[PATCH] ACPI: resource: Skip IRQ override on Asus Vivobook Go E1404GA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Like other Asus Vivobooks, the Asus Vivobook Go E1404GA has a DSDT
describing IRQ 1 as ActiveLow, while the kernel overrides to Edge_High.

    $ sudo dmesg | grep DMI:.*BIOS
    [    0.000000] DMI: ASUSTeK COMPUTER INC. Vivobook Go E1404GA_E1404GA/E1404GA, BIOS E1404GA.302 08/23/2023
    $ sudo cp /sys/firmware/acpi/tables/DSDT dsdt.dat
    $ iasl -d dsdt.dat
    $ grep -A 30 PS2K dsdt.dsl | grep IRQ -A 1
                IRQ (Level, ActiveLow, Exclusive, )
                    {1}

This override prevents the internal keyboard from working.

Fix the problem by adding this laptop to the table that prevents the
kernel from overriding the IRQ.
