[Resend v3] drm/msm/disp/dpu1: add safe lut config in dpu driver

by Kalyan Thota

Add safe lut configuration for all the targets in dpu driver as per QOS recommendation. Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly.

[v2] drm/msm/disp/dpu1: add safe lut config in dpu driver

by Kalyan Thota

Add safe lut configuration for all the targets in dpu driver as per QOS recommendation. Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly.

[PATCH v3] lib: Use PFN_PHYS() in devmem_is_allowed()

by Liang Wang

The physical address may exceed 32 bits on 32-bit systems with more than 32 bits of physcial address,use PFN_PHYS() in devmem_is_allowed(), or the physical address may overflow and be truncated. We found this bug when mapping a high addresses through devmem tool, when CONFIG_STRICT_DEVMEM is enabled on the ARM with ARM_LPAE and devmem is used to map a high address that is not in the iomem address range, an unexpected error indicating no permission is returned. This bug was initially introduced from v2.6.37, and the function was moved to lib when v5.11.
