Hi Graeme,
After some deep thoughts about introducing CONFIG_HARDWARE_REDUCED_ACPI, I think it is not a good idea to do that, so I drop this idea, and try to fix it as this patch did.
Comments are welcomed :)
ACPI spec states that fixed feature like ACPI specific registers do not fall within reduced profile. So each portion of ACPICA code that operate on ACPI specific hardware should be secured by: if (acpi_gbl_reduced_hardware) { return_ACPI_STATUS(AE_NOT_IMPLEMENTED); } IMHO, your patch does it in the right way. Bug should be reported to ACPICA along with this patch as solution proposal.
do you mean just send patches to ACPICA (not ACPI mailing list)? How can I report a bug to ACPICA, is there a bugzilla or something?
Yes, ACPICA has bugzilla: https://bugs.acpica.org/ Guys from Intel can review it more and upstream it on behalf of you.
