[Mesa-dev] [PATCH v4 0/3] egl/android: Add DRM node probing and filtering

[Robert Foss]

This series replaces the dependency on
GRALLOC_MODULE_PERFORM_GET_DRM_FD with DRM node
probing and disables the support for drm_gralloc.

The series has been tested on Qemu+AOSP, where a
virtio gpu was successfully probed for and
opened.

The current branch can be found here:
https://gitlab.collabora.com/robertfoss/mesa/tree/drm_probing_v4

Changes since v3:
 - Reduced number of probing return codes
 - Simplified driver vendor check in droid_probe_device()
 - Fixed type with ';' prepended to a if-statement
 - Removed a strlen call
 - Switched a sprintf to snprintf
 - Replaced fd == -1 check with < 0
 - Simplified switch+goto statements

Changes since v2:
 - Fixed whitespace issue
 - Diversified return codes from probing functions
 - Switched away from using drmGetDevices2, to iterating over
   /dev/dir/renderD nodes manually

Changes since v1:
 - Added fix for build issue
 - Do not rely on libdrm for probing
 - Distinguish between errors and when no drm devices are found

Changes since RFC:
 - Rebased work on the libdrm patch [2].
 - Included patch from Rob Herring disabling drm_gralloc/flink
   support by default.
 - Added device handler driver probing.
