[Intel-gfx] [PATCH v2 22/25] drm/i915/gen12: MBUS B credit change

2019-07-08 Thread Lucas De Marchi
From: Rodrigo Vivi Previously, the recommended B credit for all platforms was 24 / number of pipes, which would give 6 for newer platforms with 4 pipes. However 6 is not enough and we need 12 on these cases. We also need a different BW credit for these platforms. Cc: Arthur J Runyan Signed-off
