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,
be probed later if another device registers. (Which is OK, since
this interface is only for use with non-hotpluggable devices.)
+
+Early Platform Devices and Drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The early platform interfaces provide platform data to platform device
+drivers early on during the system boot. The code is built on top of the
+early_param() command line parsing and can be executed very early on.
+
+Example: "earlyprintk" class early serial console in 6 steps
+
+1. Registering early platform device data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code registers platform device data using the function
+early_platform_add_devices(). In the case of early serial console this
+should be hardware configuration for the serial port. Devices registered
+at this point will later on be matched against early platform drivers.
+
+2. Parsing kernel command line
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code calls parse_early_param() to parse the kernel
+command line. This will execute all matching early_param() callbacks.
+User specified early platform devices will be registered at this point.
+For the early serial console case the user can specify port on the
+kernel command line as "earlyprintk=serial.0" where "earlyprintk" is
+the class string, "serial" is the name of the platfrom driver and
+0 is the platform device id. If the id is -1 then the dot and the
+id can be omitted.
+
+3. Installing early platform drivers belonging to a certain class
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code may optionally force registration of all early
+platform drivers belonging to a certain class using the function
+early_platform_driver_register_all(). User specified devices from
+step 2 have priority over these. This step is omitted by the serial
+driver example since the early serial driver code should be disabled
+unless the user has specified port on the kernel command line.
+
+4. Early platform driver registration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Compiled-in platform drivers making use of early_platform_init() are
+automatically registered during step 2 or 3. The serial driver example
+should use early_platform_init("earlyprintk", &platform_driver).
+
+5. Probing of early platform drivers belonging to a certain class
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The architecture code calls early_platform_driver_probe() to match
+registered early platform devices associated with a certain class with
+registered early platform drivers. Matched devices will get probed().
+This step can be executed at any point during the early boot. As soon
+as possible may be good for the serial port case.
+
+6. Inside the early platform driver probe()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The driver code needs to take special care during early boot, especially
+when it comes to memory allocation and interrupt registration. The code
+in the probe() function can use is_early_platform_device() to check if
+it is called at early platform device or at the regular platform device
+time. The early serial driver performs register_console() at this point.
+

-/* Since there's no way to auto-probe the I2C devices connected to the I2C
- * bus on the go7007, we have this silly little registration system that
- * client drivers can use to register their I2C driver ID and their
- * detect_client function (the one that's normally passed to i2c_probe).
- *
- * When a new go7007 device is connected, we can look up in a board info
- * table by the USB or PCI vendor/product/revision ID to determine
- * which I2C client module to load. The client driver module will register
- * itself here, and then we can call the registered detect_client function
- * to force-load a new client at the address listed in the board info table.
- *
- * Really the I2C subsystem should have a way to force-load I2C client
- * drivers when we have a priori knowledge of what's on the bus, especially
- * since the existing I2C auto-probe mechanism is so hokey, but we'll use
- * our own mechanism for the time being. */

+ * allocate bio for IO before attempting to allocate a new one. Failure to

*
* Description:
- * This function does little more than loop over the pipe and call
- * @actor to do the actual moving of a single struct pipe_buffer to

+ * This function loops over the pipe and calls @actor to do the
+ * actual moving of a single struct pipe_buffer to the desired
+ * destination. It returns when there's no more buffers left in
+ * the pipe or if the requested number of bytes (@sd->total_len)
+ * have been copied. It returns a positive number (one) if the
+ * pipe needs to be filled with more data, zero if the required
+ * number of bytes have been copied and -errno on error.
*
+ * This, together with splice_from_pipe_{begin,end,next}, may be
+ * used to implement the functionality of __splice_from_pipe() when
+ * locking is required around copying the pipe buffers to the
+ * destination.

+ * 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.
