Harish Kasiviswanathan 559e31d6ff Add API entrypoints for IPC functionality
Implement three new APIs for IPC buffer sharing:
	-hsaKmtShareMemory()
	-hsaKmtRegisterSharedHandle()
	-hsaKmtRegisterSharedHandleToNodes()

Add new ioclts necessary for the above APIs.

Lan Xiao 9cbbf30be7 libhsakmt: Add MarketingName and AMDName for all nodes - CPU & GPU
HSA thunk API is currently reporting engineering name to MarketingName
and returning NULL when querying for AMDName.

-Change current name reporting from MarketingName to AMDName.
-Use libpci to get MarketingName

Felix Kuehling 887b32fe86 Make hsaKmtAllocMemory more compliant with the Thunk spec
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.

Harish Kasiviswanathan ce83dc623f Don't limit number of supported GPUs
Stop using NUM_OF_SUPPORTED_GPUS. For now the definitions itself cannot
be removed as ioctl code is in upstream Kernel.

Harish Kasiviswanathan 5cc56a2647 Fix init process apertures
Kernel ioctl AMDKFD_IOC_GET_PROCESS_APERTURES returns process apertures
only for GPU nodes. The current implementation assumed that this list of
GPU nodes returned by the ioctl has one to one correpondence to sysfs
topology nodes. This fails when non-GPU nodes exist in topology as in
case of Intel + gfx802

Fix this by using gpu_id (./sys/.../kfd/topology/nodes/1/gpu_id) to map
information obtained from kernel ioctl call.

Felix Kuehling 6a5ca4bc5a Fix various dgpu memory management issues
Fix TONGA_PAGE_SIZE value and move it to libhsakmt.h for usiing it
consistently in all places that require the same alignment for the
same reason. Create a generic alignment helper macro to replace some
incorrect hand-coded size alignments.

Move virtual address and size alignments down into aperture management
functions. Alignment is a per-aperture property that is set during
fmm_init_process_apertures. Doing the alignment there ensures that
all allocations in the same aperture are aligned the same way. Finding
objects by size and address can take the alignment into account.

Also align the size of physical allocations to back aligned virtual
address allocations. CPU mappings do not need to be aligned.

Map anonymous pages over released memory mappings to allow the
backing pages to be released, while keeping the address space
reserved.

Add alignment parameter to free_exec_aligned_memory_gpu to match the
interface of allocate_exec_aligned_memory_cpu. It doesn't make sense
to allow an alignment parameter in one but assume a specific
alignment in the other.
