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.

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.

This commit was ported from old repo.
Original author: Ranjith Ramakrishnan <Ranjith.Ramakrishnan@amd.com>
For static builds use drm and drm_amdgpu static libraries for linking.
Created a separate cmake target file and static library for static use case
The config file will include the respective target file based on
BUILD_SHARED_LIBS.
Default target file will be the one where drm and libdrm_amdgpu shaed libraries
are linked.
Applications using statically linked cmake targets of hsakmt should install the
required static libraries before building.

[ROCm/ROCR-Runtime commit: 9e8477e1c9]
Create a new top-level CMakeLists.txt file to control building thunk
and ROCr. kfdtest and rocrtest are built separately.
Most of the cmake code that existed for thunk, ROCr, rocrtst and kfdtest
still reside in their respective CMakeLists.txt files, except the
CPack packaging directives which have been moved to the top-level
CMakeLists.txt.
