drm/amdkfd: Module option to disable CRAT table

2017-12-09T04:09:03+00:00

Some systems have broken CRAT tables. Add a module option to ignore
a CRAT table.

drm/amdkfd: Add topology support for dGPUs

2017-12-09T04:08:59+00:00

Generate and parse VCRAT tables for dGPUs in kfd_topology_add_device.

Some information that isn't available in the CRAT table is patched
into the topology after parsing.

HSA_CAP_DOORBELL_TYPE_1_0 is dependent on the ASIC feature
CP_HQD_PQ_CONTROL.SLOT_BASED_WPTR, which was not introduced in VI
until Carrizo. Report HSA_CAP_DOORBELL_TYPE_PRE_1_0 on Tonga ASICs.

v2: Added #include  to kfd_crat.c to make it compile

drm/amdkfd: Add topology support for CPUs

2017-12-09T04:08:58+00:00

Currently, the KFD topology information is generated by parsing the CRAT
(ACPI) table. However, at present CRAT table is available only for AMD
APUs. To support CPUs on systems without a CRAT table, the KFD driver will
create a Virtual CRAT (VCRAT) table and then the existing code will parse
that table to generate topology.

drm/amdkfd: Support enumerating non-GPU devices

2017-12-09T04:08:53+00:00

Modify kfd_topology_enum_kfd_devices(..) function to support non-GPU
nodes. The function returned NULL when it encountered non-GPU (say CPU)
nodes. This caused kfd_ioctl_create_event and kfd_init_apertures to fail
for Intel + Tonga.

kfd_topology_enum_kfd_devices will now parse all the nodes and return
valid kfd_dev for nodes with GPU.

drm/amdkfd: Use ref count to prevent kfd_process destruction

2017-11-27T23:29:52+00:00

Use a reference counter instead of a lock to prevent process
destruction while functions running out of process context are using
the kfd_process structure. In many cases these functions don't need
the structure to be locked. In the few cases that really do need the
process lock, take it explicitly.

This helps simplify lock dependencies between the process lock and
other locks, particularly amdgpu and mm_struct locks. This will be
important when amdgpu calls back to amdkfd for memory evictions.

drm/amdkfd: Make kfd_process reference counted

2017-11-27T23:29:51+00:00

This will be used to elliminate the use of the process lock for
preventing concurrent process destruction. This will simplify lock
dependencies between KFD and KGD.

This also simplifies the process destruction in a few ways:
* Don't allocate work struct dynamically
* Remove unnecessary hack that increments mm reference counter
* Remove unnecessary process locking during destruction

drm/amdkfd: Add debugfs support to KFD

2017-11-27T23:29:49+00:00

This commit adds several debugfs entries for kfd:

kfd/hqds: dumps all HQDs on all GPUs for KFD-controlled compute and
    SDMA RLC queues

kfd/mqds: dumps all MQDs of all KFD processes on all GPUs

kfd/rls: dumps HWS runlists on all GPUs

drm/amdkfd: map multiple processes to HW scheduler

2017-11-27T23:29:45+00:00

Allow HWS to to execute multiple processes on the hardware
concurrently. The number of concurrent processes is limited by
the number of VMIDs allocated to the HWS.

A module parameter can be used for limiting this further or turn
it off altogether (mainly for debugging purposes).

drm/amdkfd: Add CWSR support

2017-11-14T21:41:19+00:00

This hardware feature allows the GPU to preempt shader execution in
the middle of a compute wave, save the state and restore it later
to resume execution.

Memory for saving the state is allocated per queue in user mode and
the address and size passed to the create_queue ioctl. The size
depends on the number of waves that can be in flight simultaneously
on a given ASIC.
