It should be driver's responsibility to clear the interrupt before issuing EOI.

If we start Windows 2008 R2 DataCenter with number of cpu less than 8,
The system will use APIC Flat Logical destination mode as default configuration,
Which has an upper limit of 8 CPUs.
The fault is that VM can not show all processors within Task Manager if

PowerPC TCG flushes the TLB on every IR/DR change, which basically
means on every user<->kernel context switch. Use the 6-element
TLB array as a cache, where each MMU index is mapped to a different
state of the IR/DR/PR/HV bits.
This brings the number of TLB flushes down from ~90 to ~5
fo
The MMU index is an internal detail that should not be
needed by the translator. Look at the MSR directly.

Hi everyone,
these patches provide a speedup around 20% when running PPC softmmu
emulation on x86 machines (10% for user-mode emulation). There are
actually two separate speedups here:
* avoiding TLB flushing on every kernel<->user transition (patches 1-2)
* rewriting CR handling to use 32 1-bi

Most of the time, guest vector operations are rare enough that it doesn't
really matter that we implement them with a loop around integer operations.
But for target-alpha, there's one vector comparison operation that appears in
every guest string operation, and is used heavily enough that it's in

Although s390-virtio won't support memory hotplug, it should
enforce the same memory boundaries so that it can use shared codepaths
(like read_SCP_info).

When determining the memory increment size, use the maxmem size if
it was specified.

This patchset adds support in s390 for a pool of standby memory,
which can be set online/offline by the guest (ie, via chmem).
The standby pool of memory is allocated as the difference between
the initial memory setting and the maxmem setting.
As part of this work, additional results are provided

userfaultfd is a Linux syscall that gives an fd that receives a stream
of notifications of accesses to pages marked as MADV_USERFAULT, and
allows the program to acknowledge those stalls and tell the accessing
thread to carry on.
