Subject: [Intel-gfx] [PATCH 05/11] drm/i915/display/dp: Compute VRR state in atomic_check
Date: Thu, 22 Oct 2020 15:27:03 -0700	[thread overview]
Message-ID: <20201022222709.29386-6-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20201022222709.29386-1-manasi.d.navare@intel.com>

This forces a complete modeset if vrr drm crtc state goes
from enabled to disabled and vice versa.
This patch also computes vrr state variables from the mode timings
and based on the vrr property set by userspace as well as hardware's
vrr capability.

v2:
*Rebase
v3:
* Vmin = max (vtotal, vmin) (Manasi)
v4:
* set crtc_state->vrr.enable = 0 for disable request
