2020-03-24drm/vmwgfx: Support huge page faultsThomas Hellstrom (VMware)1-1/+4
With vmwgfx dirty-tracking we need a specialized huge_fault callback. Implement and hook it up.

2020-01-15drm/vmwgfx: Use VM_PFNMAP instead of VM_MIXEDMAP when possibleThomas Hellstrom1-0/+4
For shared, and read-only private mappings of graphics memory, use VM_PFNMAP instead of VM_MIXEDMAP. This means less accounting overhead when inserting and removing page-table entries. TTM doesn't do this by default, since there was a performance problem with book-keeping of write-combined mappings. Since vmwgfx solely uses cached mappings, that's not a problem and now that the TTM vm has largely been turned into helpers, we can use VM_PFNMAP on a per-driver basis Signed-off-by: Thomas Hellstrom <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
2019-11-06drm/vmwgfx: Implement an infrastructure for write-coherent resourcesThomas Hellstrom1-1/+14
This infrastructure will, for coherent resources, make sure that from the user-space point of view, data written by the CPU is immediately automatically available to the GPU at resource validation time.

2019-03-19drm/ttm: Quick-test mmap offset in ttm_bo_mmap()Thomas Zimmermann1-9/+2
A BO's address has to be at least the minimum offset. Sharing this test in ttm_bo_mmap() removes code from drivers. A full buffer-address validation is still done within drm_vma_offset_lockup_locked().

2019-03-19drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constantThomas Zimmermann1-1/+1
Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same value. The only exception is vboxvideo, which is being converted to the new offset by this patch. Unifying the constants in a single place simplifies the driver code.

2018-12-13drm/vmwgfx: Protect from excessive execbuf kernel memory allocations v3Thomas Hellstrom1-0/+36
With the new validation code, a malicious user-space app could potentially submit command streams with enough buffer-object and resource references in them to have the resulting allocated validion nodes and relocations make the kernel run out of GFP_KERNEL memory. Protect from this by having the validation code reserve TTM graphics memory when allocating.

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA. The driver is under staging the same as Nouveau and Radeon KMS. Hopefully the 2D ioctls are bug free and don't need changing, so that part of the API should be stable. But there there is a pretty big chance that the 3D API will change in the future.
