one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.
- 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
