drm/xe/bmg: Apply Wa_22019338487drm-xe-next-2024-07-02
Extend this WA to BMG GT as well. In this case media GT is not affected. The cap frequencies and max allowed ggtt writes are different as well. On BMG, we need to do a flush after 1100 GGTT writes, and we need to limit the GT frequency request to 2133 Mhz during driver load and leave it at that value after driver unloads. v3: Fix checkpatch issue Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240701231529.2582452-2-vinay.belgaumkar@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
