7a62d444a2 media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)
commit 31e97d7c9ae3de072d7b424b2cf706a03ec10720 upstream.

This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10
driver.  This improves the readability and more importantly, for the
solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13):

 - the preprocessed size from 121 MiB to 4.5 MiB;

 - the build CPU time from 46.8 s to 1.6 s;

 - the build memory from 2786 MiB to 98MiB.

In fine, this allows this relatively simple C file to be built on a
32-bit system.

8a31520642 media: rkisp1: resizer: Stop manual allocation of v4l2_subdev_state
[ Upstream commit efa28efd9cba015f8c3d88123527c3c3cfcd13d0 ]

Supported media bus codes on the resizer sink pad are identical to the
ISP source pad. The .enum_mbus_code() handler thus delegates the
enumeration to the ISP's operation. This is problematic for two
reasons:

- Format enumeration on the ISP source pad is dependent on the format
  configured on the ISP sink pad for the same subdev state (TRY or
  ACTIVE), while format enumeration on the resizer sink pad should
  return all formats supported by the resizer subdev, regardless of the
  ISP configuration.

- Delegating the operation involves creating a fake v4l2_subdev_state on
  the stack to pass to the ISP .enum_mbus_code() handler. This gets in
  the way of evolution of both the ISP enumeration handler and, more
  generally, the V4L2 subdev state infrastructure.

Fix those two issues by implementing format enumeration manually for the
resizer.

fab4834383 media: rkisp1: Fix IRQ disable race issue
[ Upstream commit 870565f063a58576e8a4529f122cac4325c6b395 ]

In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.

This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.

It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

[ Upstream commit 3eb7910e1b16a2c136be26a8380f21469225b2f6 ]

The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.

Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.

[ 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.

8254d54d00 media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run
commit 206c857dd17d4d026de85866f1b5f0969f2a109e upstream.

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.

commit 38e1857933def4b3fafc28cc34ff3bbc84cad2c3 upstream.

In mtk_jpegdec_worker, if error occurs in mtk_jpeg_set_dec_dst, it
will start the timeout worker and invoke v4l2_m2m_job_finish at
the same time. This will break the logic of design for there should
be only one function to call v4l2_m2m_job_finish. But now the timeout
handler and mtk_jpegdec_worker will both invoke it.

Fix it by start the worker only if mtk_jpeg_set_dec_dst successfully
finished.

commit 608ca5a60ee47b48fec210aeb7a795a64eb5dcee upstream.

For dmabuf import users to be able to use the vaddr from another
videobuf2-dma-sg source, the exporter needs to set a proper vaddr on
vb2_dma_sg_dmabuf_ops_vmap callback. This patch adds vmap on map if
buf->vaddr was not set.

commit 47a78052db51b16e8045524fbf33373b58f1323b upstream.

As the sensor device maybe accessible right after its async sub-device is
registered, such as ipu-bridge will try to power up sensor by sensor's
client device's runtime PM from the async notifier callback, if runtime PM
is not enabled, it will fail.

So runtime PM should be ready before its async sub-device is registered
and accessible by others.

It also sets the runtime PM status to active as the sensor was turned
on by i2c-core.

[ Upstream commit fb387fcb5cdd0384ba04a5d15a3605e2dccdab2a ]

The driver always enables the clocks at probe() and disables them only
at remove(). It is not clear why the driver does this, as it supports
runtime PM, and enables and disables the clocks in the runtime resume
and suspend callbacks. Also, in the case runtime PM is not available,
the driver calls the resume and suspend callbacks manually from probe()
and remove().

Drop the unnecessary clock enable, thus enabling the clocks only when
actually needed.

[ Upstream commit 3f1faa154a4316b1b585a25394697504b3c24e98 ]

The old (now removed) videobuf framework had an optional vbi hack where
the sequence number of the frame counter was copied in the last 4 bytes
of the buffer. This hack was active only for the read() interface
(so not for streaming I/O), and it was enabled by bttv. This allowed
applications that used read() for the VBI data to match it with the
corresponding video frame.

When bttv was converted to vb2 this hack was forgotten, but some old
applications rely on this.

So add this back, but this time in the bttv driver rather than in the
vb2 framework.

commit f910d3ba78a2677c23508f225eb047d89eb4b2b6 upstream.

Digging into the documentation we find that the DT_ID bitfield is used to
map the six bit DT to a two bit ID code. This value is concatenated to the
VC bitfield to create a CID value. DT_ID is the two least significant bits
of CID and VC the most significant bits.

Originally we set dt_id = vc * 4 in and then subsequently set dt_id = vc.

commit 3c4ed72a16bc ("media: camss: sm8250: Virtual channels for CSID")
silently fixed the multiplication by four which would give a better
value for the generated CID without mentioning what was being done or why.

Next up I haplessly changed the value back to "dt_id = vc * 4" since there
didn't appear to be any logic behind it.

Hans asked what the change was for and I honestly couldn't remember the
provenance of it, so I dug in.

commit 87889f1b7ea40d2544b49c62092e6ef2792dced7 upstream.

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:

check_clock doesn't account for vfe_lite which means that vfe_lite will

commit 7f24d291350426d40b36dfbe6b3090617cdfd37a upstream.

vfe-480 is copied from vfe-17x and has the same racy idle timeout bug as in
17x.

Fix the vfe_disable_output() logic to no longer be racy and to conform
to the 17x way of quiescing and then resetting the VFE.

b1eaec007b media: qcom: camss: Fix VFE-17x vfe_disable_output()
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.

816a4070bc media: qcom: camss: Fix vfe_get() error jump
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.
