From: Rusty Russell <rusty@rustcorp.com.au> lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's 5000 lines and self-contained. Performance is ok, but not great (-30% on kernel compile). But given its hackability, I expect this to improve, along with the

The sense of the IF bit is backwards in the host interrupt handling. This means we always save "IF=1" on the stack when injecting an interrupt. It turns out this is almost always correct (unless the guest is taking a page fault in an interrupt due to an unpopulated vmalloc mapping), so went unnoticed.

[ I think this is a straight repost this patch, which addresses all the previous comments. I'd like to submit this for .24 as the basis for a unified paravirt_ops. Any objections? ] This patch refactors the paravirt_ops structure into groups of functionally related ops: pv_info - random info, rather than function entrypoints pv_init_ops - functions used at boot time (some for module_init

Here's a first attempt at splitting up paravirt_ops into more specific chunks. Its pretty clunky and chunky; mostly just a lot of replacement. The grouping of ops is very first cut; I'm open to suggestions about what groups should exist and what ops they each should contain. The only slightly subtle part is that I've kept the structures wrapped in a paravirt_ops structure,

This version over last version: (1) Gets rid of the no_paravirt.h header and leaves native ops in place (with some reshuffling to keep then under one #ifdef). (2) Fixes the "X crashes with CONFIG_PARAVIRT=y" bug. (3) Puts __ex_table entry in paravirt iret. Another followup patch implements binary patching... Rusty. === Create a paravirt.h header for all the critical operations which

The patch_default label is only used from within case PARAVIRT_PATCH(pv_lock_ops.queued_spin_unlock) and case PARAVIRT_PATCH(pv_lock_ops.vcpu_is_preempted) i.e. when #if defined(CONFIG_PARAVIRT_SPINLOCKS) is true. Therefore no code jumps to this label in case CONFIG_PARAVIRT_SPINLOCKS is not defined and label should be removed in that case. Moving #endif directive just after that label fixes the

In a future patch, the NATIVE_* instruction string macros will be used in GCC extended inline asm, which requires registers to have two '%' instead of one in the asm template string. Convert the DEF_NATIVE macro to the GCC extended asm syntax so the NATIVE_* macros can be shared more broadly. Signed-off-by: Josh Poimboeuf <jpoimboe at redhat.com> ---
