[PATCH 14/34] drm/amd/display: Support long vblank feature
Alex Hung
alex.hung at amd.com
Wed Feb 28 18:39:20 UTC 2024
From: Robin Chen <robin.chen at amd.com>
[WHY]
We want to support low hz case, but the original
vtotal/vtotal_min/vtotal_max can't support more
than 0x7FFF.
[HOW]
We use the 2 HW reg to contorl long vblank case.
1. OTG_V_COUNT_STOP_CONTROL -> vcount_stop
2. OTG_V_COUNT_STOP_CONTROL2 -> vcount_stop_timer
vcount_stop define from which line we stop using vcount
and start using vcount2.
vcount_stop_timer define how long we use vcount2.
Ex:
Vtotal = 7
OTG_V_COUNT_STOP_CONTROL = 4
OTG_V_COUNT_STOP_CONTROL2 = 5
time : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
vcount : 0, 1, 2, 3, - - - - - 4, 5, 6
vcount2 : 0, 1, 2, 3, 4,
