[PATCH 0/9] drm/tegra: Various improvements
by Thierry Reding 28 Mar '21

28 Mar '21

From: Thierry Reding <treding(a)nvidia.com> Hi, this fixes a couple of oddities like slightly off DMA masks and add support for hardware cursors on newer chips as well as support for the sector layout bit in NVIDIA framebuffer modifiers. The first patch in this set is a small helper that I think might be useful to other drivers eventually, but if it isn't it's easily something I can carry in the Tegra driver. It'd be great to get an Acked-by on it from one of the drm-misc maintainers so that I can take it through the Tegra tree. James, I've added you on Cc on this one because it makes use of the extended framebuffer modifiers that you introduced a while back to support the sector layout mux on Tegra194. It'd be great to get your thoughts on this just so this is used as expected. Thanks, Thierry Thierry Reding (9): drm/fourcc: Add macro to check for the modifier vendor drm/tegra: dc: Inherit DMA mask drm/tegra: dc: Parameterize maximum resolution drm/tegra: dc: Implement hardware cursor on Tegra186 and later drm/tegra: fb: Add diagnostics for framebuffer modifiers drm/tegra: gem: Add a clarifying comment gpu: host1x: Add early init and late exit callbacks drm/tegra: Count number of display controllers at runtime drm/tegra: Support sector layout on Tegra194 drivers/gpu/drm/tegra/dc.c | 104 +++++++++++++++++++++++++++++++--- drivers/gpu/drm/tegra/dc.h | 6 ++ drivers/gpu/drm/tegra/drm.c | 13 ++++- drivers/gpu/drm/tegra/drm.h | 5 ++ drivers/gpu/drm/tegra/fb.c | 10 ++++ drivers/gpu/drm/tegra/gem.h | 6 ++ drivers/gpu/drm/tegra/hub.c | 41 +++++++++++++- drivers/gpu/drm/tegra/plane.c | 32 +++++++++++ drivers/gpu/host1x/bus.c | 31 ++++++++++ include/linux/host1x.h | 2 + include/uapi/drm/drm_fourcc.h | 3 + 11 files changed, 240 insertions(+), 13 deletions(-) -- 2.30.2

[Bug 212449] New: DDC requires amdgpu.dc=0, HDMI sound requires amdgpu.dc=1. Make them work together!

https://bugzilla.kernel.org/show_bug.cgi?id=212449 Bug ID: 212449 Summary: DDC requires amdgpu.dc=0, HDMI sound requires amdgpu.dc=1. Make them work together! Product: Drivers Version: 2.5 Kernel Version: 5.4.107 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: sdiconov(a)mail.ru Regression: No I need both DDC and HDMI audio functionality of my radeon RX card, but the amdgpu kernel driver fails to support both at the same time. I can either use DDC with "amdgpu.hw_i2c=0 amdgpu.dc=0" OR HDMI audio with "amdgpu.dc=1". The "dc=1" kernel switch disables DDC and "dc=0" disables HDMI audio. The "dcfeaturemask" option might need a new flag to selectively allow i2c communication with the display while still allowing audio to work over HDMI. ___Details___ I run a radeon RX card supported by the amdgpu module "# lspci 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

[AMD/ATI] Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X]" It has 1 DP, 1 DVI and 1 HDMI outs. The GPU is connected to: 1) a Dell U3011 display via DVI (only 2560x1600 video) and 2) an audio receiver via HDMI (only audio). The display is shared with another computer, which takes up the display's DP port. The receiver does not support 2K/4K video resolution and serves as a hifi DAC+amplifier only. HDMI is the only way to pass digtal PCM 5.1 audio. I need DDC to switch video inputs of the Dell U3011 display, because its sensor buttons and on-screen menus are a real pain to use. gddccontrol is a handy linux gui app to do it, but it needs i2c and ddc support (which get disabled by the dc=1 switch). -- You may reply to this email to add a comment.

[Bug 212259] New: Entire graphics stack locks up when running SteamVR and sometimes Sway; is sometimes unrecoverable
by bugzilla-daemon＠bugzilla.kernel.org 27 Mar '21

https://bugzilla.kernel.org/show_bug.cgi?id=212259 Bug ID: 212259 Summary: Entire graphics stack locks up when running SteamVR and sometimes Sway; is sometimes unrecoverable Product: Drivers Version: 2.5 Kernel Version: 5.11.0 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: happysmash27(a)protonmail.com Regression: No Created attachment 295831 --> https://bugzilla.kernel.org/attachment.cgi?id=295831&action=edit Last 406 lines of dmesg at the time of error This bug is driving me nuts! First time, it frequently happened when I ran Sway and LXDE at the same time, where my entire graphics stack would freeze and I would be unable to switch virtual TTYs or even kill X, even with kill -9 on everything. Now, I am experiencing this bug again, this time with SteamVR, and at a MUCH higher frequency. It seems to happen, fairly randomly, whenever I start SteamVR, but seems to be more likely when my system has been running for a long time, or when Waterfox has been running for a long time. A couple weeks ago I found a way to reset my GPU as a workaround to the bug (https://www.reddit.com/r/linuxquestions/comments/lpiwkg/how_to_reset_graphi…), but today, this did not work. My screen went black, but I was still unable to kill -9 X, even after trying the reset many times. In dmesg, there were messages about the reset still being in-progress, but I did not see anything seem to change. Eventually, I decided to give up on gracefully fixing this bug with no downtime to my website and poweroff, then hold the power button of my computer after the HDD activity light went off as even powering off doesn't seem to work properly with this bug. Only then, could I reboot and recover. I have attached the end of the most recent dmesg where this failed. I also have more dmesgs that may or may not be the same bug, but the attachment field only allows for one. -- You may reply to this email to add a comment.

[PATCH v2 00/28] drm/msm/dsi: refactor MSM DSI PHY/PLL drivers
by Dmitry Baryshkov 27 Mar '21

27 Mar '21

Restructure MSM DSI PHY drivers. What started as an attempt to grok the overcomplicated PHY drivers, has lead up to the idea of merging PHY and PLL code, reducing abstractions, code duplication, dropping dead code, etc. The patches were mainly tested on RB5 (sm8250, 7nm) and DB410c (apq8016, 28nm-lp) and lightly tested on RB3 (sdm845, 10nm). External dependency for sm8250: https://lore.kernel.org/linux-arm-msm/20210317144039.556409-10-dmitry.barys… The patch 'clk: fixed: add devm helper for clk_hw_register_fixed_factor()' is already a part of mainline as of 5.12-rc1, but is included here for completeness to fix compilation issues (as msm-next is based on 5.11-rc5). Changes since v1: - Rebase on top of msm/msm-next - Reorder patches to follow logical sequence - Add sc7180 clocks assignment - Drop sm8250 clocks assignment, as respective file is not updated in msm/msm-next Changes since RFC: - Reorder patches to move global clock patches in the beginning and dtsi patches where they are required. - remove msm_dsi_phy_set_src_pll() and guess src_pll_id using PHY usecase. The following changes since commit 627dc55c273dab308303a5217bd3e767d7083ddb: drm/msm/disp/dpu1: icc path needs to be set before dpu runtime resume (2021-03-22 18:52:34 -0700) are available in the Git repository at: https://git.linaro.org/people/dmitry.baryshkov/kernel.git dsi-phy-2 for you to fetch changes up to 0fec912264e9ee8f0ebbad12e2711843d7d9e0ac: drm/msm/dsi: stop passing src_pll_id to the phy_enable call (2021-03-24 18:14:39 +0300) ---------------------------------------------------------------- Daniel Palmer (1): clk: fixed: add devm helper for clk_hw_register_fixed_factor() Dmitry Baryshkov (27): clk: mux: provide devm_clk_hw_register_mux() clk: divider: add devm_clk_hw_register_divider drm/msm/dsi: replace PHY's init callback with configurable data drm/msm/dsi: fuse dsi_pll_* code into dsi_phy_* code drm/msm/dsi: drop multiple pll enable_seq support drm/msm/dsi: move all PLL callbacks into PHY config struct drm/msm/dsi: drop global msm_dsi_phy_type enumaration drm/msm/dsi: move min/max PLL rate to phy config drm/msm/dsi: remove msm_dsi_pll_set_usecase drm/msm/dsi: stop setting clock parents manually arm64: dts: qcom: sdm845: assign DSI clock source parents arm64: dts: qcom: sc7180: assign DSI clock source parents drm/msm/dsi: push provided clocks handling into a generic code drm/msm/dsi: use devm_clk_*register to registe DSI PHY clocks drm/msm/dsi: use devm_of_clk_add_hw_provider drm/msm/dsi: make save/restore_state phy-level functions drm/msm/dsi: drop vco_delay setting from 7nm, 10nm, 14nm drivers drm/msm/dpu: simplify vco_delay handling in dsi_phy_28nm driver drm/msi/dsi: inline msm_dsi_pll_helper_clk_prepare/unprepare drm/msm/dsi: make save_state/restore_state callbacks accept msm_dsi_phy drm/msm/dsi: drop msm_dsi_pll abstracton drm/msm/dsi: drop PLL accessor functions drm/msm/dsi: move ioremaps to dsi_phy_driver_probe drm/msm/dsi: remove duplicate fields from dsi_pll_Nnm instances drm/msm/dsi: remove temp data from global pll structure drm/msm/dsi: inline msm_dsi_phy_set_src_pll drm/msm/dsi: stop passing src_pll_id to the phy_enable call arch/arm64/boot/dts/qcom/sc7180.dtsi | 3 + arch/arm64/boot/dts/qcom/sdm845.dtsi | 6 + drivers/clk/clk-fixed-factor.c | 39 +- drivers/clk/clk-mux.c | 35 + drivers/gpu/drm/msm/Kconfig | 8 - drivers/gpu/drm/msm/Makefile | 9 - drivers/gpu/drm/msm/dsi/dsi.h | 58 +- drivers/gpu/drm/msm/dsi/dsi_host.c | 51 -- drivers/gpu/drm/msm/dsi/dsi_manager.c | 29 +- drivers/gpu/drm/msm/dsi/phy/dsi_phy.c | 150 ++-- drivers/gpu/drm/msm/dsi/phy/dsi_phy.h | 41 +- drivers/gpu/drm/msm/dsi/phy/dsi_phy_10nm.c | 745 ++++++++++++++- drivers/gpu/drm/msm/dsi/phy/dsi_phy_14nm.c | 939 ++++++++++++++++++- drivers/gpu/drm/msm/dsi/phy/dsi_phy_20nm.c | 16 +- drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c | 654 +++++++++++++- drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm_8960.c | 479 +++++++++- drivers/gpu/drm/msm/dsi/phy/dsi_phy_7nm.c | 772 +++++++++++++++- drivers/gpu/drm/msm/dsi/pll/dsi_pll.c | 184 ---- drivers/gpu/drm/msm/dsi/pll/dsi_pll.h | 132 --- drivers/gpu/drm/msm/dsi/pll/dsi_pll_10nm.c | 881 ------------------ drivers/gpu/drm/msm/dsi/pll/dsi_pll_14nm.c | 1096 ----------------------- drivers/gpu/drm/msm/dsi/pll/dsi_pll_28nm.c | 643 ------------- drivers/gpu/drm/msm/dsi/pll/dsi_pll_28nm_8960.c | 526 ----------- drivers/gpu/drm/msm/dsi/pll/dsi_pll_7nm.c | 913 ------------------- include/linux/clk-provider.h | 34 +- 25 files changed, 3722 insertions(+), 4721 deletions(-) delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll.c delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll.h delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll_10nm.c delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll_14nm.c delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll_28nm.c delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll_28nm_8960.c delete mode 100644 drivers/gpu/drm/msm/dsi/pll/dsi_pll_7nm.c
