From 0e87d2b06cb4651c874d0b208d31c73addbd638b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 7 Sep 2010 22:11:15 +0200 Subject: [PATCH] intel-gtt: initialize our own scratch page The intel gtt fake agp driver is the only agp driver to use dma address remapping. So it makes sense to fold this code back into the only user (and thus reduce the reliance on the agp code). This patch does the first step by initializing (and remapping) the scratch page in a new function intel_gtt_setup_scratch_page. Unfortunately intel_gtt_cleanup had to move to avoid a forward declaration. The new scratch page is not yet used, though. v2: Refactor out scratch page teardown. Suggested by Chris Wilson on irc. This makes it clear what's going on and results in a nice symmetry between setup and teardown. Signed-off-by: Daniel Vetter Signed-off-by: Chris Wilson --- Reading git-format-patch failed
