- Document different semantics for ACPI_WMI_PROVIDES_GUID_STRING_METHOD acpi_wmi.c: - Modify acpi_wmi_provides_guid_string_method to return absolut number of instances known for the given GUID. acpi_hp.c: - sysctl dev.acpi_hp.0.verbose to toggle debug output - A modification so this can deal with different array lengths when reading the CMI BIOS - now it works ok on HP Compaq nx7300 as well. - Change behaviour to query only max_instance-1 CMI BIOS instances, because all HPs seen so far are broken in that respect (or there is a fundamental misunderstanding on my side, possible as well). This way a disturbing ACPI Error Field exceeds Buffer message is avoided. - New bit to set on dev.acpi_hp.0.cmi_detail (0x8) to also query the highest guid instance of CMI bios acpi_hp.4: - Document dev.acpi_hp.0.verbose sysctl in man page - Document new bit for dev.acpi_hp.0.cmi_detail - Add a section to manpage about hardware that has been reported to work ok Submitted by: Michael Gmelin, freebsdusb at bindone.de Approved by: re (kib) MFC after: 2 weeks
