commit bd911485294a6f0596e4592ed442438015cffc8a upstream.
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.

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 PCSpecialist Elimina Pro 16 M laptop model is a Zen laptop which

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).

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")

IRQ override isn't needed on modern AMD Zen systems.
There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay
this way on newer platforms. This IRQ override breaks keyboards for
almost all Ryzen 6000 laptops currently on the market.
Skip this IRQ override for all AMD Zen platforms because this IRQ
override is supposed to be a workaround for buggy ACPI DSDT and we can't
have a long list of all future AMD CPUs/Laptops in the kernel code.
If a device with buggy ACPI DSDT shows up, a separated list containing
just them should be created.

The laptop keyboard doesn't work on many MEDION notebooks, but the
keyboard works well under Windows and Unix.
Through debugging, we found this log in the dmesg:
ACPI: IRQ 1 override to edge, high
pnp 00:03: Plug and Play ACPI device, IDs PNP0303 (active)
And we checked the IRQ definition in the DSDT, it is:
IRQ (Level, ActiveLow, Exclusive, )
{1}
So the BIOS defines the keyboard IRQ to Level_Low, but the Linux
kernel override it to Edge_High. If the Linux kernel is modified
to skip the IRQ override, the keyboard will work normally.
From the existing comment in acpi_dev_get_irqresource(), the override
function only needs to be called when IRQ() or IRQNoFlags() is used
to populate the resource descriptor, and according to Section 6.4.2.1
of ACPI 6.4 [1], if IRQ() is empty or IRQNoFlags() is used, the IRQ
is High true, edge sensitive and non-shareable. ACPICA also assumes
that to be the case (see acpi_rs_set_irq[] in rsirq.c).
In accordance with the above, check 3 additional conditions
(EdgeSensitive, ActiveHigh and Exclusive) when deciding whether or
not to treat an ACPI_RESOURCE_TYPE_IRQ resource as "legacy", in which
case the IRQ override is applicable to it.

This reverts commit 8a66790b7850a6669129af078768a1d42076a0ef.
Switching this function to AE_CTRL_TERMINATE broke the documented
behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in
fact, terminate the resource walk because acpi_walk_resource_buffer()
ignores it (specifically converting it to AE_OK), referring to that
value as "an OK termination by the user function". This means that
acpi_dev_get_resources() does not abort processing when the preproc
function returns a negative value.

Some devices have limited addressing capabilities and cannot
reference the whole memory address space while carrying out DMA
operations (eg some devices with bus address bits range smaller than
system bus - which prevents them from using bus addresses that are
otherwise valid for the system).
The ACPI _DMA object allows bus devices to define the DMA window that is
actually addressable by devices that sit upstream the bus, therefore
providing a means to parse and initialize the devices DMA masks and
addressable DMA range size.
By relying on the generic ACPI kernel layer to retrieve and parse
resources, introduce ACPI core code to parse the _DMA object.

The function acpi_dev_get_resources() is completely generic and
can be used to parse resource objects that are not necessarily
coming from the _CRS method but also from other objects eg _DMA
that have the same _CRS resource format.
Create an acpi_dev_get_resources() helper, internal to the ACPI
resources parsing compilation unit, __acpi_dev_get_resources(),
that takes a const char* parameter to detect which ACPI method should be
called to retrieve the resources list and make acpi_dev_get_resources()
call it with a method name _CRS leaving the API behaviour unchanged.

ACPI extended IRQ resources may contain a Resource Source field to specify
an alternate interrupt controller, attempting to map them as GSIs is
incorrect, so just disable the platform resource.
Since this field is currently ignored, we make this change conditional
on CONFIG_ACPI_GENERIC_GSI to keep the current behavior on x86 platforms,
in case some existing ACPI tables are using this incorrectly.

Add acpi_resource_consumer(). This takes a struct resource and searches
the ACPI namespace for a device whose current resource settings (_CRS)
includes the resource. It returns the device if it exists, or NULL if no
device uses the resource.
If more than one device uses the resource (this may happen in the case of
bridges), acpi_resource_consumer() returns the first one found by
acpi_get_devices() in its modified depth-first walk of the namespace.

The [0 - 64k] ACPI PCI IO port resource boundary check in:
acpi_dev_ioresource_flags()
is currently applied blindly in the ACPI resource parsing to all
architectures, but only x86 suffers from that IO space limitation.
On arches (ie IA64 and ARM64) where IO space is memory mapped,
the PCI root bridges IO resource windows are firstly initialized from
the _CRS (in acpi_decode_space()) and contain the CPU physical address
at which a root bridge decodes IO space in the CPU physical address
space with the offset value representing the offset required to translate
the PCI bus address into the CPU physical address.
The IO resource windows are then parsed and updated in arch code
before creating and enumerating PCI buses (eg IA64 add_io_space())
to map in an arch specific way the obtained CPU physical address range
to a slice of virtual address space reserved to map PCI IO space,
ending up with PCI bridges resource windows containing IO
resources like the following on a working IA64 configuration:
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [io 0x1000000-0x100ffff window] (bus
address [0x0000-0xffff])
pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000fffff window]
pci_bus 0000:00: root bus resource [mem 0x80000000-0x8fffffff window]
pci_bus 0000:00: root bus resource [mem 0x80004000000-0x800ffffffff window]
pci_bus 0000:00: root bus resource [bus 00]
This implies that the [0 - 64K] check in acpi_dev_ioresource_flags()
leaves platforms with memory mapped IO space (ie IA64) broken (ie kernel
can't claim IO resources since the host bridge IO resource is disabled
and discarded by ACPI core code, see log on IA64 with missing root bridge
IO resource, silently filtered by current [0 - 64k] check in
acpi_dev_ioresource_flags()):
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000fffff window]
pci_bus 0000:00: root bus resource [mem 0x80000000-0x8fffffff window]
pci_bus 0000:00: root bus resource [mem 0x80004000000-0x800ffffffff window]
pci_bus 0000:00: root bus resource [bus 00]
[...]
pci 0000:00:03.0: [1002:515e] type 00 class 0x030000
pci 0000:00:03.0: reg 0x10: [mem 0x80000000-0x87ffffff pref]
pci 0000:00:03.0: reg 0x14: [io 0x1000-0x10ff]
pci 0000:00:03.0: reg 0x18: [mem 0x88020000-0x8802ffff]
pci 0000:00:03.0: reg 0x30: [mem 0x88000000-0x8801ffff pref]
pci 0000:00:03.0: supports D1 D2
pci 0000:00:03.0: can't claim BAR 1 [io 0x1000-0x10ff]: no compatible
bridge window
For this reason, the IO port resources boundaries check in generic ACPI
parsing code should be guarded with a CONFIG_X86 guard so that more arches
(ie ARM64) can benefit from the generic ACPI resources parsing interface
without incurring in unexpected resource filtering, fixing at the same
time current breakage on IA64.
This patch factors out IO ports boundary [0 - 64k] check in generic ACPI
code and makes the IO space check X86 specific to make sure that IO
space resources are usable on other arches too.
