This patch adds VirtIO support to the libhsakmt library, enabling communication
with AMD GPUs via VirtIO.
Details
- CMakeLists.txt: Added a new CMakeLists.txt file for the VirtIO component
of libhsakmt.
- hsakmt_virtio.c/h: Implemented the core VirtIO functionality, including
VirtIO GPU device initialization, command execution, and memory management.
- virtio_gpu.c/h: Contains the implementation of the VirtIO GPU device,
including ioctl handling, shared memory management, and command execution.
- hsakmt_virtio_events.c: Implements event handling for VirtIO, such as event
creation, destruction, setting, resetting, and querying event states.
- hsakmt_virtio_memory.c: Manages memory operations for VirtIO, including memory
allocation, freeing, mapping, and unmapping.
- hsakmt_virtio_queues.c: Implements queue management for VirtIO, including
queue creation, destruction, and updating.
- hsakmt_virtio_topology.c: Handles system and node properties for VirtIO.
- hsakmt_virtio_vm.c: Manages VM-related operations for VirtIO, such as
reserving and dereserving VA space.
- include/linux/virtgpu_drm.h: Contains DRM definitions for VirtIO GPU.
Key Features
- VirtIO GPU Initialization: The library can now initialize a VirtIO GPU device
and communicate with it.
- Command Execution: Supports executing commands on the VirtIO GPU device.
- Memory Management: Provides functions for allocating, freeing, mapping, and
unmapping memory for VirtIO operations.
- Event Handling: Implements a comprehensive event system for VirtIO.
- Queue Management: Allows for creating, destroying, and updating queues
on the VirtIO GPU device.
- System and Node Properties: Retrieves and manages system and node
properties for VirtIO.

- Refactored scratch memory handling by introducing fmm_is_scratch_aperture to
replace repeated for-loops.
- Simplified code paths in hsakmt_fmm_release, hsakmt_fmm_map_to_gpu, and
hsakmt_fmm_unmap_from_gpu by using the new helper.

This patch changes the type of several loop index variables from int to
uint32_t in fmm.c. The affected functions are:
- __fmm_release
- _fmm_map_to_gpu
- _fmm_unmap_from_gpu
To fix compile warning:

If unmap from GPU return failed, for example, unmap user queue buffer
while queue is active, we should not free obj->mapped_node_id_array,
otherwise, the following unmap user queue buffer after queue is

Random driver deadlock on svm_range_evict_svm_bo_worker() is obeserved on
NPS2/DPX mode. It's seen with xnack off and happens more often on the
partition with less VRAM because of TMR.

This builds on a prior change that allowed for allocating
a user-mode queue's packet buffer in device memory to also
allocate the queue struct in device memory. This provides
additional latency benefits particularly for cases where
dispatches are performed from the GPU itself. Flags are
added to support the various use cases.
The max queues per process is 1024 in KFD,
KFDQMTest.OverSubscribeCpQueues fails with multi-gpu mode
on more than 15 gpus, because 65x16=1040 exceeds 1024, so
changing MAX_CP_QUEUES to adapt it will fix the issue.

The debugger override will set the initial request mask to the
previously set request mask so use a different mask to assert
enablement.
Trap on wave start and end also run back to back, so fix the
previous override mask check as well.
In addition, unlike instruction traps, trap on wave start and end
will not require a rewind of the program counter on wave exit.
The over arching goal it so provide an API that pre-silicon models can latch into for software bring up.# Please enter the commit message for your changes. Lines starting

BUILD_SHARED_LIBS is a global flag so we don't need to set a default
option for it in both libhsakmt and hsa-runtime, only the top level
CMakeLists file. Also updated README to reflect that libhsakmt is
always built statically and gets linked to libhsa-runtime.
