ACPI: add _PRT quirks to work around broken firmware
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.
