drm/amdkfd: rewrite kfd_ioctl() according to drm_ioctl()

2015-01-06T17:44:36+00:00

This patch changes kfd_ioctl() to be very similar to drm_ioctl().

The patch defines an array of amdkfd_ioctls, which maps IOCTL definition to the
ioctl function.

The kfd_ioctl() uses that mapping to call the appropriate ioctl function,
through a function pointer.

This patch also declares a new typedef for the ioctl function pointer.

v2: Renamed KFD_COMMAND_(START|END) to AMDKFD_...

drm/amdkfd: reformat IOCTL definitions to drm-style

2015-01-06T17:44:36+00:00

This patch reformats the ioctl definitions in kfd_ioctl.h to be similar to the
drm ioctls definition style.

drm/amdkfd: Do copy_to/from_user in general kfd_ioctl()

2015-01-06T17:44:26+00:00

This patch moves the copy_to_user() and copy_from_user() calls from the
different ioctl functions in amdkfd to the general kfd_ioctl() function, as
this is a common code for all ioctls.

This was done according to example taken from drm_ioctl.c

drm/amdkfd: unmap VMID<-->PASID when relesing VMID (non-HWS)

2015-01-05T13:48:28+00:00

This patch fixes a bug where deallocate_vmid() didn't actually unmap the
VMID<-->PASID mapping (in the registers).
That can cause undefined behavior.

This bug only occurs in non-HWS mode.

drm/amdkfd: Load mqd to hqd in non-HWS mode

2015-01-04T19:46:44+00:00

This patch fixes a bug in DQM, where the MQD of a newly created compute queue
is not loaded to an HQD slot. As a result, the CP never reads packets from this
queue.

This bug happens only in non-HWS (hardware scheduling) mode. In HWS mode, the
CP is responsible of loading MQDs to HQDs slots.

amdkfd: actually allocate longs for the pasid bitmask

2014-12-28T16:44:37+00:00

Commit "amdkfd: use sizeof(long) granularity for the pasid bitmask" calculated
the number of longs it will need, but ended up allocating that number of
bytes rather than longs.

Fix that silly error and allocate the amount of data really required.

amdkfd: Fixing topology bug in building sysfs nodes

2014-12-02T14:41:08+00:00

Original code sent always 0 as the index number of the node. This patch fixes
this bug by sending a variable which is incremented per node.

amdkfd: Fix accounting of device queues

2014-12-07T20:27:24+00:00

This patch fixes a device QCM bug, where the number of queues were not
counted correctly for the operation of update queue. The count was incorrect
as there was no regard to the previous state of the queue.
