[Intel-gfx] [PATCH 2/2] drm/i915: preserve the PBC bits of TRANS_CHICKEN2

2013-04-08 Thread Paulo Zanoni
From: Paulo Zanoni Bits 30 and 24:0 are PBC, so don't zero them. Some of the other bits are being zeroed, but I couldn't find a reason for this, so leave them as they are for now to avoid regressions. Signed-off-by: Paulo Zanoni --- drivers/gpu/drm/i915/i915_reg.h |8 ++-- drivers/gpu/
