2021-10-21mmc: dw_mmc: Drop use of ->init_card() callbackUlf Hansson
For dw_mmc, the ->init_card() callback is being used to turn on/off automatic internal clock gating for powersave, which is needed to properly support SDIO irqs on DAT1. However, using the ->init_card() comes with a drawback in this case, as it means that the powersave feature becomes disabled, no matter whether the SDIO irqs becomes turned on or not. To improve the behaviour, let's change into using the ->enable_sdio_irq() callback instead. This works fine, because dw_mmc uses sdio_signal_irq() to signal the irqs, thus the ->enable_sdio_irq() is never executed from within atomic context.

2021-10-21mmc: sdhci-omap: Fix build if CONFIG_PM_SLEEP is not setTony Lindgren
Commit f433e8aac6b9 ("mmc: sdhci-omap: Implement PM runtime functions") combined the use of runtime PM and system suspend functions but left the ifdef CONFIG_PM_SLEEP in place causing undeclared identifier error for sdhci_omap_runtime_suspend if CONFIG_PM_SLEEP is not enabled. Let's fix the error by removing ifdef CONFIG_PM_SLEEP and tagging the reset of the PM related functions with __maybe_unused. Let's also remove the forward declaration for sdhci_omap_context_save(), that was accidentally left from an earlier version and is no longer used.

2021-10-21platform/x86: amd-pmc: Add special handling for timer based S0i3 wakeupMario Limonciello
RTC based wakeup from s0i3 doesn't work properly on some Green Sardine platforms. Because of this, a newer SMU for Green Sardine has the ability to pass wakeup time as argument of the upper 16 bits of OS_HINT message. With older firmware setting the timer value in OS_HINT will cause firmware to reject the hint, so only run this path on: 1) Green Sardine 2) Minimum SMU FW 3) RTC alarm armed during s0i3 entry Using this method has some limitations that the s0i3 wakeup will need to be between 4 seconds and 18 hours, so check those boundary conditions as well and abort the suspend if RTC is armed for too short or too long of a duration.

2021-10-21blk-crypto: rename blk_keyslot_manager to blk_crypto_profileEric Biggers
blk_keyslot_manager is misnamed because it doesn't necessarily manage keyslots. It actually does several different things: - Contains the crypto capabilities of the device. - Provides functions to control the inline encryption hardware. Originally these were just for programming/evicting keyslots; however, new functionality (hardware-wrapped keys) will require new functions here which are unrelated to keyslots. Moreover, device-mapper devices already (ab)use "keyslot_evict" to pass key eviction requests to their underlying devices even though device-mapper devices don't have any keyslots themselves (so it really should be "evict_key", not "keyslot_evict"). - Sometimes (but not always!) it manages keyslots. Originally it always did, but device-mapper devices don't have keyslots themselves, so they use a "passthrough keyslot manager" which doesn't actually manage keyslots. This hack works, but the terminology is unnatural. Also, some hardware doesn't have keyslots and thus also uses a "passthrough keyslot manager" (support for such hardware is yet to be upstreamed, but it will happen eventually). Let's stop having keyslot managers which don't actually manage keyslots. Instead, rename blk_keyslot_manager to blk_crypto_profile. This is a fairly big change, since for consistency it also has to update keyslot manager-related function names, variable names, and comments -- not just the actual struct name. However it's still a fairly straightforward change, as it doesn't change any actual functionality.

2021-10-21thermal/core: Deprecate changing cooling device state from userspaceDaniel Lezcano
The cooling devices have their cooling device set_cur_state read-writable all the time in the sysfs directory, thus allowing the userspace to act on it. The thermal framework is wrongly used by userspace as a power capping framework by acting on the cooling device opaque state. This one then competes with the in-kernel governor decision. We have seen in out-of-tree kernels, a big number of devices which are abusely declaring themselves as cooling device just to act on their power. The role of the thermal framework is to protect the junction temperature of the silicon. Letting the userspace to play with a cooling device is invalid and potentially dangerous. The powercap framework is the right framework to do power capping and moreover it deals with the aggregation via the dev pm qos. As the userspace governor is marked deprecated and about to be removed, there is no point to keep this file writable also in the future. Emit a warning and deprecate the interface.

2021-10-21thermal/core: Make the userspace governor deprecatedDaniel Lezcano
The userspace governor is sending temperature when polling is active and trip point crossed events. Nothing else. AFAICT, this governor is used with custom kernels making the userspace governor co-existing with another governor on the same thermal zone because there was no notification mechanism, implying a hack in the framework to support this configuration. The new netlink thermal notification is able to provide more information than the userspace governor and give the opportunity to the users of this governor to replace it by a dedicated notification framework. The userspace governor will be removed as its usage is no longer needed. Add a warning message to tell the userspace governor is deprecated.

That gives very gross power estimation and we can do much better by using the load to scale the power consumption. Use the utilization to normalize and scale the power usage over the max possible power. Tested on a rock960 with 2 big CPUS, the power consumption estimation conforms with the expected one.

2021-10-21powercap/drivers/dtpm: Use container_of instead of a private data fieldDaniel Lezcano
The dtpm framework provides an API to allocate a dtpm node. However when a backend dtpm driver needs to allocate a dtpm node it must define its own structure and store the pointer of this structure in the private field of the dtpm structure. It is more elegant to use the container_of macro and add the dtpm structure inside the dtpm backend specific structure. The code will be able to deal properly with the dtpm structure as a generic entity, making all this even more self-encapsulated. The dtpm_alloc() function does no longer make sense as the dtpm structure will be allocated when allocating the device specific dtpm structure. The dtpm_init() is provided instead.

2021-10-21powercap/drivers/dtpm: Encapsulate even more the codeDaniel Lezcano
In order to increase the self-encapsulation of the dtpm generic code, the following changes are adding a power update ops to the dtpm ops. That allows the generic code to call directly the dtpm backend function to update the power values. The power update function does compute the power characteristics when the function is invoked. In the case of the CPUs, the power consumption depends on the number of online CPUs. The online CPUs mask is not up to date at CPUHP_AP_ONLINE_DYN state in the tear down callback. That is the reason why the online / offline are at separate state. As there is already an existing state for DTPM, this one is only moved to the DEAD state, so there is no addition of new state with these changes. The dtpm node is not removed when the cpu is unplugged. That simplifies the code for the next changes and results in a more self-encapsulated code.
