Hi Anthony,
Can you provide more details on why you want to expose internal APIs
in the library class?
What is the specific issue? Is the Local APIC in your environment
not behaving the same as real HW?
Thanks,
Mike

HorizontalResolution and VerticalResolution are 32bit, while size is
64bit. As it stands the multiplication is evaluated with 32bit
arithmetic, which could overflow. Cast HorizontalResolution to 64bit to
avoid that.

This patch relocates mem_access components that are currently mixed with p2m
code into separate files. This better aligns the code with similar subsystems,
such as mem_sharing and mem_paging, which are already in separate files. There

__get_page_type(), so far using an on-stack CPU mask variable, is
involved in the recursion when e.g. pinning page tables. This means
there may be up two five instances of the function active at a time,

variable. With an IRQ happening

Hi,
I've started to create a Xen specifig plaform, in OvmfPkg/XenOvmf.dsc
with the goal to make it work on both Xen HVM and Xen PVHv2
The first few patches only create the platform and duplicate some code from
OvmfPkg and the later patches (from OvmfPkg/XenPlatformPei: Add xen PVH
specific code)
and add OvmfPkg/XenConsoleIo/XenConsoleIo to XenOvmf platform.
It actually look for gEfiSerialIoProtocolGuid.

Copy of OvmfPkg/ResetVector, with one changes:
- default_cr0: enable cache
Xen copy the OVMF code to RAM, there is no need for cache. Also, it
makes OVMF slow to start on AMD.

With this, how much of the new code could be shared between
Google's fuzzer and AFL, for which George had put this togeth

Mind adding some description here on how this is expected to work /
be used? The new Makefile produce an object file and an archive,
but no binary, so it's not clear to me what u

Dario,
analyzing a stack overflow I've run into the other day I came across
credit1's __runq_tickle() not only itself having two cpumask_t
variables on the stack, but then also calling cpumask_raise_softirq()
(which uses yet one more). I then recalled you have a scratch mask
in the scheduler, and
flight 68176 distros-debian-wheezy real [real]
http://osstest.xs.citrite.net/~osstest/testlogs/logs/68176/
Perfect :-)
All tests in this flight passed as required
baseline version:
flight 68133
jobs:
build-amd64 pass
build-armh
flight 103011 linux-4.1 real [real]
http://logs.test-lab.xenproject.org/osstest/logs/103011/
Regressions :-(
Tests which did not succeed and are blocking,
including tests which could not be run:
test-amd64-amd64-xl-qemuu-winxpsp3 6 xen-boot fail REGR. vs. 101737
test-amd64-amd64-xl
elf_uval() can return zero either because the field itself is zero, or because
the access is out of bounds.
c/s a01b6d4 "libelf: treat phdr and shdr similarly" introduced two div0 issues
as e_{ph,sh}entsize are not checked for sanity before being used to divide
elf->size.
