similar to: PAE issue (32-on-64 work)

I''m not seeing the problem that Fan Zhao is reporting, instead I get this one. Not sure if ti''s the same one or a different problem... This happens with my simple-guest [i.e. not using hvmloader, as I described before]. This worked fine yesterday.

Attempting to boot xVM dom0 for the first time on a Toshiba Tecra M2 running 75a. Getting a panic immediately after selecting xVM from the grub menu: panic[cpu0]/thread=f502c020: Processor does not support PAE This is a 2000 MHz Pentium-M, which I thought was PAE-capable.

Hi all, I''m currently running on Ubuntu Dapper and xen 3.0 testing. I noticed my sound card didnt work. I looked in dmesg and found this: Apr 9 17:49:29 phoenix kernel: [ 27.490852] architecture does not support 28bit PCI busmaster DMA Grepping the kernel I came up with this, from sound/pci/ice1712/ice1712.c: /* check, if we can restrict PCI DMA transfers to 28 bits */

Fix PAE shadow on a machine with RAM above 4G on x86_64 xen. Currently, on a machine with RAM above 4G, we can not run 32bit VMX guest on x86_64 xen, the root cause is that the PAE page table PDPT must below 4G, this patch fixes this issue. Also did some cleanup. Signed-off-by: Xin Li <xin.b.li@intel.com> Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>

In p2m.c (line 197 and line 550), the code assumes the number of L3 P2M table entries is 8 (under PAE mode). According to Intel and AMD specs, it is 4. Could someone explain this discrepancy? Is it a bug? -Wei _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Folks -- One more time with the PAE request, this time I''ve brought up the Linux kernel w/ a very recent version of Xen. (Just yesterday I pulled and updated my hg tree.) I still can''t set breakpoints within the guest domain: # gdb vmlinux GNU gdb 6.4-debian <...> (gdb) target remote roti.lab.netapp.com:9999 Remote debugging using roti.lab.netapp.com:9999 [New

The patch enables x86_32 PAE unmodified guests on 64-bit Xen when the hvm feature is present. We tested only Linux at this point, and we''ll improve the functionality as we test other guests. The SVM needs the equivalent changes to the vmc.c to get this functionality working, but this patch does not break the build. Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>

In a recent conversation one of my coworkers raised a concern about memory limitations when running 32-bit guests on top of the 64-bit hypervisor. At this point the discussion is academic; I don''t know when/if we''ll ever be able to get system resources to test it, to see if the concerns that he expressed are real. So I decided to post this in hope of getting comments from the

Is it intentional that - under SVM, 32-bit guests can freely set EFER.LME - under VMX, 32-bit guests can''t access EFER at all? Thanks, Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

We currently ship a PAE 32-bit domU that we can trivially make bimodal, except that if we set it to "bimodal", then older Xens will default to thinking the domU is not PAE: 353 dsi->pae_kernel = PAEKERN_no; 354 if ( dsi->__elfnote_section ) 355 { 356 p = xen_elfnote_string(dsi, XEN_ELFNOTE_PAE_MODE); 357 if ( p != NULL && strncmp(p,

Hello, I''m new to Xen and especially to the hypervisor code. I''m working off a 3.0.4.1 base and have the following questions regarding the memory management code for an x86, 32-bit platform (capable of supporting PAE). I''m doing some research into providing grant table hypercall support from a Windows 2003 HVM. I have made all the necessary changes to allow the

Btw., another question that made me wonder already when doing the original patch: why is it that x86-64 properly uses locking for mm_pin_all(), yet i386 doesn''t need to?

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: Zhang Xiantao <xiantao.zhang@intel.com> With virtual EPT support, L1 hyerpvisor can use EPT hardware for L2 guest''s memory virtualization. In this way, L2 guest''s performance can be improved sharply. According to our testing, some benchmarks can show > 5x performance gain.

This is a patch repairing a regression in code previously functional in 4.1.x. It appears that, during some refactoring work, calls to hvm_memory_event_cr3 and hvm_memory_event_cr4 were lost. These functions were originally called in mov_to_cr() of vmx.c, but the commit http://xenbits.xen.org/hg/xen-unstable.hg/rev/1276926e3795 abstracted the original code into generic functions up a level in
