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

([RISC-V] 2 Hours Ago Memory Hot Plugging/Unplugging)


The RISC-V kernel port with [1]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 [2]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.

Why, when no honest man will deny in private that every ultimate problem is
wrapped in the profoundest mystery, do honest men proclaim in pulpits
that unhesitating certainty is the duty of the most foolish and ignorant?
Is it not a spectacle to make the angels laugh? We are a company of
ignorant beings, feeling our way through mists and darkness, learning only
be incessantly repeated blunders, obtaining a glimmering of truth by
falling into every conceivable error, dimly discerning light enough for
our daily needs, but hopelessly differing whenever we attempt to describe
the ultimate origin or end of our paths; and yet, when one of us ventures
to declare that we don't know the map of the universe as well as the map
of our infinitesimal parish, he is hooted, reviled, and perhaps told that
he will be damned to all eternity for his faithlessness...
