2020-03-14T11:03:05Z

To make the code a bit more readable, let's move the OSI specific initialization out of the psci_dt_cpu_init_idle() and into a separate function. Reviewed-by: Sudeep Holla Signed-off-by: Ulf Hansson Signed-off-by: Rafael J. Wysocki

cpuidle: haltpoll: allow force loading on hosts without the REALTIME hint

2020-03-14T10:39:07Z

Before commit 1328edca4a14 ("cpuidle-haltpoll: Enable kvm guest polling when dedicated physical CPUs are available") the cpuidle-haltpoll driver could also be used in scenarios when the host does not advertise the KVM_HINTS_REALTIME hint. While the behavior introduced by the aforementioned commit makes sense as the default there are cases where the old behavior is desired, for example, when other kernel changes triggered by presence by this hint are unwanted, for some workloads where the latency benefit from polling overweights the loss from idle CPU capacity that otherwise would be available, or just when running under older Qemu versions that lack this hint. Let's provide a typical "force" module parameter that allows restoring the old behavior. Signed-off-by: Maciej S. Szmigiero Reviewed-by: Marcelo Tosatti Signed-off-by: Rafael J. Wysocki

cpuidle: tegra: Disable CC6 state if LP2 unavailable

2020-03-13T10:32:01Z

LP2 suspending could be unavailable, for example if it is disabled in a device-tree. CC6 cpuidle state won't work in that case. Acked-by: Peter De Schrijver Acked-by: Daniel Lezcano Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

cpuidle: tegra: Squash Tegra114 driver into the common driver

2020-03-13T10:32:01Z

Tegra20/30/114/124 SoCs have common idling states, thus there is no much point in having separate drivers for a similar hardware. This patch moves Tegra114/124 arch/ drivers into the common driver without any functional changes. The CC6 state is kept disabled on Tegra114/124 because the core Tegra PM code needs some more work in order to support that state.

cpuidle: tegra: Squash Tegra30 driver into the common driver

2020-03-13T10:32:01Z

Tegra20 and Terga30 SoCs have common C1 and CC6 idling states and thus share the same code paths, there is no point in having separate drivers for a similar hardware. This patch merely moves functionality of the old driver into the new, although the CC6 state is kept disabled for now since old driver had a rudimentary support for this state (allowing to enter into CC6 only when secondary CPUs are put offline), while new driver can provide a full-featured support. The new feature will be enabled by another patch.
