The interrupt stack table (IST) mechanism is the only thing preventing
kvm from deferring saving and reloading of some significant state. It
is also somewhat complicated.
Remove it by switching the special exceptions to use the normal irqstack.
Changes from v1:
- rebase on tip/master
- as a step, consolidate stack switching into a single macro
Jeremy, Xen is also affected; please review.
Avi Kivity (4):
x86: drop the use of the tss interrupt stack table (IST)
x86: Consolidate irq stack switching to a single macro
x86: Make interrupt stack switching atomic
x86: Move NMI back to interrupt stack

Peter Anvin; +Cc: jeremy, linux-kernel, kvm The IST is the only thing that requires a valid TSS while running in kernel mode. Dropping its use unlocks an optimization opportunity for kvm: if we don't need a valid TSS while in kernel mode we can defer the use of the VMLOAD/VMSAVE instructions until the next context switch, reducing the executions of these costly instructions by a nice factor. Kernel reliability should also be improved since interrupt paths are simplified.

They have the following commit IDs, and they are also in tip/master: 921e521: x86: move NMI back to interrupt stack 36ef6c9: x86: make interrupt stack switching atomic dd64891: x86: consolidate irq stack switching to a single macro 955a368: x86: drop the use of the tss interrupt stack table (IST) I also started testing them in tip-qa. I added the standard Impact-lines that we do in the x86 tree. Note that this patch: dd64891: x86: consolidate irq stack switching to a single macro isnt just consolidating IRQ entry assembly code, it is also changing the paranoidentry macros to do IRQ stack entries - and hence switches all but the NMI critical exception entries sequences over to the IRQ stack. Your later patch: 921e521: x86: move NMI back to interrupt stack covers the NMI entry code too. Please double-check that we indeed now have all the critical exceptions on the IRQ stack (they are all rare so testing alone wont show this), and please also double-check that we dont have more exceptions and entry callpaths on the IRQ stack than what we wanted. For example on a preemptible kernel (or in any codepath that calls schedule()) it is fatal to be on the IRQ stack, so this has to be very accurately coded.

I've pushed out the bad kernel to the tip/tmp.master.bad branch: fe3aac9: Merge branch 'x86/irq' (no crashlog available - all i know that the box crashed and rebooted, when booted with the bzImage built out of the attached config.)
