Subject: [PATCH 5.4 47/55] drm/i915: re-disable RC6p on Sandy Bridge
Date: Sun, 22 Jan 2023 16:04:34 +0100	[thread overview]
Message-ID: <20230122150224.116522355@linuxfoundation.org> (raw)
In-Reply-To: <20230122150222.210885219@linuxfoundation.org>

From: Sasa Dragic <sasa.dragic@gmail.com>

commit 67b0b4ed259e425b7eed09da75b42c80682ca003 upstream.

RC6p on Sandy Bridge got re-enabled over time, causing visual glitches
and GPU hangs.

Disabled originally in commit 1c8ecf80fdee ("drm/i915: do not enable
RC6p on Sandy Bridge").
