CFQ (Complete Fairness Queueing)
|
||||
===============================
|
||||
|
||||
The main aim of CFQ scheduler is to provide a fair allocation of the disk
|
||||
I/O bandwidth for all the processes which requests an I/O operation.
|
||||
|
||||
CFQ maintains the per process queue for the processes which request I/O
|
||||
operation(syncronous requests). In case of asynchronous requests, all the
|
||||
requests from all the processes are batched together according to their
|
||||
process's I/O priority.

||||

||||
controller or for storage arrays), setting slice_idle=0 might end up in better
|
||||
throughput and acceptable latencies.
|
||||
|
||||
back_seek_max
|
||||
-------------
|
||||
This specifies, given in Kbytes, the maximum "distance" for backward seeking.
|
||||
The distance is the amount of space from the current head location to the
|
||||
sectors that are backward in terms of distance.
|
||||
|
||||
This parameter allows the scheduler to anticipate requests in the "backward"
|
||||
direction and consider them as being the "next" if they are within this
|
||||
distance from the current head location.
|
||||
|
||||
back_seek_penalty
|
||||
-----------------
|
||||
This parameter is used to compute the cost of backward seeking. If the
|
||||
backward distance of request is just 1/back_seek_penalty from a "front"
|
||||
request, then the seeking cost of two requests is considered equivalent.
|
||||
|
||||
So scheduler will not bias toward one or the other request (otherwise scheduler
|
||||
will bias toward front request). Default value of back_seek_penalty is 2.
|
||||
|
||||
fifo_expire_async
|
||||
-----------------
|
||||
This parameter is used to set the timeout of asynchronous requests. Default
|
||||
value of this is 248ms.
|
||||
|
||||
fifo_expire_sync
|
||||
----------------
|
||||
This parameter is used to set the timeout of synchronous requests. Default
|
||||
value of this is 124ms. In case to favor synchronous requests over asynchronous
|
||||
one, this value should be decreased relative to fifo_expire_async.
|
||||
|
||||
slice_async
|
||||
-----------
|
||||
This parameter is same as of slice_sync but for asynchronous queue. The
|
||||
default value is 40ms.
|
||||
|
||||
slice_async_rq
|
||||
--------------
|
||||
This parameter is used to limit the dispatching of asynchronous request to
|
||||
device request queue in queue's slice time. The maximum number of request that
|
||||
are allowed to be dispatched also depends upon the io priority. Default value
|
||||
for this is 2.
|
||||
|
||||
slice_sync
|
||||
----------
|
||||
When a queue is selected for execution, the queues IO requests are only
|
||||
executed for a certain amount of time(time_slice) before switching to another
|
||||
queue. This parameter is used to calculate the time slice of synchronous
|
||||
queue.
|
||||
|
||||
time_slice is computed using the below equation:-
|
||||
time_slice = slice_sync + (slice_sync/5 * (4 - prio)). To increase the
|
||||
time_slice of synchronous queue, increase the value of slice_sync. Default
|
||||
value is 100ms.
|
||||
|
||||
quantum
|
||||
-------
|
||||
This specifies the number of request dispatched to the device queue. In a
|
||||
queue's time slice, a request will not be dispatched if the number of request
|
||||
in the device exceeds this parameter. This parameter is used for synchronous
|
||||
request.
|
||||
|
||||
In case of storage with several disk, this setting can limit the parallel
|
||||
processing of request. Therefore, increasing the value can imporve the
|
||||
performace although this can cause the latency of some I/O to increase due
|
||||
to more number of requests.

* ARM Versatile FPGA interrupt controller
|
||||
|
||||
One or more FPGA IRQ controllers can be synthesized in an ARM reference board
|
||||
such as the Integrator or Versatile family. The output of these different
|
||||
controllers are OR:ed together and fed to the CPU tile's IRQ input. Each
|
||||
instance can handle up to 32 interrupts.
|
||||
|
||||
Required properties:
|
||||
- compatible: "arm,versatile-fpga-irq"
|
||||
- interrupt-controller: Identifies the node as an interrupt controller
|
||||
- #interrupt-cells: The number of cells to define the interrupts. Must be 1
|
||||
as the FPGA IRQ controller has no configuration options for interrupt
|
||||
sources. The cell is a u32 and defines the interrupt number.
|
||||
- reg: The register bank for the FPGA interrupt controller.
|
||||
- clear-mask: a u32 number representing the mask written to clear all IRQs
|
||||
on the controller at boot for example.
|
||||
- valid-mask: a u32 number representing a bit mask determining which of
|
||||
the interrupts are valid. Unconnected/unused lines are set to 0, and

the system till not make it possible for devices to request these
|
||||
interrupts.

* arch/alpha/lib/ev6-strncpy_from_user.S
|
||||
* 21264 version contributed by Rick Gorton <rick.gorton@alpha-processor.com>
|
||||
*
|
||||
* Just like strncpy except in the return value:
|
||||
*
|
||||
* -EFAULT if an exception occurs before the terminator is copied.
|
||||
* N if the buffer filled.
|
||||
*
|
||||
* Otherwise the length of the string is returned.
|
||||
*
|
||||
* Much of the information about 21264 scheduling/coding comes from:
|
||||
* Compiler Writer's Guide for the Alpha 21264
|
||||
* abbreviated as 'CWG' in other comments here
|
||||
* ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
|
||||
* Scheduling notation:
|
||||
* E - either cluster
|
||||
* U - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
|
||||
* L - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
|
||||
* A bunch of instructions got moved and temp registers were changed
|
||||
* to aid in scheduling. Control flow was also re-arranged to eliminate
|
||||
* branches, and to provide longer code sequences to enable better scheduling.
|
||||
* A total rewrite (using byte load/stores for start & tail sequences)
|
||||
* is desirable, but very difficult to do without a from-scratch rewrite.
|
||||
* Save that for the future.

|

|

|
||||
* makes sense to support old assembler versions when building that
|
||||
* particular kernel feature.
|
||||
*
|

* The macros defined here should only be used where there is no viable
|
||||
* alternative.
|
||||
*
|
||||
*
|
||||
* __inst_arm(x): emit the specified ARM opcode
|
||||
* __inst_thumb16(x): emit the specified 16-bit Thumb opcode
|
||||
* __inst_thumb32(x): emit the specified 32-bit Thumb opcode
|
||||
*
|
||||
* __inst_arm_thumb16(arm, thumb): emit either the specified arm or
|
||||
* 16-bit Thumb opcode, depending on whether an ARM or Thumb-2
|
||||
* kernel is being built
|
||||
*
|
||||
* __inst_arm_thumb32(arm, thumb): emit either the specified arm or
|
||||
* 32-bit Thumb opcode, depending on whether an ARM or Thumb-2
|
||||
* kernel is being built
|
||||
*
|
||||
*
|
||||
* Note that using these macros directly is poor practice. Instead, you
|
||||
* should use them to define human-readable wrapper macros to encode the
|
||||
* instructions that you care about. In code which might run on ARMv7 or
|
||||
* above, you can usually use the __inst_arm_thumb{16,32} macros to
|

* specify the ARM and Thumb alternatives at the same time. This ensures
|
||||
* that the correct opcode gets emitted depending on the instruction set
|
||||
* used for the kernel build.
|
||||
*
|
||||
* Look at opcodes-virt.h for an example of how to use these macros.
