[Intel-gfx] [PATCH i-g-t 0/8] Vendor agnostic gputop

[Kamil Konieczny]

Hi,

please rebase and resend, also please change commit subject to start
with lib: or lib/[name of lib changed]: rest od commit description

For example, in 3/8 instead of
libdrmclients: Record client drm minor
write:
lib/igt_drm_clients: Record client drm minor

If there are more lib changes, use "lib: " alone, for example
in your 2/8 patch,
libdrmfdinfo: Allow specifying custom engine map
write:
lib: Allow specifying custom engine map

+Cc Petri and Zbyszek

Regards,
Kamil
