DMA-buf and uncached system memory
by Christian König 24 Jun '22

24 Jun '22

Hi guys, we are currently working an Freesync and direct scan out from system memory on AMD APUs in A+A laptops. On problem we stumbled over is that our display hardware needs to scan out from uncached system memory and we currently don't have a way to communicate that through DMA-buf. For our specific use case at hand we are going to implement something driver specific, but the question is should we have something more generic for this? After all the system memory access pattern is a PCIe extension and as such something generic. Regards, Christian.

https://bugzilla.kernel.org/show_bug.cgi?id=201957 Bug ID: 201957 Summary: amdgpu: ring gfx timeout Product: Drivers Version: 2.5 Kernel Version: 4.19.8, 4.20-rc5 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: felix.adrianto(a)gmail.com Regression: No Error message: [Dec 5 22:08] amdgpu 0000:23:00.0: GPU fault detected: 146 0x0000480c for process yuzu pid 2920 thread yuzu:cs0 pid 2935 [ +0.000005] amdgpu 0000:23:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 [ +0.000002] amdgpu 0000:23:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0604800C [ +0.000003] amdgpu 0000:23:00.0: VM fault (0x0c, vmid 3, pasid 32770) at page 0, read from 'TC4' (0x54433400) (72) [ +10.053011] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=37241, emitted seq=37244 [ +0.000007] [drm] GPU recovery disabled. How to reproduce the issue: 1. Playing with yuzu-emulator 2. Load Super Mario Odyssey 3. Start new game 4. When Mario is about to jump for the first time after being woken up by Cappy, this bug must occur. During the issue, the following occured: 1. Graphic locked up. 2. System can be access through SSH. System specification: Debian Sid Radeon RX 580 I have tried the following combination: 1. Kernel 4.17, 4.18, 4.19, 4.20, drm-next-4.21.wip 2. Mesa 18.2, 18.3, 19.0-development branch But none of the above combination fixes the issue. Let me know if you need more information and more testing from me. -- You are receiving this mail because: You are watching the assignee of the bug.

[Bug 172421] New: radeon: allow to set the TMDS frequency by a special kernel parameter
by bugzilla-daemon＠bugzilla.kernel.org 19 Jun '22

https://bugzilla.kernel.org/show_bug.cgi?id=172421 Bug ID: 172421 Summary: radeon: allow to set the TMDS frequency by a special kernel parameter Product: Drivers Version: 2.5 Kernel Version: 4.8.0-rc7+ Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: enhancement Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: estellnb(a)elstel.org Regression: No Despite different claims by ATI in 2016 Radeon R5 230 graphics cards featuring HDMI, DVI and VGA had originally been sold as 4K-ready up to the year 2015. The only prove I have for this is a comercial invoice from Nexus Mobile and a packaging card. As far as I know Radeon R5 230 cards currently sold can still be run stable and reliable under UltraHD provided that you apply the right kernel patch (see for the attachement). Unfortunately neither my former merchant nor ATI have responded about my questions concerning this change in trade and marketing policy. My request would now be to integrate the provided patch into the mainline kernel. It does not change the behaviour of the radeon driver unless you specify a nonzero value for the radeon.hdmimhz parameter. If you do I have tested the R5 230 cards I have to run stable and reliably for days. At least the 2GB variant of this card has largely sufficient resources for proficient desktop computing under UltraHD including image manipulation in 3840x2160. While never officially discussed for the radeon driver nouveau is already implementing a similar parameter called nouveau.hdmimhz since kernel 4.5.x. Though it thereby becomes possible to specify a hdmimhz that is far above the cards technical possibilties the nouveau developers I have talked with say that it would rarely be possible to damage any card by overcloking the TMDS. In deed I have successfully been overclocking my GeForce 9600M GT to feature 4K/2160p. Even specifying values considerable higher than 225MHz did not damage my GeForce 9600M GT though the screen stayed black upon the nouveau driver initialization. While the Radeon R5 230 works well at 297MHz (as long as you specify that via radeon.hdmimhz) I have similarly to the GeForce 9600M GT tried to overclock a Radeon R7 240. It did produce stable images at a higher hdmimhz like 330 though the HDMI input of my monitor features no more than 30Hz at 3840x2160 (tested with or without a DP-adapter). While it remains questionable if the provided patch can improve things for newer Radeon cards I would believe it to be beneficial for some elder cards. At least it is known to be beneficial for the R5 230 initially marketed as 4K-ready. The according radeon patch provided with this report has so far already been accepted by the Mageia 6 distribution. Though the attached patch is for application at the current 4.8.0-rcX+ kernels most of my machines that rely on it still run with 4.6.0. -- You are receiving this mail because: You are watching the assignee of the bug.

[PATCH v2 00/15] DRM fbconv helpers for converting fbdev drivers
by Thomas Zimmermann 30 May '22

30 May '22

(was: DRM driver for fbdev devices) This is version 2 of the fbdev conversion helpers. It's more or less a rewrite of the original patchset. The fbdev subsystem is considered legacy and will probably be removed at some point. This would mean the loss of a signifanct number of drivers. Some of the affected hardware is not in use any longer, but some hardware is still around and provides good(-enough) framebuffers. The fbconv helpers allow for running the current DRM stack on top of fbdev drivers. It's a set of functions that convert between fbdev interfaces and DRM interfaces. Based on SHMEM and simple KMS helpers, it only offers the basic functionality of a framebuffer, but should be compatible with most existing fbdev drivers. A DRM driver using fbconv helpers consists of * DRM stub code that calls into fbconv helpers, and * the original fbdev driver code. The fbdev driver code has to be modified to register itself with the stub driver instead of the fbdev core framework. A tutorial on how to use the helpers is part of this patchset. The resulting driver hybrid can be refactored into a first-class DRM driver. The fbconv helpers contain a number of comments, labeled 'DRM porting note', which explain the required steps. I tested the current patchset with the following drivers: atyfb, aty128fb, matroxfb, pm2fb, pm3fb, rivafb, s3fb, savagefb, sisfb, tdfxfb and tridentfb. With each, I was able to successfully start with fbcon enabled, run weston and X11. The drivers are available at [1]. For reference, the patchset includes the Matrox stub driver. v2: * rename to fbconv helpers * rewrite as helper library * switch over to simple KMS helpers * switch over to SHMEM * add documentation [1] https://gitlab.freedesktop.org/tzimmermann/linux/commits/fbconv-plus-drivers Thomas Zimmermann (15): fbdev: Export fb_check_foreignness() fbdev: Export FBPIXMAPSIZE drm/simple-kms-helper: Add mode_fixup() to simple display pipe drm: Add fbconv helper module drm/fbconv: Add DRM <-> fbdev pixel-format conversion drm/fbconv: Add mode conversion DRM <-> fbdev drm/fbconv: Add modesetting infrastructure drm/fbconv: Add plane-state check and update drm/fbconv: Mode-setting pipeline enable / disable drm/fbconv: Reimplement several fbdev interfaces drm/fbconv: Add helpers for init and cleanup of fb_info structures drm/fbconv: Add helper documentation staging: Add mgakms driver staging/mgakms: Import matroxfb driver source code staging/mgakms: Update matroxfb driver code for DRM Documentation/gpu/drm-kms-helpers.rst | 12 + Documentation/gpu/todo.rst | 15 + drivers/gpu/drm/Kconfig | 11 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/drm_fbconv_helper.c | 2126 +++++++++++++++++ drivers/gpu/drm/drm_simple_kms_helper.c | 15 + drivers/staging/Kconfig | 2 + drivers/staging/Makefile | 1 + drivers/staging/mgakms/Kconfig | 18 + drivers/staging/mgakms/Makefile | 17 + drivers/staging/mgakms/g450_pll.c | 539 +++++ drivers/staging/mgakms/g450_pll.h | 13 + drivers/staging/mgakms/i2c-matroxfb.c | 238 ++ drivers/staging/mgakms/matroxfb_DAC1064.c | 1082 +++++++++ drivers/staging/mgakms/matroxfb_DAC1064.h | 174 ++ drivers/staging/mgakms/matroxfb_Ti3026.c | 746 ++++++ drivers/staging/mgakms/matroxfb_Ti3026.h | 10 + drivers/staging/mgakms/matroxfb_accel.c | 519 +++++ drivers/staging/mgakms/matroxfb_accel.h | 9 + drivers/staging/mgakms/matroxfb_base.c | 2592 +++++++++++++++++++++ drivers/staging/mgakms/matroxfb_base.h | 700 ++++++ drivers/staging/mgakms/matroxfb_crtc2.h | 35 + drivers/staging/mgakms/matroxfb_g450.c | 640 +++++ drivers/staging/mgakms/matroxfb_g450.h | 10 + drivers/staging/mgakms/matroxfb_maven.h | 21 + drivers/staging/mgakms/matroxfb_misc.c | 815 +++++++ drivers/staging/mgakms/matroxfb_misc.h | 22 + drivers/staging/mgakms/mga_device.c | 68 + drivers/staging/mgakms/mga_device.h | 30 + drivers/staging/mgakms/mga_drv.c | 129 + drivers/staging/mgakms/mga_drv.h | 14 + drivers/video/fbdev/core/fbmem.c | 5 +- include/drm/drm_fbconv_helper.h | 150 ++ include/drm/drm_simple_kms_helper.h | 43 + include/linux/fb.h | 3 + 35 files changed, 10822 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/drm_fbconv_helper.c create mode 100644 drivers/staging/mgakms/Kconfig create mode 100644 drivers/staging/mgakms/Makefile create mode 100644 drivers/staging/mgakms/g450_pll.c create mode 100644 drivers/staging/mgakms/g450_pll.h create mode 100644 drivers/staging/mgakms/i2c-matroxfb.c create mode 100644 drivers/staging/mgakms/matroxfb_DAC1064.c create mode 100644 drivers/staging/mgakms/matroxfb_DAC1064.h create mode 100644 drivers/staging/mgakms/matroxfb_Ti3026.c create mode 100644 drivers/staging/mgakms/matroxfb_Ti3026.h create mode 100644 drivers/staging/mgakms/matroxfb_accel.c create mode 100644 drivers/staging/mgakms/matroxfb_accel.h create mode 100644 drivers/staging/mgakms/matroxfb_base.c create mode 100644 drivers/staging/mgakms/matroxfb_base.h create mode 100644 drivers/staging/mgakms/matroxfb_crtc2.h create mode 100644 drivers/staging/mgakms/matroxfb_g450.c create mode 100644 drivers/staging/mgakms/matroxfb_g450.h create mode 100644 drivers/staging/mgakms/matroxfb_maven.h create mode 100644 drivers/staging/mgakms/matroxfb_misc.c create mode 100644 drivers/staging/mgakms/matroxfb_misc.h create mode 100644 drivers/staging/mgakms/mga_device.c create mode 100644 drivers/staging/mgakms/mga_device.h create mode 100644 drivers/staging/mgakms/mga_drv.c create mode 100644 drivers/staging/mgakms/mga_drv.h create mode 100644 include/drm/drm_fbconv_helper.h -- 2.23.0

Hi! This is a prototype of HDMI output support for the Renesas r8a7795 SoC and Salvator-X board. It is based on the renesas-devel-20160516-v4.6 tree and includes the bridge API conversion patches to the adv7511 and rcar-du drivers written by Archit Taneja. The obvious issue with this series is the awkward binding of the dw-hdmi bridge IP, which can be seen in the "drm: rcar-du: Add dw_hdmi driver startup" patch. Any comments on how to implement this interface properly are much appreciated. Functionally, this series works as expected on both connectors, but EDID reading is currently broken.
