[RESEND PATCH v2 0/5] drm/msm: support for host-cached BOs

From: Jonathan Marek
Date: Sat Nov 14 2020 - 10:21:05 EST


v2:
- added patches 2/3 to enable using dma_ops_bypass
- changed DRM_MSM_GEM_SYNC_CACHE patch to use dma_sync_sg_for_device()
and dma_sync_sg_for_cpu(), and renamed sync flags.

Not sure I did the right thing with for the dma_ops_bypass part,
this is what I came up with reading the emails.

Jonathan Marek (5):
drm/msm: add MSM_BO_CACHED_COHERENT
dma-direct: add dma_direct_bypass() to force direct ops
drm/msm: call dma_direct_bypass()
drm/msm: add DRM_MSM_GEM_SYNC_CACHE for non-coherent cache maintenance
drm/msm: bump up the uapi version
