drm/amdkfd: Clamp EOP queue size correctly on Gfx8

2017-08-16T03:00:14+00:00

Gfx8 HW incorrectly clamps CP_HQD_EOP_CONTROL.EOP_SIZE, which can lead to scheduling deadlock due to SE EOP done counter overflow. Enforce a EOP queue size limit which prevents the CP from sending more than 0xFF events at a time.

In most cases, BUG_ONs can be replaced with WARN_ON with an error return. In some void functions just turn them into a WARN_ON and possibly an early exit. v2: * Cleaned up error handling in pm_send_unmap_queue * Removed redundant WARN_ON in kfd_process_destroy_delayed Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay

drm/amdkfd: Allocate gtt_sa_bitmap in long units

2017-08-16T03:00:11+00:00

gtt_sa_bitmap is accessed by bitmap functions, which operate on longs. Therefore the array should be allocated in long units. Also round up in case the number of bits is not a multiple of BITS_PER_LONG. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Remove BUG_ONs for NULL pointer arguments

2017-08-16T03:00:09+00:00

Remove BUG_ONs that check for NULL pointer arguments that are dereferenced in the same function. Dereferencing the NULL pointer will generate a BUG anyway, so the explicit check is redundant and unnecessary overhead. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay
