[PATCH for-6.2 v3 0/5] Fix Q35 ACPI PCI Hot-plug I/O issues |
Date: |

Changelog:
v3:
* drop unnecessary expected blobs
v2:
* simplify [1/5] and rename property to x-native-hotplug (CC stable)
* [4/5]
- rename function parameter to reflect actual action
- drop local 'hotplug' variable and opencode statement
* test with SeaBIOS/OVMF and Linux guest,
Windows also works with SeaBIOS, can't install it in EFI
mode on current master (it's stuck when formatting disk/or
copying files to hdd).
Attempt [1] to fix I/O allocation with the 'reserve-io' hint on each
pcie-root-port resulted in regression [2-3]. This patchset aims to fix
it by addressing the root cause of the problem - the disabled PCIe
Slot HPC bit.
This series enables PCIe Slot HPC bit which allows UEFI to enumerate and
initialize resources on ports, instead we hide PCIe hotplug capability in
host-bridge's ACPI _OSC method, which effectively make guest to use
ACPI based hotplug on host-bridge attached hierarchy.
