Debatable. "RETVAL < 0" is an idiomatic check for error. "RETVAL >= 0"
is merely its negation.
Why?
I figure the next patch wants it, but if that's the reason, the commit
message should state it.
implement secondary bus reset.

This patch isn't for 0.13 release. and for MST pci branch.
(git://git.kernel.org/pub/scm/linux/kernel/git/mst/qemu.git pci)
Patch description:
Introduce bus reset notion at qbus layer and implement pci bus reset
with it.
At first related codes are cleaned up and then introduce bus reset callback.
export pci_bus_reset() and pci_device_reset() for later use
with slight function signature adjustment.

Eliminate work around in pci_device_reset() by
making each pci reset function to call pci_device_reset_default().
Each device should know reset itself. It shouldn't be done pci generic
layer automatically. PCI layer should just signal reset and let each device
respond to reset.

The base address is a little strange
By your StackTrace.log, the base address, passed into smc91c111_init, is
0x40CC28C0. But this address should be 0x1001000, hard-coded in source code.

Hello
have you tried older versions of qemu, in an attempt to see if this is a
recent problem?
As of about a year ago I had qemu-sparc32plus running most of SPEC2006
properly, validated against hardware perf counters.
gcc definitely worked. I had issues with calculix, dealII, soplex, wrf,

Changing block.h or blockdev.h resulted in recompiling most objects.
Move DriveInfo typedef and BlockInterfaceType enum definitions
to qemu-common.h and rearrange blockdev.h use to decrease churn.

How do I get X86_FEATURE_ARCH_PERFMON enabled for a guest?
I've tried "-cpu host,+perfmon" and "-cpu host,+arch_perfmon", but both
get rejected with an error: CPU feature perfmon not found

I'm getting the same error with restoring an Acronis based image to KVM
