Collapse all Print all In new window Guaranteed allocation of huge pages (1G) using movablecore=N doesn't seem to work at all.

Hi! My system has 64G of ram and I want to create 32 1G huge pages to use in KVM virtualization, on demand, only when VM is running. So I booted the kernel with 'hugepagesz=1G hugepages=0 default_hugepagesz=1G movablecore=40G' However I still can't allocate the pages reliably. For instance this

[RFC v2] prctl: prctl(PR_SET_IDLE, PR_IDLE_MODE_KILLME), for stateless idle loops

It is common for services to be stateless around their main event loop. If a process sets PR_SET_IDLE to PR_IDLE_MODE_KILLME then it signals to the kernel that epoll_wait() and friends may not complete, and the kernel may send SIGKILL if resources get tight. See my systemd patch:
