During this wait period one kworker is running full-time (though /proc/<pid>/stack has no useful data). Another kworker is waiting for IO to complete during that whole time period. Looking at drivers/scsi/qla2xxx/qla_os.c, fcport->retry_delay_timestamp has a special value of 0 though that 0 value forces system to wait when jiffies is very large value (e.g. 4294952605 - "negative" value when signed on 32bit systems).

This includes changing the IOCTL definitions, so it breaks compatibility with previous versions of the userspace. However, because the kernel was not officialy released yet, and this the first kernel that includes amdkfd, I assume I can still do that at this stage. - A couple of bug fixes for the non-HWS path (used for bring-ups and debugging purposes only). * tag 'amdkfd-fixes-2015-01-06' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: rewrite kfd_ioctl() according to drm_ioctl() drm/amdkfd: reformat IOCTL definitions to drm-style drm/amdkfd: Do copy_to/from_user in general kfd_ioctl() drm/amdkfd: unmap VMID<-->PASID when relesing VMID (non-HWS) drm/radeon: Assign VMID to PASID for IH in non-HWS mode drm/radeon: do not leave queue acquired if timeout happens in kgd_hqd_destroy() drm/amdkfd: Load mqd to hqd in non-HWS mode drm/amd: Fixing typos in kfd<->kgd interface

The patch defines an array of amdkfd_ioctls, which maps IOCTL definition to the ioctl function. The kfd_ioctl() uses that mapping to call the appropriate ioctl function, through a function pointer. This patch also declares a new typedef for the ioctl function pointer. v2: Renamed KFD_COMMAND_(START|END) to AMDKFD_...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If timeout happens, kgd_hqd_destroy() just returns -ETIME leaving queue acquired. It may cause a deadlock, so the patch proposes to release queue before return. Found by Linux Driver Verification project (linuxtesting.org).
