We skip this section if COLO is not enabled (i.e.

ppc patch queue 2016-10-28

This pull request supersedes and extends the one from 2016-10-26
(which had a build bug).

Highlights:
  * SLOF (pseries guest firmware) update
  * Enable a number of extra testcases on ppc / pseries
  * Added the 'powernv' machine type
    - Almost enough to be minimally usable
    - But still missing necessary interrupt controller updates
  * Cleanup and consolidation of NVRAM handling on several platforms
    with related firmware
  * Substantial cleanup to device tree construction
  * Some more POWER9 instruction emulation
  * Cleanup to handling of pseries option vectors and CAS reboot
    handling (host/guest feature negotiation mechanism)
  * Significant cleanups to handling of PCI devices in test cases
  * New hotplug event infrastructure
  * Memory hot unplug support for pseries
  * Several bug fixes

The NVRAM cleanup affects some Sun sparc platforms as well as ppc
ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).

The test additions also include substantial general changes to the
test framework that aren't strictly ppc related.  They don't seem to
break tests on other platforms, they're for the benefit of enabling
tests on ppc and there isn't a specific maintainer for them, so
they're included in this tree.

GTK generates key events for the delete key with key->string[0] = 0x7f
... but this does not work right with the readline_handle_byte()
function in util/readline.c, since this treats the keycode 127 as
backspace. So let's add a special case for the GTK delete key to make
this key behave right in the monitor interface of the GTK ui.

ppc hypervisors have delivered system reset and machine check exception
interrupts to guests in some situations (e.g., see FWNMI feature of LoPAPR,
or NMI injection in QEMU).

These exceptions are architected to set the HV bit in hardware, however
when injected into a guest, the HV bit should be cleared. Current code
masks off the HV bit before setting the new MSR, however this happens after
the interrupt delivery model has calculated delivery mode for the exception.
This can result in the guest's MSR LE bit being lost.

Account for this in the exception handler and don't set HV bit for guest
delivery.

Also add another sanity check to ensure similar bugs get caught.

Commit 0a417869:

    spapr: Move memory hotplug to RTAS_LOG_V6_HP_ID_DRC_COUNT type

dropped per-DRC/per-LMB hotplugs event in favor of a bulk add via a
single LMB count value. This was to avoid overrunning the guest EPOW
event queue with hotplug events. This works fine, but relies on the
guest exhaustively scanning for pluggable LMBs to satisfy the
requested count by issuing rtas-get-sensor(DR_ENTITY_SENSE, ...) calls
until all the LMBs associated with the DIMM are identified.

With newer support for dedicated hotplug event source, this queue
exhaustion is no longer as much of an issue due to implementation
details on the guest side, but we still try to avoid excessive hotplug
events by now supporting both a count and a starting index to avoid
unecessary work. This patch makes use of that approach when the
capability is available.

This adds machine options of the form:

  -machine pseries,modern-hotplug-events=true
  -machine pseries,modern-hotplug-events=false

If false, QEMU will force the use of "legacy" style hotplug events,
which are surfaced through EPOW events instead of a dedicated
hot plug event source, and lack certain features necessary, mainly,
for memory unplug support.

If true, QEMU will enable support for "modern" dedicated hot plug
event source. Note that we will still default to "legacy" style unless
the guest advertises support for the "modern" hotplug events via
ibm,client-architecture-support hcall during early boot.

For pseries-2.7 and earlier we default to false, for newer machine
types we default to true.

Hotplug events were previously delivered using an EPOW interrupt
and were queued by linux guests into a circular buffer. For traditional
EPOW events like shutdown/resets, this isn't an issue, but for hotplug
events there are cases where this buffer can be exhausted, resulting
in the loss of hotplug events, resets, etc.

Newer-style hotplug event are delivered using a dedicated event source.
We enable this in supported guests by adding standard an additional
event source in the guest device-tree via /event-sources, and, if
the guest advertises support for the newer-style hotplug events,
using the corresponding interrupt to signal the available of
hotplug/unplug events.
