This variable is 0 by default. When set to 1, it means there is no frame
buffer, so all memory allocation is routed to system memory. This mode
is mainly used during emulation.
Use CoarseGrain for VRAM under ZFB mode

Because gfx700 has local memory but other APUs don't, we should reflect
that in the code. Meanwhile, fix a bug that on gfx902 svm aperture is not
added when calling hsaKmtGetNodeMemoryProperties().

__fmm_release actually fails to find the object if address is not
pagesize aligned. And the caller did not notice this as __fmm_release
has no err code return.
So to fix this, move the object lookup in caller, and use vm-object
instead. Also fmm_release will pass up the error code.

UCX test cases are reporting uninitialized values when CMA fails. The
application should ideally ignore SizeCopied when the function fails but
it doesn't. This is leading to wrong diagnosis.
v2: Fill in partial SizeCopied in case of failure

Libraries normally don't print messages. We use pr_err, pr_warn,
pr_info, and pr_debug to print messages to stderr when prints are
enabled for debugging.

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs
Also use this opportunity to spell manageable properly

Add two pointer attributes APIs:
hsaKmtQueryPointerInfo - allow the user to query the memory information
using a pointer. This pointer can point to any address inside the
range known to HSA.
hsaKmtSetMemoryUserData - allow the user to attach data to a pointer to
add memory tracking information. This pointer must match the start
address of a memory allocation or registration.
TODO: This patch implements support on dGPU. Needs to add APU.

Non-canonical GPUVM aperture doesn't exist on dGPUs. Remove comments

Use the object size when freeing address space, instead of the
parameter passed in by the caller. The parameter may be incorrect
due to app or runtime bugs, or when the buffers is an AQL ring
buffer with double mapping workaround.

Allocate SVM address space for the registered memory and use new
userptr support in KFD to create a system memory BO associated with
the given user pointer. Map this BO at the SVM address for CPU
access.
MapMemoryToGPU can be used with the registered user pointer and
will return the SVM address as alternate GPUVA.

Allocations from GPU nodes will return VRAM, not system memory.
Only non-paged allocation from GPU nodes is supported. System
memory can only be allocated from CPU nodes (usually node 0).
The HostAccess flag is no longer used to distinguish the memory
type. It only indicates, whether the memory is mapped for CPU
access.
Maintain compatibility with broken KfdTests by returning system
memory for paged-memory requested from GPU nodes.

Fix hsaKmtRegisterMemory to be a no-op for now and move the multi-GPU
implementation to hsaKmtRegisterMemoryToNodes. Make GPU memory mappings
of host memory visible to all GPUs by default. Device memory is still
visible to the allocating GPU only by default (but can be overridden
with hsaKmtRegisterMemoryToNodes for experimenting with P2P).

hsaKmtAllocMemory only allocates aligned address space and sets up

This is a hack to allow the Runtime to allocate system memory with
PreferredNode=0 on a dGPU system. We allocated it from Node 1
instead so that the node 1 GPU can map the memory. A proper fix
will be implemented together with multi-GPU support.
