If BIOS invokes _OSI(Linux), the kernel response depends on what the ACPI DMI list knows about the system, and that is reflectd in dmesg: 1) System unknown to DMI: ACPI: BIOS _OSI(Linux) query ignored ACPI: DMI System Vendor: LENOVO ACPI: DMI Product Name: 7661W1P ACPI: DMI Product Version: ThinkPad T61 ACPI: DMI Board Name: 7661W1P ACPI: DMI BIOS Vendor: LENOVO ACPI: DMI BIOS Date: 10/18/2007 ACPI: Please send DMI info above to linux-acpi@vger.kernel.org ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org 2) System known to DMI, but effect of OSI(Linux) unknown: ACPI: DMI detected: Lenovo ThinkPad T61 ... ACPI: BIOS _OSI(Linux) query ignored via DMI ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org 3) System known to DMI, which disables _OSI(Linux): ACPI: DMI detected: Lenovo ThinkPad T61 ... ACPI: BIOS _OSI(Linux) query ignored via DMI 4) System known to DMI, which enable _OSI(Linux): ACPI: DMI detected: Lenovo ThinkPad T61 ACPI: Added _OSI(Linux) ... ACPI: BIOS _OSI(Linux) query honored via DMI cmdline overrides take precidence over the built-in default and the DMI prescribed default. cmdline "acpi_osi=Linux" results in: ACPI: BIOS _OSI(Linux) query honored via cmdline Signed-off-by: Len Brown <len.brown@intel.com> |
