No code change, just add comments about things being official instead of assumptions. The Gen5 specs is pretty-much finalized, things won't change anymore. Signed-off-by: Brice Goglin <[email protected]>
Check that Linux can add NUMA nodes to x86 CPU information. And check that Linux can annotate x86 AMD topoext NUMA nodes. Signed-off-by: Brice Goglin <[email protected]>
If the workspace clone ever ran on another branch (e.g. in my zbgoglin jobs), git branch returns multiple lines, which causes the 2nd branch name to be ran as a command-line after the only expected line "job-0-tarball.sh <firstbranch>" Use git rev-parse --abbrev-ref HEAD instead.

This tells the code not to ever merge that group with structurally-identical parent or children. This is useful for Groups implementing new "types" that cannot be backported to stable releases. New types won't be merged by default, but Groups would. Requested by Intel for Die objects. This doesn't break the ABI because the attribute structure has always been calloc'ed, which means this attribute was "0", which matches the default "merge group" behavior.

Update CPUID.1f x86 test case not to merge Die groups anymore. Hence there's no need to ignore Caches anymore. Signed-off-by: Brice Goglin <[email protected]>

I managed to convince Intel that adding another foo_siblings between core_siblings and thread_siblings would break userspace and situation could be even worse if they ever add another intermediate level in the future. So they are finally renaming to filenames whose semantics doesn't depend on intermediate levels: core_cpus and package_cpus. Signed-off-by: Brice Goglin <[email protected]>
Linux 5.3 will have new "die_cpus" and "die_id" sysfs files for upcoming architectures with multiple dies per packages. When the die cpuset is different from the package, add a "Die" group. Don't add it when there's a single Die per package because most CPUs don't want to show a useless additional Die level. We don't want to set the Die level to keep_structure because it would get automerged in L3 caches on CLX, and lstopo displays everything by default anyway. Set the "dont_merge" group flag if HWLOC_DONT_MERGE_DIE_GROUPS is set in the environment, just like in the x86 backend. Signed-off-by: Brice Goglin <[email protected]>
Old kernels exposed two packages on E5v3 in Cluster-on-Die mode because the package core_siblings was wrong. We detected that case when two packages had the same physical_package_id. This was fixed in Linux 3.18, backported in RHEL7. Other important distros use a more recent kernel now. Signed-off-by: Brice Goglin <[email protected]>

They are renamed to PREFIX_hwloc_FOO instead of PREFIX_HWLOC_FOO We could fix it but it doesn't matter much (people aren't supposed to use those renamed names anyway) and it could break existing hacks (if anybody actually depends on such renamed name).

…ectory fsroot and cpuid are implemented in tools using environment variables (those debug cases are not in the API since v2). Those backends forced by environment variable override the normal topology thissystem flag that may be set with set_flags() in the API and with --flags or --thissystem in cli tools. One must use the HWLOC_THISSYSTEM envvar to force the this system flag. Implement this automatically in the tools (common helpers). Signed-off-by: Brice Goglin <[email protected]>

Yes.
I am busy at the moment.
I'll let you know as soon as I am done!

This branch is an addition to exisitng hwloc_distrib() method to distribute cpusets of the topology.
It adds a new way to iterate over topology objects of a single level with a hierarchical policy.
Utility hwloc-distrib has been modified to reflect the new capabilities.
This branch purpose is to bring thread binding policies to hwloc toolset by using it with hwloc-thread-bind branch.
