Right, I figured that out now, actually I believe that with your hack to
drivers/acpi/resource.c the changes you made to drivers/base/platform.c
should no longer be necessary.
We've been looking at the wrong part of the DSDT the culprit is not:
Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, )
{
0x00000007,
}
This uses an extended interrupt syntax, so acpi_dev_get_irqresource() gets
called with legacy == false and the troublesome acpi_get_override_irq()
never happens.
I believe the real culprit is:
Scope (_SB.PCI0)
{
Device (SMBD)
{
Name (_HID, "SMB0001") // _HID: Hardware ID
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
IO (Decode16,
0x0B20, // Range Minimum
0x0B20, // Range Maximum
0x20, // Alignment
0x20, // Length
)
IRQ (Level, ActiveLow, Shared, )
{7}
})
}
}
Which does use a legacy style IRQ resource, this causes
acpi_dev_get_irqresource() to be called with legacy == true and then the
troublesome acpi_get_override_irq() happens.
I believe that this troublesome node gets parsed before the AMDI0030
node and then by the time the AMDI0030 node happens, inside
acpi_dev_get_irqresource() we hit the else of:
irq = acpi_register_gsi(NULL, gsi, triggering, polarity);
if (irq >= 0) {
res->start = irq;
res->end = irq;
} else {
acpi_dev_irqresource_disabled(res, gsi);
}
Which sets the DISABLED flag, which is causing the issue in
drivers/base/platform.c . The reason we hit the else path is because of
the earlier enumeration of the same interrupt with conflicting trigger /
polarity settings so the second one fails with -EBUSY (it would work if
the flags would match).
My new attempt deals with this by adding the "SMB0001" HID to the
blacklist for creating platform devices, so that
acpi_dev_get_resources() does not get called on it at all, avoiding the
call of acpi_dev_get_irqresource() with legacy == false.
The not creating of a platform_device for the "SMB0001" HID is not an
issue since the driver for it is an acpi bus driver not a platform bus
driver.
