[PATCH] AMD IOMMU: add missing checks
For one we shouldn''t accept IVHD tables specifying IO-APIC IDs beyond
the limit we support (MAX_IO_APICS, currently 128).
And then we shouldn''t memset() a pointer allocation of which failed.

[PATCH] x86: allow Dom0 read-only access to IO-APICs
There are BIOSes that want to map the IO-APIC MMIO region from some
ACPI method(s), and there is at least one BIOS flavor that wants to
use this mapping to clear an RTE''s mask bit. While we can''t allow the
latter, we can permit reads and simply drop write attempts, leveraging
the already existing infrastructure introduced for dealing with AMD
IOMMUs'' representation as

refactoring io_apic.c
OK, I need to do something like this to io_apic.c - split the hardware
specific parts out under mach-default, so we can override them for other
subarchitectures. It's not finished, needs header file and makefile
work. Would you be willing to take this if I do it? I'm not going to
bother if you're not, such refactorings are a pig to maintain out of
tree.

[PATCH] x86: change IO-APIC ack method default for single IO-APIC systems
Ever since 3.0.2 we''ve been carrying this patch in our products. Since
there was no indication that there would be anything wrong with the
''new'' IO-APIC ack method added back then, we finally decided to drop
this patch recently from SLE11, to find that the subsequent release
candidate failed to work on at least on system without using

[PATCH 0/3] IOMMU errata treatment adjustments
1: IOMMU: properly check whether interrupt remapping is enabled
2: AMD IOMMU: only disable when certain IVRS consistency checks fail
3: VT-d: deal with 5500/5520/X58 errata
Patch 1 and 2 are version 2 of a previously submitted, then
withdrawn patch following up after XSA-36. Patch 3 is version 3 of
a patch previously sent by Malcolm and Andrew.

[PATCH] IRQ: Group IRQ_MOVE_CLEANUP_VECTOR with other hypervisor IPIs
Also, rename to MOVE_CLEANUP_VECTOR to be in line with the other IPI
names.
This requires bumping LAST_HIPRIORITY_VECTOR, but does mean that the
range FIRST-LAST_HIPRIORITY_VECTORs are free once again.

[PATCH 0 of 4] Prune outdated/impossible preprocessor symbols, and update VIOAPIC emulation
Patch 1 removes CONFIG_SMP
Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1
Patch 4 removes __ia64__ defines from the x86 arch tree
Patch 3 is related to patch 4 and changes the VIOAPIC to emulate
version 0x20 as a performance gain. It preceeds Patch 4 so as to be
more clear about the functional change.

[PATCH] arch/x86/kernel/apic/io_apic.c: Fix for crash when apic=debug is used
Hi,
Here is the patch fixing crash when apic=debug
is used and APIC is not properly initialized.
This issue appears during Xen Dom0 kernel boot
(git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git,
xen/stable-2.6.32.x head), however I think that
patch is rather generic and should be applied
to mainline kernel (it applies to Linux Kernel
Ver. 2.6.35 and Ver. 2.6.32.19 with small fuzz).

[PATCH] linux, S3: dom0 doesn''t need save ioapic state
Dom0 doesn''t need to save/restore ioapic state across S3
suspend/resume, as Xen already does it. The more important
is to avoid warnings on some platforms which may have
uninitialized RTEs to be weird value (like smi mode) but
masked. When dom0 saves those entries and then write back
later, it''s easy to trigger Xen''s sanity check from
ioapic_guest_write.

Grettings!
Dear colleagues,
I signed up for this list to learn more about CentOS and the language.
I ask you to understand me and help me to better understand the language
and the system.
For most phrases I'm using Google Translate but I've been struggling to
read and understand without it.

AMD IOMMU intremap tables and IOAPICs
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?

IO-APIC: tweak debug key info formatting
The formatting of the IO-APIC debug key info has niggled me for a while,
and with the latest interrupt bug I am chasing, has finally motivated me
to fix it.
The attached patch causes all columns to line up, and removes the comma
which served no purpose in combination with the spaces already present.

- Supports only level-triggered interrupts. Edge interrupts support
will be
added shortly (should be fairly simple)
- Change polarity trick: in order to reflect the external device''s

state, the ioapic pin gets its polarity changed whenever an

bootstrap resampling question
Hello there,
I have a problem concerning bootstrapping in R - especially focusing on the resampling part of it. I try to sum it up in a simplified way so that I would not confuse anybody.
I have a small database consisting of 20 observations (basically numbers from 1 to 20, I mean: 1, 2, 3, 4, 5, ... 18, 19, 20).
I would like to resample this database many times for the bootstrap process with

Hi all,
Since the last upgrade to firefox-60.5.0-2.el7.centos.x86_64 on my

always says that "Firefox is installing components needed to play the
audio or video on this page. Please try again later."
But nothing happens and Netflix is no longer readable with Firefox...
