Hey all,
We're looking to develop UEFI Secure Boot support for grub-loaded Xen and
ultimately for XCP-ng (I'm on the XCP-ng team at Vates).
In addition to carrying the chain-of-trust through the entire boot sequence
into dom0, we would also like to build something akin to Linux's Lockdown for

In Credit2, the CPUs are assigned to runqueues according to the host
topology. For instance, if we want per-socket runqueues (which is the
default), the CPUs that are in the same socket will end up in the same
runqueue.
This is generally good for scalability, at least until the number of

When doing an assisted flush on HAP the purpose of the

In Credit2 CPUs (can) share runqueues, depending on the topology. For

On platform with a huge number of CPUs per socket, that could be a

Ring1 is full of architectural corner cases, such as counting as supervisor
from a paging point of view. This accounts for a substantial performanc

There is no need to save/restore FS/GS/XCR0 state. It will be handled
suitably on the context switch away from the idle.
The CR4 restoration in restore_rest_processor_state() was actually fighting
later code in enter_state() which tried to keep CR4.MCE clear until everything
was set up. Delete t

The value returned from CPUID is the maximum number for virtual
processors supported by Hyper-V. It could be larger than the maximum

Stash the configured number into a variable and use it in calculations.

The XS_INTRODUCE command has two parameters: the mfn (or better: gfn)
of the domain's xenstore ring page and the event channel of the
domain for communicating with Xenstore.
The gfn is not really needed. It is stored in the per-domain struct
