similar to: how to set cpuid ?

This is a bug fixing. So it needs go into 4.1. x86: add volatile prefix for cpuid asm clauses cpuid results are possible to be changed now. For example, changing CR4.OSXSAVE bit or setting MSR XCR_XFEATURE_ENABLED_MASK may change XSAVE related cpuid leave return values. The volatile prefix is required to avoid the second cpuid calls following some possible changing operations being optimized in

Did something had chaqnged with spice code or settings. I just compiled latest git of 4.4 unstable and I get is a black screen all I see is the green boot image from server 2012 but I dont get blue windows logo and window does not resize it stays black. I reverted back to older git revision of 4.4 and everything is working fine with. _______________________________________________ Xen-users

I want to be able to test live migration... I have an intel box and an amd box, so live migration between them won''t ''just work''. From what I''ve read though, I should be able to use cpuid to turn off all the cpu features which might be different between them. Is this do-able? I''m willing to accept any resulting loss of performance etc. James

I have few instance of server 2008 running on xen. i want to configure them to redirect sound. I guess I need xen to emulate sound card, Somone had stated that they are working on patch that will support intel hda emulation was this ever acomplished? Xen supports ac97 is there 64 bit driver for ac97 on server 2008 ? _______________________________________________ Xen-users mailing list

Hi, xl is currently ignoring the cpuid= variable in the config file. As I don''t like the current interface xm exposes (basically because it is complicated, unintuitive and very error prone), I implemented a new scheme for specifying CPUID flags policy, combining QEMU''s and Xen''s approach: cpuid = "<base>,<feature_name>=[01xks]*,... The patch includes a

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or

Hi all, I recently upgraded my Xen 3.2.1 to 3.3.1 on Centos 5.2. Everything seems to have gone pretty smoothly except I have a few issues.

Attached SVM patch fixes a virtualization of the CPUID NX bit, and cleans up other CPUID bits. Applies cleanly to xen-unstable.hg 10177. Applies to xen-3.0-testing 9696. Please apply to xen-unstable.hg. Please apply to xen-3.0-testing.hg. Tested on top of the KY patches for XCHG (HVM) and SMP SVM support. Keir, Can those 2 patches KY posted last week, also be applied to 3.0.2?

- use __clear_bit() rather than clear_bit() - use switch statements instead of long series of if-s - eliminate pointless casts (Applies cleanly only on top of the previously sent SVM/EFER patch.)

I just wonder why xen 4.4 unstable presents it self as xen 4.3 unstable ? boot message states 4.3 unstable and efi is 4.3 unstable? I wonder what is the reason behind it ? _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Hi, all Some Latest Intel CPU models (CPUID.1.EAX >= 0x00010674) support cupid mask features. Cpuid feature mask is used to limit the feature flags reported by CPUID.1.EDX:ECX. This small patch adds CPUID feature mask support in XEN by adding boot options in Grub entry as below example: kernel /boot/xen.gz com1=115200,8n1 console=com1 cpuid_mask_ecx = 0xFFFF7FFF cpuid_mask_edx = 0xFFFFFFFC

Hi, this patch passes the orginal cpuid bits for X86_FEATURE_DTES64 (64-bit DS Area) and X86_FEATURE_DSCPL (CPL Qualified Debug Store) to the guest when the BTS feature is switched on.

Keir, In July we implemented cpuid faulting feature, and checked in xen-unstable tree as c/s 23653/23654/23655. Today we patched them to xen-4.1.0, test result shows it''s OK to work with xen-4.1.0. So how about backporting this feature to xen-4.1.0? Thanks, Jinsong _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com
