* PNPACPI: use _CRS IRQ descriptor length for _SRSBjorn Helgaas2008-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When configuring the resources of an ACPI device, we first evaluate _CRS to get a template of resource descriptors, then fill in the specific resource values we want, and finally evaluate _SRS to actually configure the device. Some resources have optional fields, so the size of encoded descriptors varies depending on the specific values. For example, IRQ descriptors can be either two or three bytes long. The third byte contains triggering information and can be omitted if the IRQ is edge-triggered and active high. The BIOS often assumes that IRQ descriptors in the _SRS buffer use the same format as those in the _CRS buffer, so this patch enforces that constraint. The "Start Dependent Function" descriptor also has an optional byte, but we don't currently encode those descriptors, so I didn't do anything for those. I have tested this patch on a Toshiba Portege 4000. Without the patch, parport_pc claims the parallel port only if I use "pnpacpi=off". This patch makes it work with PNPACPI. This is an extension of a patch by Tom Jaeger: http://bugzilla.kernel.org/show_bug.cgi?id=9487#c42 References: http://bugzilla.kernel.org/show_bug.cgi?id=5832 Enabling ACPI Plug and Play in kernels >2.6.9 kills Parallel support http://bugzilla.kernel.org/show_bug.cgi?id=9487 buggy firmware expects four-byte IRQ resource descriptor (was: Serial port disappears after Suspend on Toshiba R25) http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=1d5b285da1893b90507b081664ac27f1a8a3dc5b related ACPICA fix Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
* pnpacpi: fix shareable IRQ encode/decodeBjorn Helgaas2008-06-11
| | | | | | | | | | | | When we encode IRQ resources, we should use the "shareable" flag we got from _PRS rather than guessing based on the IRQ trigger mode.

* pnpacpi: fix IRQ flag decodingBjorn Helgaas2008-06-11
| | | | | | | | | | | | | | | | | | | | | | | When decoding IRQ trigger mode and polarity, it is not enough to mask by IORESOURCE_BITS because there are now additional bits defined. For example, if IORESOURCE_IRQ_SHAREABLE was set, we failed to set *triggering and *polarity at all. I can't point to a failure that this patch fixes, but bugs in this area have caused problems when resuming after suspend, for example: http://bugzilla.kernel.org/show_bug.cgi?id=6316 http://bugzilla.kernel.org/show_bug.cgi?id=9487 https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/152187 This is based on a patch by Tom Jaeger: http://bugzilla.kernel.org/show_bug.cgi?id=9487#c32 [rene.herman@keyaccess.nl: fix comment] Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
* PNP: skip UNSET MEM resources as well as DISABLED onesBjorn Helgaas2008-06-05
| | | | | | | | | | | | | We don't need to reserve "unset" resources. Trying to reserve them results in messages like this, which are ugly but harmless: system 00:08: iomem range 0x0-0x0 could not be reserved Future PNP patches will remove use of IORESOURCE_UNSET, but we still need it for now.

* PNP: mark resources that conflict with PCI devices "disabled"Bjorn Helgaas2008-06-02
| | | | | | | | | | | | | | | Both the PNP/PCI conflict detection quirk and the PNP system driver must use the same mechanism to mark resources as disabled. I think it's best to keep the resource and to keep the type bit (IORESOURCE_MEM, etc), so that we match the list from firmware as closely as possible.

* Clean up 'print_fn_descriptor_symbol()' typesLinus Torvalds2008-05-15
| | | | | | | | | | | | Everybody wants to pass it a function pointer, and in fact, that is what you _must_ pass it for it to make sense (since it knows that ia64 and ppc64 use descriptors for function pointers and fetches the actual address from there). So don't make the argument be a 'unsigned long' and force everybody to add a cast. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* pnp: add ISAPnP MPU option quirksRene Herman2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but work fine without one. This adds (priority functional) IRQ-less options for each port option to help systems with few available IRQs. The AD1815 quirk can't use pnp_register_irq_resource() due to doubly penalizing the IRQ. Also, while not a practical issue due to no IRQ option being present for the dependents, this needs to add in front, not back. Doesn't use pnp_register_port_resource() for symetry with above. This does not delete the AD1815 independent option even though it should be empty after the IRQ transfer due to AD1816 coming with an empty but still present independent option by default. Was tested on AD1815, AD1816 and AZT2320. The ALSA snd-ad1818a driver also support the AZT2002 ID for MPU401 but this doesn't as I was unable to test it.

We need this because it is important to write ISAPNP configuration back to the same registers we read it from. For example, if we read valid regions from memory descriptors 0, 1, and 3, we'd better write them back to the same registers, without compressing them to descriptors 0, 1, and 2. This was previously guaranteed by using the index into the pnp_resource_table array as the ISAPNP config register index. However, I am removing those fixed-size arrays, so we need to save the ISAPNP register index elsewhere.

| | * PNP: remove unused interfaces using pnp_resource_tableBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rene Herman <rene.herman@gmail.com> recently removed the only in-tree driver uses of: pnp_init_resource_table() pnp_manual_config_dev() pnp_resource_change() in this change: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f These are no longer used in the PNP core either, so we can just remove them completely. It's possible that there are out-of-tree drivers that use these interfaces. They should be changed to either (1) use PNP quirks to work around broken hardware or firmware, or (2) use the sysfs interfaces to control resource usage from userspace.

| | * PNP: remove pnp_resource_table from internal pnp_clean_resource_table interfaceBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes pnp_clean_resource_table() to take a pnp_dev pointer rather than a pnp_resource_table pointer. This reduces the visibility of pnp_resource_table and removes an opportunity for error in the caller.

| | * PNP: add pnp_init_resources(struct pnp_dev *) interfaceBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pnp_init_resources(struct pnp_dev *) to replace pnp_init_resource_table(), which takes a pointer to the pnp_resource_table itself. Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.

| | * PNP: add debug when assigning PNP resourcesBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to dump PNP resources before and after assigning resources and before writing them to the device. This is enabled by CONFIG_PNP_DEBUG=y. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
| | * PNP: add debug output to encodersBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add debug output to encoders (enabled by CONFIG_PNP_DEBUG). This uses dev_printk, so I had to add pnp_dev arguments at the same time.

| | * PNP: remove more pnp_resource_table argumentsBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stop passing around struct pnp_resource_table pointers. In most cases, the caller doesn't need to know how the resources are stored inside the struct pnp_dev.

| | * PNP: remove pnp_resource_table from internal get/set interfacesBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we call protocol->get() and protocol->set() methods, we currently supply pointers to both the pnp_dev and the pnp_resource_table even though the pnp_resource_table should always be the one associated with the pnp_dev. This removes the pnp_resource_table arguments to make it clear that these methods only operate on the specified pnp_dev.
