iii. Plugging the queue to batch requests in anticipation of opportunities for
merge/sort optimizations
This is just the same as in 2.4 so far, though per-device unplugging
support is anticipated for 2.5. Also with a priority-based i/o scheduler,
such decisions could be based on request priorities.
Plugging is an approach that the current i/o scheduling algorithm resorts to so
that it collects up enough requests in the queue to be able to take
advantage of the sorting/merging logic in the elevator. If the
queue is empty when a request comes in, then it plugs the request queue
(sort of like plugging the bottom of a vessel to get fluid to build up)
(sort of like plugging the bath tub of a vessel to get fluid to build up)
till it fills up with a few more requests, before starting to service
the requests. This provides an opportunity to merge/sort the requests before
passing them down to the device. There are various conditions when the queue is
unplugged (to open up the flow again), either through a scheduled task or
could be on demand. For example wait_on_buffer sets the unplugging going
(by running tq_disk) so the read gets satisfied soon. So in the read case,
the queue gets explicitly unplugged as part of waiting for completion,
in fact all queues get unplugged as a side-effect.
through sync_buffer() running blk_run_address_space(mapping). Or the caller
can do it explicity through blk_unplug(bdev). So in the read case,
the queue gets explicitly unplugged as part of waiting for completion on that
buffer. For page driven IO, the address space ->sync_page() takes care of
doing the blk_run_address_space().
Aside:
This is kind of controversial territory, as it's not clear if plugging is

multi-page bios being queued in one shot, we may not need to wait to merge
a big request from the broken up pieces coming by.
Per-queue granularity unplugging (still a Todo) may help reduce some of the
concerns with just a single tq_disk flush approach. Something like
blk_kick_queue() to unplug a specific queue (right away ?)
or optionally, all queues, is in the plan.
4.4 I/O contexts
I/O contexts provide a dynamically allocated per process data area. They may
be used in I/O schedulers, and in the block layer (could be used for IO statis,

What `model` option values are available depends on the codec chip.

Thus, the first thing you can do for any brand-new, unsupported and
non-working HD-audio hardware is to check HD-audio codec and several
different `model` option values. If you have a luck, some of them

might suit with your device well.
Some codecs such as ALC880 have a special model option `model=test`.

* at least @nr_iovecs entries. Allocations will be done from the
* fs_bio_set. Also see @bio_alloc_bioset.
*
* If %__GFP_WAIT is set, then bio_alloc will always be able to allocate
* a bio. This is due to the mempool guarantees. To make this work, callers
* must never allocate more than 1 bio at the time from this pool. Callers
* that need to allocate more than 1 bio must always submit the previously
* allocate bio for IO before attempting to allocate a new one. Failure to
* do so can cause livelocks under memory pressure.

/*
* The below are the various read and write types that we support. Some of
* them include behavioral modifiers that send information down to the
* block layer and IO scheduler. Terminology:
*
* The block layer uses device plugging to defer IO a little bit, in
* the hope that we will see more IO very shortly. This increases
* coalescing of adjacent IO and thus reduces the number of IOs we
* have to send to the device. It also allows for better queuing,
* if the IO isn't mergeable. If the caller is going to be waiting
* for the IO, then he must ensure that the device is unplugged so
* that the IO is dispatched to the driver.
*
* All IO is handled async in Linux. This is fine for background
* writes, but for reads or writes that someone waits for completion
* on, we want to notify the block layer and IO scheduler so that they
* know about it. That allows them to make better scheduling
* decisions. So when the below references 'sync' and 'async', it
* is referencing this priority hint.
*
* With that in mind, the available types are:
*
* READ A normal read operation. Device will be plugged.
* READ_SYNC A synchronous read. Device is not plugged, caller can
* immediately wait on this read without caring about
* unplugging.
* READA Used for read-ahead operations. Lower priority, and the
* block layer could (in theory) choose to ignore this
* request if it runs into resource problems.
* WRITE A normal async write. Device will be plugged.
* SWRITE Like WRITE, but a special case for ll_rw_block() that
* tells it to lock the buffer first. Normally a buffer
* must be locked before doing IO.
* WRITE_SYNC_PLUG Synchronous write. Identical to WRITE, but passes down
* the hint that someone will be waiting on this IO
* shortly. The device must still be unplugged explicitly,
* WRITE_SYNC_PLUG does not do this as we could be
* submitting more writes before we actually wait on any
* of them.
* WRITE_SYNC Like WRITE_SYNC_PLUG, but also unplugs the device
* immediately after submission. The write equivalent
* of READ_SYNC.
* WRITE_ODIRECT Special case write for O_DIRECT only.
* SWRITE_SYNC
* SWRITE_SYNC_PLUG Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks the buffer.
* See SWRITE.
* WRITE_BARRIER Like WRITE, but tells the block layer that all
* previously submitted writes must be safely on storage
* before this one is started. Also guarantees that when
* this write is complete, it itself is also safely on
* storage. Prevents reordering of writes on both sides
* of this IO.
