For power on, this is just like ipmi.
For power off, it doesn't mind errors (although it has three
attempts). This is useful when combined with pdu power: if the
chassis power is already off, ipmi will fail.
If the ipmi operation does fail, then the chassing pdu power operation
will do the job.
And, an abbreviation for invoking it: just writing numbers (or
/ pair of numbers).

Dom0 (aka hardware domain on Arm) is always direct mapped. Rather than
using a global variable to store a const, directly open-code it or
replace the use with is_domain_direct_mapped(...) macros.
This will also help a follow-up patch to move all domain_build.c in

The code has been around since the beginning of Xen Arm. However, I am
not aware of any user and the code is pretty bogus:
1) It is assuming virtual address == physical address.
2) The cache is not cleaned after the Image is loaded but the Image
is started with Cache disabled.
3)

This series removes unused code from Xen and also move some part under __init

This is a good question indeed.

This patch adds access rights for the NPT pages. The access rights are
saved in a radix tree with the root saved in p2m_domain. The rights are
manipulated through p2m_set_access()
and p2m_get_access() functions.
The patch follows the ept logic.
Note: It was tested with
These MSRs are non-architectural and the available booleans were used in lieu
of an architectural signal of availability.
However, in hindsight, the additional booleans make toolstack MSR interactions
more complicated. The MSRs are unconditionally available to HVM guests, but

Hi All,
PCI-PT and PCI config space emulation have been in discussion for quite
a long time.
We had started some work on this in past and in LEG-XEN but that didnt
go far and the group is closed.
I believe that PCI-PT is a feature which would be suitable for not only
for servers but for

Setting pv_irq_ops for Xen PV domains should be done as early as
possible in order to support e.g. very early printk() usage.
Remove the no longer necessary conditional in xen_init_irq_ops()
from PVH V1 times to make clear this is a PV only function.

When removing the global bit from __supported_pte_mask do the same for
__default_kernel_pte_mask in order to avoid the WARN_ONCE() in
check_pgprot() when setting a kernel pte before having called

This simplifies future interactions with the toolstack, by removing the need
for per-MSR custom accessors when shuffling data in/out of a policy.
Use a 32bit raw backing integer (for simplicity), and use a bitfield to move
the cpuid_faulting field to its appropriate position.

This is further cleanup work to help the forthcoming toolstack CPUID/MSR work.
Andrew Cooper (3):
tools/libxc: Drop xc_cpuid_to_str()
x86/msr: Drop {MISC_ENABLES,PLATFORM_INFO}.available
x86/msr: Use the architectural layout for MSR_{MISC_ENABLES,PLATFORM_INFO}
These MSRs are non-architectural and the available booleans were used in lieu
of an architectural signal of availability. The MSRs are unconditionally
available to HVM guests, but currently for PV guests, are hidden when CPUID
faulting is unavailable.
However, in hindsight, the additional

alloc_str() is actually an opencoded calloc(), and now only has a single
caller. Use calloc() directly and drop alloc_str().
