[PATCH v3] platform/x86/intel-uncore-freq: Fix missing uncore sysfs during CPU hotplug

by shouyeliu

From: Shouye Liu <shouyeliu(a)tencent.com> In certain situations, the sysfs for uncore may not be present when all CPUs in a package are offlined and then brought back online after boot. This issue can occur if there is an error in adding the sysfs entry due to a memory allocation failure. Retrying to bring the CPUs online will not resolve the issue, as the uncore_cpu_mask is already set for the package before the failure condition occurs. This issue does not occur if the failure happens during module initialization, as the module will fail to load in the event of any error. To address this, ensure that the uncore_cpu_mask is not set until the successful return of uncore_freq_add_entry().

[PATCH] platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles

by Mario Limonciello

From: Mario Limonciello <mario.limonciello(a)amd.com> When an APU exits HW sleep with no active wake sources the Linux kernel will rapidly assert that the APU can enter back into HW sleep. This happens in a few ms. Contrasting this to Windows, Windows can take 10s of seconds to enter back into the resiliency phase for Modern Standby. For some situations this can be problematic because it can cause leakage from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical design guide specifications. On some designs this will trip the over voltage protection feature (OVP) of the voltage regulator module, but it could cause APU damage as well. To prevent this risk, add an explicit sleep call so that future attempts to enter into HW sleep will have enough time to settle. This will occur while the screen is dark and only on cases that the APU should enter HW sleep again, so it shouldn't be noticeable to any user.

In practice, this fixes the call to mmu_notifier_arch_invalidate_secondary_tlbs() in __flush_tlb_range_nosync() to use the correct range instead of an empty range with start=end. The empty range was (un)lucky as it results in taking the invalidate-all path that doesn't cause correctness issues, but can certainly result in suboptimal perf. This has been broken since commit 6bbd42e2df8f ("mmu_notifiers: call invalidate_range() when invalidating TLBs") when the call to the notifiers was added to __flush_tlb_range(). It predates the addition of the __flush_tlb_range_op() macro from commit 360839027a6e ("arm64: tlb: Refactor the core flush algorithm of __flush_tlb_range") that made the bug hard to spot.

It should not be used at all on Orin NX/Nano. Having this unused pin mapped as the suspend key can lead to unpredictable behavior for low power modes. Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend" button. However, we cannot have two gpio-keys mapped to the same GPIO. Therefore remove the "suspend" key.
