Bug ID: 104730
Summary: VLC crashes on playback with "READ_ONLY without WC is
disallowed"
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi

VLC gdb bt
In current git master, vlc crashes on any playback with the above assertion.
This is not happening on the same system with Mesa 17.3.3.
I assume the new assertion comes from the following patch:
https://patchwork.freedesktop.org/patch/191502/
https://cgit.freedesktop.org/mesa/mesa/commit/?id=c7f84f6513f9cc9502b9cf3bdca9b95a6b87c98b

This happens with vaapi and omx with assertions enabled.
My patch
https://lists.freedesktop.org/archives/mesa-dev/2018-January/182646.html works
around that by setting the RADEON_FLAG_GTT_WC for UVD buffers in the first
place. Without the patch and with assertions disabled, this flag ends up being
set anyways.
This might not be the right thing to do though, perhaps some other code around
that needs to be fixed.

This does not seem to have made it into mesa 18.0.0-rc3.
