Alex Deucher 724c80e1d6 drm/radeon/kms: enable writeback (v2) ... When writeback is enabled, the GPU shadows writes to certain registers into a buffer in memory. The driver can then read the values from the shadow rather than reading back from the register across the bus. Writeback can be disabled by setting the no_wb module param to 1. On r6xx/r7xx/evergreen, the following registers are shadowed: - CP scratch registers - CP read pointer - IH write pointer On r1xx-rr5xx, the following registers are shadowed: - CP scratch registers - CP read pointer v2: - Combine wb patches for r6xx-evergreen and r1xx-r5xx - Writeback is disabled on AGP boards since it tends to be unreliable on AGP using the gart. - Check radeon_wb_init return values properly.
