Using the GPU with a VRAM Carveout is a security vulnerability. Nevertheless it is sometimes required, especially when no IOMMU implementation is available for a certain platform. Signed-off-by:

The crash was caused by locking an uninitialized lock during init of drm_gem_object.

nr_rings is reset to 1, but when this function is called for a second (and third!) time nr_rings > 1 is false, thus the else case is entered to set up a buffer for the RPTR shadow and consequently written to RB_RPTR_ADDR, hanging platforms without WHERE_AM_I firmware support. Restructure the condition in such a way that shadow buffer setup only ever happens when has_whereami is true; otherwise preemption is only finalized when the number of ring buffers has not been reset to 1 yet.

When using gem with vram carveout the page allocation is managed via drm_mm. The necessary drm_mm_node is allocated in add_vma, but it is referenced in msm_gem_object as well. It is freed before the drm_mm_node has been deallocated leading to use-after-free on every single vram allocation. Currently put_iova is called before put_pages in both msm_gem_free_object and msm_gem_purge: put_iova -> del_vma -> kfree(vma) // vma holds drm_mm_node /* later */ put_pages -> put_pages_vram -> drm_mm_remove_node( msm_obj->vram_node) // vram_node is a ref to // drm_mm_node; in _msm_gem_new It looks like del_vma does nothing else other than freeing the vma object and removing it from it's list, so delaying the deletion should be harmless. This patch splits put_iova in put_iova_spaces and put_iova_vmas, so the vma can be freed after the mm_node has been deallocated with the mm. Note: The breaking commit separated the vma allocation from within msm_gem_object to outside, so the vram_node reference became outside the msm_gem_object allocation, and freeing order was therefore overlooked.

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. Signed-off-by:

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.

Add a new iommu domain attribute DOMAIN_ATTR_IO_PGTABLE_CFG for pagetable configuration which initially will be used to set quirks like for system cache aka last level cache to be used by client drivers like GPU to set right attributes for caching the hardware pagetables into the system cache and later can be extended to include other page table configuration data.
