      pseries: Generate device paths for VIO devices · c4eda5b7
      由 David Gibson 提交于 
      This patch implements a get_dev_path qdev hook for the pseries paravirtual
VIO bus.  With upcoming savevm support, this will become very important for
scsi disks hanging of VIO virtual SCSI adapters.  scsibus_get_dev_path
uses the get_dev_path of the parent adapter if available, but otherwise
just uses a local channel/target/lun number to identify the device.  So if
two disks are present in the system having the same target and lun on
seperate VIO scsi adapters, savevm cannot distinguish them.  Since the
conventional way of using VSCSI adapters is to have just one disk per
adapter, such a conflict is very likely.

      pseries: Convert VIO code to QOM style type safe(ish) casts · fd506b4f
      由 David Gibson 提交于 
      Curerntly the pseries VIO device code contains quite a few explicit
uses of DO_UPCAST and plain C casts.  This is (obviously) type unsafe,
and not the conventional way of doing things in the QOM model.  This
patch converts the code to use the QOM convention of per-type macros
to do verified casts with OBJECT_CHECK().

      pseries: Fix some small errors in XICS logic · e03c902c
      由 David Gibson 提交于 
      Under certain circumstances the emulation for the pseries "XICS" interrupt
controller was clearing a pending interrupt from the XISR register, without
also clearing the corresponding priority variable.  This will cause
problems later when can trigger sanity checks in the under-development
in-kernel XICS implementation.

      pseries: Fixes and enhancements to L1 cache properties · 0cbad81f
      由 David Gibson 提交于 
      PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache.  We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).

We were also missing some of the required cache properties.  This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases).  We also
add the [id]-cache-size properties.

Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs.  The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against.  In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.

      PPC: mac newworld: fix cpu NIP reset value · 20f649dd
      由 Alexander Graf 提交于 
      On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.

This went unnoticed, because they used to boot at the same location our flash
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.

Set the initial IP to something reasonable for -M mac99.

      Enable kvm emulated watchdog · 31f2cb8f
      由 Bharat Bhushan 提交于 
      Enable the KVM emulated watchdog if KVM supports (use the
capability enablement in watchdog handler). Also watchdog exit
(KVM_EXIT_WATCHDOG) handling is added.
Watchdog state machine is cleared whenever VM state changes to running.
This is to handle the cases like return from debug halt etc.
