cpufreq: intel_pstate: Update Balance-performance EPP for Granite Rapids

2024-11-13T11:59:02Z

Update EPP default for balance_performance to 32. This will give better performance out of the box using Intel P-State powersave governor while still offering power savings compared to performance governor. This is in line with what has already been done for Emerald Rapids and Sapphire Rapids.

cpufreq: maple: Remove maple driver

2024-11-13T01:02:23Z

This driver is no longer buildable since the PPC_MAPLE platform was removed, see commit 62f8f307c80e ("powerpc/64: Remove maple platform"). Remove the driver. Note that the comment in the driver says it supports "SMU & 970FX based G5 Macs", but that's not true, that comment was copied from pmac64-cpufreq.c, which still exists and continues to support those machines.

cpufreq: intel_pstate: Rearrange locking in hybrid_init_cpu_capacity_scaling()

2024-11-11T14:18:41Z

Notice that hybrid_init_cpu_capacity_scaling() only needs to hold hybrid_capacity_lock around __hybrid_init_cpu_capacity_scaling() calls, so introduce a "locked" wrapper around the latter and call it from the former. This allows to drop a local variable and a label that are not needed any more. Also, rename __hybrid_init_cpu_capacity_scaling() to __hybrid_refresh_cpu_capacity_scaling() for consistency. Interestingly enough, this fixes a locking issue introduced by commit 929ebc93ccaa ("cpufreq: intel_pstate: Set asymmetric CPU capacity on hybrid systems") that put an arch_enable_hybrid_capacity_scale() call under hybrid_capacity_lock, which was a mistake because the latter is acquired in CPU hotplug paths and so it cannot be held around cpus_read_lock() calls.
