Rob,
I gather this was with the complete -ck patchset? It would be interesting to
see if just SD
performed as well. If it does, CFS needs more work. if not there are other
things in -ck
that really do improve performance and should be looked into.

Hi List,
I'm using NPTL multi-threaded library and kernel 2.4.
When a new thread is created using the pthread_create call the returned
thread handle is pthread_t.
I want to get the kernel thread id for this pthread - means similar to
what gettid returns when it's called by the thread itself.

Some operand fetches are less than the machine word size and can result in
stale bits if used together with operands of different sizes.

This patch just renames the current (misnamed) _arch namings to _x86 to
ensure better readability when a real arch layer takes place.

From: Laurent Vivier <[EMAIL PROTECTED]>
The mutex->splinlock convertion alllows us to make some code simplifications.
As we can keep the lock longer, we don't have to release it and then
have to check if the environment has not been modified before re-taking it. We
can remove kvm->busy and
This will help moving the main loop to subarch independent code.

Before preempt notifiers, kvm needed to allocate memory with GFP_NOWAIT so
as not to have to enable preemption and take a heavyweight exit. On oom, we'd
fall back to a GFP_KERNEL allocation.
With preemption notifiers, we can do a GFP_KERNEL allocation, and perform
the heavyweight exit only if

This patch changes the PIC interrupts delivery. Now it is only delivered
to vcpu0 when either condition is met (on vcpu0):
1. local APIC is hardware disabled
2. LVT0 is unmasked and configured to delivery mode ExtInt

APIC timer IRQ is set every time when a certain period
expires at host time, but the guest may be descheduled
at that time and thus the irq be overwritten by later fire.

This patch enables TPR shadow of VMX on CR8 access. 64bit Windows using
CR8 access TPR frequently. The TPR shadow can improve the performance of
access TPR by not causing vmexit.

Because lightweight exits (exits which don't involve userspace) are many
times faster than heavyweight exits, it makes sense to emulate high usage
devices in the kernel. The local APIC is one such device, especially for
Windows and for SMP, so we add an APIC

This reduces overhead by accessing cachelines from the wrong node, as well
as simplifying locking.

vmx_load_host_state() bundles fs, gs, ldt, and tss reloading into
one in the hope that it is infrequent. With smp guests, fs reloading is
frequent due to fs being used by threads.
Unbundle the reloads so reduce expensive gs reloads.

This patch adds a new vcpu-based IOCTL to save and restore the local
apic registers for a single vcpu. The kernel only copies the apic page as
a whole, extraction of registers is left to userspace side. On restore, the
