ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CVA

2023-11-20T16:43:59+00:00

Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CVA
has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
the kernel overrides it to EdgeHigh.

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: 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
keyboard functional.

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.

ACPI: resource: Drop .ident values from dmi_system_id tables

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

The dmi_system_id.ident values are not used, replace the
.ident = "$ident" lines with /* $ident */ to drop the unused strings
from the text section.

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.

ACPI: resource: Fix IRQ override quirk for PCSpecialist Elimina Pro 16 M

2023-08-21T10:48:52+00:00

It turns out that some PCSpecialist Elimina Pro 16 M models
have "GM6BGEQ" as DMI product-name instead of "Elimina Pro 16 M",
causing the existing DMI quirk to not work on these models.

The DMI board-name is always "GM6BGEQ", so match on that instead.

ACPI: resource: Add IRQ override quirk for PCSpecialist Elimina Pro 16 M

2023-08-10T14:45:26+00:00

The PCSpecialist Elimina Pro 16 M laptop model is a Zen laptop which
needs to use the MADT IRQ settings override and which does not have
an INT_SRC_OVR entry for IRQ 1 in its MADT.

So this model needs a DMI quirk to enable the MADT IRQ settings override
to fix its keyboard not working.

ACPI: resource: Honor MADT INT_SRC_OVR settings for IRQ1 on AMD Zen

2023-08-09T19:18:46+00:00

On AMD Zen acpi_dev_irq_override() by default prefers the DSDT IRQ 1
settings over the MADT settings.

This causes the keyboard to malfunction on some laptop models
(see Links), all models from the Links have an INT_SRC_OVR MADT entry
for IRQ 1.
