[PATCH v5] drm/msm/disp/dpu1: add inline rotation support for sc7280 target
by Vinod Polimera 16 Mar '22

16 Mar '22

- Some DPU versions support inline rot90. It is supported only for limited amount of UBWC formats. - There are two versions of inline rotators, v1 (present on sm8250 and sm7250) and v2 (sc7280). These versions differ in the list of supported formats and in the scaler possibilities. Changes in RFC: - Rebase changes to the latest code base. - Append rotation config variables with v2 and remove unused variables.(Dmitry) - Move pixel_ext setup separately from scaler3 config.(Dmitry) - Add 270 degree rotation to supported rotation list.(Dmitry) Changes in V2: - Remove unused macros and fix indentation. - Add check if 90 rotation is supported and add supported rotations to rot_cfg. Changes in V3: - Fix indentation. - Move rot_supported to sspp capabilities. (Dmitry) - Config pixel_ext based on src_h/src_w directly. (Dmitry) - Misc changes. Changes in V4: - Pass boolean value to sspp blk based on supported rotations for each hw. Changes in V5: - update boolean value to true/false and add it for qcm2290.

[PATCH v3 0/3] Move #define wbvind_on_all_cpus
by Michael Cheng 16 Mar '22

16 Mar '22

This series moves the logic for wbvind_on_all_cpus to drm_cache. The logic changes a little here, if platform is not x86 then we throw out a warning for when wbvind_on_all_cpus is being called. v2(Michael Cheng): Move and redo logic for wbvind_on_all_cpus. Also add drm_cache.h where the function is being called and remove uneeded header files. v3(Michael Cheng): Updated commit messages.

The documentation for drm_rotation_simplify() uses DRM_MODE_ROTATE_X, while it's clear the the comment should mention DRM_MODE_REFLECT_X instead.

[PATCH v10 00/13] Add GuC Error Capture Support
by Alan Previn 16 Mar '22

16 Mar '22

This series: 1. Enables support of GuC to report error-state-capture using a list of MMIO registers the driver registers and GuC will dump, log and notify right before a GuC triggered engine-reset event. 2. Updates the ADS blob creation to register said lists of global, engine class and engine instance registers with GuC. 3. Defines tables of register lists that are global or engine class or engine instance in scope. 4. Updates usage and buffer-state data for the regions of the shared GuC log-buffer to accomdate both the existing relay logging of general debug logs along with the new error state capture usage. 5. Using a pool of preallocated memory, provide ability to extract and format the GuC reported register-capture data into chunks consistent with existing i915 error- state collection flows and structures. 6. Connects the i915_gpu_coredump reporting function to the GuC error capture module to print all GuC error state capture dumps that is reported. This is the 8th rev of this series with the first 3 revs labelled as RFC. Prior receipts of rvb's: - Patch #2, #3, #4, #5, #10, #11, #12, #13 have received R-v-b's from Umesh Nerlige Ramappa <umesh.nerlige.ramappa(a)intel.com> - Patch #6, #7, #8, #9 has received an R-v-b from Matthew Brost <matthew.brost(a)intel.com>. NOTE: some of these came in on the trybot series. https://patchwork.freedesktop.org/series/100831/ Changes from prior revs: v10:- Rebase on latest drm-tip again. Fix a number of checkpatch warnings and an error Reported-by: kernel test robot <lkp(a)intel.com>. v9: - Rebase on latest drm-tip to solve CI merge-build error. v8: - Fix a bug found by CI in rev7: Create a cached ADS capture list for null-header like the other lists. - Fixed a bug on the ggtt offset calculation in the ADS population loop. Thanks to Matt Brost. - Change the storage uses for initial allocation and caching of the ADS register lists so we only store a regular pointer instead of file handle. - Multiple improvements on code styling, variable names, comments and code reduction from Umesh suggestions across multiple patches. v7: - Rebased on lastest drm_tip that has the ADS now using shmem based ads_blob_write utilities. Stress test was performed with this patch included to fix a legacy bug: https://patchwork.freedesktop.org/series/100768/ v6: - In patch #1, ADS reg-list population, we now alloc regular memory to create the lists and cache them for simpler and faster use by GuC ADS module at init, suspend-resume and reset cycles. This was in response to review comments from Lucas De Marchi that also wanted to ensure the GuC ADS module owns the final copying into the ADS phyical memory. - Thanks to Jani Nikula for pointing out that patch #2 and #3 should ensure static tables as constant and dynamic lists should be allocated and cached but attached to the GT level for the case of multiple cards with different fusings for steered registers. These are addressed now along with multiple code style fixups (thanks to review comment from Umesh) and splitting the steered register list generation as a seperate patch. - The extraction functionality, Patch #10 and #11 (was patch #7), has fixed all of Umesh's review comments related to the code styling. Additionally, it was discovered during stress tests that the extraction function could be called by the ct processing thread at the same time as the start of a GT reset event. Thus, a redesign was done whereby the linked list of processed capture-output-nodes are allocated up front and reused throughout the driver's life to ensure no memory locks are taken during extraction. - For patch #6 (now 7, 8 and 9), updates to intel_guc_log was split into smaller chunks and the log_state structure was returned back to inside of the intel_guc_log struct as opposed to the intel_guc struct in prior rev. This is in response to review comments by Matt Brost. - #Patch 13 (previously #10) is mostly identical but addresses all of the code styling comments reviews from Umesh. v5: - Added Gen9->Gen11 register list for CI coverage that included Gen9 with GuC submission. - Redesigned the extraction of the GuC error-capture dumps by grouping them into complete per-engine-reset nodes. Complete here means each node includes the global, engine-class and engine-instance register lists in a single structure. - Extraction is decoupled from the print-out. We now do the extraction immediately when receiving the G2H for error-capture notification. A link list of nodes is maintained with a FIFO based threshold while awaiting retrieval from i915_gpu_coredump's capture_engine function. - Added new plumbing through the i915_gpu_coredump allocation and capture functions to include a flag that is used indicate that GuC had triggered the reset. This new plumbing guarantees an exact match from i915_gpu_coredump's per-engine vma recording and node-retrieval from the guc-error-capture. - Broke the coredump gt_global capture and recording functions into smaller subsets so we can reuse as much of the existing legacy register reading + printing functions and only rely on GuC error-capture for the smaller subset of registers that are tied to engine workload execution. - Updated the register list to follow the legacy execlist format of printout. v4: - Rebased on latest drm-tip that has been merged with the support of GuC firmware version 69.0.3 that is required for GuC error-state-catpure to work. - Added register list for DG2 which is the same as XE_LP except an additional steering register set. - Fixed a bug in the end of capture parsing loop in intel_guc_capture_out_print_next_group that was not properly comparing the engine-instance and engine- class being parsed against the one that triggered the i915_gpu_coredump. v3: - Fixed all review comments from rev2 except the following: - Michal Wajdeczko proposed adding a seperate function to lookup register string nameslookup (based on offset) but decided against it because of offset conflicts and the current table layout is easier to maintain. - Last set of checkpatch errors pertaining to "COMPLEX MACROS" should be fixed on next rev. - Abstracted internal-to-guc-capture information into a new __guc_state_capture_priv structure that allows the exclusion of intel_guc.h and intel_guc_fwif.h from intel_guc_capture.h. Now, only the first 2 patches have a wider build time impact because of the changes to intel_guc_fwif.h but subsequent changes to guc-capture internal structures or firmware interfaces used solely by guc-capture module shoudn't impact the rest of the driver build. - Added missing Gen12LP registers and added slice+subslice indices when reporting extended steered registers. - Add additional checks to ensure that the GuC reported error capture information matches the i915_gpu_coredump that is being printed before we print out the corresponding VMA dumps such as the batch buffer. v2: - Ignore - failed CI retest.

[PATCH 0/3] i915: General multicast steering updates
by Matt Roper 16 Mar '22

16 Mar '22

A few minor steering updates, mostly to prepare for other upcoming work. We'll soon be doing most of our steering explicitly, rather than relying on implicit steering as we do now, so reporting the steering assignments in debugfs will be helpful for debugging. We also have some features coming up soon that need to be able to issue unicast writes to a specific register instance. Finally, we need to inform the GuC about proper register steering so that it knows how to handle register save/restore operations.

[PATCH 0/9] drm: Support GEM SHMEM fbdev without shadow FB
by Thomas Zimmermann 15 Mar '22

15 Mar '22

Rework the fbdev deferred-I/O to not interfere with fields of struct page. Make the code more flexible and implement GEM SHMEM mmap on top of it. This patchset removes the need for a special shadow framebuffer for fbdev mmap when using GEM SHMEM. SHMEM pages are now mmap'ed from /dev/fb directly. Patches 2 and 3 rework the fbdev deferred I/O code. It now allows drivers to have better control of the mmap operations. All references to fields in struct page are gone. The rsp state is help in a separate pageref structure. Patches 4 to 7 provide callbacks an helpers to implement deferred I/O with DRM drivers. Specifically, patch 6 introduces a callback to create a dumb buffer for fbdev. This will be useful for many drivers that currently cannot use generic fbdev emulation because of special placement needs of the BO, such as amdgpu or radeon. The drivers can handle the differences to regular dumb buffers in their new callback implementation. Patch 8 extends the GEM SHMEM memory manager with a new helper for fbdev dumb-buffer creation. The returned BO has it's mmap set up to implement deferred I/O with SHMEM pages. No additional shadow buffer is requires any longer. Many drivers can immediatelly benefit from this change. Patch 9 extends virtgpu to support fbdev dumb buffers. It's build on top of GEM SHMEM, but has some modifications that need to be implemented for fbdev as well. There's no immediate fbdev performance improvement from this patchset. Most of all, it removes unnecessary shadow framebuffers and rsp memcpys. A shadow fb for a FullHD display is ~8 MiB, which we now save. The patches do reduce latency between drawing to the fbdev buffer to displaying on the screen. Watching a video on the fbdev console felt smoother and had less flickering.
