While the ternary is nice to read, strlen in general is an expensive
call, so call it once and check if the value is greater than our maximum
allowable string length and adjust accordingly

libpci was only used to find a marketing string for a device.
This patch looks for a pci.ids on disk and parses it to extract the
same string, using 'Device xxxx' as the fallback on file i/o error
or missing data from the text file. Tested by checking every vendor/
device pair against the values returned from libpci.

NumCpQueues and NumSdmaQueuesPerEngine should be got by kfd driver not hardcode.
So add two data fields in HsaNodeProperties then thunk is able to get it from sysfs
that exposed by kfd.
v2: change NumCpQueues/NumSdmaQueuesPerEngine to one byte.
v3: merge two commits as one to avoid ABI update two times.

On NUMA system, allocate queue ctx save restore area on the closest NUMA
node to the GPU which the queue is going to run. This will improve
performance on NUMA system generally by reducing schedule latency and
fix the multi-node rccl-tests unstable performance issue.
If the closest NUMA node has no memory available, set flags NoNUMABind=1
to bypass mbind, to use default NUMA memory policy to allocate system
memory.

Force all the GPUs to a certain type, use the below command:

meaning major.minor.step dgpu asic_name asic_id
This will faciliate the cooperation across the teams for bringing up
ASICs which reuse existing device IDs.

snprintf throws a warning from -Wformat-truncation where the string
could be truncated. We address this by referencing the maximum size that
can be returned from a file according to MAXNAMLEN . This should safely
guard us from truncating the path value.

Replace cpuid call with sysfs data to get CPU cache information. With this
change, x86 check is also removed since sysfs applies to other platforms.
CPU cache information can be retrieved from
/sys/devices/system/node/nodeX/cpuY/cache where Y is processor number
represented in /proc/cpuinfo at "processor" entry.

/proc/cpuinfo are opened, read, and closed multiple times. Once for vendor
name and multiple times for model name -- each node opens once. For example
in a 2 CPUs + 4 GPUs system, it'll be opened 7 times. This patch reads it
one time and stores it in a cpuinfo buffer. This cpuinfo buffer is freed
when the snapshot is done.
Also replace returns with gotos inside the snapshot to avoid possible
memory leak.
