[PATCH v4 10/11] tests/acpi: unit test exercizing hotplug off for pci root bus & bridge in i440fx |
Date: |
Wed, 16 Sep 2020 11:43:34 +0530 |
This change adds a unit test to exercize the case when hotplug is disabled both
for
pci root bus and the pci bridges by passing the following two switches to qemu:
-global PIIX4_PM.acpi-root-pci-hotplug=off
-global PIIX4_PM.acpi-pci-hotplug-with-bridge-support=off
bios-tables-test-allowed-diff.h documents the fact that a new DSDT acpi gold
master
binary blob we need to be added to test this. We will do the actual addition in
the
next patch in the series.
The following link contains the disassembly of the DSDT table after passing the
above
two switches to qemu: https://pastebin.ubuntu.com/p/WvpYYjpPN8/
