Hi Oded, - pipe_hpd_addr = dqm->pipelines_addr + i * CIK_HPD_EOP_BYTES; + pipe_hpd_addr = dqm->pipelines_addr + inx * CIK_HPD_EOP_BYTES; I think 'i' should still be used here, because it is the real index in the buffer Besides, for the code below in init_scheduler(), it looks like the KFD_DQM_FIRST_PIPE is not correct, and we probably need to use get_first_pipe(dqm) instead. retval = init_pipelines(dqm, get_pipes_num(dqm), KFD_DQM_FIRST_PIPE); Regards, Jammy -----Original Message----- From: dri-devel [mailto:dri-devel-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Gabbay, Oded Sent: Thursday, January 22, 2015 5:07 PM To: dri-devel@xxxxxxxxxxxxxxxxxxxxx Subject: [PATCH] drm/amdkfd: Fix bug in pipelines initialization This patch fixes a bug when calling to init_pipeline() interface. The index that was passed to that function didn't take into account the first_pipe value, which represents the first pipe index that is under amdkfd's responsibility.
