Since the sub-buffer(virtual memory that is mapped to device memory) is associated with device memory, it should utilize the device context instead of the host context. The original implementation caused hipMemcpyPeer to not take the P2P path, as the memory object was treated as host memory.
Convention is to always link against .so.* at runtime.
Having it link against .so will break on systems that package
the .so files in their dev/devel package.
This issue was found when building ROCm 6.4 for Fedora.

* SWDEV-520352 - Remove HostThread and legacy monitor
Remove HostThread, semaphore and legacy monitor.
Make original logics of thread and command queue stricker.
Add more comments to make logics clearer.
Some other minor improvement.
Also part of SWDEV-458943.
- When a command may possibly have two packets(like device heap
initializer), and if there is no signal on the main kernel packet the
tracking was broken as it marked HW event of the command as the first
packet signal.
- Make sure if no completion signal is attached to the second packet
then clear the HW event for the command.
* SWDEV-518831 - fix streams' sync issue in mthreads
1. Fix sync issue of null stream and non-null streams in
multithreads.
2. Remove assert(GetSubmissionBatch() == nullptr) as it
is invalid in multithreads.
3. Update getActiveQueues() to deal with the state of
being terminated.
The compiler currently serializes the workgroup_processor_mode COMGR metadata boolean field as "0"/"1" instead of "false"/"true". Consider "1" a truthy value during parsing.
* SWDEV-517078 - Maintain the trap handler ABI version in CLR
The trap handler ABI version is communicated to the debugger using
the r_version field in the r_debug structure. This structure is
an external dependency, which makes it complicated to keep the trap
handler source (in CRL) and the ABI version number (external dependency)
in sync.
This patch proposes to patch the trap handler ABI version number in
_amdgpu_r_debug before communicating it to the debugger.
We can't directly include sc's executable.hpp file in CRL as it relies
on conflicting definition of ELF related types, so instead we need to
rely on a-priori knowledge on the r_debug structure. Fortunately, this
structure is part of a stable ABI, so its layout is guaranteed to be
kept stable.
Update the 2nd level trap handler to follow updates from the
ROCr-runtime. The trap handlers are stripped from parts dedicated to
architectures unsupported by CLR.
Bump the r_debug.r_version to track the ABI changes in the trap handler.
Needs further debugging but for now can test the change
Need to verify if this fixes all the below issues-
SWDEV-512754, SWDEV-511675, SWDEV-511055, SWDEV-504085, SWDEV-499503
Also verify original issues

- For D2H cases avoid passing dependent signals to SDMA, the signals
take a while to resolve on SDMA engine
