In some chips, MDP3 has the ability to utilize two pipelines to
parallelly process a single frame.
To enable this feature, multiple CMDQ clients and packets need to
be configured at the same time.

The amount of MDP3 driver probes is determined by the registered

Since MT8195 MDP3 utilizes VPPSYS0 and VPPSYS1, it's necessary to

Instead of walking the entire parent node for something that has the
right compatible, use the scp_get() function provided by the MediaTek
SCP remoteproc driver to retrieve a handle to mtk_scp through the
devicetree "mediatek,scp" (phandle) property.
In case of multi-core SCP, this also allows to select a specific core.

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.

mtk_jpeg_dec_device_run
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.

This patch reverts commit c677d7ae8314
("media: mtk-jpeg: Fix use after free bug due to uncanceled work").
The job_timeout_work is initialized only for
the single-core JPEG device so it will cause the crash for multi-core
JPEG devices.
Fix it by removing the cancel_delayed_work_sync function.

encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.

Pull media updates from Mauro Carvalho Chehab:
- new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913
- new Intel IVSC MEI drivers
- some Mediatek platform drivers were moved to a common location
- Intel atomisp2 driver is now working with the main ov2680 driver. Due
to that, the atomisp2 ov2680 staging one was removed
- the bttv driver was finally converted to videobuf2 framework. This
was the last one upstream using videobuf version 1 core. We'll likely
remove the old videobuf framework on 6.7
- lots of improvements at atomisp driver: it now works with normal I2C
sensors. Several compile-mode dependecies to select between ISP2400
and ISP2401 are now solved in runtime
- a new ipu-bridge logic was added to work with IVSC MEI drivers
- venus driver gained better support for new VPU versions
- the v4l core async framework has gained lots of improvements and
cleanups
- lots of other cleanups, improvements and driver fixes

variable *nplanes is provided by user via system call argument. The
possible value of q_data->fmt->num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.
Fix this bug by checking *nplanes against the array size.
