NULL
The struct v4l2_input::name is an array, so the checking of
(mxc_capture_inputs[cam->current_input].name != NULL) always return
true. The issue was introduced by commit 5b1aeb69cf15 ("media: capture:
add mxc v4l2 capture driver").

[ Upstream commit bfb1b99802ef16045402deb855c197591dc78886 ]
The ipi handler here tries hard to maintain const-ness of its argument,
but by doing that causes a warning about function type casts:
drivers/media/platform/mediatek/vcodec/common/mtk_vcodec_fw_vpu.c:38:32: error: cast from 'mtk_vcodec_ipi_handler' (aka 'void (*)(void *, unsigned int, void *)') to 'ipi_handler_t' (aka 'void (*)(const void *, unsigned int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
38 | ipi_handler_t handler_const = (ipi_handler_t)handler;
| ^~~~~~~~~~~~~~~~~~~~~~
Remove the hack and just use a non-const argument.

[ Upstream commit 794b581f8c6eb7b60fe468ccb96dd3cd38ff779f ]
Currently coefficients are applied only once, since they don't change.
However, this is done before enable bit is set and thus it doesn't get
applied properly.
Fix that by applying coefficients after enable bit is set. While this
means that it will be done evey time, it doesn't bring much time
penalty.

commit a107d643b2a3382e0a2d2c4ef08bf8c6bff4561d upstream.
This reverts commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74.
The rkisp1 does share interrupt lines on some platforms, after all. Thus
we need to revert this, and implement a fix for the rkisp1 shared irq
handling in a follow-up patch.

[ Upstream commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74 ]
In all known platforms the ISP has dedicated IRQ lines, but for some
reason the driver uses IRQF_SHARED.
Supporting IRQF_SHARED properly requires handling interrupts even when
our device is disabled, and the driver does not handle this. To avoid
adding such code, and to be sure the driver won't accidentally be used
in a platform with shared interrupts, let's drop the IRQF_SHARED flag.

[ Upstream commit 9e7dc39260edac180c206bb6149595a40eabae3e ]
When using 32 bit RGB formats, the RGA on the rk3568 produces wrong
colors as the wrong color channels are read or written. The reason is
that the format description for the channel swizzeling is wrong and the
wrong bits are configured. For example, when converting ARGB32 to NV12,
the alpha channel is used as blue channel.. This doesn't happen if the
color format is the same on both sides.
Fix the color_swap settings of the formats to correctly handle 32 bit
RGB formats.
For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an
effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus,
it is removed from the list of supported formats.

mtk_jpeg_dec_device_run
[ Upstream commit 206c857dd17d4d026de85866f1b5f0969f2a109e ]
In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with
mtk_jpeg_job_timeout_work.
In mtk_jpeg_dec_device_run, if error happens in
mtk_jpeg_set_dec_dst, it will finally start the worker while
mark the job as finished by invoking v4l2_m2m_job_finish.
There are two methods to trigger the bug. If we remove the
module, it which will call mtk_jpeg_remove to make cleanup.
The possible sequence is as follows, which will cause a
use-after-free bug.
CPU0 CPU1
mtk_jpeg_dec_... |
start worker |
|mtk_jpeg_job_timeout_work
mtk_jpeg_remove |
v4l2_m2m_release |
kfree(m2m_dev); |
|
| v4l2_m2m_get_curr_priv
| m2m_dev->curr_ctx //use
If we close the file descriptor, which will call mtk_jpeg_release,
it will have a similar sequence.
Fix this bug by starting timeout worker only if started jpegdec worker
successfully. Then v4l2_m2m_job_finish will only be called in
either mtk_jpeg_job_timeout_work or mtk_jpeg_dec_device_run.

[ Upstream commit 87889f1b7ea40d2544b49c62092e6ef2792dced7 ]
In the current driver csid Test Pattern Generator (TPG) doesn't work.
This change:
- fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0
- fixes the shift by one between test_pattern control value and the
actual pattern.
- drops fixed VC of 0x0a which testing showed prohibited some test
patterns in the CSID to produce output.
So that TPG starts working, but with the below limitations:
- only test_pattern=9 works as it should
- test_pattern=8 and test_pattern=7 produce black frame (all zeroes)
- the rest of test_pattern's don't work (yavta doesn't get the data)
- regardless of the CFA pattern set by 'media-ctl -V' the actual pixel
order is always the same (RGGB for any RAW8 or RAW10P format in
4608x2592 resolution).
Tested with:
RAW10P format, VC0:
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4608x2592 field:none]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4608x2592 field:none]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
v4l2-ctl -d /dev/v4l-subdev6 -c test_pattern=9
yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4608x2592 /dev/video0
RAW10P format, VC1:
media-ctl -V '"msm_csid0":2[fmt:SRGGB10/4608x2592 field:none]'

[ Upstream commit 3c4ed72a16bc6733cda9c65048af74a2e8eaa0eb ]
CSID hardware on SM8250 can demux up to 4 simultaneous streams
based on virtual channel (vc) or datatype (dt).
The CSID subdevice entity now has 4 source ports that can be
enabled/disabled and thus can control which virtual channels
are enabled. Datatype demuxing not tested.
In order to keep a valid internal state of the subdevice,
implicit format propagation from the sink to the source pads
has been preserved. However, the format on each source pad
can be different and in that case it must be configured explicitly.
CSID's s_stream is called when any stream is started or stopped.
It will call configure_streams() that will rewrite IRQ settings to HW.
When multiple streams are running simultaneously there is an issue
when writing IRQ settings for one stream while another is still
running, thus avoid re-writing settings if they were not changed
in link setup, or by fully powering off the CSID hardware.

commit 3143ad282fc08bf995ee73e32a9e40c527bf265d upstream.
There are two problems with the current vfe_disable_output() routine.
Firstly we rightly use a spinlock to protect output->gen2.active_num
everywhere except for in the IDLE timeout path of vfe_disable_output().
Even if that is not racy "in practice" somehow it is by happenstance not
by design.
Secondly we do not get consistent behaviour from this routine. On
sc8280xp 50% of the time I get "VFE idle timeout - resetting". In this
case the subsequent capture will succeed. The other 50% of the time, we
don't hit the idle timeout, never do the VFE reset and subsequent
captures stall indefinitely.
Rewrite the vfe_disable_output() routine to
- Quiesce write masters with vfe_wm_stop()
- Set active_num = 0
remembering to hold the spinlock when we do so followed by
- Reset the VFE
Testing on sc8280xp and sdm845 shows this to be a valid fix.

commit 26bda3da00c3edef727a6acb00ed2eb4b22f8723 upstream.
Right now it is possible to do a vfe_get() with the internal reference
count at 1. If vfe_check_clock_rates() returns non-zero then we will
leave the reference count as-is and
run:
- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()
skip:
- camss_disable_clocks()
Subsequent vfe_put() calls will when the ref-count is non-zero
unconditionally run:
- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()
- camss_disable_clocks()
vfe_get() should not attempt to roll-back on error when the ref-count is
non-zero as the upper layers will still do their own vfe_put() operations.
vfe_put() will drop the reference count and do the necessary power
domain release, the cleanup jumps in vfe_get() should only be run when
the ref-count is zero.

commit 7405116519ad70b8c7340359bfac8db8279e7ce4 upstream.
We need to make sure camss_configure_pd() happens before
camss_register_entities() as the vfe_get() path relies on the pointer
provided by camss_configure_pd().
Fix the ordering sequence in probe to ensure the pointers vfe_get() demands
are present by the time camss_register_entities() runs.
In order to facilitate backporting to stable kernels I've moved the
configure_pd() call pretty early on the probe() function so that
irrespective of the existence of the old error handling jump labels this
patch should still apply to -next circa Aug 2023 to v5.13 inclusive.

commit 8d0b89398b7ebc52103e055bf36b60b045f5258f upstream.
The hfi parser, parses the capabilities received from venus firmware and
copies them to core capabilities. Consider below api, for example,
fill_caps - In this api, caps in core structure gets updated with the
number of capabilities received in firmware data payload. If the same api
is called multiple times, there is a possibility of copying beyond the max
allocated size in core caps.
Similar possibilities in fill_raw_fmts and fill_profile_level functions.

commit b18e36dfd6c935da60a971310374f3dfec3c82e1 upstream.
Buffer requirement, for different buffer type, comes from video firmware.
While copying these requirements, there is an OOB possibility when the
payload from firmware is more than expected size. Fix the check to avoid
the OOB possibility.

commit 0768a9dd809ef52440b5df7dce5a1c1c7e97abbd upstream.
Supported codec bitmask is populated from the payload from venus firmware.
There is a possible case when all the bits in the codec bitmask is set. In
such case, core cap for decoder is filled and MAX_CODEC_NUM is utilized.
Now while filling the caps for encoder, it can lead to access the caps
array beyong 32 index. Hence leading to OOB write.
The fix counts the supported encoder and decoder. If the count is more than
max, then it skips accessing the caps.

[ Upstream commit b2701715301a49b53d05c7d43f3fedc3b8743bfc ]
The notifier is added to the global notifier list when registered. When
the module is removed, the struct csi2rx_priv in which the notifier is
embedded, is destroyed. As a result the notifier list has a reference to
a notifier that no longer exists. This causes invalid memory accesses
when the list is iterated over. Similar for when the probe fails.
Unregister and clean up the notifier to avoid this.

supported beyond msm8916 (HFI V1) and some newer HFI versions really

[ Upstream commit 927e78ac8bc58155316cf6f46026e1912bbbbcfc ]
ALIGN() expects its second argument to be a power of 2, otherwise
incorrect results are produced for some inputs. The output can be
both larger or smaller than what is expected.
For example, ALIGN(304, 192) equals 320 instead of 384, and
ALIGN(65, 192) equals 256 instead of 192.
However, nestling two ALIGN() as is done in this case seem to only
produce results equal to or bigger than the expected result if ALIGN()
had handled non powers of two, and that in turn results in framesizes
that are either the correct size or too large.
Fortunately, since 192 * 4 / 3 equals 256, it turns out that one ALIGN()
is sufficient.

[ Upstream commit e10707d5865c90d3dfe4ef589ce02ff4287fef85 ]
When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.
Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

[ Upstream commit e3a69496a1cde364c74a600d7a370179b58aed29 ]
Structures passed to subdev pad operations are all zero-initialized, but
not always with the same kind of code constructs. While most drivers
used designated initializers, which zero all the fields that are not
specified, when declaring variables, some use memset(). Those two
methods lead to the same end result, and, depending on compiler
optimizations, may even be completely equivalent, but they're not
consistent.
Improve coding style consistency by using designated initializers
instead of calling memset(). Where applicable, also move the variables
to inner scopes of for loops to ensure correct initialization in all
iterations.

[ Upstream commit 0e82d3715fd208de567b8e4307fbf91ae5e57db4 ]
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
