
+ * contains the size of the following data, and the data bytes themselfes.
+ *
+ * To allow for multiple independent readers we create one internal buffer
+ * each time the device is opened and destroy the buffer when the file is
+ * closed again. The number of pages used for this buffer is determined by
+ * the module parmeter eer_pages.
+ *
+ * One record can be written to a buffer by using the functions
+ * - dasd_eer_start_record (one time per record to write the size to the
+ * buffer and reserve the space for the data)
+ * - dasd_eer_write_buffer (one or more times per record to write the data)
+ * The data can be written in several steps but you will have to compute
+ * the total size up front for the invocation of dasd_eer_start_record.
+ * If the ringbuffer is full, dasd_eer_start_record will remove the required
+ * number of old records.
+ *
+ * A record is typically read in two steps, first read the integer that
+ * specifies the size of the following data, then read the data.
+ * Both can be done by
+ * - dasd_eer_read_buffer
+ *
+ * For all mentioned functions you need to get the bufferlock first and keep
+ * it until a complete record is written or read.
+ *
+ * All information necessary to keep track of an internal buffer is kept in
+ * a struct eerbuffer. The buffer specific to a file pointer is strored in
+ * the private_data field of that file. To be able to write data to all
+ * existing buffers, each buffer is also added to the bufferlist.
+ * If the user does not want to read a complete record in one go, we have to
+ * keep track of the rest of the record. residual stores the number of bytes
+ * that are still to deliver. If the rest of the record is invalidated between
+ * two reads then residual will be set to -1 so that the next read will fail.
+ * All entries in the eerbuffer structure are protected with the bufferlock.
+ * To avoid races between writing to a buffer on the one side and creating
+ * and destroying buffers on the other side, the bufferlock must also be used
+ * to protect the bufferlist.

+ * DASD_EER_PPRCSUSPEND: PPRC was suspended

+ *
+ * To avoid memory allocations at runtime, the necessary memory is allocated
+ * when the extended error reporting is enabled for a device (by
+ * dasd_eer_probe). There is one sense subsystem status request for each
+ * eer enabled DASD device. The presence of the cqr in device->eer_cqr

+/* 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.

+ The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+ (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+ 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
