drm/amdkfd: Remove arbitrary timeout for hmm_range_fault
On system with khugepaged enabled and user cases with THP buffer, the hmm_range_fault may takes > 15 seconds to return -EBUSY, the arbitrary timeout value is not accurate, cause memory allocation failure. Remove the arbitrary timeout value, return EAGAIN to application if hmm_range_fault return EBUSY, then userspace libdrm and Thunk will call ioctl again. Change EAGAIN to debug message as this is not error. Signed-off-by: Philip Yang <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
