On some asics, like tonga, the memory alignment size is as big as 0x8000.
fmm_allocate* alloc vm area with size passed in which is not aligned mostly.
But __fmm_release free vm area with vm_object_t->size which is aligned.
That might cause aperture_release_area fail to free the vm area as the
size might be bigger than zone itself or it just free another vm area
nearby unexpected.
This patch somehow will alloc more space than it needed on tonga.
gfx900+ is not affected.

Previously we used the first dgpu mem, but after careful examination, we
found it only needs to be a GPU, so we modify the code to reflect that as
well.

Implement sDMA copy packet broadcast.
Each time sDMA will copy its local vram to sysbuf and next GPU's vram.
That will verify where the p2p link is broken.
Currently we just test push of p2p.

The information can be obtained directly from node id. Also improve the

Unset ret_addr when unmapping the address space reservation. Otherwise
it may try to unmap it again later.
Remember the actual map_size and use it instead of len outside the
reservation loops.

Both the include and libpath were incorrect after recent build
system changes. Use the proper GNUInstallDirs definitions in
libhsakmt.pc.in to write the proper locations.
This is needed for end users building KFDTest, which depends on
correct pkg-config information.

This test has been intermittently failing for various reasons and
was already disabled on all chips except Ellesmere. It stresses
memory management in unusual ways by having lots of memory allocated
but +# not mapped, which is not relevant to compute applications over
ROCr.

This is to coordinate kfd kernel vram limit change, and adding
GFX vram allocation with submission of command nop is to
trigger eviction.

$1 is passed in during install/upgrade/uninstall. If this is an
uninstall, remove the ldconf file, otherwise leave it. In yum-based
systems, the uninstall from the old package is executed after the
post-install of the newer package, which will undo the ldconf work from
the newer package.

A README.txt file is added to help the opensource community to use kfdtest
effectively.
After building, run_kfdtest.sh in the building output folder can be used
to run the test.

Conserves VMIDs when multiple processes are in use and memory operations
are not GPU specific. For instance HIP API hipHostMalloc does not accept
a target GPU so when used with one process per GPU (ie GPU == MPI rank) we can
quickly exceed the available VMID slots if every process consumes a VMID on
every GPU.
