[Qemu-devel] [PATCH v3 0/6] tests: Add device unplug tests

From: David Hildenbrand
Subject: [Qemu-devel] [PATCH v3 0/6] tests: Add device unplug tests
Date: Mon, 18 Feb 2019 10:21:56 +0100

This is a set of tests to test basic device unplugging functionality for
- some PCI implementations
- CCW devices on s390x
- spapr memory and cpu core devices

I plaed with ACPI CPU unplug but getting that to run with qtest is more
involved. (remove devices on reset, trick cpu-hotplug-legacy property,
somehow create cpu hotplug state objects ...). Well we no have at least
one unplug test for DIMMs and one for CPUs.

v2 -> v3:
- Use a smaller DIMM for spapr memory unplug request test
- Combine both spapr test registrations in a single if statement
- Use "-" instead of "_" in test names
- Add a huge load of r-b/a-b :) hpe I didn't forget some.

v1 -> v2:
- Tests for CCW, spapr memory and spapr cpu core unplug added
- Fix a deadlock when unplugging dummy CPUs
- Style fixes / simplifications (Thomas)
- Don't use the global_qtest variable (Thomas)
- Fix double-free (Greg)

David Hildenbrand (6):
  cpus: Properly release the iothread lock when killing a dummy VCPU
  spapr: support memory unplug for qtest
  tests/device-plug: Add a simple PCI unplug request test
  tests/device-plug: Add CCW unplug test for s390x
  tests/device-plug: Add CPU core unplug request test for spapr
  tests/device-plug: Add memory unplug request test for spapr
