--- Comment #6 from Niklas Haas bugs.freedesktop@haasn.xyz --- Concerning my issue, which I now believe is unrelated, I tracked it down to this commit in libdrm:
a02900133b32dd4a7d6da4966f455ab337e80dfc is the first bad commit commit a02900133b32dd4a7d6da4966f455ab337e80dfc Author: Emil Velikov emil.velikov@collabora.com Date: Tue May 15 17:29:44 2018 +0100
xf86drm: introduce a get_real_pci_path() helper
Introduce a helper which gets the real sysfs path for the given pci device.
In other words, instead opening the /sys/dev/char/*/device symlink, we opt for the actual /sys/devices/pci*/*/
It folds three (nearly identical) snprintf's and paves the way of adding extra devices (see next patch) a piece of pie.
v2: use a caller (on stack) provided real_path (Eric)
