Hi all, I'm a new user to LLVM. Not really sure if this is the correct place to post, since there isn't really any other forums around. Anyway, the issue I'm encountering is that, I was trying out the first tutorial (http://llvm.org/docs/tutorial/JITTutorial1.html). I attempted to do this in another folder that was copied from llvm/projects/sample. I created a new folder called

Hi all, I''ve been trying to understand the pci_setup function in hvmloader.c in Xen unstable. I''m kinda lost at Line 328. base = (resource->base + bar_sz - 1) & ~(bar_sz - 1) I''d appreciate if someone could explain to me why base is calculated this way. Specifically, I don''t understand the bitwise AND with the one''s complements of

I have a chipset which supports VT-d (Intel X58) and, according to my motherboard manufacturers, VT-d is enabled in the BIOS and listed as "Intel VT." The problem is that xm dmesg shows "I/O virtualisation disabled" and I get this error message when I try to create a domU with a pci device assigned: ''Error: failed to assign device: maybe the platform doesn''t

We have tested the latest xen on VT platform with Intel 915/E8500 chipset. Three platforms (32/PAE/32E) test all are based on SMP, It means that we boot up SMP guest OS in VMX.

Hi all, I find that SPEC cpu2k benchmark will always fail (9 of 10 times) for ia32 smp hvm guest with 4 vcpus. I used 4 users parameter to run cpu2k and assign 1G memory for the guest, but it will always fail when running 164.zip case and report warnings as the attachments. However, cpu2k could be run successfully in native linux and xenU guest with the same configuration. Anyone has ideas about

Ever since xen-unstable cset 14308 ("pci back: Fix registration of of filters on subsections of config space") I''ve been getting an MCA on the *2nd* boot of a driver domain using an e1000 NIC. Cset 14308 allowed the proper setup of the PM control registers, so the NIC is put in the D3 power state when the driver domain shuts down. Unfortunately, pci_set_power_state()

Hmm.. good question. I don''t know, it''s always done for me here. One option would be to just download OVM from edelivery.oracle.com,

Enable cpufreq support in Xen for AMD Operton processors by: 1) Allowing the PowerNow! driver in dom0 to write to the PowerNow! MSRs. 2) Adding the cpufreq notifier chain to time-xen.c in dom0. On a frequency change, a platform hypercall is performed to scale the frequency multiplier in the hypervisor. 3) Adding a platform hypercall to the hypervisor the scale the frequency multiplier and reset

What is the point of specifying "current" as the address to monitor? The memory location of interest really is irq_stat[cpu].__softirq_pending, and if that was used it would then also be possible to actually avoid sending IPIs when monitor/mwait are in use, as is being done on Linux.
