drm/amdkfd: destroy dbgmgr in notifier release

2016-07-27T16:47:34+00:00

commit bc4755a4bd1845ef6e88ac8c62f12e05bb530256 upstream.

amdkfd need to destroy the debug manager in case amdkfd's notifier
function is called before the unbind function, because in that case,
the unbind function will exit without destroying debug manager.

drm/amdkfd: unbind only existing processes

2016-07-27T16:47:33+00:00

commit 121b78e679ee3ffab780115e260b2775d0cc1f73 upstream.

When unbinding a process from a device (initiated by amd_iommu_v2), the
driver needs to make sure that process still exists in the process table.
There is a possibility that amdkfd's own notifier handler -
kfd_process_notifier_release() - was called before the unbind function
and it already removed the process from the process table.

v2:
Because there can be only one process with the specified pasid, and
because *p can't be NULL inside the hash_for_each_rcu macro, it is more
reasonable to just put the whole code inside the if statement that
compares the pasid value. That way, when we exit hash_for_each_rcu, we
simply exit the function as well.

drm/amdgpu: Fix hdmi deep color support.

2016-06-08T01:14:36+00:00

commit 9d746ab68163d642dae13756b2b3145b2e38cb65 upstream.

When porting the hdmi deep color detection code from
radeon-kms to amdgpu-kms apparently some kind of
copy and paste error happened, attaching an else
branch to the wrong if statement.

The result is that hdmi deep color mode is always
disabled, regardless of gpu and display capabilities and
user wishes, as the code mistakenly thinks that the display
doesn't provide the required max_tmds_clock limit and falls
back to 8 bpc.

This patch fixes deep color support, as tested on a
R9 380 Tonga Pro + suitable display, and should be
backported to all kernels with amdgpu-kms support.

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

2016-05-11T09:21:22+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)

2016-05-04T21:48:46+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.
