Subject: [Intel-gfx] [PATCH v3 2/3] drm/i915/display: Add function quirk_renderclear_reduced
Date: Sun, 1 Nov 2020 07:42:43 -0700 [thread overview]
Message-ID: <20201101144244.10086-3-rwright@hpe.com> (raw)
In-Reply-To: <20201101144244.10086-1-rwright@hpe.com>
From: Randy Wright <rwright@hpe.com>
Added function quirk_renderclear_reduced to set QUIRK_RENDERCLEAR_REDUCED
for designated platforms. Applying QUIRK_RENDERCLEAR_REDUCED for
the HP Pavilion Mini 300-020 prevents a GPU hang.
