Subject: [Intel-gfx] [PATCH 13/56] drm/i915/xelpd: Add XE_LPD power wells
Date: Thu, 11 Mar 2021 14:35:49 -0800 [thread overview]
Message-ID: <20210311223632.3191939-14-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210311223632.3191939-1-matthew.d.roper@intel.com>
Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and
A-D. These power wells should be enabled/disabled according to the
following dependency tree (enable top to bottom, disable bottom to top):
PG0
|
--PG1--
/ \
PGA --PG2--
/ | \
PGB PGC PGD
PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the
bits that would have been PG 6-9 under the old scheme.
PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same
as TGL, but DDI-D is placed at index 7 (bits 14 & 15).
