Summary: r600g fails shader, tries to run with failed shader, freezes. Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: equinox-freedesktopbugs@diac24.net
when trying to create a character in EVE Online, after the first few screens I encounter multiple shaders that cannot be translated from TGSI. The error message printed is: "r600_pipe_shader_create - translation from TGSI failed !"
I've traced this down to: ^ check_and_set_bank_swizzle (-1) from ^ r600_bc_add_alu_type from ^ r600_shader_from_tgsi from ^ r600_pipe_shader_create (opcode: 0x09 "ADD")
Problematically, the application continues running after that, complains about "missing shader" and finally - a whole few seconds later, continuing to draw the loading animation - freezes the GFX card:
[ 4996.188064] radeon 0000:03:00.0: GPU lockup CP stall for more than 10000msec [ 4996.188072] ------------[ cut here ]------------ [ 4996.188147] WARNING: at drivers/gpu/drm/radeon/radeon_fence.c:246 radeon_fence_wait+0x21c/0x2bb [radeon]() [ 4996.188160] GPU lockup (waiting for 0x00011BDD last fence id 0x00011BD9)
after that I have to kill my X server and restart it.
(So this is basically two bugs, the shader failing, and the driver trying to use a failed shader I assume - though the lockup might also be unrelated)
