drm/amdkfd: allow split HQD on per-queue granularity v5

2017-05-31T20:48:54+00:00

Update the KGD to KFD interface to allow sharing pipes with queue
granularity instead of pipe granularity.

This allows for more interesting pipe/queue splits.

v2: fix overflow check for res.queue_mask
v3: fix shift overflow when setting res.queue_mask
v4: fix comment in is_pipeline_enabled()
v5: clamp res.queue_mask to the first MEC only

drm/amdkfd: Clean up inline handling

2016-06-21T19:32:52+00:00

- inline functions need to be static inline, otherwise gcc can opt to
  not inline and the linker gets unhappy.
- no forward decls for inline functions, just include the right headers.

drm/amdkfd: Add static user-mode queues support

2015-06-03T08:32:28+00:00

This patch adds support for static user-mode queues in QCM.
Queues which are designated as static can NOT be preempted by
the CP microcode when it is executing its scheduling algorithm.

This is needed for supporting the debugger feature, because we
can't allow the CP to preempt queues which are currently being debugged.

The number of queues that can be designated as static is limited by the
number of HQDs (Hardware Queue Descriptors).

drm/amdkfd: Use new struct for asic specific ops

2015-05-19T09:13:38+00:00

This patch creates a new structure for asic specific operations, instead
of using the existing structure of operations.

This is done to make the code flow more logic, readable and maintainable.

The change is done only to the device queue manager module at this point.

drm/amdkfd: don't set get_pipes_num() as inline

2015-02-23T08:48:02+00:00

get_pipes_num() calls BUG_ON so we can't set it as inline because it produces a
warning as BUG_ON() uses static variables when it is expanded.

drm/amdkfd: Initialize only amdkfd's assigned pipelines

2015-02-23T08:47:56+00:00

This patch fixes a bug in the initialization of the pipelines. The
init_pipelines() function was called with a constant value of 0 in the
first_pipe argument. This is an error because amdkfd doesn't handle pipe 0.

The correct way is to pass the value that get_first_pipe() returns as the
argument for first_pipe.

This bug appeared in 3.19 (first version with amdkfd) and it causes around 15%
drop in CPU performance of Kaveri (A10-7850).

v2: Don't set get_first_pipe() as inline because it calls BUG_ON()

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into drm-next

2015-01-29T01:45:31+00:00

This backmerges drm-fixes into drm-next mainly for the amdkfd
stuff, I'm not 100% confident, but it builds and the amdkfd
folks can fix anything up.
