* 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>

This message will still be seen without "quiet", but a lot of messages are printed in that mode and it will be less likely to cause undue alarm.
