[PATCH 0/7] Fix stealing guc_ids + test
by Matthew Brost 11 Dec '21

11 Dec '21

Patches 1 & 2 address bugs in stealing of guc_ids and patch 7 tests this path. Patches 4-6 address some issues with the CTs exposed by the selftest in patch 7. Basically if a lot of contexts were all deregistered all at once, the CT channel could deadlock. Patch 3 is a small fix that is already review but just included for CI.

[PATCH v4 0/6] Expand display core documentation
by Rodrigo Siqueira 10 Dec '21

10 Dec '21

Display Core (DC) is one of the components under amdgpu, and it has multiple features directly related to the KMS API. Unfortunately, we don't have enough documentation about DC in the upstream, which makes the life of some external contributors a little bit more challenging. For these reasons, this patchset reworks part of the DC documentation and introduces a new set of details on how the display core works on DCN IP. Another improvement that this documentation effort tries to bring is making explicit some of our hardware-specific details to guide user-space developers better. In my view, it is easier to review this series if you apply it in your local kernel and build the HTML version (make htmldocs). I'm suggesting this approach because I added a few SVG diagrams that will be easier to see in the HTML version. If you cannot build the documentation, try to open the SVG images while reviewing the content. In summary, in this series, you will find: 1. Patch 1: Re-arrange of display core documentation. This is preparation work for the other patches, but it is also a way to expand this documentation. 2. Patch 2 to 4: Document some common debug options related to display. 3. Patch 5: This patch provides an overview of how our display core next works and a brief explanation of each component. 4. Patch 6: We use a lot of acronyms in our driver; for this reason, we exposed a glossary with common terms used by display core. Please let us know what you think we can improve this series and what kind of content you want to see for the next series. Changes since V3: - Add new acronyms to amdgpu glossary - Add link between dc and amdgpu glossary Changes since V2: - Add a comment about MMHUBBUB Changes since V1: - Group amdgpu documentation together. - Create index pages. - Mirror display folder in the documentation. - Divide glossary based on driver context. - Make terms more consistent and update CPLIB - Add new acronyms to the glossary Thanks Siqueira Rodrigo Siqueira (6): Documentation/gpu: Reorganize DC documentation Documentation/gpu: Document amdgpu_dm_visual_confirm debugfs entry Documentation/gpu: Document pipe split visual confirmation Documentation/gpu: How to collect DTN log Documentation/gpu: Add basic overview of DC pipeline Documentation/gpu: Add amdgpu and dc glossary Documentation/gpu/amdgpu-dc.rst | 74 -- Documentation/gpu/amdgpu/amdgpu-glossary.rst | 87 ++ .../gpu/amdgpu/display/config_example.svg | 414 ++++++ Documentation/gpu/amdgpu/display/dc-debug.rst | 77 ++ .../gpu/amdgpu/display/dc-glossary.rst | 237 ++++ .../amdgpu/display/dc_pipeline_overview.svg | 1125 +++++++++++++++++ .../gpu/amdgpu/display/dcn-overview.rst | 171 +++ .../gpu/amdgpu/display/display-manager.rst | 42 + .../gpu/amdgpu/display/global_sync_vblank.svg | 485 +++++++ Documentation/gpu/amdgpu/display/index.rst | 29 + .../gpu/{amdgpu.rst => amdgpu/index.rst} | 25 +- Documentation/gpu/drivers.rst | 3 +- 12 files changed, 2690 insertions(+), 79 deletions(-) delete mode 100644 Documentation/gpu/amdgpu-dc.rst create mode 100644 Documentation/gpu/amdgpu/amdgpu-glossary.rst create mode 100644 Documentation/gpu/amdgpu/display/config_example.svg create mode 100644 Documentation/gpu/amdgpu/display/dc-debug.rst create mode 100644 Documentation/gpu/amdgpu/display/dc-glossary.rst create mode 100644 Documentation/gpu/amdgpu/display/dc_pipeline_overview.svg create mode 100644 Documentation/gpu/amdgpu/display/dcn-overview.rst create mode 100644 Documentation/gpu/amdgpu/display/display-manager.rst create mode 100644 Documentation/gpu/amdgpu/display/global_sync_vblank.svg create mode 100644 Documentation/gpu/amdgpu/display/index.rst rename Documentation/gpu/{amdgpu.rst => amdgpu/index.rst} (95%) -- 2.25.1

[PATCH 1/2] drm/privacy_screen_x86: Add entry for ChromeOS privacy-screen
by Rajat Jain 10 Dec '21

10 Dec '21

Add a static entry in the x86 table, to detect and wait for privacy-screen on some ChromeOS platforms. Please note that this means that if CONFIG_CHROMEOS_PRIVACY_SCREEN is enabled, and if "GOOG0010" device is found in ACPI, then the i915 probe shall return EPROBE_DEFER until a platform driver actually registers the privacy-screen: https://hansdegoede.livejournal.com/25948.html Signed-off-by: Rajat Jain <rajatja(a)google.com> --- This patch is rebased on top of linux-next/master drivers/gpu/drm/drm_privacy_screen_x86.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/drivers/gpu/drm/drm_privacy_screen_x86.c b/drivers/gpu/drm/drm_privacy_screen_x86.c index a2cafb294ca6..3728870a98e7 100644 --- a/drivers/gpu/drm/drm_privacy_screen_x86.c +++ b/drivers/gpu/drm/drm_privacy_screen_x86.c @@ -45,6 +45,17 @@ static bool __init detect_thinkpad_privacy_screen(void) return (output & 0x10000) ? true : false; } +#elif IS_ENABLED(CONFIG_CHROMEOS_PRIVACY_SCREEN) + +static bool __init detect_chromeos_privacy_screen(void) +{ + if (!acpi_dev_present("GOOG0010", NULL, -1)) + return false; + + pr_info("%s: Need to wait for ChromeOS privacy-screen", __func__); + return true; + +} #endif static const struct arch_init_data arch_init_data[] __initconst = { @@ -57,6 +68,15 @@ static const struct arch_init_data arch_init_data[] __initconst = { }, .detect = detect_thinkpad_privacy_screen, }, +#elif IS_ENABLED(CONFIG_CHROMEOS_PRIVACY_SCREEN) + { + .lookup = { + .dev_id = NULL, + .con_id = NULL, + .provider = "privacy_screen-GOOG0010:00", + }, + .detect = detect_chromeos_privacy_screen, + }, #endif }; -- 2.34.1.173.g76aa8bc2d0-goog

[PATCH 00/17] MediaTek MT8192 APU
by Flora Fu 10 Dec '21

10 Dec '21

The MediaTek AI Processing Unit (APU) is a proprietary hardware in the SoC to support AI functions. The patches support the MT8192 APU runs on internal microprocessor. Software packages contins mailbox, iommu, APU remote processor, power control, middleware and debug looger. This series is based on drivers implemented in MT8192 apu power domain[1], apu SMC[2] and IOMMU[2] patches.

[PATCH] drm: i915: display: intel_dmc: Fixes an unsigned subtraction which can never be negative.

smatch warning: drivers/gpu/drm/i915/display/intel_dmc.c:601 parse_dmc_fw() warn: unsigned 'fw->size - offset' is never less than zero Firmware size is size_t and offset is u32. So the subtraction is unsigned which can never be less than zero.
