Title:
[HMEM] Allow persistent memory to be used like normal RAM
Status in intel:
Fix Committed
Status in linux package in Ubuntu:
New
Bug description:
Description
Persistent memory is cool. But, currently, you have to rewrite
your applications to use it. Wouldn't it be cool if you could
just have it show up in your system like normal RAM and get to
it like a slow blob of memory? Well... have I got the patch
series for you!
This series adds a new "driver" to which pmem devices can be
attached. Once attached, the memory "owned" by the device is
hot-added to the kernel and managed like any other memory. On
systems with an HMAT (a new ACPI table), each socket (roughly)
will have a separate NUMA node for its persistent memory so
this newly-added memory can be selected by its unique NUMA
node.
Target Kernel: 5.1
Target Release: 19.04
