address three issues in the intel_pstate driver and fix two problems related to hibernation.<\/p>\n<p>Specifics:<\/p>\n<p>- Make intel_pstate work correctly on Ice Lake server systems with out-of-band performance control enabled (Adamos Ttofari).<\/p>\n<p>- Fix EPP handling in intel_pstate during CPU offline and online in the active mode (Rafael Wysocki).<\/p>\n<p>- Make intel_pstate support ITMT on asymmetric systems with overclocking enabled (Srinivas Pandruvada).<\/p>\n<p>- Fix hibernation image saving when using the user space interface based on the snapshot special device file (Evan Green).<\/p>\n<p>- Make the hibernation code release the snapshot block device using the same mode that was used when acquiring it (Thomas Zeitlhofer)<\/p><\/blockquote>\n<p>\u5909\u66f4\u70b9\u306e\u8a73\u7d30\u306f<a
