| H A D | acpi_perf.c | diff 141824 Sun Feb 13 18:49:48 MST 2005 njl Add support for the CPUFREQ_FLAG_INFO_ONLY flag. Devices that report this are not added to the list(s) of available settings. However, other drivers can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to get info about available settings. Update the acpi_perf(4) driver to use this flag in the presence of "functional fixed hardware." Thus, future drivers like Powernow can query acpi_perf for platform info but perform frequency transitions themselves. |
