[PATCH V2] x86/AMD-Vi: Add additional check for invalid special->handle
From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>
This patch add an additional logic to check for the often case when the
special->handle is not initialized due to firmware bugs.
but the special->usedid is correct. If users overide this using the
command line option ivrs_ioapic, then it should use the value instead.

This patch is supposed to follow the patches:
[Xen-devel] [PATCH RFC 2/2] AMD IOMMU: allow command line overrides for broken IVRS tables
Changes in V2:
- Fix logic to match the special->used_id with the value provided by users.

AMD IOMMU disabled - No Perdev Intremap
Hi!
From other people posting to this list, I know that there has been a
bug related to the issue described in Xen Security Advisory 36 that
disables iommu for some AMD users like me.
However, even when passing "iommu=no-amd-iommu-perdev-intremap" it
still disables i/o virtualisatoin. Related Xen dmesg output:
(XEN) IVHD Error: Invalid IO-APIC 0
(XEN) AMD-Vi: Error initialization

How to boot linux kernel from Syslinux 6 with efi
...ease prebuilt
binaries. I copy efi64/efi/syslinux.efi to /EFI/boot/booyx64.efi. Then
I run the following from the root of the Syslinux-6.01 (with the
usb flashdrive mounted at /mnt):
# start: syslinux.cfg
LABEL Debian
linux /vmlinuz.efi
initrd /initrd.img
append root=/dev/sda3 ro \
ivrs_ioapic[7]=00:14.0 ivrs_ioapic[8]=00:00.1
# end: syslinux.cfg
Same kernel command line currently works with grub-2.00 from efi booting
from EFI System Partition on first hard drive. And
also from gummiboot-32 from same usb flashdrive.
Hardware I am using is:

[xen-unstable] Commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, makes dom0 boot process stall several times.
Hi Jan,
After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times.
Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times.
(It also stalls on shutdown BTW)
I have
