Subject: [PATCH v8 00/10] DSB enablement.
Date: Fri, 20 Sep 2019 12:26:16 +0530	[thread overview]
Message-ID: <20190920065626.3525-1-animesh.manna@intel.com> (raw)

Display State Buffer (DSB) is hardware capability which allows driver
to batch submit HW programming.

As part of initial enablement common api created which currently used
to program gamma lut proramming.

Going forwad DSB support can be added for HDR and flip related operation.

HSDES: 1209978241
BSpec: 32020

v1: Initial version.

v2: Move intel_dsb files under display folder and fixed an issue.

v3: As per review comments from Chris and Jani,
- removed some unwanted code. (Chris)
- Used i915_gem_object_create_internal instead of _shmem. (Chris)
- cmd_buf_tail removed and can be derived through vma object. (Chris)
- Simplified and optimized code few places. (Chris)
- Called dsb-api directly in callsites instead going via I915_WRITE. (Jani)

v4: Addressed review commnets from Shashank.

v5: Addressed review commnets from Shashank and Jani.

v6: Addressed review commnets from Shashank.

v7: Addressed review commnets from Shashank and Jani.

v8: Addressed review commnets from Shashank and Jani.
