This commit introduces a new AvailableMemory API to the KfdDriver and
XdnaDriver classes.
- Implemented AvailableMemory in KfdDriver to return the available memory size
using hsaKmtAvailableMemory.
- Added a stub implementation of AvailableMemory in XdnaDriver that returns an error.
- Updated the GpuAgent class to use the new AvailableMemory API instead of
directly calling hsaKmtAvailableMemory.

Add AllocateScratchMemory interface to Driver base class and implement it
in both KFD and XDNA drivers. This change encapsulates the low-level
scratch memory allocation details within driver implementations, making
the code more maintainable and the interface cleaner.
The main changes include:
- Add AllocateScratchMemory virtual method to Driver interface
- Implement the interface in KfdDriver with existing allocation logic
- Add stub implementation in XdnaDriver
- Update GpuAgent to use the new interface instead of direct KMT calls

Move the wallclock frequency query from GpuAgent to driver layer to improve
code organization and support multiple driver types. This change:
1. Add GetWallclockFrequency API to KFD/XDNA drivers
2. Move libdrm GPU info query from GpuAgent to driver implementation
3. Update GpuAgent to use the new driver API

This commit introduces a new GetClockCounters API to the driver interface.
- Implemented GetClockCounters in KfdDriver to fetch clock counters
using hsaKmtGetClockCounters.
- Added a stub implementation of GetClockCounters in XdnaDriver that
returns HSA_STATUS_ERROR.
- Modified GpuAgent to use driver().GetClockCounters instead of
directly calling hsaKmtGetClockCounters.

This commit introduces a new GetDeviceHandle API to the driver
interface, allowing retrieval of the device handle for a
specific node.
- Implemented GetDeviceHandle in KfdDriver to fetch the AMD GPU
device handle using hsaKmtGetAMDGPUDeviceHandle.
- Added a stub implementation of GetDeviceHandle in XdnaDriver
that returns HSA_STATUS_ERROR.
- Modified GpuAgent::InitLibDrm to use driver().GetDeviceHandle
instead of directly calling hsaKmtGetAMDGPUDeviceHandle.

This change improves code maintainability and error handling by
centralizing DMABuf export functionality in the driver interface.
- Replace direct hsaKmtExportDMABufHandle calls with driver's ExportDMABuf method
- Improve error handling with more specific error status returns
- Add explicit invalid parameter checks and assertions
- Consolidate DMABuf export logic in IPC and VMemory paths
- Propagate detailed error status from driver layer

This commit introduces a new SetTrapHandler API to the driver interface
- Implemented SetTrapHandler in KfdDriver to set trap handlers using
hsaKmtSetTrapHandler.
- Added a stub implementation of SetTrapHandler in XdnaDriver that returns
HSA_STATUS_ERROR.
- Updated the driver interface in driver.h to include the new SetTrapHandler
method.
- Modified GpuAgent to use driver().SetTrapHandler instead of directly calling
hsaKmtSetTrapHandler.

Adding a general stage for agents to release their resources on
shutdown. This avoids a circular dependency during shutdown because
we have to delete allocated resources before deleting memory pools, but
we also have to delete memory pools before destroying agents.
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
Use the core Driver object in the CPU agent to make it OS/driver
agnostic.
Implement the GetMemoryProperties() and GetCacheProperties methods
for the KFD driver.
Generalize the driver discovery and move driver-specific
functionality to the concrete driver implementations.
Currently, this process is tightly coupled to the hsakmt
which is GPU and OS specific.

Return false if trying to free a NULL pointer (or invalid size)
internally in ROCr. This is to detect errors within ROCr when trying
to free NULL pointers. If a user of ROCr tries to free a NULL
pointer, this condition should be caught at the beginning of the
Runtime::FreeMemory(...) function and return HSA_STATUS_SUCCESS. This
matches the behavior of the free(...) or delete functions that
silently ignores calls when the passed a NULL pointer.

Adds support for AllocateMemoryOnly inside XDNA driver.
Move the IsLocalMemory() check inside the KFD driver
since the XDNA driver can, and needs to, create handles
on system memory buffer objects.
Changed handle variable name from thunk_handle to user_mode_driver_handle,
which is more representative if we support non-GPU drivers.

Adds support for initialzing the XDNA driver so that
a hardware context can be created for an AIE queue.
Right now this initializes the device heap in the driver,
gets the relevant tile parameters for the AIE agent,
and creates a hardware context that backs the AIE queue.

- Use HSA_ALLOCATE_QUEUE_DEV_MEM=1 to create AQL queue in device
memory.
- Before writing AQL packet header to the queue use an SFENCE to ensure
that there is no reodering of the writes over PCIE

Remove KFD-specific Allocate/Free calls from the AMD::MemoryRegion.
The KFD-driver-specific Allocate/Free calls are now implemented in
the KfdDriver. Future changes will migrate the remaining KFD-specific
calls out of AMD::MemoryRegion.
This allows the MemoryRegion to be used across AMD drivers like the
XDNA driver.

Adds the initial KFD driver interface and use it to open the
KFD from amd_topology.cpp.
This change is to show the direction of the Driver interface for
initially supporting the KFD and to get feedback on the approach.
For now we wrap relevant ROCt calls behind this generic driver
interface so that we can generalize core ROCr components like
MemoryRegion, Runtime, etc.
Now that ROCt is incorporated into ROCr, we can more fully integrate
ROCt into the Driver interface. Ideally, we get to a point where
the generic Driver interface can support KFD, XDNA, and potential
future drivers.
