From: Alex Deucher Date: Tue, 9 Apr 2013 16:45:26 +0000 (-0400) Subject: drm/radeon: add support for MC/VM setup on CIK (v6) X-Git-Tag: firefly_0821_release~176^2~5752^2~60^2~158 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1c49165d0abaad5ae4d506635d836e495d5bce43;p=firefly-linux-kernel-4.4.55.git drm/radeon: add support for MC/VM setup on CIK (v6) The vm callbacks are the same as the SI ones right now (same regs and bits). We could share the SI variants, and I may yet do that, but I figured I would add CIK specific ones for now in case we need to change anything. V2: add documentation, minor fixes. V3: integrate vram offset fixes for APUs V4: enable 2 level VM PTs V5: index SH_MEM_* regs properly V6: add ib_parse() Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/radeon/cik.c
