2020-07-21drm/ttm: remove TTM_MEMTYPE_FLAG_CMAChristian König1-1/+0
The original intention was to avoid CPU page table unmaps when BOs move between the GTT and SYSTEM domain.

Support huge (PMD-size and PUD-size) page-table entries by providing a huge_fault() callback. We still support private mappings and write-notify by splitting the huge page-table entries on write-access. Note that for huge page-faults to occur, either the kernel needs to be compiled with trans-huge-pages always enabled, or the kernel needs to be compiled with trans-huge-pages enabled using madvise, and the user-space app needs to call madvise() to enable trans-huge pages on a per-mapping basis. Furthermore huge page-faults will not succeed unless buffer objects and user-space addresses are aligned on huge page size boundaries.

2019-11-28Merge branch 'vmwgfx-coherent' of git://people.freedesktop.org/~thomash/linux into drm-nextDave Airlie1-0/+14
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%.

2019-08-02drm/ttm: Add release_notify callback to ttm_bo_driverFelix Kuehling1-0/+10
This notifies the driver that a BO is about to be released. Releasing a BO also invokes the move_notify callback from ttm_bo_cleanup_memtype_use, but that happens too late for anything that would add fences to the BO and require a delayed delete.

2019-06-18drm/ttm: TTM fault handler helpersThomas Hellstrom1-0/+10
With the vmwgfx dirty tracking, the default TTM fault handler is not completely sufficient (vmwgfx need to modify the vma->vm_flags member, and also needs to restrict the number of prefaults). We also want to replicate the new ttm_bo_vm_reserve() functionality So start turning the TTM vm code into helpers: ttm_bo_vm_fault_reserved() and ttm_bo_vm_reserve(), and provide a default TTM fault handler for other drivers to use.

2019-06-18drm/ttm: Allow the driver to provide the ttm struct vm_operations_structThomas Hellstrom1-0/+6
Add a pointer to the struct vm_operations_struct in the bo_device, and assign that pointer to the default value currently used. The driver can then optionally modify that pointer and the new value can be used for each new vma created.

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.

2019-04-19drm/ttm: fix re-init of global structuresChristian König1-1/+0
When a driver unloads without unloading TTM we don't correctly clear the global structures leading to errors on re-init. Next step should probably be to remove the global structures and kobjs all together, but this is tricky since we need to maintain backward compatibility.
