2020-02-26drm/ttm: fix leaking fences via ttm_buffer_object_transferAhzo1-0/+1
Set the drm_device to NULL, so that the newly created buffer object doesn't appear to use the embedded gem object. This is necessary, because otherwise no corresponding dma_resv_fini for the dma_resv_init is called, resulting in a memory leak. The dma_resv_fini in ttm_bo_release_list is only called if the embedded gem object is not used, which is determined by checking if the drm_device is NULL.

2020-01-16mm, drm/ttm: Fix vm page protection handlingThomas Hellstrom1-7/+15
TTM graphics buffer objects may, transparently to user-space, move between IO and system memory. When that happens, all PTEs pointing to the old location are zapped before the move and then faulted in again if needed. When that happens, the page protection caching mode- and encryption bits may change and be different from those of struct vm_area_struct::vm_page_prot. We were using an ugly hack to set the page protection correctly. Fix that and instead export and use vmf_insert_mixed_prot() or use vmf_insert_pfn_prot(). Also get the default page protection from struct vm_area_struct::vm_page_prot rather than using vm_get_page_prot(). This way we catch modifications done by the vm system for drivers that want write-notification.

git://people.freedesktop.org/~thomash/linux into drm-next Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver to provide coherent graphics memory, meaning that the GPU sees any content written to the coherent memory on the next GPU operation that touches that memory, and the CPU sees any content written by the GPU to that memory immediately after any fence object trailing the GPU operation is signaled. Paravirtual drivers that otherwise require explicit synchronization needs to do this by hooking up dirty tracking to pagefault handlers and buffer object validation. Provide mm helpers needed for this and that also allow for huge pmd- and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7). The code has been tested and exercised by a tailored version of mesa where we disable all explicit synchronization and assume graphics memory is coherent. The performance loss varies of course; a typical number is around 5%.

2019-10-29drm/gem: Fix mmap fake offset handling for drm_gem_object_funcs.mmapRob Herring1-0/+7
Commit c40069cb7bd6 ("drm: add mmap() to drm_gem_object_funcs") introduced a GEM object mmap() hook which is expected to subtract the fake offset from vm_pgoff. However, for mmap() on dmabufs, there is not a fake offset. To fix this, let's always call mmap() object callback with an offset of 0, and leave it up to drm_gem_mmap_obj() to remove the fake offset. TTM still needs the fake offset, so we have to add it back until that's fixed.

2019-10-14drm/ttm: Restore ttm prefaultingThomas Hellstrom1-9/+7
Commit 4daa4fba3a38 ("gpu: drm: ttm: Adding new return type vm_fault_t") broke TTM prefaulting. Since vmf_insert_mixed() typically always returns VM_FAULT_NOPAGE, prefaulting stops after the second PTE. Restore (almost) the original behaviour. Unfortunately we can no longer with the new vm_fault_t return type determine whether a prefaulting PTE insertion hit an already populated PTE, and terminate the insertion loop. Instead we continue with the pre-determined number of prefaults.
