Bug ID: 99049 Summary: Machine freeze when clock are set to defaults 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: ls@maxux.net

My laptop contains theses cards: ---- 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330] (rev 81) ----

Under Gentoo, I enabled radeon and radeonsi as videos cards, everything looks fine. According to xrandr, I have providers: ---- Provider 0: id: 0x76 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 0 name:Intel Provider 1: id: 0x4f cap: 0xd, Source Output, Source Offload, Sink Offload crtcs: 0 outputs: 0 associated providers: 0 name:HAINAN @ pci:0000:01:00.0 ----

I found on the internet that DPM could cause issue, I tried: radeon.runpm=0 radeon.dpm=0 (see below)

Using theses settings, I don't have any freeze when I try to use the Radeon Card (using DRI_PRIME=1), but I found that everything was slow. I checked, and I saw: --- cat /sys/class/drm/card1/device/power_method profile

cat /sys/class/drm/card1/device/power_profile default

cat /sys/kernel/debug/dri/65/radeon_pm_info default engine clock: 1070000 kHz current engine clock: 299990 kHz default memory clock: 900000 kHz current memory clock: 298990 kHz voltage: 1150 mV PCIE lanes: 4 ---

The card is running in low profile by default, don't know why. Setting power_profile to high, mid or low doesn't change anything, but if I set power_profile back to default again, the clock is set to full speed.

When clock is set to full speed, my system freeze if I try to run any 3D application (glxgears or a game using wine). Here is the dmesg log: --- radeon 0000:01:00.0: ring 0 stalled for more than 10436msec radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000014f4 last fence id 0x00000000000014f6 on ring 0) radeon 0000:01:00.0: Saved 49 dwords of commands on ring 0. radeon 0000:01:00.0: GPU softreset: 0x00000049 radeon 0000:01:00.0: GRBM_STATUS = 0xE5D04028 radeon 0000:01:00.0: GRBM_STATUS_SE0 = 0xEE400000 radeon 0000:01:00.0: GRBM_STATUS_SE1 = 0x00000006 radeon 0000:01:00.0: SRBM_STATUS = 0x200000C0 radeon 0000:01:00.0: SRBM_STATUS2 = 0x00000000 radeon 0000:01:00.0: R_008674_CP_STALLED_STAT1 = 0x00000000 radeon 0000:01:00.0: R_008678_CP_STALLED_STAT2 = 0x00018000 radeon 0000:01:00.0: R_00867C_CP_BUSY_STAT = 0x00008000 radeon 0000:01:00.0: R_008680_CP_STAT = 0x80030243 radeon 0000:01:00.0: R_00D034_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: R_00D834_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000 radeon 0000:01:00.0: GRBM_SOFT_RESET=0x0000DDFF radeon 0000:01:00.0: SRBM_SOFT_RESET=0x00000100 radeon 0000:01:00.0: GRBM_STATUS = 0x00003028 radeon 0000:01:00.0: GRBM_STATUS_SE0 = 0x00000006 radeon 0000:01:00.0: GRBM_STATUS_SE1 = 0x00000006 radeon 0000:01:00.0: SRBM_STATUS = 0x200000C0 radeon 0000:01:00.0: SRBM_STATUS2 = 0x00000000 radeon 0000:01:00.0: R_008674_CP_STALLED_STAT1 = 0x00000000 radeon 0000:01:00.0: R_008678_CP_STALLED_STAT2 = 0x00000000 radeon 0000:01:00.0: R_00867C_CP_BUSY_STAT = 0x00000000 radeon 0000:01:00.0: R_008680_CP_STAT = 0x00000000 radeon 0000:01:00.0: R_00D034_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: R_00D834_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: GPU reset succeeded, trying to resume [drm] probing gen 2 caps for device 8086:9d10 = 1724843/e [drm] PCIE gen 3 link speeds already enabled [drm] PCIE GART of 2048M enabled (table at 0x0000000000040000). radeon 0000:01:00.0: WB enabled radeon 0000:01:00.0: fence driver on ring 0 use gpu addr 0x0000000100000c00 and cpu addr 0xffff88046c66dc00 radeon 0000:01:00.0: fence driver on ring 1 use gpu addr 0x0000000100000c04 and cpu addr 0xffff88046c66dc04 radeon 0000:01:00.0: fence driver on ring 2 use gpu addr 0x0000000100000c08 and cpu addr 0xffff88046c66dc08 radeon 0000:01:00.0: fence driver on ring 3 use gpu addr 0x0000000100000c0c and cpu addr 0xffff88046c66dc0c radeon 0000:01:00.0: fence driver on ring 4 use gpu addr 0x0000000100000c10 and cpu addr 0xffff88046c66dc10 [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD) [drm:si_resume [radeon]] *ERROR* si startup failed on resume ---

I found out with theses steps that, if I don't set dpm=0, I hit exactly the same issue, I guess using DPM the clock is set to high when the card is used and it crash. When the card is stuck on that loop, I need to reset the machine (but network still works).

I'm using mesa-13.0.2 with a 4.7.6 kernel, I have the same issue using mesa 12.0.1
