[GIT PULL] fbdev changes for v4.21
by Bartlomiej Zolnierkiewicz 06 Jan '19

06 Jan '19

Hi Linus, Please pull fbdev changes for v4.21. This time the pull request is really small. The most notable changes are fixing fbcon to not cause crash on unregister_framebuffer() operation when there is more than one framebuffer, adding config option to center the bootup logo and making FB_BACKLIGHT config option tristate (which in turn uncovered incorrect FB_BACKLIGHT usage by DRM's nouveau driver). Please see the signed tag description for details.

[PATCH v8 20/25] powerpc, fbdev: Use arch_nvram_ops methods instead of nvram_read_byte() and nvram_write_byte()
by Finn Thain 05 Jan '19

Make use of arch_nvram_ops in device drivers so that the nvram_* function exports can be removed. Since they are no longer global symbols, rename the PPC32 nvram_* functions appropriately.

[PATCH v6 0/2] arm64: dts: Add sdm845 GPU/GMU and SMMU
by Jordan Crouse 04 Jan '19

04 Jan '19

Now that more of the sdm845 bindings are headed upstream this a refresh of of https://patchwork.freedesktop.org/series/39308/ to add bindings and nodes for the GPU/GMU and GPU SMMU for sdm845. This is based on : git://git.kernel.org/pub/scm/linux/kernel/git/agross/linux.git for-next with: https://lore.kernel.org/patchwork/patch/1018365/ This change requires the following dependencies: include/dt-bindings/power/qcom-rpmpd.h: https://patchwork.kernel.org/patch/10711119/ qcom,smmu-v2 binding: https://patchwork.kernel.org/patch/10581911/ v6: Update GPU bindings for a6xx and make the examples match the nodes and vice versa. Clean up types and rebase on https://lore.kernel.org/patchwork/patch/1018365/ to help facilitate merging. v5: Use symbolic names for the RPMH power levels defined in OPP table, move the opp tables as children of their respective nodes and rename the iommu device. v4: Rebase v3: Split GMU PDC region into two GPU specific sections, fix indentation, really use qcom,gmu for the phandle name v2: changed qcom,arc-level to qcom,level following discussion with Viresh; change gmu phandle to qcom,gmu per Rob *** BLURB HERE *** Jordan Crouse (2): dt-bindings: drm/msm/a6xx: Document GMU and update GPU bindings arm64: dts: sdm845: Add gpu and gmu device nodes .../devicetree/bindings/display/msm/gmu.txt | 56 ++++++++ .../devicetree/bindings/display/msm/gpu.txt | 41 +++++- arch/arm64/boot/dts/qcom/sdm845.dtsi | 123 ++++++++++++++++++ 3 files changed, 217 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/msm/gmu.txt -- 2.18.0

[Bug 105910] Graphical artifacts on unresposible surfaces on AMD Radeon RX 570

https://bugs.freedesktop.org/show_bug.cgi?id=105910 Bug ID: 105910 Summary: Graphical artifacts on unresposible surfaces on AMD Radeon RX 570 Product: Mesa Version: 17.3 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel(a)lists.freedesktop.org Reporter: nb(a)chebykin.org QA Contact: dri-devel(a)lists.freedesktop.org Created attachment 138627 --> https://bugs.freedesktop.org/attachment.cgi?id=138627&action=edit Example of artifacts Hello, I want to report some graphical artifacts with AMD Radeon RX 570 card. I've been noticing some random artifacts when I open/resize/close windows. I was able to narrow down this problem to mesa surfaces updating. For instance if i suspend program with such surface and try to resize it, I will see these artifacts. So I think there is a moment between receiving resize event and updating surface when driver somehow render those artifacts. I'm using Arch Linux with i3, but I was able to reproduce this bug on wayland by resizing alacritty terminal emulator. Versions: Kernel: 4.15.14-1-ARCH Mesa: libva-mesa-driver 17.3.7-1 mesa 17.3.7-1 mesa-vdpau 17.3.7-1 xf86-video-amdgpu 18.0.1-1 -- You are receiving this mail because: You are the assignee for the bug.

[PATCH v2] drm/amdgpu_vm: fix boolean expressions

[PATCH] drm/tilcdc: Register cpufreq notifier after we have initialized crtc

Register cpufreq notifier after we have initialized the crtc and unregister it before we remove the ctrc. Receiving a cpufreq notify without crtc causes a crash.
