Some infrastructures below,
Implement SdmaTimePacket which records the global GPU timestamp.
Introduce class AsyncMPSQ and AsyncMPMQ.
AsyncMPSQ is aka async multiple packet single queue. It takes a set of
packet when create and submits them to a GPU to run. While AsyncMPMQ is
aka async multiple packet multiple queue. It manages a set of AsyncMPSQ,
and use a forloop to do operations of AsyncMPSQ.
Implement sdma_multicopy helper functions.

This fixes ambiguity when looking up GPU addresses with
hsaKmtQueryPointerInfo.
hsa_amd_agents_allow_access uses hsaKmtQueryPointerInfo, and
depends on finding the correct object from a GPU address. Finding
the wrong userptr object based on its CPU address leads to
incorrect GPU mappings and results in VM faults.

all subtly different, partially incomplete, or broken ways of doing
this in various functions:
* map
* unmap
* register
* deregister
* free
* get_mem_info
* set_mem_user_data

got a bit more complex when the userptr address can match the GPU

Currently, all HSA nodes are exposed to user. So the existing
implementation assumes a one to one mapping between user
NodeId and sysfs nodeId.
GPU Resource Management will provide control over the exposed
HSA nodes. This means not all HSA nodes will be exposed to the user.
Decouple it.
The mapping from user NodeId to sysfs NodeId will be local
to topology.c and topology helper functions. For others NodeId
should be sequential from 0 to Number of Nodes exposed to user.

v2: map node id within the topology_* functions

[ROCm/ROCR-Runtime commit: 62f7dc2a48]
So far we have assumed that userptrs are always memory outside
reserved SVM apertures that are mapped into the SVM aperture for
GPU access.
With an unreserved SVM aperture that covers the entire virtual
address range, this distinction will no longer be true. Userptrs
will generally be inside the unreserved SVM aperture. Take that
into consideration when registering, mapping and unmapping virtual
addresses.
We now need a retry logic when looking up buffers from addresses.
If it is not found by its GPU address, try it as a userptr.
We also need to consider the new possibility that a userptr is
registered at the same address for CPU and GPU access. So a buffer
found by its GPU address may also turn out to be a userptr. In
that case use a stricter lookup using the userptr and size (if
the size is known), to identify the correct one of multiple
overlapping objects.

coherency. Replace it with different conditions based on mem flags
