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: Skip IRQ override on ASUS ExpertBook B1402CBA

2023-09-18T18:48:27+00:00

Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CBA
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: 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.

ACPI: resource: Always use MADT override IRQ settings for all legacy non i8042 IRQs

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

All the cases, were the DSDT IRQ settings should be used instead of
the MADT override, are for IRQ 1 or 12, the PS/2 kbd resp. mouse IRQs.

Simplify things by always honering the override for other legacy IRQs
(for non DMI quirked cases).

This allows removing the DMI quirks to honor the override for
some non i8042 IRQs on some AMD ZEN based Lenovo models.

ACPI: resource: revert "Remove "Zen" specific match and quirks"

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

Commit a9c4a912b7dc ("ACPI: resource: Remove "Zen" specific match and
quirks") is causing keyboard problems for quite a log of AMD based
laptop users, leading to many bug reports.

Revert this change for now, until we can come up with
a better fix for the PS/2 IRQ trigger-type/polarity problems
on some x86 laptops.

ACPI: resource: Remove "Zen" specific match and quirks

2023-06-05T17:20:33+00:00

commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on
AMD Zen platforms") attempted to overhaul the override logic so it
didn't apply on X86 AMD Zen systems.  This was intentional so that
systems would prefer DSDT values instead of default MADT value for
IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1.

This turned out to be a bad assumption because several vendors
add Interrupt Source Override but don't fix the DSDT. A pile of
quirks was collecting that proved this wasn't sustaintable.

Furthermore some vendors have used ActiveHigh for IRQ1.
To solve this problem revert the following commits:
* commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang
GMxRGxx")
* commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7")
* commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
* commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15")
* commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen
platforms")

ACPI: resource: Skip IRQ override on ASUS ExpertBook B1502CBA

2023-04-11T18:52:19+00:00

Like the ASUS ExpertBook B2502CBA and various ASUS Vivobook laptops, the
ASUS ExpertBook B1502CBA has an ACPI DSDT table that describes IRQ 1 as
ActiveLow while the kernel overrides it to Edge_High.

    $ sudo dmesg | grep DMI
    DMI: ASUSTeK COMPUTER INC. ASUS EXPERTBOOK B1502CBA_B1502CBA/B1502CBA, BIOS B1502CBA.300 01/18/2023
    $ 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.
