+
+With the move to private task_work, SQPOLL neglected to also run the
+normal task_work, if any is pending. This will eventually get run, but
+we should run it with the private task_work to ensure that things like
+a final fput() is processed in a timely fashion.

+V2: move the task_work_run() section so we're always guaranteed it
+ runs after any task_work. Ran the previous test cases again, both
+ the yarn based one and the liburing test case, and they still work
+ as they should. Previously, if we had a retry condition due to being
+ flooded with task_work, then we'd not run the kernel side task_work.

-With the move to private task_work, SQPOLL neglected to also run the
-normal task_work, if any is pending. This will eventually get run, but
-we should run it with the private task_work to ensure that things like
-a final fput() is processed in a timely fashion.

-V2: move the task_work_run() section so we're always guaranteed it
- runs after any task_work. Ran the previous test cases again, both
- the yarn based one and the liburing test case, and they still work
- as they should. Previously, if we had a retry condition due to being
- flooded with task_work, then we'd not run the kernel side task_work.

++ * section in __usb_hcd_giveback_urb() in this case.
++ *
++ * 2. Disables interrupts for the duration of the coverage collection section.
++ * This allows avoiding nested remote coverage collection sections in the
++ * softirq context (a softirq might occur during the execution of a work in
++ * the BH workqueue, which runs with in_serving_softirq() > 0).
++ * For example, usb_giveback_urb_bh() runs in the BH workqueue with
++ * interrupts enabled, so __usb_hcd_giveback_urb() might be interrupted in
++ * the middle of its remote coverage collection section, and the interrupt
++ * handler might invoke __usb_hcd_giveback_urb() again.

++ BitMap queue CPU Scheduler
++ --------------------------
++
++CONTENT
++========
++
++ Background
++ Design
++ Overview
++ Task policy
++ Priority management
++ BitMap Queue
++ CPU Assignment and Migration
++
++
++Background
++==========
++
++BitMap Queue CPU scheduler, referred to as BMQ from here on, is an evolution
++of previous Priority and Deadline based Skiplist multiple queue scheduler(PDS),
++and inspired by Zircon scheduler. The goal of it is to keep the scheduler code
++simple, while efficiency and scalable for interactive tasks, such as desktop,
++movie playback and gaming etc.
++
++Design
++======
++
++Overview
++--------
++
++BMQ use per CPU run queue design, each CPU(logical) has it's own run queue,
++each CPU is responsible for scheduling the tasks that are putting into it's
++run queue.
++
++The run queue is a set of priority queues. Note that these queues are fifo
++queue for non-rt tasks or priority queue for rt tasks in data structure. See
++BitMap Queue below for details. BMQ is optimized for non-rt tasks in the fact
++that most applications are non-rt tasks. No matter the queue is fifo or
++priority, In each queue is an ordered list of runnable tasks awaiting execution
++and the data structures are the same. When it is time for a new task to run,
++the scheduler simply looks the lowest numbered queueue that contains a task,
++and runs the first task from the head of that queue. And per CPU idle task is
++also in the run queue, so the scheduler can always find a task to run on from
++its run queue.
++
++Each task will assigned the same timeslice(default 4ms) when it is picked to
++start running. Task will be reinserted at the end of the appropriate priority
++queue when it uses its whole timeslice. When the scheduler selects a new task
++from the priority queue it sets the CPU's preemption timer for the remainder of
++the previous timeslice. When that timer fires the scheduler will stop execution
++on that task, select another task and start over again.
++
++If a task blocks waiting for a shared resource then it's taken out of its
++priority queue and is placed in a wait queue for the shared resource. When it
++is unblocked it will be reinserted in the appropriate priority queue of an
++eligible CPU.
++
++Task policy
++-----------
++
++BMQ supports DEADLINE, FIFO, RR, NORMAL, BATCH and IDLE task policy like the
++mainline CFS scheduler. But BMQ is heavy optimized for non-rt task, that's
++NORMAL/BATCH/IDLE policy tasks. Below is the implementation detail of each
++policy.
++
++DEADLINE
++ It is squashed as priority 0 FIFO task.
++
++FIFO/RR
++ All RT tasks share one single priority queue in BMQ run queue designed. The
++complexity of insert operation is O(n). BMQ is not designed for system runs
++with major rt policy tasks.
++
++NORMAL/BATCH/IDLE
++ BATCH and IDLE tasks are treated as the same policy. They compete CPU with
++NORMAL policy tasks, but they just don't boost. To control the priority of
++NORMAL/BATCH/IDLE tasks, simply use nice level.
++
++ISO
++ ISO policy is not supported in BMQ. Please use nice level -20 NORMAL policy
++task instead.
++
++Priority management
++-------------------
++
++RT tasks have priority from 0-99. For non-rt tasks, there are three different
++factors used to determine the effective priority of a task. The effective
++priority being what is used to determine which queue it will be in.
++
++The first factor is simply the task’s static priority. Which is assigned from
++task's nice level, within [-20, 19] in userland's point of view and [0, 39]
++internally.
++
++The second factor is the priority boost. This is a value bounded between
++[-MAX_PRIORITY_ADJ, MAX_PRIORITY_ADJ] used to offset the base priority, it is
++modified by the following cases:
++
++*When a thread has used up its entire timeslice, always deboost its boost by
++increasing by one.
++*When a thread gives up cpu control(voluntary or non-voluntary) to reschedule,
++and its switch-in time(time after last switch and run) below the thredhold
++based on its priority boost, will boost its boost by decreasing by one buti is
++capped at 0 (won’t go negative).
++
++The intent in this system is to ensure that interactive threads are serviced
++quickly. These are usually the threads that interact directly with the user
++and cause user-perceivable latency. These threads usually do little work and
++spend most of their time blocked awaiting another user event. So they get the
++priority boost from unblocking while background threads that do most of the
++processing receive the priority penalty for using their entire timeslice.

++ * hrtimer_cpu_base->lock (hrtimer_start() for bandwidth controls)
++ *
++ * rq1->lock
++ * rq2->lock where: rq1 < rq2
++ *
++ * Regular state:
++ *
++ * Normal scheduling state is serialized by rq->lock. __schedule() takes the
++ * local CPU's rq->lock, it optionally removes the task from the runqueue and
++ * always looks at the local rq data structures to find the most eligible task
++ * to run next.
++ *
++ * Task enqueue is also under rq->lock, possibly taken from another CPU.
++ * Wakeups from another LLC domain might use an IPI to transfer the enqueue to
++ * the local CPU to avoid bouncing the runqueue state around [ see
++ * ttwu_queue_wakelist() ]
++ *
++ * Task wakeup, specifically wakeups that involve migration, are horribly
++ * complicated to avoid having to take two rq->locks.
++ *
++ * Special state:
++ *
++ * System-calls and anything external will use task_rq_lock() which acquires
++ * both p->pi_lock and rq->lock. As a consequence the state they change is
++ * stable while holding either lock:
++ *
++ * - sched_setaffinity()/
++ * set_cpus_allowed_ptr(): p->cpus_ptr, p->nr_cpus_allowed
++ * - set_user_nice(): p->se.load, p->*prio
++ * - __sched_setscheduler(): p->sched_class, p->policy, p->*prio,
++ * p->se.load, p->rt_priority,
++ * p->dl.dl_{runtime, deadline, period, flags, bw, density}
++ * - sched_setnuma(): p->numa_preferred_nid
++ * - sched_move_task(): p->sched_task_group
++ * - uclamp_update_active() p->uclamp*
++ *
++ * p->state <- TASK_*:
++ *
++ * is changed locklessly using set_current_state(), __set_current_state() or
++ * set_special_state(), see their respective comments, or by
++ * try_to_wake_up(). This latter uses p->pi_lock to serialize against
++ * concurrent self.
++ *
++ * p->on_rq <- { 0, 1 = TASK_ON_RQ_QUEUED, 2 = TASK_ON_RQ_MIGRATING }:
++ *
++ * is set by activate_task() and cleared by deactivate_task(), under
++ * rq->lock. Non-zero indicates the task is runnable, the special
++ * ON_RQ_MIGRATING state is used for migration without holding both
++ * rq->locks. It indicates task_cpu() is not stable, see task_rq_lock().
++ *
++ * p->on_cpu <- { 0, 1 }:
++ *
++ * is set by prepare_task() and cleared by finish_task() such that it will be
++ * set before p is scheduled-in and cleared after p is scheduled-out, both
++ * under rq->lock. Non-zero indicates the task is running on its CPU.
++ *
++ * [ The astute reader will observe that it is possible for two tasks on one
++ * CPU to have ->on_cpu = 1 at the same time. ]
++ *
++ * task_cpu(p): is changed by set_task_cpu(), the rules are:
++ *
++ * - Don't call set_task_cpu() on a blocked task:
++ *
++ * We don't care what CPU we're not running on, this simplifies hotplug,
++ * the CPU assignment of blocked tasks isn't required to be valid.
++ *
++ * - for try_to_wake_up(), called under p->pi_lock:
++ *
++ * This allows try_to_wake_up() to only take one rq->lock, see its comment.
++ *
++ * - for migration called under rq->lock:
++ * [ see task_on_rq_migrating() in task_rq_lock() ]
++ *
++ * o move_queued_task()
++ * o detach_task()
++ *
++ * - for migration called under double_rq_lock():
++ *
++ * o __migrate_swap_task()
++ * o push_rt_task() / pull_rt_task()

++ * Notes on Program-Order guarantees on SMP systems.
++ *
++ * MIGRATION
++ *
++ * The basic program-order guarantee on SMP systems is that when a task [t]
++ * migrates, all its activity on its old CPU [c0] happens-before any subsequent
++ * execution on its new CPU [c1].
++ *
++ * For migration (of runnable tasks) this is provided by the following means:
++ *
++ * A) UNLOCK of the rq(c0)->lock scheduling out task t
++ * B) migration for t is required to synchronize *both* rq(c0)->lock and
++ * rq(c1)->lock (if not at the same time, then in that order).
++ * C) LOCK of the rq(c1)->lock scheduling in task
++ *
++ * Transitivity guarantees that B happens after A and C after B.
++ * Note: we only require RCpc transitivity.
++ * Note: the CPU doing B need not be c0 or c1
++ *
++ * Example:
++ *
++ * CPU0 CPU1 CPU2
++ *
++ * LOCK rq(0)->lock
++ * sched-out X
++ * sched-in Y
++ * UNLOCK rq(0)->lock
++ *
++ * LOCK rq(0)->lock // orders against CPU0
++ * dequeue X
++ * UNLOCK rq(0)->lock
++ *
++ * LOCK rq(1)->lock
++ * enqueue X
++ * UNLOCK rq(1)->lock
++ *
++ * LOCK rq(1)->lock // orders against CPU2
++ * sched-out Z
++ * sched-in X
++ * UNLOCK rq(1)->lock
++ *
++ *
++ * BLOCKING -- aka. SLEEP + WAKEUP
++ *
++ * For blocking we (obviously) need to provide the same guarantee as for
++ * migration. However the means are completely different as there is no lock
++ * chain to provide order. Instead we do:
++ *
++ * 1) smp_store_release(X->on_cpu, 0) -- finish_task()
++ * 2) smp_cond_load_acquire(!X->on_cpu) -- try_to_wake_up()
++ *
++ * Example:
++ *
++ * CPU0 (schedule) CPU1 (try_to_wake_up) CPU2 (schedule)
++ *
++ * LOCK rq(0)->lock LOCK X->pi_lock
++ * dequeue X
++ * sched-out X
++ * smp_store_release(X->on_cpu, 0);
++ *
++ * smp_cond_load_acquire(&X->on_cpu, !VAL);
++ * X->state = WAKING
++ * set_task_cpu(X,2)
++ *
++ * LOCK rq(2)->lock
++ * enqueue X
++ * X->state = RUNNING
++ * UNLOCK rq(2)->lock
++ *
++ * LOCK rq(2)->lock // orders against CPU1
++ * sched-out Z
++ * sched-in X
++ * UNLOCK rq(2)->lock
++ *
++ * UNLOCK X->pi_lock
++ * UNLOCK rq(0)->lock
++ *
++ *
++ * However; for wakeups there is a second guarantee we must provide, namely we
++ * must observe the state that lead to our wakeup. That is, not only must our
++ * task observe its own prior state, it must also observe the stores prior to
++ * its wakeup.
++ *
++ * This means that any means of doing remote wakeups must order the CPU doing
++ * the wakeup against the CPU the task is going to end up running on. This,
++ * however, is already required for the regular Program-Order guarantee above,
++ * since the waking CPU is the one issueing the ACQUIRE (smp_cond_load_acquire).

++ * mm_cid remote-clear implements a lock-free algorithm to clear per-mm/cpu cid

++ * switch.
++ *
++ * There is one basic properties we want to guarantee here:
++ *
++ * (1) Remote-clear should _never_ mark a per-cpu cid UNSET when it is actively
++ * used by a task. That would lead to concurrent allocation of the cid and
++ * userspace corruption.
++ *
++ * Provide this guarantee by introducing a Dekker memory ordering to guarantee
++ * that a pair of loads observe at least one of a pair of stores, which can be
++ * shown as:
++ *
++ * X = Y = 0
++ *
++ * w[X]=1 w[Y]=1
++ * MB MB
++ * r[Y]=y r[X]=x
++ *
++ * Which guarantees that x==0 && y==0 is impossible. But rather than using
++ * values 0 and 1, this algorithm cares about specific state transitions of the
++ * runqueue current task (as updated by the scheduler context switch), and the
++ * per-mm/cpu cid value.
++ *
++ * Let's introduce task (Y) which has task->mm == mm and task (N) which has
++ * task->mm != mm for the rest of the discussion. There are two scheduler state
++ * transitions on context switch we care about:
++ *
++ * (TSA) Store to rq->curr with transition from (N) to (Y)
++ *
++ * (TSB) Store to rq->curr with transition from (Y) to (N)
++ *
++ * On the remote-clear side, there is one transition we care about:
++ *
++ * (TMA) cmpxchg to *pcpu_cid to set the LAZY flag
++ *
++ * There is also a transition to UNSET state which can be performed from all
++ * sides (scheduler, remote-clear). It is always performed with a cmpxchg which
++ * guarantees that only a single thread will succeed:
++ *
++ * (TMB) cmpxchg to *pcpu_cid to mark UNSET
++ *
++ * Just to be clear, what we do _not_ want to happen is a transition to UNSET
++ * when a thread is actively using the cid (property (1)).
++ *
++ * Let's looks at the relevant combinations of TSA/TSB, and TMA transitions.
++ *
++ * Scenario A) (TSA)+(TMA) (from next task perspective)
++ *
++ * CPU0 CPU1
++ *
++ * Context switch CS-1 Remote-clear
++ * - store to rq->curr: (N)->(Y) (TSA) - cmpxchg to *pcpu_id to LAZY (TMA)
++ * (implied barrier after cmpxchg)
++ * - switch_mm_cid()
++ * - memory barrier (see switch_mm_cid()
++ * comment explaining how this barrier
++ * is combined with other scheduler
++ * barriers)
++ * - mm_cid_get (next)
++ * - READ_ONCE(*pcpu_cid) - rcu_dereference(src_rq->curr)
++ *
++ * This Dekker ensures that either task (Y) is observed by the
++ * rcu_dereference() or the LAZY flag is observed by READ_ONCE(), or both are
++ * observed.
++ *
++ * If task (Y) store is observed by rcu_dereference(), it means that there is
++ * still an active task on the cpu. Remote-clear will therefore not transition
++ * to UNSET, which fulfills property (1).
++ *
++ * If task (Y) is not observed, but the lazy flag is observed by READ_ONCE(),
++ * it will move its state to UNSET, which clears the percpu cid perhaps
++ * uselessly (which is not an issue for correctness). Because task (Y) is not
++ * observed, CPU1 can move ahead to set the state to UNSET. Because moving
++ * state to UNSET is done with a cmpxchg expecting that the old state has the
++ * LAZY flag set, only one thread will successfully UNSET.
++ *
++ * If both states (LAZY flag and task (Y)) are observed, the thread on CPU0
++ * will observe the LAZY flag and transition to UNSET (perhaps uselessly), and
++ * CPU1 will observe task (Y) and do nothing more, which is fine.
++ *
++ * What we are effectively preventing with this Dekker is a scenario where
++ * neither LAZY flag nor store (Y) are observed, which would fail property (1)
++ * because this would UNSET a cid which is actively used.

+- * Lock ordering:

+- * The memory_lock semaphore is used by both code paths calling

+- * to protect the memory enable state of the device.
+- *
+- * When zapping vmas we need to maintain the mmap_lock => vma_lock
+- * ordering, which requires using vma_lock to walk vma_list to
+- * acquire an mm, then dropping vma_lock to get the mmap_lock and
+- * reacquiring vma_lock. This logic is derived from similar
+- * requirements in uverbs_user_mmap_disassociate().
+- *
+- * mmap_lock must always be the top-level lock when it is taken.
+- * Therefore we can only hold the memory_lock write lock when
+- * vma_list is empty, as we'd need to take mmap_lock to clear
+- * entries. vma_list can only be guaranteed empty when holding
+- * vma_lock, thus memory_lock is nested under vma_lock.
+- *
+- * This enables the vm_ops.fault callback to acquire vma_lock,
+- * followed by memory_lock read lock, while already holding
+- * mmap_lock without risk of deadlock.
