      hw/arm/armsse: Assert info->num_cpus is in-bounds in armsse_realize() · 3f410039
      由 Peter Maydell 提交于 
      In armsse_realize() we have a loop over [0, info->num_cpus), which
indexes into various fixed-size arrays in the ARMSSE struct.  This
confuses Coverity, which warns that we might overrun those arrays
(CID 1430326, 1430337, 1430371, 1430414, 1430430).  This can't
actually happen, because the info struct is always one of the entries
in the armsse_variants[] array and num_cpus is either 1 or 2; we also
already assert in armsse_init() that num_cpus is not too large.
However, adding an assert to armsse_realize() like the one in
armsse_init() should help Coverity figure out that these code paths
aren't possible.

      由 Peter Maydell 提交于 
      The doc-comments which document the qdev API are split between the
header file and the C source files, because as a project we haven't
been consistent about where we put them.

Move all the doc-comments in qdev.c to the header files, so that
users of the APIs don't have to look at the implementation files for
this information.

In the process, unify them into our doc-comment format and expand on
them in some cases to clarify expected use cases.

      Makefile: Remove config-devices.mak on "make clean" · d69cda7e
      由 Peter Maydell 提交于 
      The config-devices.mak files are generated by "make", and so they
should be deleted by "make clean".

(This is different from config-host.mak and config-all-disas.mak,
which are created by "configure" and so only deleted by
"make distclean".)

If we don't delete these files on "make clean", then the build
tree is left in a state where it has the config-devices.mak
file but not the config-devices.mak.d file, and make will not
realize that it needs to rebuild config-devices.mak if, for
instance, hw/sd/Kconfig changes.

NB: config-all-devices.mak is also generated by "make", but we
already remove it on "make clean".

      spapr: Add a new level of NUMA for GPUs · a6030d7e
      由 Reza Arbab 提交于 
      NUMA nodes corresponding to GPU memory currently have the same
affinity/distance as normal memory nodes. Add a third NUMA associativity
reference point enabling us to give GPU nodes more distance.

This is guest visible information, which shouldn't change under a
running guest across migration between different qemu versions, so make
the change effective only in new (pseries > 5.0) machine types.

Before, `numactl -H` output in a guest with 4 GPUs (nodes 2-5):

node distances:
node   0   1   2   3   4   5
  0:  10  40  40  40  40  40
  1:  40  10  40  40  40  40
  2:  40  40  10  40  40  40
  3:  40  40  40  10  40  40
  4:  40  40  40  40  10  40
  5:  40  40  40  40  40  10

After:

node distances:
node   0   1   2   3   4   5
  0:  10  40  80  80  80  80
  1:  40  10  80  80  80  80
  2:  80  80  10  80  80  80
  3:  80  80  80  10  80  80
  4:  80  80  80  80  10  80
  5:  80  80  80  80  80  10

These are the same distances as on the host, mirroring the change made
to host firmware in skiboot commit f845a648b8cb ("numa/associativity:
Add a new level of NUMA for GPU's").

      spapr_pci: Robustify support of PCI bridges · a4beb5f5
      由 Greg Kurz 提交于 
      Some recent error handling cleanups unveiled issues with our support of
PCI bridges:

1) QEMU aborts when using non-standard PCI bridge types,
   unveiled by commit 7ef1553d "spapr_pci: Drop some dead error handling"

$ qemu-system-ppc64 -M pseries -device pcie-pci-bridge
Unexpected error in object_property_find() at qom/object.c:1240:
qemu-system-ppc64: -device pcie-pci-bridge: Property '.chassis_nr' not found
Aborted (core dumped)

This happens because we assume all PCI bridge types to have a "chassis_nr"
property. This property only exists with the standard PCI bridge type
"pci-bridge" actually. We could possibly revert 7ef1553d but it seems
much simpler to check the presence of "chassis_nr" earlier.

2) QEMU abort if same "chassis_nr" value is used several times,
   unveiled by commit d2623129 "qom: Drop parameter @errp of
   object_property_add() & friends"

$ qemu-system-ppc64 -M pseries -device pci-bridge,chassis_nr=1 \
                        -device pci-bridge,chassis_nr=1
Unexpected error in object_property_try_add() at qom/object.c:1167:
qemu-system-ppc64: -device pci-bridge,chassis_nr=1: attempt to add duplicate property '40000100' to object (type 'container')
Aborted (core dumped)

This happens because we assume that "chassis_nr" values are unique, but
nobody enforces that and we end up generating duplicate DRC ids. The PCI
code doesn't really care for duplicate "chassis_nr" properties since it
is only used to initialize the "Chassis Number Register" of the bridge,
with no functional impact on QEMU. So, even if passing the same value
several times might look weird, it never broke anything before, so
I guess we don't necessarily want to enforce strict checking in the PCI
code now.

Workaround both issues in the PAPR code: check that the bridge has a
unique and non null "chassis_nr" when plugging it into its parent bus.

The Processor Service Interface Controller is an internal device.
It should only be instantiated by the chip, which takes care of
configuring the link required by the ICS object in the case of
POWER8. It doesn't make sense for a user to specify it on the
command line.

Note that the PSI model for POWER8 was added 3 yrs ago but the
devices weren't available on the command line because of a bug
that was fixed by recent commit 2f35254a ("pnv/psi: Correct
