That just means you are again running with GPU VM update mode set to use SDMA. Which is seen in you dmesg (amdgpu.vm_update_mode=0) , so are again experiencing the original issue of SDMA hang. Please use amdgpu.vm_update_mode=3 to get back to VM_FAULTs issue. > > amdgpu_cs:0-806 [012] .... 1787.493126: amdgpu_vm_bo_cs: > soffs=00001001a0, eoffs=00001001b9, flags=70 > amdgpu_cs:0-806 [012] .... 1787.493127: amdgpu_vm_bo_cs: > soffs=0000100200, eoffs=00001021e0, flags=70 > amdgpu_cs:0-806 [012] .... 1787.493127: amdgpu_vm_bo_cs: > soffs=0000102200, eoffs=00001041e0, flags=70 > amdgpu_cs:0-806 [012] .... 1787.493129: amdgpu_vm_bo_cs: > soffs=000010c1e0, eoffs=000010c2e1, flags=70 > amdgpu_cs:0-806 [012] .... 1787.493131: drm_sched_job: > entity=00000000406345a7, id=10239, fence=000000007a120377, ring=gfx, job > count:8, hw job count:0 > > And later in the file you can find: > ------------------------------------------------------ > crash detected! > > executing umr -O halt_waves -wa > No active waves! > > executing umr -O verbose -R gfx[.] > > polaris11.gfx.rptr == 512 > polaris11.gfx.wptr == 512 > polaris11.gfx.drv_wptr == 512 > polaris11.gfx.ring[ 481] == 0xffff1000 ... > polaris11.gfx.ring[ 482] == 0xffff1000 ... > polaris11.gfx.ring[ 483] == 0xffff1000 ... > polaris11.gfx.ring[ 484] == 0xffff1000 ... > polaris11.gfx.ring[ 485] == 0xffff1000 ... > polaris11.gfx.ring[ 486] == 0xffff1000 ... > polaris11.gfx.ring[ 487] == 0xffff1000 ... > polaris11.gfx.ring[ 488] == 0xffff1000 ... > polaris11.gfx.ring[ 489] == 0xffff1000 ... > polaris11.gfx.ring[ 490] == 0xffff1000 ... > polaris11.gfx.ring[ 491] == 0xffff1000 ... > polaris11.gfx.ring[ 492] == 0xffff1000 ... > polaris11.gfx.ring[ 493] == 0xffff1000 ... > polaris11.gfx.ring[ 494] == 0xffff1000 ... > polaris11.gfx.ring[ 495] == 0xffff1000 ... > polaris11.gfx.ring[ 496] == 0xffff1000 ... > polaris11.gfx.ring[ 497] == 0xffff1000 ... > polaris11.gfx.ring[ 498] == 0xffff1000 ... > polaris11.gfx.ring[ 499] == 0xffff1000 ... > polaris11.gfx.ring[ 500] == 0xffff1000 ... > polaris11.gfx.ring[ 501] == 0xffff1000 ... > polaris11.gfx.ring[ 502] == 0xffff1000 ... > polaris11.gfx.ring[ 503] == 0xffff1000 ... > polaris11.gfx.ring[ 504] == 0xffff1000 ... > polaris11.gfx.ring[ 505] == 0xffff1000 ... > polaris11.gfx.ring[ 506] == 0xffff1000 ... > polaris11.gfx.ring[ 507] == 0xffff1000 ... > polaris11.gfx.ring[ 508] == 0xffff1000 ... > polaris11.gfx.ring[ 509] == 0xffff1000 ... > polaris11.gfx.ring[ 510] == 0xffff1000 ... > polaris11.gfx.ring[ 511] == 0xffff1000 ... > polaris11.gfx.ring[ 512] == 0xc0032200 rwD > > > trying to get ADR from dmesg output for 'umr -O verbose -vm ...' > trying to get VMID from dmesg output for 'umr -O verbose -vm ...' > > done after crash. > ------------------------------------------- > > So even without GPU reset, still no "waves".
