Those parameters have given me up to 144 minutes before experiencing the freeze, a huge record compared to the previous 90 minutes! They are: amdgpu.prim_buf_per_se=16 amdgpu.pos_buf_per_se=16 amdgpu.cntl_sb_buf_per_se=16 amdgpu.param_buf_per_se=16 By default, all 4 of those settings are set to 0 by the system. Setting them to 16 has, at least during one test case, reduced the problem to 1/5 of its previous frequency. The descriptions of the variables are: parm: prim_buf_per_se:the size of Primitive Buffer per Shader Engine (default depending on gfx) (int) parm: pos_buf_per_se:the size of Position Buffer per Shader Engine (default depending on gfx) (int) parm: cntl_sb_buf_per_se:the size of Control Sideband per Shader Engine (default depending on gfx) (int) parm: param_buf_per_se:the size of Off-Chip Pramater Cache per Shader Engine (default depending on gfx) (int) I will continue trying different values and seeing how tweaking them changes the issue. Please let me know what you think.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
