Subject: kcm_opengl: Fix retrieval of DRI information
|
||||
|
||||
Summary:
|
||||
Currently DRI information retrieval is attempted via /proc/dri, which
|
||||
was removed from the linux kernel in v3.12 (2013). This information
|
||||
includes the kernel driver in use as well as card identification sourced
|
||||
from pci.ids database.
|
||||
|
||||
This adds support for retrieving this information in the same vein via
|
||||
/dev and /sys for modern kernels.
|
||||
|
||||
Test Plan: kcmshell5 opengl should correctly display kernel driver.
