From 468c6816b502614f6d5881af220f34baf72cd285 Mon Sep 17 00:00:00 2001 From: "Michael H. Nguyen" Date: Thu, 13 Nov 2014 17:51:49 +0000 Subject: [PATCH] drm/i915/skl: Add Gen9 LRC size The LRC increased in size on gen9. Make sure we return the right size in get_lr_context_size() v2. Corrected the size, should be 22 pages. I unintentionally mailed out a test patch w/ size equaling 23 pages. Reviewed-by: Damien Lespiau Signed-off-by: Michael H.
