We need the IB test for GPU resets as well and
the scheduler should be stoped then.

This patch adds the events module (kfd_events.c) and the interrupt
handle module for Kaveri (cik_event_interrupt.c).

The patch updates the interrupt_is_wanted(), so that it now calls the
interrupt isr function specific for the device that received the
interrupt. That function(implemented in cik_event_interrupt.c)
returns whether this interrupt is of interest to us or not.

The patch also updates the interrupt_wq(), so that it now calls the
device's specific wq function, which checks the interrupt source
and tries to signal relevant events.

v2:

Increase limit of signal events to 4096 per process
Remove bitfields from struct cik_ih_ring_entry
Rename radeon_kfd_event_mmap to kfd_event_mmap
Add debug prints to allocate_free_slot and allocate_signal_page
Make allocate_event_notification_slot return a correct value
Add warning prints to create_signal_event
Remove error print from IOCTL path
Reformatted debug prints in kfd_event_mmap
Map correct size (as received from mmap) in kfd_event_mmap

v3:

Reduce limit of signal events back to 256 per process
Fix allocation of kernel memory for signal events

This patch adds support for SDMA mqd operations:
- init_mqd_sdma
- uninit_mqd_sdma
- load_mqd_sdma
- update_mqd_sdma
- destroy_mqd_sdma
- is_occupied_sdma

It also adds SDMA queue information to some private structures of amdkfd.

v3: Use the new names of some of the defines.

The MQDs for CI and VI are different. Therefore, the MQD manager module need to
be H/W specific.

This patch splits the current MQD manager into three files:

- kfd_mqd_manager.c, which contains common functions and initializes the
  specific mqd manager module according to the H/W

- kfd_mqd_manager_cik.c, which contains Kaveri specific functions. This is
  basically the old kfd_mqd_manager.c

- kfd_mqd_manager_vi.c, which will contain VI specific functions. Currently it
  is not implemented except for returning NULL on initialization.

Because amdkfd will need to work both with radeon and amdgpu, don't include
header files that are in radeon's folder.

Instead, use the common amd include folder and move amdkfd specific defines to
amdkfd header files.

The mqd_manager module handles MQD data structures.
MQD stands for Memory Queue Descriptor, which is used by the H/W to
keep the usermode queue state in memory.

v3:

Removed new typedefs
Removed pragma pack 4
Remove cik_mqds.h file
Changed lower_32/upper_32 calls to use linux macros
Used new gart allocation functions
Added documentation

v4:

Added missing initialization of the addr field in init_mqd()

Setting the hqd persistent.preload_req bit ON so that when queues switches
on/off, their context will kept and read from the mqd when the cp reassign
them, and thus the dispatched workload context kept consistent without any
interrupts.

v5:

Move amdkfd from drm/radeon/ to drm/amd/
Change format of mqd structure to match latest KV firmware
Add support for AQL queues creation to enable working with open-source HSA
runtime.
