This was intentional so that +systems would prefer DSDT values instead of default MADT value for +IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1. + +This turned out to be a bad assumption because several vendors +add Interrupt Source Override but don't fix the DSDT. A pile of +quirks was collecting that proved this wasn't sustaintable. + +Furthermore some vendors have used ActiveHigh for IRQ1. +To solve this problem revert the following commits: +* commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang +GMxRGxx") +* commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7") +* commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad") +* commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15") +* commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen +platforms") + +Reported-by: evilsnoo@proton.me +Link: https://bugzilla.kernel.org/show_bug.cgi?id=217394 +Reported-by: ruinairas1992@gmail.com +Link: https://bugzilla.kernel.org/show_bug.cgi?id=217406 +Reported-by: nmschulte@gmail.com +Link: https://bugzilla.kernel.org/show_bug.cgi?id=217336 +Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> +Tested-by: Werner Sembach <wse@tuxedocomputers.com> +Tested-by: Chuanhong Guo <gch981213@gmail.com> +Signed-off-by: Rafael J.
