drm/amdgpu: fix DP mode validation

2016-05-19T01:35:15+00:00

commit c47b9e0944e483309d66c807d650ac8b8ceafb57 upstream.

Switch the order of the loops to walk the rates on the top
so we exhaust all DP 1.1 rate/lane combinations before trying
DP 1.2 rate/lane combos.

This avoids selecting rates that are supported by the monitor,
but not the connector leading to valid modes getting rejected.

drm/amdgpu: set metadata pointer to NULL after freeing.

2016-05-11T09:21:38+00:00

commit 0092d3edcb23fcdb8cbe4159ba94a534290ff982 upstream.

Without this there was a double free of the metadata,
which ended up freeing the fd table for me here, and taking
out the machine more often than not.

I reproduced with X.org + modesetting DDX + latest llvm/mesa,
also required using dri3.

either -EINVAL or uninitialized.

drm/amdgpu: fix regression on CIK (v2)

2016-05-04T21:49:05+00:00

This fix was written against drm-next, but when it was
backported to 4.5 as a stable fix, the driver internal
structure change was missed.  Fix that up here to avoid
a hang due to waiting for the wrong sequence number.
