Hi everyone, I would like to ask what the current status of FLR, or better of FLR emulation is in latest Xen and if we can expect better support in the future. I''m asking because with xl (latest build and traditional qemu, not upstream), I always had problems with rebooting domUs which have vga cards passed through to them, because appearently they don''t get reinitialized and

Hi Andi, This series of patches updates paravirt_ops in various ways. Some of the changes are plain cleanups and improvements, and some add some interfaces necessary for Xen. The brief overview: add-MAINTAINERS.patch - obvious remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed paravirt-nop.patch - mark nop operations consistently paravirt-pte-accessors.patch - operations to pack/unpack

Hi Andi, Here's a repost of the paravirt_ops update series I posted the other day. Since then, I found a few potential bugs with patching clobbering, cleaned up and documented paravirt.h and the patching machinery. Overview: add-MAINTAINERS.patch obvious remove-CONFIG_DEBUG_PARAVIRT.patch No longer meaningful or needed. paravirt-nop.patch Clean up nop paravirt_ops functions, mainly to

Paravirt ops is currently only capable of either replacing a lot of Linux internal code or none at all. The are users that don't need all of the possibilities pv-ops delivers though. On KVM for example we're perfectly fine not using the PV MMU, thus not touching any MMU code. That way we don't have to improve pv-ops to become fast, we just don't compile the MMU parts in! This

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -
