https://bugzilla.kernel.org/show_bug.cgi?id=201843 Bug ID: 201843 Summary: Micro-stuttering each second on amdgpu only on 2560x1440 Product: Drivers Version: 2.5 Kernel Version: 4.19.2-arch1-1-ARCH Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: kairllur@xxxxxxxxx Regression: No Created attachment 279797 --> https://bugzilla.kernel.org/attachment.cgi?id=279797&action=edit GPU stutter visualized - DOOM Hello, it's me again. I notice that in many games if I play on my native screen resolution (2560x1440) the games always have micro-stutter. If I switch to 1920x1080 it is resolved. Facts: - The micro-stutter doesn't show up right after launch, you have to play a bit for it to start - If I set power_dpm_force_performance_level to low and then to high/auto again the micro-stutter disappears and then gradually accumulates again - I always play with window compositing disabled (KDE) Hardware info: System: Kernel: 4.19.2-arch1-1-ARCH x86_64 bits: 64 compiler: gcc v: 8.2.1 Desktop: KDE Plasma 5.14.4 Distro: Arch Linux Machine: Type: Desktop Mobo: ASRock model: X370 Gaming K4 UEFI: American Megatrends v: P4.70 date: 04/18/2018 CPU: Topology: 8-Core model: AMD Ryzen 7 1700X bits: 64 type: MT MCP arch: Zen rev: 1 L2 cache: 4096 KiB flags: lm nx pae sse sse2 sse3 sse4_1 sse4_2 sse4a ssse3 svm bogomips: 108626 Speed: 1960 MHz min/max: 2200/3400 MHz Core speeds (MHz): 1: 1943 2: 1966 3: 3270 4: 3224 5: 2247 6: 2317 7: 3084 8: 3224 9: 3447 10: 3390 11: 2669 12: 2669 13: 3194 14: 3067 15: 3220 16: 3329 Graphics: Device-1: Advanced Micro Devices [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X] driver: amdgpu v: kernel bus ID: 26:00.0 Display: x11 server: X.Org 1.20.3 driver: modesetting unloaded: fbdev,vesa resolution: 2560x1440~60Hz OpenGL: renderer: AMD Radeon RX 480 Graphics (POLARIS10 DRM 3.27.0 4.19.2-arch1-1-ARCH LLVM 7.0.0) v: 4.5 Mesa 18.2.5 direct render: Yes Info: Memory: 31.41 GiB used: 12.89 GiB (41.0%) Misc: Total Samples: 76167 (6.493KHz) amdgpu:amdgpu_mm_rreg: 1527 (1527 samples, 2% of total, 130.2Hz) amdgpu:amdgpu_mm_wreg: 97 (97 samples, 0.127% of total, 8.269Hz) WARNING: Sampling frequency below 100Hz amdgpu:amdgpu_iv: 1520 (1520 samples, 2% of total, 129.6Hz) amdgpu:amdgpu_cs: 2426 (2426 samples, 3.19% of total, 206.8Hz) amdgpu:amdgpu_cs_ioctl: 1190 (1190 samples, 1.56% of total, 101.4Hz) amdgpu:amdgpu_vm_bo_mapping: 1.297E+04 (1.297E+04 samples, 17% of total, 1.105KHz) amdgpu:amdgpu_vm_bo_cs: 1.399E+04 (1.399E+04 samples, 18.4% of total, 1.193KHz) amdgpu:amdgpu_bo_list_set: 4.126E+04 (4.126E+04 samples, 54.2% of total, 3.518KHz) amdgpu:amdgpu_cs_bo_status: 1188 (1188 samples, 1.56% of total, 101.3Hz) -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
