+ USB Type-C Specification defines a cable and connector for USB where
+ only one type of plug is supported on both ends, i.e. there will not
+ be Type-A plug on one end of the cable and Type-B plug on the other.
+ Determination of the host-to-device relationship happens through a
+ specific Configuration Channel (CC) which goes through the USB Type-C
+ cable. The Configuration Channel may also be used to detect optional
+ Accessory Modes - Analog Audio and Debug - and if USB Power Delivery
+ is supported, the Alternate Modes, where the connector is used for
+ something else then USB communication.
-config TYPEC
- tristate
+ USB Power Delivery Specification defines a protocol that can be used
+ to negotiate the voltage and current levels with the connected
+ partners. USB Power Delivery allows higher voltages then the normal
+ 5V, up to 20V, and current up to 5A over the cable. The USB Power
+ Delivery protocol is also used to negotiate the optional Alternate
+ Modes when they are supported. USB Power Delivery does not depend on
+ USB Type-C connector, however it is mostly used together with USB
+ Type-C connectors.
+
+ USB Type-C and USB Power Delivery Specifications define a set of state
+ machines that need to be implemented in either software or firmware.
+ Simple USB Type-C PHYs, for example USB Type-C Port Controller
+ Interface Specification compliant "Port Controllers" need the state
+ machines to be handled in the OS, but stand-alone USB Type-C and Power
+ Delivery controllers handle the state machines inside their firmware.
+ The USB Type-C and Power Delivery controllers usually function
+ autonomously, and do not necessarily require drivers.
+
+ Enable this configurations option if you have USB Type-C connectors on
+ your system and 1) you know your USB Type-C hardware requires OS
+ control (a driver) to function, or 2) if you need to be able to read
+ the status of the USB Type-C ports in your system, or 3) if you need
+ to be able to swap the power role (decide are you supplying or
+ consuming power over the cable) or data role (host or device) when
+ both roles are supported.
+

- * the _rcu list-traversal primitives, such as
- * hlist_nulls_for_each_entry_rcu(), used to prevent memory-consistency
- * problems on Alpha CPUs. Regardless of the type of CPU, the

+ * rq itself is runnable anywhere between 2/3 and 1 depending on how the
+ * runnable section of these tasks overlap (or not). If they were to perfectly
+ * align the rq as a whole would be runnable 2/3 of the time. If however we
+ * always have at least 1 runnable task, the rq as a whole is always runnable.
*
+ * So we'll have to approximate.. :/
*
- * Another way to look at things is:
+ * Given the constraint:
*
- * grq->avg.load_avg = \Sum se->avg.load_avg
+ * ge->avg.running_sum <= ge->avg.runnable_sum <= LOAD_AVG_MAX
*
- * Therefore, per (2):
+ * We can construct a rule that adds runnable to a rq by assuming minimal
+ * overlap.
*
- * grq->avg.load_avg = \Sum se->load.weight * se->avg.runnable_avg
+ * On removal, we'll assume each task is equally runnable; which yields:
*
- * And the very thing we're propagating is a change in that sum (someone
- * joined/left). So we can easily know the runnable change, which would be, per
- * (2) the already tracked se->load_avg divided by the corresponding
- * se->weight.
+ * grq->avg.runnable_sum = grq->avg.load_sum / grq->load.weight
*
- * Basically (4) but in differential form:
+ * XXX: only do this for the part of runnable > running ?
*
- * d(runnable_avg) += se->avg.load_avg / se->load.weight
- * (5)
- * ge->avg.load_avg += ge->load.weight * d(runnable_avg)
