8 years agostaging: unisys: visorbus: use kernel timer instead of workqueue
Tim Sell [Sat, 11 Jun 2016 01:48:08 +0000 (21:48 -0400)]
staging: unisys: visorbus: use kernel timer instead of workqueue

A kernel timer is now used as the vehicle to periodically call the
channel_interrupt function of registered visor drivers, instead of a
workqueue.

This simplifies a lot of things by making periodic_work.c and
periodic_work.h no longer necessary.  This change also means that the
channel_interrupt() callbacks registered by visor drivers (via
visorbus_register_visor_driver()) will now be called in atomic context
(i.e., canNOT sleep) rather than kernel thread context (CAN sleep).
Fortunately this did NOT necessitate any change to the existing
channel_interrupt() callbacks, because none of them ever perform any
operations that would be invalid in atomic context.

staging: unisys: visorinput: remove unnecessary locking

Locking in the _interrupt() function is NOT necessary so long as we ensure
that interrupts have been stopped whenever we need to pause or resume the
device, which we now do.

While a device is paused, we ensure that interrupts stay disabled, i.e.
that the _interrupt() function will NOT be called, yet remember the desired
state in devdata->interrupts_enabled if open() or close() are called are
called while the device is paused.  Then when the device is resumed, we
restore the actual state of interrupts (i.e., whether _interrupt() is going
to be called or not) to the desired state in devdata->interrupts_enabled.

8 years agoandroid: binder: Remove deprecated create_singlethread_workqueue

android: binder: Remove deprecated create_singlethread_workqueue

The workqueue is being used to run deferred work for the android binder.

The "binder_deferred_workqueue" queues only a single work item and hence
does not require ordering. Also, this workqueue is not being used on a
memory recliam path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

   - Fix the x86 identity mapping creation helpers to avoid the
     assumption that the base address of the mapping will always be
     aligned at the PGD level, as it may be aligned at the PUD level if
     address space randomization is enabled (Rafael Wysocki).

   - Fix the hibernation core to avoid executing tracing functions
     before restoring the processor state completely during resume
     (Thomas Garnier).

   - Fix a recently introduced regression in the powernv cpufreq driver
