Compared to SDM8450 DPU devices with active CTL support (SC7180, SM8x50)
have merge support implemented in a separate hardware block, which is
not supported at this point. Add support for dualpipe configuration on
these platforms. Tested on Qualcomm RB5 (SM8250) platform.

Instead of calling 4 callbacks to set pending masks, call just one to
update both pending_flush_mask and pending_intf_flush mask. Note, that
CMD mode support incorrectly did not update pending_intf_flush mask,
breaking CMD support on SC7180/SM8x50.

Add initial support for merge3D hardware block on SM8[12]50. Merge3D is
reposible for merging contents of two LMs (two PPs) into single
interface.

* [PATCH 2/5] drm/msm/dpu: initial support for merge3D hardware block
@ 2020-10-22 13:16 ` Dmitry Baryshkov

From: Dmitry Baryshkov @ 2020-10-22 13:16 UTC (permalink / raw)
To: Rob Clark, Sean Paul, Jonathan Marek, linux-arm-msm, dri-devel,

Cc: David Airlie
Add initial support for merge3D hardware block on SM8[12]50. Merge3D is
reposible for merging contents of two LMs (two PPs) into single
interface.

Handle new merge_3d block setup in dpu encoder code. Pass correct mode
and id. Note, that merge_3d blocks are not handled via usual RM
reservation mechanism, as each merge_3d block is tied to two PPs, so by
reserving PP you get merge_3d automatically.
