2008-07-17ACPI: use dev_printk when possibleBjorn Helgaas1-21/+17
Convert printks to use dev_printk(). The most obvious change will be messages like this: -ACPI: PCI Interrupt 0000:00:04.0[A] -> GSI 31 (level, low) -> IRQ 31 +cciss 0000:00:04.0: PCI INT A -> GSI 31 (level, low) -> IRQ 31 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>
2008-07-08pci, acpi: reroute PCI interrupt to legacy boot interrupt equivalentStefan Assmann1-0/+56
Some chipsets (e.g. intel 6700PXH) generate a legacy INTx when the IRQ entry in the chipset's IO-APIC is masked (as, e.g. the RT kernel does during interrupt handling). On chipsets where this INTx generation cannot be disabled, we reroute the valid interrupts to their legacy equivalent to get rid of spurious interrupts that might otherwise bring down (vital) interrupt lines through spurious interrupt detection in note_interrupt(). This patch benefited from discussions with Alexander Graf, Torsten Duwe, Ihno Krumreich, Daniel Gollub, Hannes Reinecke. The conclusions we drew and the patch itself are the authors' responsibility alone.

2008-03-26ACPI: fix Medion _PRT quirk (use "ISA_", not "ISA")Bjorn Helgaas1-2/+2
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 <johann-nikolaus.andreae@nacs.de> for patiently testing this patch.

2008-03-12ACPI: add _PRT quirks to work around broken firmwareBjorn Helgaas1-0/+98
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. More details at http://bugzilla.kernel.org/show_bug.cgi?id=10138.

2005-12-10[ACPI] ACPICA 20050930Bob Moore1-24/+24
Completed a major overhaul of the Resource Manager code - specifically, optimizations in the area of the AML/internal resource conversion code. The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate(). Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
