Dave Airlie	1e6e87a3c9	crocus: Make iris_bo_import_dmabuf take a modifier ... Port 493298528a from iris Replace the tiling parameter with a modifier parameter. I find it more straightforward to have this function figure out the tiling from the modifier than to have its caller do it.

Dave Airlie	4cd0f8535c	crocus: Don't call SET_TILING for dmabuf imports ... This is a port of c111e9099c from iris to crocus. Calling SET_TILING on a DMA buffer with the gen12 CCS modifier can fail unnecessarily. The main surface in the BO is Y-tiled, but the CCS portion is linear and can have a stride that's not a multiple of 128B. Because SET_TILING is called on the CCS plane with I915_TILING_Y, the ioctl will sometimes reject the stride. SET_TILING was originally used in b6d45e7f74 to fix an assertion failure in iris_resource_from_handle. Assigning the BO's tiling_mode field is sufficient to avoid the failure.

Dave Airlie	f3630548f1	crocus: initial gallium driver for Intel gfx 4-7 ... This is a gallium driver for the Intel gfx 4-7 GPUs. It was initially cloned from the iris driver by Ilia Mirkin, then I ported over large reams of code from i965 until it worked.
