2020-09-15gpu/drm: ingenic: Add option to mmap GEM buffers cachedPaul Cercueil
Ingenic SoCs are most notably used in cheap chinese handheld gaming consoles. There, the games and applications generally render in software directly into GEM buffers. Traditionally, GEM buffers are mapped write-combine. Writes to the buffer are accelerated, and reads are slow. Application doing lots of alpha-blending paint inside shadow buffers, which is then memcpy'd into the final GEM buffer. On recent Ingenic SoCs however, it is much faster to have a fully cached GEM buffer, in which applications paint directly, and whose data is invalidated before scanout, than having a write-combine GEM buffer, even when alpha blending is not used. Add an optional 'cached_gem_buffers' parameter to the ingenic-drm driver to allow GEM buffers to be mapped fully-cached, in order to speed up software rendering. v2: Use standard noncoherent DMA APIs v3: Use damage clips instead of invalidating full frames v4: Avoid dma_pgprot() which is not exported. Using vm_get_page_prot() is enough in this case. v5: - Avoid calling drm_gem_cma_prime_mmap(). It has the side effect that an extra object reference is obtained, which causes our dumb buffers to never be freed. It should have been drm_gem_cma_mmap_obj(). However, our custom mmap function only differs with one flag, so we can cleanly handle both modes in ingenic_drm_gem_mmap(). - Call drm_gem_vm_close() if drm_mmap_attrs() failed, just like in drm_gem_cma_mmap_obj().

2020-09-14drm/i915: Drop the drm_atomic_helper_calc_timestamping_constants() callVille Syrjälä
We update the timestamping constants per-crtc explicitly in intel_crtc_update_active_timings(). Furtermore the helper will use uapi.adjusted_mode whereas we want hw.adjusted_mode. Thus let's drop the helper call an rely on what we already have in intel_crtc_update_active_timings(). We can now also drop the hw.adjusted_mode -> uapi.adjusted_mode copy hack that was added to keep the helper from deriving the timestamping constants from the wrong thing.

2020-09-14drm/i915: Fix g4x+ sprite dotclock limit for upscalingVille Syrjälä
Even if we're not doing downscaling we should account for some of the extra dotclock limitations for g4x+ sprites. In particular we must never exceed the 90% rule, and with RGB that limits actually drops to 80%. So instead of bailing out when upscaling let's clamp the scaling factor appropriately and go through the rest of calculation normally. By luck we already did the full calculations for the 1:1 case.

2020-09-12drm/msm: Add private interface for adreno-smmuRob Clark
This interface will be used for drm/msm to coordinate with the qcom_adreno_smmu_impl to enable/disable TTBR0 translation. Once TTBR0 translation is enabled, the GPU's CP (Command Processor) will directly switch TTBR0 pgtables (and do the necessary TLB inv) synchronized to the GPU's operation. But help from the SMMU driver is needed to initially bootstrap TTBR0 translation, which cannot be done from the GPU. Since this is a very special case, a private interface is used to avoid adding highly driver specific things to the public iommu interface.
