genpd_syscore_switch() had two problems: 1. It silently assumed that device, it is being called for, belongs to generic power domain and used container_of() on its power domain pointer. Such assumption might not be true always. 2. It iterated over list of generic power domains without holding gpd_list_lock mutex thus list could have been modified at the same time. Usage of genpd_lookup_dev() solves both problems as it is safe a call for non-generic power domains and uses mutex when iterating. Reported-by:

When an IRQ safe device is attached to a no sleep domain, genpd prints a warning once, as to indicate it is a suboptimal configuration from power consumption point of view. However the warning doesn't make sense for an always on domain, since it anyway remains powered on. Therefore, let's change to not print the warning for this configuration. Signed-off-by:

The current code in genpd_sync_power_off(), doesn't care about potential errors being returned from genpd's ->power_off() callback. Obviously this behaviour could lead to problems, such as incorrectly setting the genpd's status to GPD_STATE_POWER_OFF, but also to incorrectly decrease the subdomain count for the masters, which potentially allows them to be powered off in the next recursive call to genpd_sync_power_off(). Let's fix this behaviour by bailing out when the ->power_off() callback returns an error code. Signed-off-by:

Ulf Hansson authored
The current way to implement an always on PM domain consists of returning -EBUSY from the ->power_off() callback. This is a bit different compared to using the always on genpd governor, which prevents the PM domain from being powered off via runtime suspend, but not via system suspend. The approach to return -EBUSY from the ->power_off() callback to support always on PM domains in genpd is suboptimal. That is because it requires genpd to follow the regular execution path of the power off sequence, which ends by invoking the ->power_off() callback. To enable genpd to early abort the power off sequence for always on PM domains, it needs static information about these configurations. Therefore let's add a new genpd configuration flag, GENPD_FLAG_ALWAYS_ON. Users of the new GENPD_FLAG_ALWAYS_ON flag, are by genpd required to make sure the PM domain is powered on before calling pm_genpd_init(). Moreover, users don't need to implement the ->power_off() callback, as genpd doesn't ever invoke it. Signed-off-by:

This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug. Signed-off-by:

The SSN bears a one- to-one relationship to the MSN returned by the responder in each re- sponse packet.
