Rafal Bilski 52a2638bff Longhaul: add auto enabled "revid_errata" option ... VIA C3 Ezra-T has RevisionID equal to 1, but it needs RevisionKey to be 0 or CPU will ignore new frequency and will continue to work at old frequency. New "revid_errata" option will force RevisionKey to be set to 0, whatever RevisionID is. Additionaly "Longhaul" will not silently ignore unsuccessful transition. It will try to check if "revid_errata" or "disable_acpi_c3" options need to be enabled for this processor/system. Same for Longhaul ver. 2 support. It will be disabled if none of above options will work. Best case scenario (with patch apllied and v2 enabled): longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v2 supported. longhaul: Using northbridge support. longhaul: VRM 8.5 longhaul: Max VID=1.350 Min VID=1.050, 13 possible voltage scales longhaul: f: 300000 kHz, index: 0, vid: 1050 mV [...] longhaul: Voltage scaling enabled. Worst case scenario: longhaul: VIA C3 'Ezra-T' [C5M] CPU detected. Powersaver supported. longhaul: Using northbridge support. longhaul: Using ACPI support. longhaul: VRM 8.5 longhaul: Claims to support voltage scaling but min & max are both 1.250. Voltage scaling disabled longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Disabling ACPI C3 support. longhaul: Disabling "Ignore Revision ID" option. longhaul: Failed to set requested frequency! longhaul: Enabling "Ignore Revision ID" option.
