Changes in v3: - Add links to more bug reports caused by a9c4a912b7dc to the commitmsg - Also do the ZEN check for IRQ 12 (Reported-by August Wikerfors) - Move the gsi != 1 && gsi != 12 check to inside the #ifdef CONFIG_X86, these being the i8042 IRQs is X86 specific and the "return true;" is always done for #ifndef CONFIG_X86 already - Make acpi_int_src_ovr an array which keep track of the status of all legacy IRQs and not just IRQ 1 Changes in v2: - Add 2 patches on top of the revert to avoid the revert causing other models which are known to need the override to regress. As discussed in the v1 thread: https://lore.kernel.org/linux-acpi/20230806151453.10690-1-hdegoede@redhat.com/ This series adds a few fixes on top of the revert to avoid the revert causing regressions on other 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.
