Linux/ACPI core files using internal.h all PREFIX "ACPI: ",
however, not all ACPI drivers use/want it -- and they
should not have to #undef PREFIX to define their own.Add GPL commment to internal.h while we are there.
This does not change any actual console output,
asside from a whitespace fix.Signed-off-by: Len Brown

There is no need to pass a segment/bus tuple to this API, as the callsite
always has a struct pci_bus. We can derive segment/bus from the
struct pci_bus, so let's take this opportunit to simplify the API and
make life easier for the callers.Signed-off-by: Alex Chiang

A PCI domain cannot change as you descend down subordinate buses, which
makes the 'segment' argument to acpi_pci_irq_add_prt() useless.Change the interface to take a struct pci_bus *, from whence we can derive
the bus number and segment. Reducing the number of arguments makes life
simpler for callers.Signed-off-by: Alex Chiang

This doesn't change anything functionally; it just changes tests

We currently pass a callback function (either acpi_pci_allocate_irq() or
acpi_pci_free_irq()) to acpi_pci_irq_lookup() and acpi_pci_irq_derive().I think it's simpler to remove the callback and just have the enable/
disable functions make the calls directly.Signed-off-by: Bjorn Helgaas

There's no reason to pass around segment, bus, and device independently
when we can just pass the pci_dev pointer, which carries all those
already.The pci_dev contains an interrupt pin, too, but we still have to pass both
the pci_dev and the pin because when we use a bridge to derive an IRQ, we
need the pin from the downstream device, not the bridge.Signed-off-by: Bjorn Helgaas

Use the PCI INTx pin encoding (1=INTA, 2=INTB, etc) for _PRT quirks.
Then we can simply compare "entry->pin == quirk->pin".Signed-off-by: Bjorn Helgaas
Signed-off-by: Len Brown -
This patch changes pci_irq.c to always use PCI INTx pin encodings
instead of a mix of PCI and _PRT encodings.The PCI INTx pin numbers from the PCI_INTERRUPT_PIN config register
are 0=device doesn't use interrupts, 1=INTA, ..., 4=INTD. But the
_PRT table uses 0=INTA, ..., 3=INTD.This patch converts the _PRT encoding to the PCI encoding immediately
when we add a _PRT entry to the global list. All the rest of the
code can then use the PCI encoding consistently.The point of this is to make the interrupt swizzling look the same
as on other architectures, so someday we can unify them.Signed-off-by: Bjorn Helgaas

_PRT entries don't contain any useful PCI function information (the

Previously, acpi_pci_irq_add_prt() did all its own buffer management.
But now that we have ACPI_ALLOCATE_BUFFER, we no longer need to do
that management. And we don't have to call acpi_get_irq_routing_table()
twice (once to learn the size of the buffer needed, and again to
actually get the table).Signed-off-by: Bjorn Helgaas

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The
BIOS reports the interrupt routing incorrectly. I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything. We need ".ISA_." instead.Thank you Johann-Nikolaus Andreae
for patiently testing this patch.See http://bugzilla.kernel.org/show_bug.cgi?id=4773

This patch works around incorrect _PRT (PCI interrupt routing)
information from firmware. This does not fix any regressions
and can wait for the next kernel release.On the Medion MD9580-F laptop, the BIOS says the builtin RTL8139
NIC interrupt at 00:09.0[A] is connected to \_SB.PCI0.ISA.LNKA, but
it's really connected to \_SB.PCI0.ISA.LNKB. Before this patch,
the workaround was to use "pci=routeirq". More details at
http://bugzilla.kernel.org/show_bug.cgi?id=4773.On the Dell OptiPlex GX1, the BIOS says the PCI slot interrupt
00:0d[A] is connected to LNKB, but it's really connected to LNKA.
Before this patch, the workaround was to use "pci=routeirq".
Pierre Ossman tested a previous version of this patch and confirmed
that it fixed the problem. More details at
http://bugzilla.kernel.org/show_bug.cgi?id=5044.On the HP t5710 thin client, the BIOS says the builtin Radeon
video interrupt at 01:00[A] is connected to LNK1, but it's really
connected to LNK3. The previous workaround was to use a custom
DSDT. I tested this patch and verified that it fixes the problem.
