This set of patches converts the way frames gets created from using PUSHes/POPs to using MOVes, thus allowing (in certain cases) to avoid saving/restoring part of the register set. While the place where the (small) win from this comes from varies between CPUs, the net effect is a 1 to 2% reduction on a combined interruption entry and exit when the full state save can be avoided. 1: use MOV

hi,everybody There is a function do_IRQ() in file xen/arch/x86/irq.c, but where does do_IRQ() be called please? Thanks! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This

1: correct LDT checks 2: add address validity check to guest_map_l1e() 3: use {rd,wr}{fs,gs}base when available 4: check for canonical address before doing page walks Signed-off-by: Jan Beulich <jbeulich@suse.com>

The following patches shave some rough edges off the tools build system to allow cross compiling for at least arm32 and arm64 based on the Debian/Ubuntu multiarch infrastructure. They also add the necessary fixes to build for arm64 (which I have only tried cross, not native). I have posted some instructions on how to compile with these patches on the wiki:

Hello, This series has been split into two patches, one for arm and one for x86. I figured that this was easier than doing it as a single combined patch, especially as the changes are functionally independent. x86 has been boot tested, but arm has not even been compile tested as I lack a suitable cross compiler. However, the changes are just text replacement, so I dont expect any issues. The

The first patch really isn''t as much of a follow-up than what triggered the security issues to be noticed in the first place. 1: x86: preserve FPU selectors for 32-bit guest code 2: x86: fix XCR0 handling 3: x86/xsave: adjust state management 4: x86/fxsave: bring in line with recent xsave adjustments The first two I would see as candidates for 4.3 (as well as subsequent backporting,

Hi all, these are the remaining unapplied patches of the ARM HDLCD patch series. Changes in v7: - rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0; - turn more printk and panic into early_printk and early_panic. Changes in v6: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795; - remove useless initializations to NULL in lfb_init; - more compact checks in lfb_init. Changes in v5: - move

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.

First off, Apologies for the massive patch series... This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8 (AArch64) model. The kernel is the same one as I am currently using with the 32 bit hypervisor I haven''t yet tried starting a guest or anything super advanced like that ;-). Also there is not real support for 64-bit domains at all, although in one or two places I
