Subject: drm/i915/tgl: allow the reg_read ioctl to read the RCS TIMESTAMP register
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2b92a82fe03bd426a90b82d69fe1c340ac6b9d74;p=linux.git

drm/i915/tgl: allow the reg_read ioctl to read the RCS TIMESTAMP register

This enables the Mesa driver to advertise support for ARB_timer_query,
and thus an OpenGL version higher than 3.2.

Based on the ICL patch by Paulo Zanoni and CNL patch by Nanley Chery.
