Cover letter [PATCHv8 00/10] Heterogenous memory node attributes
== Changes since v7 ==
Fixed an early return that prevented reporting HMAT when there are no direct attached initiators.
Fixed introducing a variable that was unused until several patches later.
Miscellaneous typos, editorial clarifications, and whitespace fixups.
Merged to most current linux-next.
Added received review, test, and ack by's.
I've published a git tree available on this branch:
https://git.kernel.org/pub/scm/linux/kernel/git/kbusch/linux.git/log/?h=hmat-v8
== Background ==
Platforms may provide multiple types of cpu attached system memory. The memory ranges for each type may have different characteristics that applications may wish to know about when considering what node they want their memory allocated from.
It had previously been difficult to describe these setups as memory rangers were generally lumped into the NUMA node of the CPUs. New platform attributes have been created and in use today that describe the more complex memory hierarchies that can be created.
This series' objective is to provide the attributes from such systems that are useful for applications to know about, and readily usable with existing tools and libraries. Those applications may query performance attributes relative to a particular CPU they're running on in order to make more informed choices for where they want to allocate hot and cold data. This works with mbind() or the numactl library.
