This refactors code for start/stop streaming vb2 operations and
adds a state machine handling similar to the one in stateful codec
API documentation. One major change is that now the HFI session is
started on STREAMON(OUTPUT) and stopped on REQBUF(OUTPUT,count=0),
during that time STREAMOFF(CAP,OUT) just flush buffers but doesn't
stop the session. The other major change is that now the capture
and output queues are completely separated.

Until now we returned num_output_bufs set during reqbuf but
that could be wrong when we implement stateful Codec API. So
get the minimum buffers for capture from HFI. This is supposed
to be called after stream header parsing, i.e. after dequeue
v4l2 event for change resolution.

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.
As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.
Luckily, perhaps, there were just a handful of callers using the function.

The reason is that the hfi_parser actually expects:
- multiple data entries on hfi_capabilities
- multiple profile_level on hfi_profile_level_supported
However, the structs trick gcc, making it to believe that

Switch all media platform drivers to call v4l2_async_notifier_add_subdev()
to add asd's to a notifier, in place of referencing the notifier->subdevs[]
array. These drivers also must now call v4l2_async_notifier_init() before
adding asd's to their notifiers.
There may still be cases where a platform driver maintains a list of
asd's that is a duplicate of the notifier asd_list, in which case its
possible the platform driver list can be removed, and can reference the
notifier asd_list instead. One example of where a duplicate list has
been removed in this patch is xilinx-vipp.c. If there are such cases
remaining, those drivers should be optimized to remove the duplicate
platform driver asd lists.
None of the changes to the platform drivers in this patch have been
tested. Verify that the async subdevices needed by the platform are
bound at load time, and that the driver unloads and reloads correctly

This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.
Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.
Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).
The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make
V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to
select the desired profile for VP8 encoder and query for supported profiles by
VP8 encoder/decoder.
Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this control cannot be used for querying since
it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.
The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)
In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in

When checking a format for validity, the resolution is reset to 1280x720
whenever the pixel format is not supported. This behavior can mislead
user-space into believing that this is the only resolution supported,
and looks strange considering that if we try/set the same format with
just the pixel format changed to a valid one, the call will this time
succeed without altering the resolution.
Resolution is managed independently of the pixel format, so remove this
reset.

find_format_by_index() stops enumerating formats as soon as the index
matches, and returns NULL if venus_helper_check_codec() finds out that
the format is not supported. This prevents formats to be properly
enumerated if a non-supported format is present, as the enumeration will
end with it.
Fix this by moving the call to venus_helper_check_codec() into the loop,
and keep enumerating when it fails.

The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one
struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME
match criteria requires just a device name.
So, it doesn't make sense to enclose those into structs,
as the criteria can go directly into the union.
That makes easier to document it, as we don't need to document
weird senseless structs.
At drivers, this makes even clearer about the match criteria.

Merge tag 'afs-next-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull AFS updates from David Howells:
"kAFS filesystem driver overhaul.
The major points of the overhaul are:
(1) Preliminary groundwork is laid for supporting network-namespacing
of kAFS. The remainder of the namespacing work requires some way
to pass namespace information to submounts triggered by an
automount. This requires something like the mount overhaul that's
in progress.
(2) sockaddr_rxrpc is used in preference to in_addr for holding
addresses internally and add support for talking to the YFS VL
server. With this, kAFS can do everything over IPv6 as well as
IPv4 if it's talking to servers that support it.
(3) Callback handling is overhauled to be generally passive rather
than active. 'Callbacks' are promises by the server to tell us
about data and metadata changes. Callbacks are now checked when
we next touch an inode rather than actively going and looking for
it where possible.
(4) File access permit caching is overhauled to store the caching
information per-inode rather than per-directory, shared over
subordinate files. Whilst older AFS servers only allow ACLs on
directories (shared to the files in that directory), newer AFS
servers break that restriction.
To improve memory usage and to make it easier to do mass-key
removal, permit combinations are cached and shared.
(5) Cell database management is overhauled to allow lighter locks to
be used and to make cell records autonomous state machines that
look after getting their own DNS records and cleaning themselves
up, in particular preventing races in acquiring and relinquishing
the fscache token for the cell.
(6) Volume caching is overhauled. The afs_vlocation record is got rid
of to simplify things and the superblock is now keyed on the cell
and the numeric volume ID only. The volume record is tied to a
superblock and normal superblock management is used to mediate
the lifetime of the volume fscache token.
(7) File server record caching is overhauled to make server records
independent of cells and volumes. A server can be in multiple
cells (in such a case, the administrator must make sure that the
VL services for all cells correctly reflect the volumes shared
between those cells).
Server records are now indexed using the UUID of the server
rather than the address since a server can have multiple
addresses.
(8) File server rotation is overhauled to handle VMOVED, VBUSY (and
similar), VOFFLINE and VNOVOL indications and to handle rotation
both of servers and addresses of those servers. The rotation will
also wait and retry if the server says it is busy.
(9) Data writeback is overhauled. Each inode no longer stores a list
of modified sections tagged with the key that authorised it in
favour of noting the modified region of a page in page->private
and storing a list of keys that made modifications in the inode.
This simplifies things and allows other keys to be used to
actually write to the server if a key that made a modification
becomes useless.
(10) Writable mmap() is implemented. This allows a kernel to be build
entirely on AFS.
Note that Pre AFS-3.4 servers are no longer supported, though this can
be added back if necessary (AFS-3.4 was released in 1998)"

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The async subdev notifier .bound(), .unbind() and .complete() operations
are function pointers stored directly in the v4l2_async_subdev
structure. As the structure isn't immutable, this creates a potential
security risk as the function pointers are mutable.
To fix this, move the function pointers to a new
v4l2_async_subdev_operations structure that can be made const in

This addresses the wrong behavior of decoder stop command by
rewriting it. These new implementation enqueue an empty buffer
on the decoder input buffer queue to signal end-of-stream. The
client should stop queuing buffers on the V4L2 Output queue
and continue queuing/dequeuing buffers on Capture queue. This
process will continue until the client receives a buffer with

In venus_boot(), we pass a pointer to a phys_addr_t
into dmam_alloc_coherent, which the compiler warns about:
platform/qcom/venus/firmware.c: In function 'venus_boot':
platform/qcom/venus/firmware.c:63:49: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
To avoid the error refactor venus_boot function by discard
dma_alloc_coherent invocation because we don't want to map the
memory for the device. Something more, the usage of
DMA mapping API is actually wrong and the current
implementation relies on several bugs in DMA mapping code.
When these bugs are fixed that will break firmware loading,
so fix this now to avoid future troubles.
The meaning of venus_boot is to copy the content of the
firmware buffer into reserved (and memblock removed)
block of memory and pass that physical address to the
trusted zone for authentication and mapping through iommu
form the secure world. After iommu mapping is done the iova
is passed as ane entry point to the remote processor.
After this change memory-region property is parsed manually
and the physical address is memremap to CPU, call mdt_load to
load firmware segments into proper places and unmap
reserved memory.

The problem is that in the error case, we've incremented the data ptr
but not decremented rem_bytes, and keep reading (presumably garbage)
until eventually we go beyond the end of the buffer.
Instead, on first error, we should probably just bail out. Other
option is to increment read_bytes by sizeof(u32) before the switch,
rather than only accounting for the ptype header in the non-error
case. Note that in this case it is HFI_ERR_SYS_INVALID_PARAMETER,
ie. an unrecognized/unsupported parameter, so interpreting the next
word as a property type would be bogus. The other error cases are
due to truncated buffer, so there isn't likely to be anything valid
to interpret in the remainder of the buffer. So just bailing seems
like a reasonable solution.

This adds Venus driver Makefile and changes v4l2 platform
Makefile/Kconfig in order to enable building of the driver.
Note that in this initial version the COMPILE_TEST-ing is not
supported because the drivers specific to ARM builds are still
in process of enabling the aforementioned compile testing.
Once that disadvantage is fixed the Venus driver compile testing
will be possible with follow-up changes.

Here is the implementation of Venus video accelerator low-level
functionality. It contanins code which setup the registers and
startup uthe processor, allocate and manipulates with the shared
memory used for sending commands and receiving messages.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.
- hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.
- hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.
- hfi_msgs takes care of messages sent from firmware to the
host.

* core.c has implemented the platform driver methods, file
operations and v4l2 registration.
* helpers.c has implemented common helper functions for:
- buffer management
- vb2_ops and functions for format propagation,
- functions for allocating and freeing buffers for
internal usage. The buffer parameters describing internal
buffers depends on current format, resolution and codec.
- functions for calculation of current load of the
hardware. Depending on the count of instances and
resolutions it selects the best clock rate for the video
core.
* firmware loader
