Subject: [PATCH 3/3] drm/vram-helper: Don't put new BOs into VRAM
Date: Tue, 22 Sep 2020 16:57:00 +0200 [thread overview]
Message-ID: <20200922145700.25413-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20200922145700.25413-1-tzimmermann@suse.de>
Most drivers that use VRAM helpers have only a few MiB of framebuffer
memory available. To reduce fragmentation, new BOs are now put into
system memory by default. Only pin operations are allowed to move BOs
into VRAM.
v2:
* rebased onto latest drm-tip
