uses their own name as the sound card name (short name), and leave the

driver has already explicitly set the long name, this API will do nothing.

This patch also allows for further differentiation as many devices that

7 years agomm: add PageWaiters indicating tasks are waiting for a page bit
Nicholas Piggin [Sun, 25 Dec 2016 03:00:30 +0000 (13:00 +1000)]
mm: add PageWaiters indicating tasks are waiting for a page bit

Add a new page flag, PageWaiters, to indicate the page waitqueue has
tasks waiting. This can be tested rather than testing waitqueue_active
which requires another cacheline load.

This bit is always set when the page has tasks on page_waitqueue(page),
and is set and cleared under the waitqueue lock. It may be set when
there are no tasks on the waitqueue, which will cause a harmless extra
wakeup check that will clears the bit.

The generic bit-waitqueue infrastructure is no longer used for pages.
Instead, waitqueues are used directly with a custom key type. The
generic code was not flexible enough to have PageWaiters manipulation
under the waitqueue lock (which simplifies concurrency).

This improves the performance of page lock intensive microbenchmarks by
2-3%.

Putting two bits in the same word opens the opportunity to remove the
memory barrier between clearing the lock bit and testing the waiters
bit, after some work on the arch primitives (e.g., ensuring memory
operand widths match and cover both bits).

ARM/imx/mmcd: Fix broken cpu hotplug handling

The cpu hotplug support of this perf driver is broken in several ways:

1) It adds a instance before setting up the state.

2) The state for the instance is different from the state of the
   callback. It's just a randomly chosen state.

3) The instance registration is not error checked so nobody noticed that
   the call can never succeed.

4) The state for the multi install callbacks is chosen randomly and
   overwrites existing state. This is now prevented by the core code so the
   call is guaranteed to fail.

5) The error exit path in the init function leaves the instance registered
   and then frees the memory which contains the enqueued hlist node.

6) The remove function is removing the state and not the instance.

Fix it by:

- Setting up the state before adding instances. Use a dynamically allocated
  state for it.

- Installing instances after the state has been set up

- Removing the instance in the error path before freeing memory

- Removing the instance not the state in the driver remove callback

While at is use raw_cpu_processor_id(), because cpu_processor_id() cannot
be used in preemptible context, and set the driver data after successful
registration of the pmu.

tools/power turbostat: remove obsolete -M, -m, -C, -c options

The new --add option has replaced the -M, -m, -C, -c options
Eg.

-M 0x10 is now --add msr0x10,raw
-m 0x10 is now --add msr0x10,raw,u32
-C 0x10 is now --add msr0x10,delta
-c 0x10 is now --add msr0x10,delta,u32

The --add option can be repeated to add any number of counters,
while the previous options were limited to adding one of each type.

In addition, the --add option can accept a column label,
and can also display a counter as a percentage of elapsed cycles.

Eg. --add msr0x3fe,core,percent,MY_CC3
