The original version of hsa_amd_portable_export_dmabuf() did not
consider the conditions under which a dmabuf could be shared.
In the new version (hsa_amd_portable_export_dmabuf_v2()), the caller
can specify the flag HSA_AMD_DMABUF_MAPPING_TYPE_PCIE, which means they
want to share the dmabuf over PCIe. In that case, the new code will check
that if it is a PCIe GPU and it is not in a XGMI Hive then if
large-BAR is not supported, we will return an error.

On large BAR systems, for small-sized code-objects, we get performance
using direct memcpy due to latencies when doing the blit-copy.

Invalidate only the address range that covers the newly copied
code-object. This avoids invalidating I$ for old code objects and thus
might increase I$ hit rate.

[ROCm/ROCR-Runtime commit: 7ba77fb193]
Adds a bool to the GPU agent and a public member method to
check if the GPU supports large BAR. This is needed so we can
check if large BAR is supported when a user tries to allocate
an AQL queue in device memory on a given GPU agent.
Also adds an exception to the AQL queue if device-side AQL queues
are requested and the GPU owner of the AQL doesn't support large
BAR. Otherwise, ROCr will currently allow device-side queues
that can cause faults when the user tries to touch their ring
buffers and the user will not know why the faults are occuring.
This relies on the fact that the KFD does not exposed any links
from the CPU to the GPU if large BAR is not enabled (though
links from the GPU to the CPU may still be exposed by the KFD).
[ROCm/ROCR-Runtime commit: f2c482d923]
This builds on a prior change that allowed for allocating
a user-mode queue's packet buffer in device memory to also
allocate the queue struct in device memory. This provides
additional latency benefits particularly for cases where
dispatches are performed from the GPU itself. Flags are
added to support the various use cases.

- Add a new AMD extension API to return preferred SDMA engine mask.
This can use used in conjunction with copy_on_engine API to get
optimal bandwidth.

This patch will adds recommended sdma supports with
limited XGMI SDMA engine. It will use one PCIe SDMA
to do gpu <-> gpu copies which will help improve all

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.

Replaces WaitAny with WaitMultiple to more closely align with the
underlying driver API for waiting on multiple events.
WaitMultiple adds a single parameter, wait_on_all, to the WaitAny
interface providing a single function for waiting on multiple
events when we only need AND and OR semantics for the signal
checking logic.
