Setting context source and destination formats should only be done
in hantro_set_fmt_out() and hantro_set_fmt_cap() after check that
the targeted queue is not busy.
Remove these calls from hantro_reset_encoded_fmt() and
hantro_reset_raw_fmt() to clean the driver.

This patch landed recently in linux-next as commit db6f68b51e5c ("media: 
verisilicon: Do not set context src/dst formats in reset functions").

Unfortunately it causes the following regression during Debian boot on 
Odroid-M1 board:

I know that v4l_id tool, which is a part of systemd/udev, is known to 
crash badly on various vendor kernels (fixing this would be a really 
hard, especially assuming the brokenness of some vendor hacks), but I 
hoped that at least it should not be able to crash the mainline kernel.

Hi,

I do not have this board up and running with Hantro encoder but
I think the attached patch may solve the issue.
Could you tell me if it works ?

Benjamin

Yep, it fixes the issue.

It looks that the code could be a bit more cleaned up, as with the 
attached patch, there is such construction:

         if (coded) {
                 pix_mp->num_planes = 1;
                 vpu_fmt = fmt;
         } else if (ctx->is_encoder) {
                 vpu_fmt = fmt;
         } else {
                 vpu_fmt = fmt;
                 /*
                  * Width/height on the CAPTURE end of a decoder are 
ignored and
                  * replaced by the OUTPUT ones.
                  */
                 pix_mp->width = ctx->src_fmt.width;
                 pix_mp->height = ctx->src_fmt.height;
         }

Common 'vpu_fmt = fmt' can be moved out of the above if-else block.

KernelCI found this patch causes a regression in the
baseline.dmesg.alert test [1] on rk3399-rock-pi-4b [2],
see the bisection report for more details [3].

Let us know if you have any questions.

Thx for the report. FWIW, regzbot noticed there is a patch that refers
to the culprit that might have been landed in next after your test ran
for the last time (and meanwhile it was mainlined): f100ce3bbd6 ("media:
verisilicon: Fix crash when probing encoder")

I wonder if that is related or might even fix the issue.

Ciao, Thorsten

Yes that patch should fix the probing issue.
Marek is working on an additional one to fix pixel format negotiation
but that doesn't impact the boot.

Great, thx for the reply.

Shreeya, normally I believe developers in cases like this and would have
included

 #regzbot fix: f100ce3bbd6

in this mail (without the space in front of the #) to mark the
regression as resolved. Would that be okay for you and other kernel.ci
people? Or do you want to confirm this first?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

I checked the commit pointed out and also double checked with Benjamin 
internally so
we are good to mark this as fixed.


#regzbot fix: f100ce3bbd6a
