From d2aaf19965045f70bb2ece514399cdc6fcce2e73 Mon Sep 17 00:00:00 2001 From: Ben Mayo Date: Sat, 6 Jan 2024 21:13:23 -0500 Subject: ACPI: resource: Add DMI quirks for ASUS Vivobook E1504GA and E1504GAB Asus Vivobook E1504GA and E1504GAB notebooks are affected by bug #216158 (DSDT specifies the kbd IRQ as level active-low and using the override changes this to rising edge, stopping the keyboard from working). Users of these notebooks do not have a working keyboard unless they add their DMI information to the struct irq1_level_low_skip_override array and compile a custom kernel. Add support for these computers to the Linux kernel without requiring the end-user to recompile the kernel.

ASUS EXPERTBOOK B1502CGA_B1502CGA/B1502CGA, BIOS B1502CGA.303 06/05/2023 $ grep -A 40 PS2K dsdt.dsl | grep IRQ -A 1 IRQ (Level, ActiveLow, Exclusive, ) {1} This prevents the keyboard from working. To fix this issue, add this laptop to the skip_override_table so that the kernel does not override IRQ 1.
