  hw/ide: Emulate SiI3112 SATA controller (2017-12-19 15:24:28 +1100)

----------------------------------------------------------------
ppc patch queue 2017-12-19

Here's a second batch of patches for qemu-2.12.  Highlights are:

  * Optional capabilities for the "pseries" machine.  This removes
    some places where we were changing guest visible properties based
    on host capabilities, which makes life very bad for migration.
  * SLOF update
  * Significant TCG speedup from Paolo
  * Several new devices for embedded platforms
  * Some minor cleanups

----------------------------------------------------------------
Alexey Kardashevskiy (1):
      pseries: Update SLOF firmware image to qemu-slof-20171214

BALATON Zoltan (4):
      sm501: Add panel hardware cursor registers also to read function
      sm501: Add some more unimplemented registers
      ppc4xx_i2c: Implement basic I2C functions
      hw/ide: Emulate SiI3112 SATA controller

Cédric Le Goater (1):
      ppc/pnv: change powernv_ prefix to pnv_ for overall naming consistency

David Gibson (6):
      spapr: Capabilities infrastructure
      spapr: Treat Hardware Transactional Memory (HTM) as an optional capability
      spapr: Validate capabilities on migration
      target/ppc: Clean up probing of VMX, VSX and DFP availability on KVM
      spapr: Handle VMX/VSX presence as an spapr capability flag
      spapr: Handle Decimal Floating Point (DFP) as an optional capability

Greg Kurz (1):
      spapr_pci: use warn_report()

pbonzini@redhat.com (1):
      target-ppc: optimize cmp translation

Process 4041/4042 are using 100% CPU.

$ QTEST_QEMU_BINARY=ppc64-softmmu/qemu-system-ppc64 gtester -k
--verbose -m=quick tests/migration-test
TEST: tests/migration-test... (pid=5441)
  /ppc64/migration/postcopy/unix:
[hangs]

My first guess is that this is a general 32-bit host issue
rather than an arm-host specific one; arm just happens to
be the only 32-bit system in my test set.

thanks

Oh :(.  I ran make check SPEED=slow in a 32-bit x86 container before
sending the pull request, and I just retried it now, so that doesn't
appear to be the case.

I haven't the foggiest what could be broken in an arm host specific
way, though.  Nor do I have easy access to an arm system to track it
down on.

After I sent that I remembered my Raspberry Pi.  Unfortunately, after
spending most of the day getting it compiled, I wasn't able to
reproduce the problem.  The migration-test completed just fine with my
ppc-for-2.12 tree.

I'm not sure where to go from here, I don't even have a guess as to
which patch in the series might be causing the problem, since none of
them seem likely candidates.

I can have another look with the setup that failed, but that won't be
until the new year, I'm afraid.
