[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.

[RFC 00/21] Renesas r8a7795/Salvator-X HDMI output prototype
by Ulrich Hecht 26 Apr '22

26 Apr '22

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.

[Bug 53391] New: nouveau: wrong display output order

https://bugzilla.kernel.org/show_bug.cgi?id=53391 Summary: nouveau: wrong display output order Product: Drivers Version: 2.5 Kernel Version: 3.8-rc6 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri(a)kernel-bugs.osdl.org ReportedBy: stijn+bugs(a)linux-ipv6.be Regression: No My graphics card is a Gainward GTX480 (http://www.gainward.com/main/vgapro.php?id=238). It has 2 DVI outputs, and 1 mini HDMI output. The DVI outputs are numbered on the card, with DVI 1 being the closest to the PCIe slot, then DVI 2, and finally the mini HDMI. My primary (left) monitor, is connected to DVI 1, my secondary (right) monitor to DVI 2. When I boot the computer, the BIOS initializes and uses the monitor on DVI 1. Grub is displayed on the primary monitor, and the kernel initially outputs to the primary monitor as well. However, as soon as the nouveau module is loaded, the primary monitor goes to standby and the kernel now uses the secondary monitor (on DVI 2) as primary. When X starts (no Xorg.conf file), it is also displayed on the secondary monitor. When using either efifb, vesafb or uvesafb, the monitor on DVI 1 is always the primary monitor. X with nvidia.ko also uses DVI 1 as the primary display. Finally, when booting Windows, the startup screen is also displayed on the monitor connected to DVI 1. Here comes the weird part: when I am in X, and run xrandr, it does show 3 connected devices: DVI-I-1, DVI-I-2, and HDMI-1, with DVI-I-2 being the only active one. So it seems that in X, the output order is correct, but with nouveaufb the DVI connectors are swapped. I will attach the output of dmesg here. If anything else is needed, please let me know and I'll be happy to add it. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.

[PATCH v5 0/7] drm: add simpledrm driver
by David Herrmann 12 Mar '21

12 Mar '21

Hey On request of Noralf, I picked up the patches and prepared v5. Works fine with Xorg, if configured according to: https://lists.freedesktop.org/archives/dri-devel/2014-January/052777.html If anyone knows how to make Xorg pick it up dynamically without such a static configuration, please let me know. Thanks David David Herrmann (7): x86/sysfb: add support for 64bit EFI lfb_base x86/sysfb: fix lfb_size calculation of/platform: expose of_platform_device_destroy() video: add generic framebuffer eviction drm: switch to sysfb_evict_conflicts() drm: add SimpleDRM driver drm/simpledrm: add fbdev fallback support MAINTAINERS | 6 + arch/x86/kernel/sysfb_simplefb.c | 39 ++- drivers/gpu/drm/Kconfig | 3 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 24 +- drivers/gpu/drm/bochs/bochs_drv.c | 19 +- drivers/gpu/drm/i915/i915_drv.c | 73 +--- drivers/gpu/drm/mgag200/mgag200_drv.c | 27 +- drivers/gpu/drm/mgag200/mgag200_main.c | 9 - drivers/gpu/drm/nouveau/nouveau_drm.c | 33 +- drivers/gpu/drm/radeon/radeon_drv.c | 24 +- drivers/gpu/drm/simpledrm/Kconfig | 19 ++ drivers/gpu/drm/simpledrm/Makefile | 9 + drivers/gpu/drm/simpledrm/simpledrm.h | 91 +++++ drivers/gpu/drm/simpledrm/simpledrm_damage.c | 194 +++++++++++ drivers/gpu/drm/simpledrm/simpledrm_drv.c | 477 +++++++++++++++++++++++++++ drivers/gpu/drm/simpledrm/simpledrm_fbdev.c | 143 ++++++++ drivers/gpu/drm/simpledrm/simpledrm_gem.c | 109 ++++++ drivers/gpu/drm/simpledrm/simpledrm_kms.c | 270 +++++++++++++++ drivers/gpu/drm/simpledrm/simpledrm_of.c | 265 +++++++++++++++ drivers/gpu/drm/sun4i/sun4i_drv.c | 24 +- drivers/gpu/drm/vc4/vc4_drv.c | 25 +- drivers/gpu/drm/virtio/virtgpu_drm_bus.c | 24 +- drivers/of/platform.c | 35 +- drivers/video/Kconfig | 4 + drivers/video/Makefile | 1 + drivers/video/sysfb.c | 327 ++++++++++++++++++ include/linux/of_platform.h | 1 + include/linux/sysfb.h | 34 ++ 29 files changed, 2054 insertions(+), 256 deletions(-) create mode 100644 drivers/gpu/drm/simpledrm/Kconfig create mode 100644 drivers/gpu/drm/simpledrm/Makefile create mode 100644 drivers/gpu/drm/simpledrm/simpledrm.h create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_damage.c create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_drv.c create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_fbdev.c create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_gem.c create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_kms.c create mode 100644 drivers/gpu/drm/simpledrm/simpledrm_of.c create mode 100644 drivers/video/sysfb.c create mode 100644 include/linux/sysfb.h -- 2.9.3

[Bug 94061] New: [radeon - Kaveri] dpm works badly - much to high power consumption compared to catalyst

https://bugzilla.kernel.org/show_bug.cgi?id=94061 Bug ID: 94061 Summary: [radeon - Kaveri] dpm works badly - much to high power consumption compared to catalyst Product: Drivers Version: 2.5 Kernel Version: 3.14.x ... 3.19. 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: abcdmail(a)freenet.de Regression: No With all kernel versions >= 3.14 (I didn't test versions below), radeon / dpm consumes about 6 W more compared to catalyst in idle mode (X-server 1.15 / 1.16) with Kaveri graphics (AMD A10-7800 Radeon R7). Idle mode: Xorg runs (KDE 4.11.x), screen saver off, static screen, load: 0.0 If the screen is turned off by X, the power consumption finally reaches the same level as with catalyst. It's raising immediately again at the moment the screen is switched on again by X. Seams the lowest rate is never reached as long as even a static screen has to be drawn - but it should! -- You are receiving this mail because: You are watching the assignee of the bug.
