* lib: create common ascii hex arrayHarvey Harrison2008-05-14
| | | | | | | | | | | | | | | | | Add a common hex array in hexdump.c so everyone can use it. Add a common hi/lo helper to avoid the shifting masking that is done to get the upper and lower nibbles of a byte value. Pull the pack_hex_byte helper from kgdb as it is opencoded many places in the tree that will be consolidated.

* 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.

* pnp: add pnp_build_option() to the APIRene Herman2008-05-14
| | | | | | | | | | | | | | | | The subsequent AD181x quirk patch would like this as part of the API. pnp_register_dependent_option() adds to the same dependent chain the quirk is walking which is fairly unclean. This enables a private option chain build which it can then just add onto the end when done.

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.

I split this out because it changes the behavior slightly: we used to check for conflicts only with earlier resources, e.g., we checked resource 2 against resources 0 and 1 but not against 3, 4, etc. Now we will check against all resources except 2. Since resources are assigned in ascending order, the old behavior was probably safe, but I don't like to depend on that ordering.

| | * PNP: add debug output to option registrationBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add debug output to resource option registration functions (enabled by CONFIG_PNP_DEBUG). This uses dev_printk, so I had to add pnp_dev arguments at the same time.

| | * PNPACPI: pass pnp_dev instead of acpi_handleBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass the pnp_dev pointer when possible instead of the acpi_handle. This allows better error messages and reduces the chance of error in the caller.

| | * PNPACPI: extend irq_flags() to set IORESOURCE_IRQ_SHAREABLE when appropriateBjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies IRQ resource parsing slightly by computing all the IORESOURCE_IRQ_* flags at the same time. This also keeps track of shareability information when parsing options from _PRS. Previously we ignored shareability in _PRS.

| | * PNPACPI: hoist dma_flags() out of pnpacpi_parse_allocated_dmaresource()Bjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hoist dma_flags() out of pnpacpi_parse_allocated_dmaresource() into its caller. This makes pnpacpi_parse_allocated_dmaresource() more similar to pnpbios_parse_allocated_dmaresource().

| | * PNPACPI: pnpacpi_encode_ext_irq() wrongly set "irq" instead of "extended_irq"Bjorn Helgaas2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pnpacpi_encode_ext_irq() should set resource->data.extended_irq, not resource->data.irq. This has been wrong since at least 2.6.12. I haven't seen any bug reports, but it's clearly incorrect. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
