The main change from the patches I sent out earlier this week is support for guests that use the PIC. A callback for PIC irq ack handling is also introduced. Currently, there's no mechanism to register/unregister callers to the irq ack callbacks, but they can be added when there's more than one user for the functionality. Please review.

Wei, Quick question: Am I reading the code correctly, that even with per-device interrupt remap tables, that GSIs are accounted to the intremap table of the corresponding IOAPIC, presumably because the IOMMU sees interrupts generated as GSIs as coming from the IOAPIC? In that case, then we need all devices sharing the same IOAPIC must not have any vector collisions. Is that correct? -George

This patchset introduces PCI passthrough support for KVM. This has been tested with an Ethernet device. The device is seen in the guest and interrupts are generated. However, no data transfer can take place unless pvdma or reserved-ram is used. The patches for pvdma will be available shortly. Sharing of interrupt line for the PCI device on the host side will cause slowness (and / or some

Hello, when I try to start xend I receive this error: root@xenized:~# xend start ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory) Traceback (most recent call last): File "/usr/sbin/xend", line 36, in <module> from xen.xend.server import SrvDaemon File

During boot of dom0, I get the following. Box is remote, so I''m now waiting for proxy power button pusher ;-) tg3 init fails doing dma_alloc_coherent (I assume this is from tg3_init_one -> tg3_test_dma -> pci_alloc_consistent -> dma_alloc_coherent). Looks like an issue with the amount of memory in dom0. Is this known? thanks, -chris root (hd0,0) Filesystem type is ext2fs,

For IOAPIC interrupt remapping, it only needs to remap ioapci RTE, should not remap other IOAPIC registers, which are IOAPIC ID, VERSION and Arbitration ID. This patch adds the check for this and only remap ioapci RTE.

I have the same motherboard. The chipset has 2 IOAPICs: one in the NB (00:00.1), and another in the SB (00:14.0). As currently configured by the BIOS, the NB IOAPIC is _entirely_ disabled, with only the SB IOAPIC enabled and configured. From 48693.pdf, it would seem that the NB is improperly configured, as 6.4.1 recommends that "The IOAPIC shou...

(I accidently (cross) posted this also in the xen-bugs mailing list. This wasn''t my intention. Sorry for that) Hi, I have two kernels vmlinuz-2.6.32-5-amd64 vmlinuz-2.6.32-5-xen-amd64 As you can see, distributions are the same, the latter differs by loading xen stuff. When booting the xen kernel (vmlinuz-2.6.32-5-xen-amd64) I noticed a problem which does not occur in the non

Hi Konrad, I just tried to boot a 3.8.0-rc0 kernel (last commit: 7313264b899bbf3988841296265a6e0e8a7b6521) as dom0 on my machine with current xen-unstable.

Hi, I am running a Xeon with hyperthreading support. Until last week's HTT modifications, according to ps(1) and top(1) both logicals CPUs were in use. (Processes in CPU0 and CPU1 state; "C" column showing "0" or "1".) This has changed with a recent -STABLE kernel which includes last week's changes to HTT (removing "options HTT"). I am only seeing

All. I am running Xen on an ES7000 system with 4 procs and 4 GB memory. I am running Suse Sles-9 (32-bit) on the machine. I have compiled Xen (the tip on the unstable tree : 6552) with PAE enabled (XEN_TARGET_X86_PAE=y). The system boots fine. I started xend and when I tried to bring up a virtual machine, the system gave me the following error on the command line. On the serial port, I saw an

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs. However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use. However, I'd like (and think that it's possible, but don't remember how) to

Hi, We did an upgrade of one of our machines from an Aug 25 CVS and ever since then one of the machines likes to reboot about once a day. The machine is the following: IBM x340 2x1GHZ Processors 1GB RAM 3x36GB Drives (RAID 5) Mylex ExtreRAID 352 In the panic it mentions httpd, but I don't *think* it's apache (1.3.27) that's causing the problem, or am I wrong? I also believe it is

After some dialog with Terry Lambert on -hackers, I've been advised to post this here. I have a 4.7-RELEASE-p10 box that is suffering regular kernel panics. The machine is a Dell 2650 running primarily as a file/print server to a number of computer labs of about 400 machines (although it also functions as a rembo image server and squid proxy). It mainly stores applications, which
