Bug ID: 89241 Summary: A8-6410 APU with integrated R5 Mullins + dedicated R5 M240 Hainan graphics switching not working Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: linux5@secure-mail.biz

Switching graphics between the A8-6410 APU with integrated R5 Mullins + dedicated R5 M240 Hainan is not working(HP 355 G2 notebook). I think it's because the dedicated gpu for some reason can just not be activated, because "/sys/kernel/debug/vgaswitcheroo/switch" and the Radeon Profile tool show two gpus, but changing the gpu state from "off" to something else within Radeon Profile doesn't work for the dedicated one. I tried the gearsongallium livecd with very recent drivers/Xorg/etc.

Versions included in the gearsongallium livedvd i tested: Mesa-git – 10.5_git2015.02.04 Kernel – 3.19-rc6 libdrm – 2.4.99_git2015.01.22 Mesa-demos – 9.1.0_git2014.07.06 xorg-server – 1.16.99.9 xf86-video-ati – 7.99.99_2015.01.15

I also tried in Kubuntu 14.10 to switch with DRI_PRIME=1. If i do that i get corrupt window and lower fps than with integrated gpu with es2gears. However "DRI_PRIME=1 glxinfo" says it's using the dedicated gpu. In gearsongallium i get the same output with or without "DRI_PRIME=1 glxinfo" so it seems to not switch at all with recent drivers/Xorg/etc.

I can also post Xorg log and dmesg output, but i couldn't spot anything unusual there looking quickly through it. However "dmesg|grep -i vga" might be important: $ dmesg |grep -i vga [ 1.069056] vgaarb: setting as boot device: PCI:0000:00:01.0 [ 1.069061] vgaarb: device added: PCI:0000:00:01.0,decodes=io+mem,owns=io+mem,locks=none [ 1.069077] vgaarb: loaded [ 1.069080] vgaarb: bridge control possible 0000:00:01.0 [ 1.763179] fb0: EFI VGA frame buffer device [ 2.029145] ACPI: Video Device [VGA] (multi-head: yes rom: no post: no) [ 2.115398] VGA switcheroo: detected switching method _SB_.PCI0.VGA_.ATPX handle [ 2.191102] ACPI: Video Device [VGA1] (multi-head: yes rom: no post: no) [ 2.255714] fb: switching to radeondrmfb from EFI VGA [ 2.440405] [drm] VGA-1 [ 2.527423] vga_switcheroo: enabled
