The spapr-pci PHB initializes IOMMU for emulataed devices only.
The upcoming VFIO support will do it different. However both emulated
and VFIO PHB types share most of the initialization code.
For the type specific things a new finish_realize() callback is
introduced.
This introduces sPAPRPHBClass

Hi, all
What's the difference of the linux guest kernel parameter

Taking the performance into account, which one is best?
In my opinion, if the number of all VMs' vcpus is far more than that of pcpus,
e.g. SPECVirt test, idle=halt is better for server's total

The OpenRISC architecture does not have its own move register
instruction. Instead it uses either "l.addi rd, r0, x" or
"l.ori rd, rs, 0" or "l.or rd, rx, r0"
The l.ori instruction is automatically optimized but not the l.addi instruction.
This patch optimizes for this spec

Yes. get_sbits returns a sign extended (32bit) int, the shift doesn't

The mtspr and mfspr routines didn't check for the correct memory boundaries.
This fixes a segmentation fault while booting Linux.

This patch corrects several misbehaviors during an interrupt process.
Most of the time the pc is already correct and therefore no special treatment
of the exceptions is necessary.
Tested by checking crashing programs which otherwise work in or1ksim.

The clock value is only evaluated when really necessary reducing
the overhead of the timer handling.
This also solves a problem in the way the Linux kernel
handles the timer and the expected accuracy.
The old version could lead to inaccurate timings.

Hi,
USB patch series from the ReduceWakeupRate department.
Patch #1 implements remote wakeup support to the ehci emulation.
Patch #2 reverts a workaround for lacking ehci remote wakeup
support in the highspeed version of the usb tablet.
Patches #3 + #4 are small preparations for #5.

This patch adds support for special usb descriptors used by microsoft
windows. They allow more fine-grained control over driver binding and
adding entries to the registry for configuration.

Don't run code in the signal handler, only set a flag.
Use sigaction(2) to avoid non-portable signal(2) semantics.
Make #ifdefs less messy.
