Hello, I'm getting the "LLVM ERROR: ran out of registers during register allocation" error message for an out of tree target I'm developing. This is happening for the following piece of C code: struct ss { int a; int b; int c; }; void loop(struct ss *x, struct ss **y, int z) { int i; for (i=0; i<z; ++i) { x->c += y[i]->b; } } The problem relies in

Hi all, I am trying to install OpenSUSE 11.1 as a para-virtualized DomU on an opensolaris2009.06 guest using the xvm packages provided via IPS. I followed the instructions available here: http://www.opensolaris.org/os/community/xen/docs/virtinstall/ but I get the following error when trying to install from a NFS share where I mounted the iso (as far as I understand the only way to get a Linux

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6. I've got a working blkio cgroup hierarchy which I'm attaching guests to using the following XML guest configs: VM1 (foreground): <cputune> <shares>2048</shares> </cputune> <blkiotune> <weight>1000</weight> </blkiotune>

1) Rename vp_request_vectors to vp_request_msix_vectors, and take non-MSI-X case out to caller. 2) Comment weird pci_enable_msix API 3) Rename vp_find_vq to setup_vq. 4) Fix spaces to tabs 5) Make nvectors calc internal to vp_try_to_find_vqs() 6) Rename vector to msix_vector for more clarity.

This refactors find_vqs, making it more readable and robust, and fixing two regressions from 2.6.30: - double free_irq causing BUG_ON on device removal - probe failure when vq can't be assigned to msi-x vector (reported on old host kernels) An older version of this patch was tested by Amit Shah.

Here's the patch series I ended up with. I haven't coded up the QEMU side yet, so no idea if the new driver works. Questions: (1) Do we win from separating ISR, NOTIFY and COMMON? (2) I used a "u8 bar"; should I use a bir and pack it instead? BIR seems a little obscure (noone else in the kernel source seems to refer to it). Cheers, Rusty.
