Hey all,
I am trying to test Jagan's patch series [1] to add support for the
samsung dsim bridge which is used on the imx8mm to output DSI video.
The DSIM gets the video from the mxsfb, and in my case, the DSI is
sent to the adv7535 for connecting to HDMI.
I have been able to get the device tree

The reproducer does this:
ioctl(3, TIOCLINUX, TIOCL_SETSEL, selection: xs
The line and column numbers for the selection need to start at 1.
Add the checks to prevent invalid input.

When changing the console font with ioctl(KDFONTOP) the new font size
can be bigger than the previous font. A previous selection may thus now
be outside of the new screen size and thus trigger out-of-bounds
accesses to graphics memory if the selection is removed in
vc_do_resize().

Hi Thomas,
I cannot drop the older DRI1 based uAPI calls.
This is because include/uapi/drm/via_drm.h needs to retain backward
compatibility with the existing OpenChrome DDX's XvMC library (it gets compiled
when OpenChrome DDX is built) and likely with the existing DDX Xv code as well.

Hi Thomas,
In general, I am okay with the idea of keeping DRI1 based VIA DRM for now.
Personally, I am not that interested in keeping it, but I am not against
keeping it, either.
Coming up with a scheme to keep the DRI1 based VIA DRM is sort of beyond my
skill level, so I am glad you and Sam ca

Hi Sam,
I will study vc4_drm.h and update newer portions (i.e., the section I am
actively adding to via_drm.h) with new comments that can be converted to
kernel-doc automatically.
I also plan to rework the uAPI somewhat.

Recently, I debugged a few device crashes which occured during recovery
after a hangcheck timeout. It looks like there are a few things we can
do to improve our chance at a successful gpu recovery.
First one is to ensure that CX GDSC collapses which clears the internal
states in gpu's CX domain.
Instead of separate refcount for each submit, take single rpm refcount
on behalf of all the submits. This makes it easier to drop the rpm
refcount during recovery in an upcoming patch.

There are some hardware logic under CX domain. For a successful
recovery, we should ensure cx headswitch collapses to ensure all the
stale states are cleard out. This is especially true to for a6xx family
where we can GMU co-processor.
Currently, cx doesn't collapse due to a devlink between gpu an

Because there could be transient votes from other drivers/tz/hyp which
may keep the cx gdsc enabled, we should poll until cx gdsc collapses.
We can use the reset framework to poll for cx gdsc collapse from gpucc
clk driver.
This feature requires support from the platform's gpucc driver.

Variable ret is assigned a value that is never read; it is either
