https://bugzilla.kernel.org/show_bug.cgi?id=117131 Bug ID: 117131 Summary: vga_switcheroo does not switch IGP -> DIS ( IGP == i915 , DIS == radeon ) Product: Drivers Version: 2.5 Kernel Version: 4.5.0 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: jason.vas.dias@xxxxxxxxx Regression: No I have built the latest GIT tag of : git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git (v4.5.0) and after much experimentation I have concluded that the vga_switcheroo switch operation just isn't working correctly . I have VGA hardware : $ lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

I have both the i915 and radeon drivers and related DRM drivers built-in - this should show the relevant configs, when in kernel build directory : $ egrep -i 'radeon|drm|i915' .config | egrep -v '^#' CONFIG_DRM=y CONFIG_DRM_MIPI_DSI=y CONFIG_DRM_KMS_HELPER=y CONFIG_DRM_KMS_FB_HELPER=y CONFIG_DRM_FBDEV_EMULATION=y CONFIG_DRM_LOAD_EDID_FIRMWARE=y CONFIG_DRM_TTM=y CONFIG_DRM_RADEON=y CONFIG_DRM_RADEON_USERPTR=y CONFIG_DRM_AMDGPU=y CONFIG_DRM_AMDGPU_CIK=y CONFIG_DRM_AMDGPU_USERPTR=y CONFIG_DRM_AMD_POWERPLAY=y CONFIG_DRM_I915=y CONFIG_DRM_VMWGFX=m CONFIG_DRM_VMWGFX_FBCON=y CONFIG_DRM_GMA500=y CONFIG_DRM_GMA600=y CONFIG_DRM_GMA3600=y CONFIG_DRM_UDL=m CONFIG_DRM_CIRRUS_QEMU=m CONFIG_DRM_QXL=y CONFIG_DRM_BOCHS=y CONFIG_DRM_VIRTIO_GPU=m CONFIG_DRM_PANEL=y CONFIG_DRM_PANEL_SIMPLE=m CONFIG_DRM_PANEL_SAMSUNG_LD9040=m CONFIG_DRM_PANEL_LG_LG4573=m CONFIG_DRM_PANEL_PANASONIC_VVX10F034N00=m CONFIG_DRM_PANEL_SAMSUNG_S6E8AA0=m CONFIG_DRM_PANEL_SHARP_LQ101R1SX01=m CONFIG_DRM_PANEL_SHARP_LS043T1LE01=m CONFIG_DRM_BRIDGE=y CONFIG_DRM_NXP_PTN3460=m CONFIG_DRM_PARADE_PS8622=m CONFIG_FB_RADEON=y CONFIG_FB_RADEON_I2C=y CONFIG_FB_RADEON_BACKLIGHT=y CONFIG_FB_RADEON_DEBUG=y CONFIG_SND_HDA_I915=y ( I try to make the kernel not need any modules in order to boot into graphics mode ). But I can't even get the card to go into graphics mode . I have tried using all combinations of related kernel boot parameters: radeon.modeset=1 \ video=1920x1080@60e | video=radeon:1920x1080@60e \ fbcon=map:01 \ drm_kms_helper.edid_firmware=edid/1920x1080.bin - I've tried these individually on their own, or all together, or none of them at all, and various combinations of them, but no combination of them allow the framebuffers to be controlled by the radeon card . When the system comes up with a getty login session on a terminal, $ cat /sys/kernel/debug/vga_switcheroo/switch says: 0:DIS: :DynOff:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0 At first I tried : $ echo ON > /sys/kernel/debug/vga_switcheroo/switch to turn the non-selected FB on - right ? But this has no effect - contents of the switch are as before. Then trying to do: $ echo DIS > /sys/kernel/debug/vga_switcheroo makes the screen go blank for @ 60 seconds - pressing VT-Switch keystrokes have no effect; eventually, after about 1 minute, no matter what key I press, the terminal session is displayed again, and I see lots of DMESGs have been logged, as shown below. The following DMESGs were collected in my logs after doing : $ dmesg -c >/var/log/dmesg-4.5.0-boot.log $ { echo ON >/sys/kernel/debug/vgaswitcheroo/switch; echo DDIS >/sys/kernel/debug/vgaswitcheroo/switch; Xorg -logverbose 7 -verbose 7 :0 vt04 || { echo ON >/sys/kernel/debug/vgaswitcheroo/switch; echo IGP >/sys/kernel/debug/vgaswitcheroo/switch; } ; } & ( sleep 3; cat /sys/kernel/debug/vgaswitcheroo/switch > ~/vga_switcheroo_switch_last; xterm & ) ) Then waiting for @ 60 seconds, and pressing <CTRL>+<ALT>+<F1> to switch back to VT #1. The contents of ~/vga_switcheroo_switch_last (when xterm is run) are : 0:DIS:+:DynOff:0000:01:00.0 1:IGD: :Off:0000:00:02.0 ( How can an FB not be in the Pwr state and be connected ? ) Then once the screen comes back after @ 1 minute hang, I doing $ dmesg 2>&1 | tee /var/log/dmesg-4.5.0-drm-problem.log would show : [ 274.182788] i915: switched off [ 275.466825] ------------[ cut here ]------------ [ 275.466854] WARNING: CPU: 0 PID: 4403 at drivers/gpu/drm/i915/intel_display.c:9475 hsw_enable_pc8+0x4f6/0x750() [ 275.466864] Power well on [ 275.466869] Modules linked in: [ 275.466881] CPU: 0 PID: 4403 Comm: bash Tainted: G W 4.5.0 #3 [ 275.466889] Hardware name: Notebook P15SM /P15SM , BIOS 4.6.5 12/26/2013 [ 275.466901] 0000000000000286 00000000ddcb0b11 ffff8804179dfc08 ffffffff814d9550 [ 275.466916] ffff8804179dfc50 ffffffff821be4f0 ffff8804179dfc40 ffffffff810608b2 [ 275.466929] ffff8800c89c0000 ffff880415003cf8 ffff880415003d08 ffff880415003800 [ 275.466943] Call Trace: [ 275.466957] [<ffffffff814d9550>] dump_stack+0x99/0xd9 [ 275.466972] [<ffffffff810608b2>] warn_slowpath_common+0x82/0xc0 [ 275.466982] [<ffffffff8106094c>] warn_slowpath_fmt+0x5c/0x80 [ 275.466993] [<ffffffff818710e6>] hsw_enable_pc8+0x4f6/0x750 [ 275.467007] [<ffffffff817efd8e>] intel_suspend_complete+0xee/0x720 [ 275.467016] [<ffffffff817f03fd>] i915_drm_suspend_late+0x3d/0xe0 [ 275.467026] [<ffffffff817f04ea>] i915_suspend_switcheroo+0x4a/0xb0 [ 275.467039] [<ffffffff8173d817>] ? radeon_atpx_switchto+0x197/0x1b0 [ 275.467053] [<ffffffff818adfc9>] i915_switcheroo_set_state+0x39/0x80 [ 275.467065] [<ffffffff818db1b8>] vga_switchoff.part.2+0x18/0x40 [ 275.467074] [<ffffffff818db2e4>] vga_switchto_stage2+0x104/0x110 [ 275.467083] [<ffffffff818da459>] ? vga_set_default_device+0x29/0x40 [ 275.467092] [<ffffffff818db689>] vga_switcheroo_debugfs_write+0x2e9/0x390 [ 275.467107] [<ffffffff811f7115>] ? do_filp_open+0xa5/0x100 [ 275.467118] [<ffffffff811e6507>] __vfs_write+0x37/0x120 [ 275.467129] [<ffffffff810850e5>] ? preempt_count_sub+0xa5/0xf0 [ 275.467140] [<ffffffff810a7626>] ? update_fast_ctr+0x46/0x70 [ 275.467149] [<ffffffff810a7697>] ? percpu_down_read+0x17/0x50 [ 275.467158] [<ffffffff811e6d89>] vfs_write+0xa9/0x1a0 [ 275.467168] [<ffffffff811e7998>] SyS_write+0x58/0xd0 [ 275.467179] [<ffffffff812050b3>] ? __close_fd+0xa3/0xd0 [ 275.467194] [<ffffffff81dd89ae>] entry_SYSCALL_64_fastpath+0x12/0x6d [ 275.467218] ---[ end trace b1cc3f6a5140ca17 ]--- [ 275.467229] ------------[ cut here ]------------ [ 275.467241] WARNING: CPU: 0 PID: 4403 at drivers/gpu/drm/i915/intel_display.c:9486 hsw_enable_pc8+0x574/0x750() [ 275.467250] PCH PWM1 enabled [ 275.467254] Modules linked in: [ 275.467323] CPU: 0 PID: 4403 Comm: bash Tainted: G W 4.5.0 #3 [ 275.467337] Hardware name: Notebook P15SM /P15SM , BIOS 4.6.5 12/26/2013 [ 275.467347] 0000000000000286 00000000ddcb0b11 ffff8804179dfc08 ffffffff814d9550 [ 275.467361] ffff8804179dfc50 ffffffff821be4f0 ffff8804179dfc40 ffffffff810608b2 [ 275.467373] ffff8800c89c0000 ffff880415003cf8 ffff880415003d08 ffff880415003800 [ 275.467386] Call Trace: [ 275.467393] [<ffffffff814d9550>] dump_stack+0x99/0xd9 [ 275.467403] [<ffffffff810608b2>] warn_slowpath_common+0x82/0xc0 [ 275.467413] [<ffffffff8106094c>] warn_slowpath_fmt+0x5c/0x80 [ 275.467424] [<ffffffff81871164>] hsw_enable_pc8+0x574/0x750 [ 275.467433] [<ffffffff817efd8e>] intel_suspend_complete+0xee/0x720 [ 275.467443] [<ffffffff817f03fd>] i915_drm_suspend_late+0x3d/0xe0 [ 275.467452] [<ffffffff817f04ea>] i915_suspend_switcheroo+0x4a/0xb0 [ 275.467463] [<ffffffff8173d817>] ? radeon_atpx_switchto+0x197/0x1b0 [ 275.467473] [<ffffffff818adfc9>] i915_switcheroo_set_state+0x39/0x80 [ 275.467483] [<ffffffff818db1b8>] vga_switchoff.part.2+0x18/0x40 [ 275.467492] [<ffffffff818db2e4>] vga_switchto_stage2+0x104/0x110 [ 275.467500] [<ffffffff818da459>] ? vga_set_default_device+0x29/0x40 [ 275.467510] [<ffffffff818db689>] vga_switcheroo_debugfs_write+0x2e9/0x390 [ 275.467521] [<ffffffff811f7115>] ? do_filp_open+0xa5/0x100 [ 275.467531] [<ffffffff811e6507>] __vfs_write+0x37/0x120 [ 275.467539] [<ffffffff810850e5>] ? preempt_count_sub+0xa5/0xf0 [ 275.467548] [<ffffffff810a7626>] ? update_fast_ctr+0x46/0x70 [ 275.467556] [<ffffffff810a7697>] ? percpu_down_read+0x17/0x50 [ 275.467566] [<ffffffff811e6d89>] vfs_write+0xa9/0x1a0 [ 275.467576] [<ffffffff811e7998>] SyS_write+0x58/0xd0 [ 275.467585] [<ffffffff812050b3>] ? __close_fd+0xa3/0xd0 [ 275.467596] [<ffffffff81dd89ae>] entry_SYSCALL_64_fastpath+0x12/0x6d [ 275.467605] ---[ end trace b1cc3f6a5140ca18 ]--- [ 276.000207] [drm] probing gen 2 caps for device 8086:c01 = 261ad03/e [ 276.000213] [drm] PCIE gen 3 link speeds already enabled [ 276.003659] [drm] PCIE GART of 2048M enabled (table at 0x00000000002E8000).
