soc: mediatek: Prepare MMSYS for DDP routing using function call
by Yongqiang Niu 22 Mar '21

22 Mar '21

The following series are intended to prepare the mtk-mmsys driver to allow different DDP (Data Display Path) function call per SoC. base change: https://patchwork.kernel.org/project/linux-mediatek/patch/20201006193320.40… Change since v2: - fix review issue in v2 - add 8183 mmsys function call - add 8192 new component - add 8192 mmsys function call

[PATCH] RFC: i915: Drop relocation support on Gen12+
by Jason Ekstrand 12 Mar '21

12 Mar '21

The Vulkan driver in Mesa for Intel hardware never uses relocations if it's running on a version of i915 that supports at least softpin which all versions of i915 supporting Gen12 do. On the OpenGL side, Gen12 is only supported by iris which never uses relocations. The older i965 driver in Mesa does use relocations but it only supports Intel hardware through Gen11 and has been deprecated for all hardware Gen9+. The entire relocation UAPI and related infrastructure, therefore, doesn't have any open-source userspace consumer starting with Gen12. Rejecting relocations starting with Gen12 has the benefit that we don't have to bother supporting it on platforms with local memory. Given how much CPU touching of memory is required for relocations, not having to do so on platforms where not all memory is directly CPU-accessible carries significant advantages.

[PATCH v5 0/7] drm: add simpledrm driver
by David Herrmann 12 Mar '21

12 Mar '21

Hey On request of Noralf, I picked up the patches and prepared v5. Works fine with Xorg, if configured according to: https://lists.freedesktop.org/archives/dri-devel/2014-January/052777.html If anyone knows how to make Xorg pick it up dynamically without such a static configuration, please let me know.

[PATCH v2 0/5] drm/panel-simple: Patches for N116BCA-EA1
by Douglas Anderson 11 Mar '21

11 Mar '21

This series is to get the N116BCA-EA1 panel working. Most of the patches are simple, but on hardware I have in front of me the panel sometimes doesn't come up. I'm still working with the hardware manufacturer to get to the bottom of it, but I've got it working with retries. Adding the retries doesn't seem like an insane thing to do and makes some of the error handling more robust, so I've gone ahead and included those patches here. Hopefully they look OK. Changes in v2: - Set the "unprepared_time" so if we retry we give the proper delay. - ("drm/panel-simple: Don't wait longer for HPD...") new for v2. - ("drm/panel-simple: Retry if we timeout waiting for HPD") new for v2. - ("dt-bindings: dt-bindings: display: simple: Add N116BCA-EA1") new for v2. - ("drm/panel-simple: Add N116BCA-EA1") new for v2.

[PATCH 00/35] Add HMM-based SVM memory manager to KFD
by Felix Kuehling 11 Mar '21

11 Mar '21

This is the first version of our HMM based shared virtual memory manager for KFD. There are still a number of known issues that we're working through (see below). This will likely lead to some pretty significant changes in MMU notifier handling and locking on the migration code paths. So don't get hung up on those details yet. But I think this is a good time to start getting feedback. We're pretty confident about the ioctl API, which is both simple and extensible for the future. (see patches 4,16) The user mode side of the API can be found here: https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/blob/fxkamd/hmm-w… I'd also like another pair of eyes on how we're interfacing with the GPU VM code in amdgpu_vm.c (see patches 12,13), retry page fault handling (24,25), and some retry IRQ handling changes (32). Known issues: * won't work with IOMMU enabled, we need to dma_map all pages properly * still working on some race conditions and random bugs * performance is not great yet Alex Sierra (12): drm/amdgpu: replace per_device_list by array drm/amdkfd: helper to convert gpu id and idx drm/amdkfd: add xnack enabled flag to kfd_process drm/amdkfd: add ioctl to configure and query xnack retries drm/amdkfd: invalidate tables on page retry fault drm/amdkfd: page table restore through svm API drm/amdkfd: SVM API call to restore page tables drm/amdkfd: add svm_bo reference for eviction fence drm/amdgpu: add param bit flag to create SVM BOs drm/amdkfd: add svm_bo eviction mechanism support drm/amdgpu: svm bo enable_signal call condition drm/amdgpu: add svm_bo eviction to enable_signal cb Philip Yang (23): drm/amdkfd: select kernel DEVICE_PRIVATE option drm/amdkfd: add svm ioctl API drm/amdkfd: Add SVM API support capability bits drm/amdkfd: register svm range drm/amdkfd: add svm ioctl GET_ATTR op drm/amdgpu: add common HMM get pages function drm/amdkfd: validate svm range system memory drm/amdkfd: register overlap system memory range drm/amdkfd: deregister svm range drm/amdgpu: export vm update mapping interface drm/amdkfd: map svm range to GPUs drm/amdkfd: svm range eviction and restore drm/amdkfd: register HMM device private zone drm/amdkfd: validate vram svm range from TTM drm/amdkfd: support xgmi same hive mapping drm/amdkfd: copy memory through gart table drm/amdkfd: HMM migrate ram to vram drm/amdkfd: HMM migrate vram to ram drm/amdgpu: reserve fence slot to update page table drm/amdgpu: enable retry fault wptr overflow drm/amdkfd: refine migration policy with xnack on drm/amdkfd: add svm range validate timestamp drm/amdkfd: multiple gpu migrate vram to vram drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c | 3 + drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h | 4 +- .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_fence.c | 16 +- .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 13 +- drivers/gpu/drm/amd/amdgpu/amdgpu_mn.c | 83 + drivers/gpu/drm/amd/amdgpu/amdgpu_mn.h | 7 + drivers/gpu/drm/amd/amdgpu/amdgpu_object.h | 5 + drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 90 +- drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c | 47 +- drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h | 10 + drivers/gpu/drm/amd/amdgpu/vega10_ih.c | 32 +- drivers/gpu/drm/amd/amdgpu/vega20_ih.c | 32 +- drivers/gpu/drm/amd/amdkfd/Kconfig | 1 + drivers/gpu/drm/amd/amdkfd/Makefile | 4 +- drivers/gpu/drm/amd/amdkfd/kfd_chardev.c | 170 +- drivers/gpu/drm/amd/amdkfd/kfd_iommu.c | 8 +- drivers/gpu/drm/amd/amdkfd/kfd_migrate.c | 866 ++++++ drivers/gpu/drm/amd/amdkfd/kfd_migrate.h | 59 + drivers/gpu/drm/amd/amdkfd/kfd_priv.h | 52 +- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 200 +- .../amd/amdkfd/kfd_process_queue_manager.c | 6 +- drivers/gpu/drm/amd/amdkfd/kfd_svm.c | 2564 +++++++++++++++++ drivers/gpu/drm/amd/amdkfd/kfd_svm.h | 135 + drivers/gpu/drm/amd/amdkfd/kfd_topology.c | 1 + drivers/gpu/drm/amd/amdkfd/kfd_topology.h | 10 +- include/uapi/linux/kfd_ioctl.h | 169 +- 26 files changed, 4296 insertions(+), 291 deletions(-) create mode 100644 drivers/gpu/drm/amd/amdkfd/kfd_migrate.c create mode 100644 drivers/gpu/drm/amd/amdkfd/kfd_migrate.h create mode 100644 drivers/gpu/drm/amd/amdkfd/kfd_svm.c create mode 100644 drivers/gpu/drm/amd/amdkfd/kfd_svm.h -- 2.29.2
