[PATCH] tests: Silent various warnings with pseries


From: Greg Kurz
Subject: [PATCH] tests: Silent various warnings with pseries
Date: Sat, 01 Feb 2020 23:46:16 +0100
User-agent: StGit/unknown-version

Some default features of the pseries machine are only available with
KVM. Warnings are printed when the pseries machine is used with another
accelerator:

qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG
qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG
qemu-system-ppc64: warning: TCG doesn't support requested feature,
cap-ccf-assist=on
qemu-system-ppc64: warning: Firmware Assisted Non-Maskable
Interrupts(FWNMI) not supported in TCG

This is annoying for CI since it usually runs without KVM. We already
disable features that emit similar warnings thanks to properties of the
pseries machine, but this is open-coded in various places. Consolidate
the set of properties in a single place. Extend it to silent the above
warnings. And use it in the various tests that start pseries machines.

This patch fixes the warnings observed with David's latest pull request.
