On ChromeOS devices, readdir() processes the directory in the following order:
-NAME- -TYPE- . n/a .. n/a vgem n/a card1 DRM_BUS_PLATFORM renderD129 DRM_BUS_PLATFORM card0 DRM_BUS_PCI renderD128 DRM_BUS_PCI controlD64 DRM_BUS_PCI
In drmGetDevices2, after drmProcessPlatformDevice fails for /dev/dri/card1, we don't process the remaining directory entries. As such, Vulkan fails to initialize since Mesa uses drmGetDevices2. To fix this, continue if drmProcessPlatformDevice fails. --- xf86drm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
