ACPI: resource: Skip IRQ override on ASUS ExpertBook B1502CGA

2024-01-09T14:20:48+00:00

Like the ASUS ExpertBook B1502CBA and various ASUS laptops, the
ASUS ExpertBook B1502CGA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.

	$ sudo dmesg | grep DMI
	[    0.000000] DMI: ASUSTeK COMPUTER INC. 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.

ACPI: resource: Add DMI quirks for ASUS Vivobook E1504GA and E1504GAB

2024-01-09T14:05:54+00:00

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.

ACPI: resource: Add Infinity laptops to irq1_edge_low_force_override

2024-01-03T19:47:58+00:00

A user reported a keyboard problem similar to ones reported with other
Zen laptops, on an Infinity E15-5A165-BM.

Add board name matches for this model and one (untested) close relative
to irq1_edge_low_force_override.

ACPI: resource: Add another DMI match for the TongFang GMxXGxx

2023-12-29T17:44:58+00:00

The TongFang GMxXGxx, which needs IRQ overriding for the keyboard to work,
is also sold as the Eluktronics RP-15 which does not use the standard
TongFang GMxXGxx DMI board_name.

Add an entry for this laptop to the irq1_edge_low_force_override[] DMI
table to make the internal keyboard functional.

ACPI: resource: Do IRQ override on TongFang GMxXGxx

2023-10-26T10:27:36+00:00

The TongFang GMxXGxx/TUXEDO Stellaris/Pollaris Gen5 needs IRQ overriding
for the keyboard to work.

Adding an entry for this laptop to the override_table makes the internal

ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to irq1_edge_low_force_override[]

2023-10-09T12:56:29+00:00

The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.

The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.

Adjust the pcspecialist_laptop[] DMI match table for this:

1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
   entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
   the laptop when sold by other vendors such as hyperbook.pl.

2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
   models.

Note the .ident values of the dmi_system_id structs are left unset
since these are not used.

The dmi_system_id.ident values are not used, replace the

ACPI: resource: Consolidate IRQ trigger-type override DMI tables

2023-09-18T18:48:37+00:00

Before this patch there were 6 dmi_system_id tables. While looking at
the override_table[] there are only 2 cases:

 1. irq 1, level, active-low, not-shared, skip-override
 2. irq 1, edge, activ-low, shared, force-override

Merge the dmi_system_id tables for identical cases together,
going from 6 dmi_system_id tables and 6 override_table[] entries
to just 2, one for each case.
