Change default device permission to 666 Patch libdrm to default to device permission 666 so we don't have to do it in xorg.conf. The only way libdrm can do anything is through the server anyway. This can still be overridden by a user's xorg.conf.
[PATCH] amdgpu: add env support for amdgpu.ids path In some cases, like when building a Snap application that uses libdrm, the `amdgpu.ids` file isn't directly available at the compiling place, but inside a mounted folder. This forces each application to link/bind the file from the current place (usually at the $SNAP/gnome-platform/usr/share/libdrm/amdgpu.ids) which is cumbersome.
This patch allows to set an environment variable, called AMDGPU_ASIC_ID_TABLE_PATH, where the file will be also searched if it isn't located in the default, meson-configured, path.
xf86drm: Handle NULL in drmCopyVersion Just as it is already handled in the caller, `drmGetVersion`.
I'm not sure what the offending driver is, but the Ubuntu incidents seem to be coming from a dual Intel/Nvidia machine. And they show it is `card1` so I'm guessing `nvidia-drm` is the offender.
