Detect invalid/unsupported configurations in iommu_alloc() - offsets read from hardware must not lead to exceeding a single page (since only that much gets mapped). This covers the apparently not uncommon case of the address pointed to by a DMAR reading as all ones (Linux for example also checks for this). Further correct error handling of that function: Without storing the allocated "struct

Hi Yonghyeon and All, >From time to time I use a notebook and boot FreeBSD from USB stick. FreeBSD 9.2-i386 works OK. So I tried to use FreeBSD 10.0-i386 BETA2 and the network adapter works for some 10-15 seconds and then stops with diagnostic message "msk0:watchdog timeout". I've found similar case at freebsd-current@ with no workaround. Yes, there is an interrupt storm as well.

Hello guys, I have a problem when using my MSI R9 380 4G graphic card as GPU passthrough with KVM. At the first linux boot (Fedora 23) I am able to successfully start virtual machine and it works! However if i will shut down virtual machine and start it again - the screen will stay blank! So far I have been able to find on the internet that some graphic cards just can not reinitialize itself

Hi, We're having some trouble with detection of a couple of Sil3124 SATA controller cards on newer motherboard and processor combos. Specifically, we're running a Supermicro X9SCM-F motherboard (latest BIOS) and Intel E3-1220v2 CPU. What we're seeing: - Syba Sil3124 PCIe cards are only being detected when installed in PCIe Slot 4 -- The motherboard documentation shows that this

I'm trying to pass-through my VGA card to a guest session. I found: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM - which is very frustrating because there's no date on the documentation. I suspect it's old. It does clearly say that you must have VT-d support for pci pass-through. It then goes on to say "Some work towards allowing this ["software

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's

Hi, I''m not able to activate VT-d on my PC due to a buggy BIOS. Xen fails to parse ACPI DMAR table. There is a problem with RMRR address range. My configuration is : - Debian Weezy - Xen version 4.1.2 (Debian 4.1.2-2) - Sabertooth X58 with last bios (1304) - i7 - 960 I have the following message : (XEN) [VT-D]dmar.c:704: Host address width 39 (XEN) [VT-D]dmar.c:719: found

Hi list, I have a problem with a new laptop (reproducable on other machines too) and the xen hypervisor. When the hypervisor gets booted with VESA mode 800x600 I see some messages and then the screen contents is switched into a pattern of vertical colored lines and never comes back. In text mode all works well, but later the pattern appears when the X servers starts. I disabled VTd in the bios

Hi, I have been trying out a nice new tws controller and decided to enable debugging in the kernel and run some stress tests. With a regular GENERIC kernel, it boots up fine. But with debugging, it panics on boot. Anyone know whats up ? Is this something that should be sent directly to LSI ? pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0

Jan, I was given a machine to diagnose a boot problem on xen 4.3, that used to work on 4.2, and have bisected to the following changeset: commit d0d4635d034f202bb401a6efa3ba61530f3854ab Author: Jan Beulich <jbeulich@suse.com> Date: Thu Nov 22 10:47:58 2012 +0100 implement vmap() ... and use it as basis for a proper ioremap() on x86.
