[PATCH v2 1/3] drm/msm/mdp4: convert to drm_crtc_handle_vblank()
by Dmitry Baryshkov 16 Jun '22

16 Jun '22

Stop using deprecated drm_handle_vblank(), use drm_crtc_handle_vblank() instead.

[PATCH v2 0/5] drm/msm: fixes for KMS iommu handling
by Dmitry Baryshkov 16 Jun '22

16 Jun '22

This series started from the applied and then reverted [2] patch by Robin Murphy [1]. After the MDSS rework [3] has landed it is now possible to reapply the extended version of the original patch. While we are at it, also rework the IOMMU init code for DPU and MDP5 drivers. For MDP5 this moves iommu_domain_alloc() call and removes struct mdp5_cfg_platform remains. For DPU this allows specifying the iommus = <...> either in the DPU device (like all DPU devices do) or in the MDSS device (like MDP5 devices do). Changes since v1: - Move aspace init to common helper - Use device_iommu_mapped() rather than semi-internal dev_iommu_fwspec_get() (suggested by Robin Murphy) [1] https://patchwork.freedesktop.org/patch/480707/ [2] https://patchwork.freedesktop.org/patch/482453/ [3] https://patchwork.freedesktop.org/series/98525/ Dmitry Baryshkov (5): drm/msm/dpu: check both DPU and MDSS devices for the IOMMU drm/msm/mdp5: move iommu_domain_alloc() call close to its usage drm/msm: Stop using iommu_present() drm/msm: move KMS aspace init to the separate helper drm/msm: switch msm_kms_init_aspace() to use device_iommu_mapped() drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 24 ++--------- drivers/gpu/drm/msm/disp/mdp5/mdp5_cfg.c | 16 -------- drivers/gpu/drm/msm/disp/mdp5/mdp5_cfg.h | 6 --- drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 31 +++----------- drivers/gpu/drm/msm/msm_drv.c | 51 +++++++++++++++++++++++- drivers/gpu/drm/msm/msm_drv.h | 1 + 6 files changed, 59 insertions(+), 70 deletions(-) -- 2.35.1

[PATCH v7 0/6] Proposal for a GPU cgroup controller
by T.J. Mercier 15 Jun '22

15 Jun '22

This patch series revisits the proposal for a GPU cgroup controller to track and limit memory allocations by various device/allocator subsystems. The patch series also contains a simple prototype to illustrate how Android intends to implement DMA-BUF allocator attribution using the GPU cgroup controller. The prototype does not include resource limit enforcements. Changelog: v7: Hide gpucg and gpucg_bucket struct definitions per Michal Koutný. This means gpucg_register_bucket now returns an internally allocated struct gpucg_bucket. Move all public function documentation to the cgroup_gpu.h header. Remove comment in documentation about duplicate name rejection which is not relevant to cgroups users per Michal Koutný. v6: Move documentation into cgroup-v2.rst per Tejun Heo. Rename BINDER_FD{A}_FLAG_SENDER_NO_NEED -> BINDER_FD{A}_FLAG_XFER_CHARGE per Carlos Llamas. Return error on transfer failure per Carlos Llamas. v5: Rebase on top of v5.18-rc3 Drop the global GPU cgroup "total" (sum of all device totals) portion of the design since there is no currently known use for this per Tejun Heo. Fix commit message which still contained the old name for dma_buf_transfer_charge per Michal Koutný. Remove all GPU cgroup code except what's necessary to support charge transfer from dma_buf. Previously charging was done in export, but for non-Android graphics use-cases this is not ideal since there may be a delay between allocation and export, during which time there is no accounting. Merge dmabuf: Use the GPU cgroup charge/uncharge APIs patch into dmabuf: heaps: export system_heap buffers with GPU cgroup charging as a result of above. Put the charge and uncharge code in the same file (system_heap_allocate, system_heap_dma_buf_release) instead of splitting them between the heap and the dma_buf_release. This avoids asymmetric management of the gpucg charges. Modify the dma_buf_transfer_charge API to accept a task_struct instead of a gpucg. This avoids requiring the caller to manage the refcount of the gpucg upon failure and confusing ownership transfer logic. Support all strings for gpucg_register_bucket instead of just string literals. Enforce globally unique gpucg_bucket names. Constrain gpucg_bucket name lengths to 64 bytes. Append "-heap" to gpucg_bucket names from dmabuf-heaps. Drop patch 7 from the series, which changed the types of binder_transaction_data's sender_pid and sender_euid fields. This was done in another commit here: https://lore.kernel.org/all/20220210021129.3386083-4-masahiroy@kernel.org/ Rename: gpucg_try_charge -> gpucg_charge find_cg_rpool_locked -> cg_rpool_find_locked init_cg_rpool -> cg_rpool_init get_cg_rpool_locked -> cg_rpool_get_locked "gpu cgroup controller" -> "GPU controller" gpucg_device -> gpucg_bucket usage -> size Tests: Support both binder_fd_array_object and binder_fd_object. This is necessary because new versions of Android will use binder_fd_object instead of binder_fd_array_object, and we need to support both. Tests for both binder_fd_array_object and binder_fd_object. For binder_utils return error codes instead of struct binder{fs}_ctx. Use ifdef __ANDROID__ to choose platform-dependent temp path instead of a runtime fallback. Ensure binderfs_mntpt ends with a trailing '/' character instead of prepending it where used. v4: Skip test if not run as root per Shuah Khan Add better test logging for abnormal child termination per Shuah Khan Adjust ordering of charge/uncharge during transfer to avoid potentially hitting cgroup limit per Michal Koutný Adjust gpucg_try_charge critical section for charge transfer functionality Fix uninitialized return code error for dmabuf_try_charge error case v3: Remove Upstreaming Plan from gpu-cgroup.rst per John Stultz Use more common dual author commit message format per John Stultz Remove android from binder changes title per Todd Kjos Add a kselftest for this new behavior per Greg Kroah-Hartman Include details on behavior for all combinations of kernel/userspace versions in changelog (thanks Suren Baghdasaryan) per Greg Kroah-Hartman. Fix pid and uid types in binder UAPI header v2: See the previous revision of this change submitted by Hridya Valsaraju at: https://lore.kernel.org/all/20220115010622.3185921-1-hridya@google.com/ Move dma-buf cgroup charge transfer from a dma_buf_op defined by every heap to a single dma-buf function for all heaps per Daniel Vetter and Christian König. Pointers to struct gpucg and struct gpucg_device tracking the current associations were added to the dma_buf struct to achieve this. Fix incorrect Kconfig help section indentation per Randy Dunlap. History of the GPU cgroup controller ==================================== The GPU/DRM cgroup controller came into being when a consensus[1] was reached that the resources it tracked were unsuitable to be integrated into memcg. Originally, the proposed controller was specific to the DRM subsystem and was intended to track GEM buffers and GPU-specific resources[2]. In order to help establish a unified memory accounting model for all GPU and all related subsystems, Daniel Vetter put forth a suggestion to move it out of the DRM subsystem so that it can be used by other DMA-BUF exporters as well[3]. This RFC proposes an interface that does the same.

[PATCH v5 00/10] drm/hdcp: Pull HDCP auth/exchange/check into helpers
by Sean Paul 15 Jun '22

15 Jun '22

From: Sean Paul <seanpaul(a)chromium.org> Rebased set from November. Fixed a nit from Stephen in the msm patch and moved hdcp registers into the trogdor dtsi file to avoid differences with sc7180-based windows devices. The set is 4 patches lighter since some of the changes were accepted into msm. I'm still waiting for Intel review of the first 7 patches. Rodrigo/Jani, would you please provide your input so we can move forward with this set?

[PATCH 0/3] drm: move dsc data pointer from drm_panel to mipi_dsi_device
by Dmitry Baryshkov 15 Jun '22

15 Jun '22

To properly support DSC the sink driver (panel) has to pass DSC pps data to the source (DSI host). The commit 0f40ba48de3b ("drm/msm/dsi: Pass DSC params to drm_panel") added a pointer to the DSC data to the struct drm_panel. However this is not the ideal solution. First, this leaves DSC-supporting DSI sink bridges (like ANX7625 which support DSC decoding on the MIPI DSI inputs). Second, this does not play well with the panel_bridge. Drivers depending solely on the bridge chains will still have to lookup panel and fetch data from it. Last, but not least, the DSC data is not relevant for the wide variety of panels including DPI and LVDS panels. To solve all these problems, move struct drm_dsc_config pointer from struct drm_panel to struct mipi_host_device. This way MIPI DSI host driver receives DSC data during attach callback without additional lookups. Dependencies: this depends on the MSM DRM DSC patchset [1] being pulled in through the MSM DRM tree.
