2020-11-29drm/msm/dpu: consider vertical front porch in the prefill bw calculationKalyan Thota
In case of panels with low vertical back porch, the prefill bw requirement will be high as we will have less time(vbp+pw) to fetch and fill the hw latency buffers before start of first line in active period. For ex: Say hw_latency_line_buffers = 24, and if blanking vbp+pw = 10 Here we need to fetch 24 lines of data in 10 line times. This will increase the bw to the ratio of linebuffers to blanking. DPU hw can also fetch data during vertical front porch provided interface prefetch is enabled. Use vfp in the prefill calculation as dpu driver enables prefetch if the blanking is not sufficient to fill the latency lines.

2020-11-29drm/msm/a6xx: Add support for using system cache(LLC)Sharat Masetty
The last level system cache can be partitioned to 32 different slices of which GPU has two slices preallocated. One slice is used for caching GPU buffers and the other slice is used for caching the GPU SMMU pagetables. This talks to the core system cache driver to acquire the slice handles, configure the SCID's to those slices and activates and deactivates the slices upon GPU power collapse and restore. Some support from the IOMMU driver is also needed to make use of the system cache to set the right TCR attributes. GPU then has the ability to override a few cacheability parameters which it does to override write-allocate to write-no-allocate as the GPU hardware does not benefit much from it. DOMAIN_ATTR_IO_PGTABLE_CFG is another domain level attribute used by the IOMMU driver for pagetable configuration which will be used to set a quirk initially to set the right attributes to cache the hardware pagetables into the system cache.
