RISC-V Memory Hot Plugging To Be Introduced With Linux 6.11

The RISC-V kernel port with Linux 6.11 is introducing the ability to handle memory hot plugging/unplugging.

Similar to Linux on x86_64 and other CPU architectures, RISC-V with the upcoming Linux 6.11 cycle is set to land support for memory hot (un)plugging. Linux's memory hot (un)plug support allows increasing/decreasing the physical memory size at run-time. Yes, this can be useful if physically (un)plugging memory DIMMs to your running RISC-V server, but more commonly this memory hot plugging is useful in the context of virtual machines (VMs) and increasing/decreasing the exposed memory at run-time to the VM.

For those interested in the RISC-V memory hot plugging implementation for the Linux kernel can find all the details via this merge to RISC-V's "for-next" code of new material set to be upstreamed in mid-July with the Linux 6.11 merge window.
