+Cluster-wide Power-up/power-down race avoidance algorithm
+=========================================================
+
+This file documents the algorithm which is used to coordinate CPU and
+cluster setup and teardown operations and to manage hardware coherency
+controls safely.
+
+The section "Rationale" explains what the algorithm is for and why it is
+needed.  "Basic model" explains general concepts using a simplified view
+of the system.  The other sections explain the actual details of the
+algorithm in use.
+
+
+Rationale
+---------
+
+In a system containing multiple CPUs, it is desirable to have the
+ability to turn off individual CPUs when the system is idle, reducing
+power consumption and thermal dissipation.
+
+In a system containing multiple clusters of CPUs, it is also desirable
+to have the ability to turn off entire clusters.
+
+Turning entire clusters off and on is a risky business, because it
+involves performing potentially destructive operations affecting a group
+of independently running CPUs, while the OS continues to run.  This
+means that we need some coordination in order to ensure that critical
+cluster-level operations are only performed when it is truly safe to do
+so.
+
+Simple locking may not be sufficient to solve this problem, because
+mechanisms like Linux spinlocks may rely on coherency mechanisms which
+are not immediately enabled when a cluster powers up.  Since enabling or
+disabling those mechanisms may itself be a non-atomic operation (such as
+writing some hardware registers and invalidating large caches), other
+methods of coordination are required in order to guarantee safe
+power-down and power-up at the cluster level.
+
+The mechanism presented in this document describes a coherent memory
+based protocol for performing the needed coordination.  It aims to be as
+lightweight as possible, while providing the required safety properties.
+
+
+Basic model
+-----------
+
+Each cluster and CPU is assigned a state, as follows:
+
+	DOWN
+	COMING_UP
+	UP
+	GOING_DOWN
+
+	    +---------> UP ----------+
+	    |                        v
+
+	COMING_UP                GOING_DOWN
+
+	    ^                        |
+	    +--------- DOWN <--------+
+
+
+DOWN:	The CPU or cluster is not coherent, and is either powered off or
+	suspended, or is ready to be powered off or suspended.
+
+COMING_UP: The CPU or cluster has committed to moving to the UP state.
+	It may be part way through the process of initialisation and
+	enabling coherency.
+
+UP:	The CPU or cluster is active and coherent at the hardware
+	level.  A CPU in this state is not necessarily being used
+	actively by the kernel.
+
+GOING_DOWN: The CPU or cluster has committed to moving to the DOWN
+	state.  It may be part way through the process of teardown and
+	coherency exit.
+
+
+Each CPU has one of these states assigned to it at any point in time.
+The CPU states are described in the "CPU state" section, below.
+
+Each cluster is also assigned a state, but it is necessary to split the
+state value into two parts (the "cluster" state and "inbound" state) and
+to introduce additional states in order to avoid races between different
+CPUs in the cluster simultaneously modifying the state.  The cluster-
+level states are described in the "Cluster state" section.
+
+To help distinguish the CPU states from cluster states in this
+discussion, the state names are given a CPU_ prefix for the CPU states,
+and a CLUSTER_ or INBOUND_ prefix for the cluster states.
+
+
+CPU state
+---------
+
+In this algorithm, each individual core in a multi-core processor is
+referred to as a "CPU".  CPUs are assumed to be single-threaded:
+therefore, a CPU can only be doing one thing at a single point in time.
+
+This means that CPUs fit the basic model closely.
+
+The algorithm defines the following states for each CPU in the system:
+
+	CPU_DOWN
+	CPU_COMING_UP
+	CPU_UP
+	CPU_GOING_DOWN
+
+	 cluster setup and
+	CPU setup complete          policy decision
+	      +-----------> CPU_UP ------------+
+	      |                                v
+
+	CPU_COMING_UP                   CPU_GOING_DOWN
+
+	      ^                                |
+	      +----------- CPU_DOWN <----------+
+	 policy decision           CPU teardown complete
+	or hardware event
+
+
+The definitions of the four states correspond closely to the states of
+the basic model.
+
+Transitions between states occur as follows.
+
+A trigger event (spontaneous) means that the CPU can transition to the
+next state as a result of making local progress only, with no
+requirement for any external event to happen.
+
+
+CPU_DOWN:
+
+	A CPU reaches the CPU_DOWN state when it is ready for
+	power-down.  On reaching this state, the CPU will typically
+	power itself down or suspend itself, via a WFI instruction or a
+	firmware call.
+
+	Next state:	CPU_COMING_UP
+	Conditions:	none
+
+	Trigger events:
+
+		a) an explicit hardware power-up operation, resulting
+		   from a policy decision on another CPU;
+
+		b) a hardware event, such as an interrupt.
+
+
+CPU_COMING_UP:
+
+	A CPU cannot start participating in hardware coherency until the
+	cluster is set up and coherent.  If the cluster is not ready,
+	then the CPU will wait in the CPU_COMING_UP state until the
+	cluster has been set up.
+
+	Next state:	CPU_UP
+	Conditions:	The CPU's parent cluster must be in CLUSTER_UP.
+	Trigger events:	Transition of the parent cluster to CLUSTER_UP.
+
+	Refer to the "Cluster state" section for a description of the
+	CLUSTER_UP state.
+
+
+CPU_UP:
+	When a CPU reaches the CPU_UP state, it is safe for the CPU to
+	start participating in local coherency.
+
+	This is done by jumping to the kernel's CPU resume code.
+
+	Note that the definition of this state is slightly different
+	from the basic model definition: CPU_UP does not mean that the
+	CPU is coherent yet, but it does mean that it is safe to resume
+	the kernel.  The kernel handles the rest of the resume
+	procedure, so the remaining steps are not visible as part of the
+	race avoidance algorithm.
+
+	The CPU remains in this state until an explicit policy decision
+	is made to shut down or suspend the CPU.
+
+	Next state:	CPU_GOING_DOWN
+	Conditions:	none
+	Trigger events:	explicit policy decision
+
+
+CPU_GOING_DOWN:
+
+	While in this state, the CPU exits coherency, including any
+	operations required to achieve this (such as cleaning data
+	caches).
+
+	Next state:	CPU_DOWN
+	Conditions:	local CPU teardown complete
+	Trigger events:	(spontaneous)
+
+
+Cluster state
+-------------
+
+A cluster is a group of connected CPUs with some common resources.
+Because a cluster contains multiple CPUs, it can be doing multiple
+things at the same time.  This has some implications.  In particular, a
+CPU can start up while another CPU is tearing the cluster down.
+
+In this discussion, the "outbound side" is the view of the cluster state
+as seen by a CPU tearing the cluster down.  The "inbound side" is the
+view of the cluster state as seen by a CPU setting the CPU up.
+
+In order to enable safe coordination in such situations, it is important
+that a CPU which is setting up the cluster can advertise its state
+independently of the CPU which is tearing down the cluster.  For this
+reason, the cluster state is split into two parts:
+
+	"cluster" state: The global state of the cluster; or the state
+		on the outbound side:
+
+		CLUSTER_DOWN
+		CLUSTER_UP
+		CLUSTER_GOING_DOWN
+
+	"inbound" state: The state of the cluster on the inbound side.
+
+		INBOUND_NOT_COMING_UP
+		INBOUND_COMING_UP
+
+
+	The different pairings of these states results in six possible
+	states for the cluster as a whole:
+
+	                            CLUSTER_UP
+	          +==========> INBOUND_NOT_COMING_UP -------------+
+	          #                                               |
+	                                                          |
+	     CLUSTER_UP     <----+                                |
+	  INBOUND_COMING_UP      |                                v
+
+	          ^             CLUSTER_GOING_DOWN       CLUSTER_GOING_DOWN
+	          #              INBOUND_COMING_UP <=== INBOUND_NOT_COMING_UP
+
+	    CLUSTER_DOWN         |                                |
+	  INBOUND_COMING_UP <----+                                |
+	                                                          |
+	          ^                                               |
+	          +===========     CLUSTER_DOWN      <------------+
+	                       INBOUND_NOT_COMING_UP
+
+	Transitions -----> can only be made by the outbound CPU, and
+	only involve changes to the "cluster" state.
+
+	Transitions ===##> can only be made by the inbound CPU, and only
+	involve changes to the "inbound" state, except where there is no
+	further transition possible on the outbound side (i.e., the
+	outbound CPU has put the cluster into the CLUSTER_DOWN state).
+
+	The race avoidance algorithm does not provide a way to determine
+	which exact CPUs within the cluster play these roles.  This must
+	be decided in advance by some other means.  Refer to the section
+	"Last man and first man selection" for more explanation.
+
+
+	CLUSTER_DOWN/INBOUND_NOT_COMING_UP is the only state where the
+	cluster can actually be powered down.
+
+	The parallelism of the inbound and outbound CPUs is observed by
+	the existence of two different paths from CLUSTER_GOING_DOWN/
+	INBOUND_NOT_COMING_UP (corresponding to GOING_DOWN in the basic
+	model) to CLUSTER_DOWN/INBOUND_COMING_UP (corresponding to
+	COMING_UP in the basic model).  The second path avoids cluster
+	teardown completely.
+
+	CLUSTER_UP/INBOUND_COMING_UP is equivalent to UP in the basic
+	model.  The final transition to CLUSTER_UP/INBOUND_NOT_COMING_UP
+	is trivial and merely resets the state machine ready for the
+	next cycle.
+
+	Details of the allowable transitions follow.
+
+	The next state in each case is notated
+
+		<cluster state>/<inbound state> (<transitioner>)
+
+	where the <transitioner> is the side on which the transition
+	can occur; either the inbound or the outbound side.
+
+
+CLUSTER_DOWN/INBOUND_NOT_COMING_UP:
+
+	Next state:	CLUSTER_DOWN/INBOUND_COMING_UP (inbound)
+	Conditions:	none
+	Trigger events:
+
+		a) an explicit hardware power-up operation, resulting
+		   from a policy decision on another CPU;
+
+		b) a hardware event, such as an interrupt.
+
+
+CLUSTER_DOWN/INBOUND_COMING_UP:
+
+	In this state, an inbound CPU sets up the cluster, including
+	enabling of hardware coherency at the cluster level and any
+	other operations (such as cache invalidation) which are required
+	in order to achieve this.
+
+	The purpose of this state is to do sufficient cluster-level
+	setup to enable other CPUs in the cluster to enter coherency
+	safely.
+
+	Next state:	CLUSTER_UP/INBOUND_COMING_UP (inbound)
+	Conditions:	cluster-level setup and hardware coherency complete
+	Trigger events:	(spontaneous)
+
+
+CLUSTER_UP/INBOUND_COMING_UP:
+
+	Cluster-level setup is complete and hardware coherency is
+	enabled for the cluster.  Other CPUs in the cluster can safely
+	enter coherency.
+
+	This is a transient state, leading immediately to
+	CLUSTER_UP/INBOUND_NOT_COMING_UP.  All other CPUs on the cluster
+	should consider treat these two states as equivalent.
+
+	Next state:	CLUSTER_UP/INBOUND_NOT_COMING_UP (inbound)
+	Conditions:	none
+	Trigger events:	(spontaneous)
+
+
+CLUSTER_UP/INBOUND_NOT_COMING_UP:
+
+	Cluster-level setup is complete and hardware coherency is
+	enabled for the cluster.  Other CPUs in the cluster can safely
+	enter coherency.
+
+	The cluster will remain in this state until a policy decision is
+	made to power the cluster down.
+
+	Next state:	CLUSTER_GOING_DOWN/INBOUND_NOT_COMING_UP (outbound)
+	Conditions:	none
+	Trigger events:	policy decision to power down the cluster
+
+
+CLUSTER_GOING_DOWN/INBOUND_NOT_COMING_UP:
+
+	An outbound CPU is tearing the cluster down.  The selected CPU
+	must wait in this state until all CPUs in the cluster are in the
+	CPU_DOWN state.
+
+	When all CPUs are in the CPU_DOWN state, the cluster can be torn
+	down, for example by cleaning data caches and exiting
+	cluster-level coherency.
+
+	To avoid wasteful unnecessary teardown operations, the outbound
+	should check the inbound cluster state for asynchronous
+	transitions to INBOUND_COMING_UP.  Alternatively, individual
+	CPUs can be checked for entry into CPU_COMING_UP or CPU_UP.
+
+
+	Next states:
+
+	CLUSTER_DOWN/INBOUND_NOT_COMING_UP (outbound)
+		Conditions:	cluster torn down and ready to power off
+		Trigger events:	(spontaneous)
+
+	CLUSTER_GOING_DOWN/INBOUND_COMING_UP (inbound)
+		Conditions:	none
+		Trigger events:
+
+			a) an explicit hardware power-up operation,
+			   resulting from a policy decision on another
+			   CPU;
+
+			b) a hardware event, such as an interrupt.
+
+
+CLUSTER_GOING_DOWN/INBOUND_COMING_UP:
+
+	The cluster is (or was) being torn down, but another CPU has
+	come online in the meantime and is trying to set up the cluster
+	again.
+
+	If the outbound CPU observes this state, it has two choices:
+
+		a) back out of teardown, restoring the cluster to the
+		   CLUSTER_UP state;
+
+		b) finish tearing the cluster down and put the cluster
+		   in the CLUSTER_DOWN state; the inbound CPU will
+		   set up the cluster again from there.
+
+	Choice (a) permits the removal of some latency by avoiding
+	unnecessary teardown and setup operations in situations where
+	the cluster is not really going to be powered down.
+
+
+	Next states:
+
+	CLUSTER_UP/INBOUND_COMING_UP (outbound)
+		Conditions:	cluster-level setup and hardware
+				coherency complete
+		Trigger events:	(spontaneous)
+
+	CLUSTER_DOWN/INBOUND_COMING_UP (outbound)
+		Conditions:	cluster torn down and ready to power off
+		Trigger events:	(spontaneous)
+
+
+Last man and First man selection
+--------------------------------
+
+The CPU which performs cluster tear-down operations on the outbound side
+is commonly referred to as the "last man".
+
+The CPU which performs cluster setup on the inbound side is commonly
+referred to as the "first man".
+
+The race avoidance algorithm documented above does not provide a
+mechanism to choose which CPUs should play these roles.
+
+
+Last man:
+
+When shutting down the cluster, all the CPUs involved are initially
+executing Linux and hence coherent.  Therefore, ordinary spinlocks can
+be used to select a last man safely, before the CPUs become
+non-coherent.
+
+
+First man:
+
+Because CPUs may power up asynchronously in response to external wake-up
+events, a dynamic mechanism is needed to make sure that only one CPU
+attempts to play the first man role and do the cluster-level
+initialisation: any other CPUs must wait for this to complete before
+proceeding.
+
+Cluster-level initialisation may involve actions such as configuring
+coherency controls in the bus fabric.
+
+The current implementation in mcpm_head.S uses a separate mutual exclusion
+mechanism to do this arbitration.  This mechanism is documented in
+detail in vlocks.txt.
+
+
+Features and Limitations
+------------------------
+
+Implementation:
+
+	The current ARM-based implementation is split between
+	arch/arm/common/mcpm_head.S (low-level inbound CPU operations) and
+	arch/arm/common/mcpm_entry.c (everything else):
+
+	__mcpm_cpu_going_down() signals the transition of a CPU to the
+		CPU_GOING_DOWN state.
+
+	__mcpm_cpu_down() signals the transition of a CPU to the CPU_DOWN
+		state.
+
+	A CPU transitions to CPU_COMING_UP and then to CPU_UP via the
+		low-level power-up code in mcpm_head.S.  This could
+		involve CPU-specific setup code, but in the current
+		implementation it does not.
+
+	__mcpm_outbound_enter_critical() and __mcpm_outbound_leave_critical()
+		handle transitions from CLUSTER_UP to CLUSTER_GOING_DOWN
+		and from there to CLUSTER_DOWN or back to CLUSTER_UP (in
+		the case of an aborted cluster power-down).
+
+		These functions are more complex than the __mcpm_cpu_*()
+		functions due to the extra inter-CPU coordination which
+		is needed for safe transitions at the cluster level.
+
+	A cluster transitions from CLUSTER_DOWN back to CLUSTER_UP via
+		the low-level power-up code in mcpm_head.S.  This
+		typically involves platform-specific setup code,
+		provided by the platform-specific power_up_setup
+		function registered via mcpm_sync_init.
+
+Deep topologies:
+
+	As currently described and implemented, the algorithm does not
+	support CPU topologies involving more than two levels (i.e.,
+	clusters of clusters are not supported).  The algorithm could be
+	extended by replicating the cluster-level states for the
+	additional topological levels, and modifying the transition
+	rules for the intermediate (non-outermost) cluster levels.

+vlocks for Bare-Metal Mutual Exclusion
+======================================
+
+Voting Locks, or "vlocks" provide a simple low-level mutual exclusion
+mechanism, with reasonable but minimal requirements on the memory
+system.
+
+These are intended to be used to coordinate critical activity among CPUs
+which are otherwise non-coherent, in situations where the hardware
+provides no other mechanism to support this and ordinary spinlocks
+cannot be used.
+
+
+vlocks make use of the atomicity provided by the memory system for
+writes to a single memory location.  To arbitrate, every CPU "votes for
+itself", by storing a unique number to a common memory location.  The
+final value seen in that memory location when all the votes have been
+cast identifies the winner.
+
+In order to make sure that the election produces an unambiguous result
+in finite time, a CPU will only enter the election in the first place if
+no winner has been chosen and the election does not appear to have
+started yet.
+
+
+Algorithm
+---------
+
+The easiest way to explain the vlocks algorithm is with some pseudo-code:
+
+
+	int currently_voting[NR_CPUS] = { 0, };
+	int last_vote = -1; /* no votes yet */
+
+	bool vlock_trylock(int this_cpu)
+	{
+		/* signal our desire to vote */
+		currently_voting[this_cpu] = 1;
+		if (last_vote != -1) {
+			/* someone already volunteered himself */
+			currently_voting[this_cpu] = 0;
+			return false; /* not ourself */
+		}
+
+		/* let's suggest ourself */
+		last_vote = this_cpu;
+		currently_voting[this_cpu] = 0;
+
+		/* then wait until everyone else is done voting */
+		for_each_cpu(i) {
+			while (currently_voting[i] != 0)
+				/* wait */;
+		}
+
+		/* result */
+		if (last_vote == this_cpu)
+			return true; /* we won */
+		return false;
+	}
+
+	bool vlock_unlock(void)
+	{
+		last_vote = -1;
+	}
+
+
+The currently_voting[] array provides a way for the CPUs to determine
+whether an election is in progress, and plays a role analogous to the
+"entering" array in Lamport's bakery algorithm [1].
+
+However, once the election has started, the underlying memory system
+atomicity is used to pick the winner.  This avoids the need for a static
+priority rule to act as a tie-breaker, or any counters which could
+overflow.
+
+As long as the last_vote variable is globally visible to all CPUs, it
+will contain only one value that won't change once every CPU has cleared
+its currently_voting flag.
+
+
+Features and limitations
+------------------------
+
+ * vlocks are not intended to be fair.  In the contended case, it is the
+   _last_ CPU which attempts to get the lock which will be most likely
+   to win.
+
+   vlocks are therefore best suited to situations where it is necessary
+   to pick a unique winner, but it does not matter which CPU actually
+   wins.
+
+ * Like other similar mechanisms, vlocks will not scale well to a large
+   number of CPUs.
+
+   vlocks can be cascaded in a voting hierarchy to permit better scaling
+   if necessary, as in the following hypothetical example for 4096 CPUs:
+
+	/* first level: local election */
+	my_town = towns[(this_cpu >> 4) & 0xf];
+	I_won = vlock_trylock(my_town, this_cpu & 0xf);
+	if (I_won) {
+		/* we won the town election, let's go for the state */
+		my_state = states[(this_cpu >> 8) & 0xf];
+		I_won = vlock_lock(my_state, this_cpu & 0xf));
+		if (I_won) {
+			/* and so on */
+			I_won = vlock_lock(the_whole_country, this_cpu & 0xf];
+			if (I_won) {
+				/* ... */
+			}
+			vlock_unlock(the_whole_country);
+		}
+		vlock_unlock(my_state);
+	}
+	vlock_unlock(my_town);
+
+
+ARM implementation
+------------------
+
+The current ARM implementation [2] contains some optimisations beyond
+the basic algorithm:
+
+ * By packing the members of the currently_voting array close together,
+   we can read the whole array in one transaction (providing the number
+   of CPUs potentially contending the lock is small enough).  This
+   reduces the number of round-trips required to external memory.
+
+   In the ARM implementation, this means that we can use a single load
+   and comparison:
+
+	LDR	Rt, [Rn]
+	CMP	Rt, #0
+
+   ...in place of code equivalent to:
+
+	LDRB	Rt, [Rn]
+	CMP	Rt, #0
+	LDRBEQ	Rt, [Rn, #1]
+	CMPEQ	Rt, #0
+	LDRBEQ	Rt, [Rn, #2]
+	CMPEQ	Rt, #0
+	LDRBEQ	Rt, [Rn, #3]
+	CMPEQ	Rt, #0
+
+   This cuts down on the fast-path latency, as well as potentially
+   reducing bus contention in contended cases.
+
+   The optimisation relies on the fact that the ARM memory system
+   guarantees coherency between overlapping memory accesses of
+   different sizes, similarly to many other architectures.  Note that
+   we do not care which element of currently_voting appears in which
+   bits of Rt, so there is no need to worry about endianness in this
+   optimisation.
+
+   If there are too many CPUs to read the currently_voting array in
+   one transaction then multiple transations are still required.  The
+   implementation uses a simple loop of word-sized loads for this
+   case.  The number of transactions is still fewer than would be
+   required if bytes were loaded individually.
+
+
+   In principle, we could aggregate further by using LDRD or LDM, but
+   to keep the code simple this was not attempted in the initial
+   implementation.
+
+
+ * vlocks are currently only used to coordinate between CPUs which are
+   unable to enable their caches yet.  This means that the
+   implementation removes many of the barriers which would be required
+   when executing the algorithm in cached memory.
+
+   packing of the currently_voting array does not work with cached
+   memory unless all CPUs contending the lock are cache-coherent, due
+   to cache writebacks from one CPU clobbering values written by other
+   CPUs.  (Though if all the CPUs are cache-coherent, you should be
+   probably be using proper spinlocks instead anyway).
+
+
+ * The "no votes yet" value used for the last_vote variable is 0 (not
+   -1 as in the pseudocode).  This allows statically-allocated vlocks
+   to be implicitly initialised to an unlocked state simply by putting
+   them in .bss.
+
+   An offset is added to each CPU's ID for the purpose of setting this
+   variable, so that no CPU uses the value 0 for its ID.
