Merge tag 'pm-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki: "These add Intel TPMI (Topology Aware Register and PM Capsule Interface) support to the power capping subsystem, extend the intel_idle driver to work in VM guests where MWAIT is not available, extend the system-wide power management diagnostics, fix bugs and clean up code. Specifics: - Introduce power capping core support for Intel TPMI (Topology Aware Register and PM Capsule Interface) and a TPMI interface driver for Intel RAPL (Zhang Rui, Dan Carpenter) - Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping driver (Zhang Rui) - Fix invalid initialization for pl4_supported field in the Intel RAPL power capping driver (Sumeet Pawnikar) - Clean up the intel_idle driver, make it work with VM guests that cannot use the MWAIT instruction and address the case in which the host may enter a deep idle state when the guest is idle (Arjan van de Ven) - Prevent cpufreq drivers that provide the ->adjust_perf() callback without a ->fast_switch() one which is used as a fallback from the former in some cases (Wyes Karny) - Fix some issues related to the AMD P-state cpufreq driver (Mario Limonciello, Wyes Karny) - Fix the energy_performance_preference attribute handling in the intel_pstate driver in passive mode (Tero Kristo) - Fix the handling of pm_suspend_target_state when CONFIG_PM is unset (Kai-Heng Feng) - Correct spelling mistake in a comment in the hibernation code (Wang Honghui) - Add arch_resume_nosmt() prototype to avoid a "missing prototypes" build warning (Arnd Bergmann) - Restrict pm_pr_dbg() to system-wide power transitions and use it in a few additional places (Mario Limonciello) - Drop verification of in-params from genpd_add_device() and ensure that all of its callers will do it (Ulf Hansson) - Prevent possible integer overflows from occurring in genpd_parse_state() (Nikita Zhandarovich) - Reorder fieldls in 'struct devfreq_dev_status' to reduce its size somewhat (Christophe JAILLET) - Ensure that the Exynos PPMU driver is already loaded before the Exynos Bus driver starts probing so as to avoid a possible freeze loading of the kernel modules (Marek Szyprowski) - Fix variable deferencing before NULL check in the mtk-cci devfreq driver (Sukrut Bellary)" * tag 'pm-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (42 commits) intel_idle: Add a "Long HLT" C1 state for the VM guest mode cpufreq: intel_pstate: Fix energy_performance_preference for passive cpufreq: amd-pstate: Add a kernel config option to set default mode cpufreq: amd-pstate: Set a fallback policy based on preferred_profile ACPI: CPPC: Add definition for undefined FADT preferred PM profile value cpufreq: amd-pstate: Set default governor to schedutil PM: domains: Move the verification of in-params from genpd_add_device() cpufreq: amd-pstate: Make amd-pstate EPP driver name hyphenated cpufreq: amd-pstate: Write CPPC enable bit per-socket intel_idle: Add support for using intel_idle in a VM guest using just hlt cpufreq: Fail driver register if it has adjust_perf without fast_switch intel_idle: clean up the (new) state_update_enter_method function intel_idle: refactor state->enter manipulation into its own function platform/x86/amd: pmc: Use pm_pr_dbg() for suspend related messages pinctrl: amd: Use pm_pr_dbg to show debugging messages ACPI: x86: Add pm_debug_messages for LPS0 _DSM state tracking include/linux/suspend.h: Only show pm_pr_dbg messages at suspend/resume powercap: RAPL: Fix a NULL vs IS_ERR() bug powercap: RAPL: Fix CONFIG_IOSF_MBI dependency powercap: RAPL: fix invalid initialization for pl4_supported field ...
