2021-07-08drm/gud: Use scatter-gather USB bulk transferNoralf Trønnes
There'a limit to how big a kmalloc buffer can be, and as memory gets fragmented it becomes more difficult to get big buffers. The downside of smaller buffers is that the driver has to split the transfer up which hampers performance. Compression might also take a hit because of the splitting. Solve this by allocating the transfer buffer using vmalloc and create a SG table to be passed on to the USB subsystem. vmalloc_32() is used to avoid DMA bounce buffers on USB controllers that can only access 32-bit addresses. This also solves the problem that split transfers can give host side tearing since flushing is decoupled from rendering. usb_sg_wait() doesn't have timeout handling builtin, so it is wrapped in a timer like 4 out of 6 users in the kernel have done. v2: - Use DIV_ROUND_UP (Linus) - Add timeout note to the commit log (Linus) - Expand note about upper buffer limit (Linus) - Change var name s/timer/ctx/ in gud_usb_bulk_timeout() Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210701170748.58009-2-noralf@tronnes.org
2021-07-08drm/gud: Free buffers on device removalNoralf Trønnes
Free transfer and compression buffers on device removal instead of at DRM device removal time. This ensures that the usual 2x8MB buffers are released when the device is unplugged and not kept around should userspace keep the DRM device fd open. At least Ubuntu 20.04 doesn't release the DRM device on unplug. The damage_lock mutex is not destroyed because it is used outside the drm_dev_enter/exit block in gud_pipe_update(). AFAICT it's possible for an open fbdev descriptor to trigger a commit after the USB device is gone. v2: Don't destroy damage_lock Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210701170748.58009-1-noralf@tronnes.org

2021-07-08drm/i915/adl_s: Fix dma_mask_size to 39 bitTejas Upadhyay
46 bit addressing enables you to use 4 bits to support some MKTME features, and 3 more bits for Optane support that uses a subset of MTKME for persistent memory. But GTT addressing sticking to 39 bit addressing, thus setting dma_mask_size to 39 fixes below tests : igt@i915_selftest@live@mman igt@kms_big_fb@linear-32bpp-rotate-0 igt@gem_create@create-clear igt@gem_mmap_offset@clear igt@gem_mmap_gtt@cpuset-big-copy In a way solves Gitlab#3142 https://gitlab.freedesktop.org/drm/intel/-/issues/3142, which had following errors : DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 7effff9000 [fault reason 05] PTE Write access is not set 0x7effff9000 is suspiciously exactly 39 bits, so it seems likely that the HW just ends up masking off those extra bits hence DMA errors.

2021-07-08drm/i915/gvt: Clear d3_entered on elsp cmd submission.Colin Xu
d3_entered flag is used to mark for vgpu_reset a previous power transition from D3->D0, typically for VM resume from S3, so that gvt could skip PPGTT invalidation in current vgpu_reset during resuming. In case S0ix exit, although there is D3->D0, guest driver continue to use vgpu as normal, with d3_entered set, until next shutdown/reboot or power transition. If a reboot follows a S0ix exit, device power state transite as: D0->D3->D0->D0(reboot), while system power state transites as: S0->S0 (reboot). There is no vgpu_reset until D0(reboot), thus d3_entered won't be cleared, the vgpu_reset will skip PPGTT invalidation however those PPGTT entries are no longer valid. Err appears like: gvt: vgpu 2: vfio_pin_pages failed for gfn 0xxxxx, ret -22 gvt: vgpu 2: fail: spt xxxx guest entry 0xxxxx type 2 gvt: vgpu 2: fail: shadow page xxxx guest entry 0xxxxx type 2. Give gvt a chance to clear d3_entered on elsp cmd submission so that the states before & after S0ix enter/exit are consistent.

2021-07-01nouveau/svm: implement atomic SVM accessAlistair Popple
Some NVIDIA GPUs do not support direct atomic access to system memory via PCIe. Instead this must be emulated by granting the GPU exclusive access to the memory. This is achieved by replacing CPU page table entries with special swap entries that fault on userspace access. The driver then grants the GPU permission to update the page undergoing atomic access via the GPU page tables. When CPU access to the page is required a CPU fault is raised which calls into the device driver via MMU notifiers to revoke the atomic access. The original page table entries are then restored allowing CPU access to proceed.

2021-07-01mm: rename migrate_pgmap_ownerAlistair Popple
MMU notifier ranges have a migrate_pgmap_owner field which is used by drivers to store a pointer. This is subsequently used by the driver callback to filter MMU_NOTIFY_MIGRATE events. Other notifier event types can also benefit from this filtering, so rename the 'migrate_pgmap_owner' field to 'owner' and create a new notifier initialisation function to initialise this field.
