2023-02-06drm/ttm: prevent moving of pinned BOsChristian König
We have checks for this in the individual drivers move callback, but it's probably better to generally forbid that on a higher level. Also stops exporting ttm_resource_compat() since that's not necessary any more after removing the extra checks in vmwgfx.

2022-07-07drm/nouveau/nouveau_bo: fix potential memory leak in nouveau_bo_alloc()Jianglei Nie
nouveau_bo_alloc() allocates a memory chunk for "nvbo" with kzalloc(). When some error occurs, "nvbo" should be released. But when WARN_ON(pi < 0)) equals true, the function return ERR_PTR without releasing the "nvbo", which will lead to a memory leak. We should release the "nvbo" with kfree() if WARN_ON(pi < 0)) equals true.

2021-10-06drm/nouveau/ga102-: support ttm buffer moves via copy engineBen Skeggs
We don't currently have any kind of real acceleration on Ampere GPUs, but the TTM memcpy() fallback paths aren't really designed to handle copies between different devices, such as on Optimus systems, and result in a kernel OOPS. A few options were investigated to try and fix this, but didn't work out, and likely would have resulted in a very unpleasant experience for users anyway. This commit adds just enough support for setting up a single channel connected to a copy engine, which the kernel can use to accelerate the buffer copies between devices. Userspace has no access to this incomplete channel support, but it's suitable for TTM's needs. A more complete implementation of host(fifo) for Ampere GPUs is in the works, but the required changes are far too invasive that they would be unsuitable to backport to fix this issue on current kernels. v2: fix GPFIFO length in RAMFC (reported by Karol) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: Lyude Paul <lyude@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Cc: <stable@vger.kernel.org> # v5.12+ Reviewed-by: Karol Herbst <kherbst@redhat.com> Tested-by: Karol Herbst <kherbst@redhat.com> Signed-off-by: Karol Herbst <kherbst@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210916220406.666454-1-skeggsb@gmail.com Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. The GEM object function is provided by GEM TTM helpers.

Pull drm updates from Dave Airlie: "Not a huge amount of big things here, AMD has support for a few new HW variants (vangogh, green sardine, dimgrey cavefish), Intel has some more DG1 enablement.

2020-12-14drm/ttm: cleanup BO size handling v3Christian König
Based on an idea from Dave, but cleaned up a bit. We had multiple fields for essentially the same thing. Now bo->base.size is the original size of the BO in arbitrary units, usually bytes. bo->mem.num_pages is the size in number of pages in the resource domain of bo->mem.mem_type. v2: use the GEM object size instead of the BO size v3: fix printks in some places Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> (v1) Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/406831/
