In the ACPI DSDT table for Asus VivoBook K3402ZA/K3502ZA IRQ 1 is described as ActiveLow; however, the kernel overrides it to Edge_High. This prevents the internal keyboard from working on these laptops. In order to fix this add these laptops to the skip_override_table so that the kernel does not override IRQ 1 to Edge_High.

It has also been tested by myself on a K3502ZA and by someone else with a K3402ZA to verify that this patch allows the internal keyboard to work. drivers/acpi/resource.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/drivers/acpi/resource.c b/drivers/acpi/resource.c index 510cdec375c4..2ebc85233bac 100644 --- a/drivers/acpi/resource.c +++ b/drivers/acpi/resource.c @@ -399,6 +399,24 @@ static const struct dmi_system_id medion_laptop[] = { { } }; +static const struct dmi_system_id asus_laptop[] = { + { + .ident = "Asus Vivobook K3402ZA", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), + DMI_MATCH(DMI_BOARD_NAME, "K3402ZA"), + }, + }, + { + .ident = "Asus Vivobook K3502ZA", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), + DMI_MATCH(DMI_BOARD_NAME, "K3502ZA"), + }, + }, + { } +}; + struct irq_override_cmp { const struct dmi_system_id *system; unsigned char irq; @@ -409,6 +427,7 @@ struct irq_override_cmp { static const struct irq_override_cmp skip_override_table[] = { { medion_laptop, 1, ACPI_LEVEL_SENSITIVE, ACPI_ACTIVE_LOW, 0 }, + { asus_laptop, 1, ACPI_LEVEL_SENSITIVE, ACPI_ACTIVE_LOW, 0 }, }; static bool acpi_dev_irq_override(u32 gsi, u8 triggering, u8 polarity, -- 2.37.2
