drm/amdkfd: Fix kernel-queue wrapping bugs

2017-09-20T22:10:21+00:00

Avoid intermediate negative numbers when doing calculations with a mix
of signed and unsigned variables where implicit conversions can lead
to unexpected results.

When kernel queue buffer wraps around to 0, we need to check that rptr
won't be overwritten by the new packet.

drm/amdkfd: check for null dev to avoid a null pointer dereference

2017-09-08T14:13:33+00:00

The call to kfd_device_by_id can potentially return null, so check that
dev is null and return with -EINVAL to avoid a null pointer dereference.

drm/amdkfd: pass queue's mqd when destroying mqd

2017-09-02T12:00:25+00:00

In VI, the destroy mqd function needs to inquire fields present in the mqd
structure. That's why we need to pass it to that function instead of NULL.

makes memset redundant.

drm/amdkfd: Update PM4 packet headers

2017-08-16T03:00:15+00:00

To match current firmware. The map process packet has been extended
to support scratch. This is a non-backwards compatible change and
it's about two years old. So no point keeping the old version around
conditionally.
