Hi All,
As discussed here in the v1 thread: https://lore.kernel.org/linux-acpi/20230806151453.10690-1-hdegoede@redhat.co...
Here is a v2 which adds a few fixes on top of the revert to avoid the revert causing regressions on AMD Zen systems where dropping the special Zen behavior was known to fix things.
As also mentioned in the thread this is intended as a short term fix for 6.4.y >= 6.4.7 and 6.5 to get all the systems which were working fine before commit a9c4a912b7dc ("ACPI: resource: Remove "Zen" specific match and quirks") to work again.
The long term plan is to see if we can read back what the BIOS has actually programmed as IRQ trigger-type / polarity into the IOAPIC.
Regards,
Hans
