Subject: [PATCHv7 00/10] Heterogenous memory node attributes
Date: Wed, 27 Feb 2019 15:50:28 -0700 [thread overview]
Message-ID: <20190227225038.20438-1-keith.busch@intel.com> (raw)
== Changes since v6 ==
Updated to linux-next, which has a change to the HMAT structures to
account for ACPI revision 6.3.
Changed memory-side cache "associativity" attribute to "indexing"
Regarding the Kconfig, I am having the implementation specific as a user
selectable option, and the generic interface, HMEM_REPORTING, is not a
user prompt. I just wanted to clarify the point that there's only one.
== 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.
