Hello, I am trying to compile RHEL-6 kernel srpm on Fedora 14 and run into the following problem. From what I read -Werror flag causes warnings to be treated as errors - but I don't see that flag on in the following. Any ideas? gcc -Wp,-MD,arch/x86/kernel/acpi/realmode/.wakemain.o.d -nostdinc -isystem /usr/lib/gcc/i686-redhat-linux/4.5.1/include -nostdinc -isystem

Tom, in his laconic way, doesn't want to explain to us why is this even needed... :) /me reads the code /me reads the GHCB spec aha, it gets it from the HV. And it

Hello, I read in the announce of Xen 3.2.0 released that it has "preliminary support for a wider range of bootloaders in fully virtualised (HVM) guests, using full emulation of x86 ''real mode''" . I''d like to know what is the level of the emulation of x86 ''real mode''? I ask that because I tried to install OpenSuse 10.3 (I used the iso file

I was trying to install Ubuntu 7.10 on an HVM domain, when when the install kept hanging at a particular point. xm dmesg shows the following : (XEN) realmode.c:132:d28 Failed to emulate insn. (XEN) realmode.c:174:d28 Real-mode emulation failed @ 0000:00007f34: 0f 2c 06 08 6b 04 (XEN) domain_crash called from realmode.c:175 (XEN) Domain 28 (vcpu#0) crashed on cpu#0: (XEN) ----[ Xen-3.4-unstable

Hi, Keir, This patch is to fix the problem of Linux guest installation failure and Windows 2000 boot failure.       In the early code, we use vmx_vmexit_handler() -> vmx_io_instruction() function to emulate I/O instructions. But now, we use vmx_vmexit_handler() -> handle_mmio -> hvm_emulate_one() -> x86_emulate() to emulate I/O instructions. Also nowadays, the realmode

All, in the light of erratum #573 I''m wondering if we need to tweak or conditionally suppress fsincos emulation. The question is whether there is any possibility for getting the emulator to hit this instruction on AMD (as no real mode emulation ought to be taking place there), i.e. whether there are places where emulation gets continued eagerly in anticipation of the need for emulation

From: Joerg Roedel <jroedel at suse.de> Hi, here is the fourth version of the SEV-ES Guest Support patches. I addressed the review comments sent to me for the previous version and rebased the code v5.8-rc5. The biggest change in this version is the IST handling code for the #VC handler. I adapted the entry code for the #VC handler to the big pile of entry code changes merged into

Hi, here is the first public post of the patch-set to enable Linux to run under SEV-ES enabled hypervisors. The code is mostly feature-complete, but there are still a couple of bugs to fix. Nevertheless, given the size of the patch-set, I think it is about time to ask for initial feedback of the changes that come with it. To better understand the code here is a quick explanation of SEV-ES first.

From: Joerg Roedel <jroedel at suse.de> Hi, here is a rebased version of the latest SEV-ES patches. They are now based on latest tip/master instead of upstream Linux and include the necessary changes. Changes to v4 are in particular: - Moved early IDT setup code to idt.c, because the idt_descr and the idt_table are now static - This required to make stack protector work early (or
