linux-toradex.git/include/linux/hypervisor.h, branch v4.13-rc4 Linux kernel for Apalis and Colibri modules virt, sched: Add generic vCPU pinning support 2016-09-05T11:52:38+00:00 Juergen Gross jgross@suse.com 2016-08-29T06:48:43+00:00 47ae4b05d0fa2f2a998ebaf34d2dcbffca56a9db Add generic virtualization support for pinning the current vCPU to a specified physical CPU. As this operation isn't performance critical (a very limited set of operations like BIOS calls and SMIs is expected to need this) just add a hypervisor specific indirection.

Add generic virtualization support for pinning the current vCPU to a
specified physical CPU. As this operation isn't performance critical
(a very limited set of operations like BIOS calls and SMIs is expected
