* libhsakmt/virtio: Add alloc memory align api
Signed-off-by: Honglei Huang <honghuan@amd.com>
* libhsakmt/virtio: Rename CLGL BO to AMDGPU BO
Rename VHSA_BO_CLGL to VHSA_BO_AMDGPU to support generic AMDGPU buffer objects, not just CL/GL interop.
* libhsakmt/virtio: Add atomic helpers and node lookup
Add vhsakmt_atomic_inc/dec macros and vhsakmt_get_node_by_id helper function.
* libhsakmt/virtio: Add AMDGPU device initialization support
Add vamdgpu_device_initialize and vamdgpu_device_deinitialize functions.
* libhsakmt/virtio: Add AMDGPU device handle and DRM command support
Add vamdgpu_device_get_fd, vdrmCommandWriteRead and update vhsaKmtGetAMDGPUDeviceHandle.
* libhsakmt/virtio: Add AMDGPU BO free and CPU map support
Add vamdgpu_bo_free and vamdgpu_bo_cpu_map functions.
* libhsakmt/virtio: Add AMDGPU BO import and export support
Add vamdgpu_bo_import, vamdgpu_bo_export and vhsakmt_bo_from_resid functions.
* libhsakmt/virtio: Add AMDGPU BO VA operation support
Add vamdgpu_bo_va_op function.
* libhsakmt/virtio: Add dma buf export support
Add vhsaKmtExportDMABufHandle API in virtio driver to support export
feature.
* libhsakmt/virtio: Fix potential deadlock in userptr deregistration
Refactor vhsakmt_deregister_userptr_non_svm to avoid calling
vhsakmt_destroy_userptr while holding the bo_handles_mutex lock.
Previously, destroying userptrs directly while iterating the tree
could cause deadlock issues due to nested locking.
- Move interval tree removal from vhsakmt_destroy_userptr to caller
- Collect BOs to free in a temporary array during tree traversal
- Destroy BOs after releasing the mutex to avoid lock contention
- Use dynamic array with realloc to handle arbitrary number of BOs

* rocr: driver/virtio: Implement DMA-BUF import/export and memory mapping APIs
Implement the missing DMA-BUF handling and memory mapping functions
in the virtio KFD driver to enable cross-process memory sharing:
- ExportDMABuf: Export HSA memory as DMA-BUF file descriptor
- ImportDMABuf: Import DMA-BUF fd as shareable buffer object
- Map: Map imported buffer into virtual address space with permissions
- Unmap: Unmap buffer from virtual address space
- ReleaseShareableHandle: Free imported buffer object
Also add drm_perm() helper to convert HSA access permissions to
AMDGPU VM page flags (READABLE/WRITEABLE).
These APIs enable IPC memory sharing between HSA processes through
DMA-BUF mechanism in virtualized environments.

* libhsakmt/virtio: Add register memory APIs
Add two new memory registration functions to the virtio HSA KMT library:
1. vhsaKmtRegisterMemory: A simplified wrapper for vhsaKmtRegisterMemoryWithFlags
that uses default CoarseGrain memory flags.
2. vhsaKmtRegisterMemoryToNodes: A stub implementation for registering memory
to specific nodes. Returns HSAKMT_STATUS_NOT_IMPLEMENTED as it's currently
not used in ROCR.
Changes:
- Added function declarations in hsakmt_virtio.h
- Implemented functions in hsakmt_virtio_memory.c
- Exported symbols in libhsakmt_virtio.ver

* libhsakmt/virtio: Add graphics handle registration and mapping APIs
- Add vhsaKmtRegisterGraphicsHandleToNodesExt() with flags support
- Add vhsaKmtMapGraphicHandle() and vhsaKmtUnmapGraphicHandle() stubs
- Refactor existing registration API to use extended version

* libhsakmt/virtio: Add virtio support for queue APIs
Implement vhsaKmtUpdateQueue, vhsaKmtSetQueueCUMask,
vhsaKmtAllocQueueGWS and vhsaKmtGetQueueInfo functions
with virtio protocol extensions and symbol exports.

* libhsakmt/virtio: Add new virtio API support for model, SMI, and XNACK mode
Add three new API functions to the virtio backend:
- vhsaKmtModelEnabled: Check if pre-silicon model is enabled (returns false for virtio)
- vhsaKmtOpenSMI: Open SMI interface for a node (not yet supported in virtio)
- vhsaKmtSetXNACKMode: Set XNACK mode via virtio control command

* libhsakmt/virtio: Add shared memory support for virtio backend
Implement shared memory APIs for the virtio backend to enable
memory sharing between processes:
- Add vhsaKmtShareMemory() to share memory regions and create
shared memory handles
- Add vhsaKmtRegisterSharedHandle() to register shared memory
handles in the current process
- Add vhsaKmtRegisterSharedHandleToNodes() for node-specific
shared memory registration

* libhsakmt/virtio: Add memory management APIs for virtio
Add the following new memory management APIs to virtio implementation:
- vhsaKmtSetMemoryUserData: Set user data for memory pointer
- vhsaKmtSetMemoryPolicy: Configure memory policy for nodes
- vhsaKmtSVMGetAttr: Get SVM (Shared Virtual Memory) attributes
- vhsaKmtSVMSetAttr: Set SVM attributes
- vhsaKmtReplaceAsanHeaderPage: ASAN header page replacement (stub)
- vhsaKmtReturnAsanHeaderPage: ASAN header page return (stub)

* libhsakmt/virtio: Add SPM APIs
Add three new SPM-related APIs to the virtio interface:
- vhsaKmtSPMAcquire: Acquire SPM resources on a preferred node
- vhsaKmtSPMRelease: Release SPM resources on a preferred node
- vhsaKmtSPMSetDestBuffer: Set destination buffer for SPM data with
optional userptr support and data loss detection
These APIs extend the virtio command protocol with new query types:
- VHSAKMT_CCMD_QUERY_SPM_ACQUIRE
- VHSAKMT_CCMD_QUERY_SPM_RELEASE
- VHSAKMT_CCMD_QUERY_SPM_SET_DST_BUFFER
The implementation includes proper buffer management for both
direct BO access and userptr fallback for smaller buffers.

* libhsakmt/virtio: Add virtio stub for hsaKmtAisReadWriteFile API
Add vhsaKmtAisReadWriteFile stub implementation for the virtio backend

- Add stub implementation in hsakmt_virtio_memory.c
- Export the symbol in libhsakmt_virtio.ver

* libhsakmt/virtio: Add vamdgpu_bo_query_info and vamdgpu_bo_set_metadata APIs
Implement two new virtio wrapper functions for AMDGPU buffer object operations:
1. vamdgpu_bo_query_info: Query buffer object information including
allocation parameters, memory usage, and metadata.
2. vamdgpu_bo_set_metadata: Set metadata for a buffer object, allowing
applications to attach custom data to GPU memory allocations.

* libhsakmt/virtio: Add ProcessVMRead/Write stub implementations for virtio
Add vhsaKmtProcessVMRead and vhsaKmtProcessVMWrite stub functions
to the virtio interface. These APIs return HSAKMT_STATUS_NOT_IMPLEMENTED
since they are not supported in the baremetal implementation, matching
the behavior of the deprecated hsaKmtProcessVMRead/Write APIs.
