[Intel-gfx] [PATCH 1/5] drm/i915: Add hw.pipe_mode to allow bigjoiner pipe/transcoder split
Manasi Navare
manasi.d.navare at intel.com
Tue Oct 27 19:30:30 UTC 2020
From: Maarten Lankhorst <maarten.lankhorst at linux.intel.com>
With bigjoiner, there will be 2 pipes driving 2 halfs of 1 transcoder,
because of this, we need a pipe_mode for various calculations, including
for example watermarks, plane clipping, etc.
v6:
* renaming in separate function, only pipe_mode here (Ville)
* Add description (Maarten)
v5:
* Rebase (Manasi)
v4:
* Manual rebase (Manasi)
v3:
* Change state to crtc_state, fix rebase err (Manasi)
v2:
* Manual Rebase (Manasi)
