+<title>Using uio_pdrv for platform devices</title>
+        <para>
+        In many cases, UIO drivers for platform devices can be handled in a
+        generic way. In the same place where you define your
+        <varname>struct platform_device</varname>, you simply also implement
+        your interrupt handler and fill your
+        <varname>struct uio_info</varname>. A pointer to this
+        <varname>struct uio_info</varname> is then used as
+        <varname>platform_data</varname> for your platform device.
+        </para>
+        <para>
+        You also need to set up an array of <varname>struct resource</varname>
+        containing addresses and sizes of your memory mappings. This
+        information is passed to the driver using the
+        <varname>.resource</varname> and <varname>.num_resources</varname>
+        elements of <varname>struct platform_device</varname>.
+        </para>
+        <para>
+        You now have to set the <varname>.name</varname> element of
+        <varname>struct platform_device</varname> to
+        <varname>"uio_pdrv"</varname> to use the generic UIO platform device
+        driver. This driver will fill the <varname>mem[]</varname> array
+        according to the resources given, and register the device.
+        </para>
+        <para>

+        <para>
+        Especially in embedded devices, you frequently find chips where the
+        irq pin is tied to its own dedicated interrupt line. In such cases,
+        where you can be really sure the interrupt is not shared, we can take
+        the concept of <varname>uio_pdrv</varname> one step further and use a

+        The setup for this driver is the same as described above for

+        <varname>struct uio_info</varname> must remain
+        <varname>NULL</varname>. The  <varname>.irq_flags</varname> element

+        The generic interrupt handler of <varname>uio_pdrv_genirq</varname>
+        will simply disable the interrupt line using

+        userspace can reenable the interrupt by writing 0x00000001 to the UIO
+        device file. The driver already implements an
+        <function>irq_control()</function> to make this possible, you must not
+        implement your own.

+        <para>
+        Using <varname>uio_pdrv_genirq</varname> not only saves a few lines of
+        interrupt handler code. You also do not need to know anything about
+        the chip's internal registers to create the kernel part of the driver.
+        All you need to know is the irq number of the pin the chip is

+Queue sysfs files
+=================
+
+This text file will detail the queue files that are located in the sysfs tree
+for each block device. Note that stacked devices typically do not export
+any settings, since their queue merely functions are a remapping target.
+These files are the ones found in the /sys/block/xxx/queue/ directory.
+
+Files denoted with a RO postfix are readonly and the RW postfix means
+read-write.
+
+hw_sector_size (RO)
+-------------------
+This is the hardware sector size of the device, in bytes.
+
+max_hw_sectors_kb (RO)
+----------------------
+This is the maximum number of kilobytes supported in a single data transfer.
+
+max_sectors_kb (RW)
+-------------------
+This is the maximum number of kilobytes that the block layer will allow
+for a filesystem request. Must be smaller than or equal to the maximum
+size allowed by the hardware.
+
+nomerges (RW)
+-------------
+This enables the user to disable the lookup logic involved with IO merging
+requests in the block layer. Merging may still occur through a direct
+1-hit cache, since that comes for (almost) free. The IO scheduler will not
+waste cycles doing tree/hash lookups for merges if nomerges is 1. Defaults
+to 0, enabling all merges.
+
+nr_requests (RW)
+----------------
+This controls how many requests may be allocated in the block layer for
+read or write requests. Note that the total allocated number may be twice
+this amount, since it applies only to reads or writes (not the accumulated
+sum).
+
+read_ahead_kb (RW)
+------------------
+Maximum number of kilobytes to read-ahead for filesystems on this block
+device.
+
+rq_affinity (RW)
+----------------
+If this option is enabled, the block layer will migrate request completions
+to the CPU that originally submitted the request. For some workloads
+this provides a significant reduction in CPU cycles due to caching effects.
+
+scheduler (RW)
+--------------
+When read, this file will display the current and available IO schedulers
+for this block device. The currently active IO scheduler will be enclosed
+in [] brackets. Writing an IO scheduler name to this file will switch
+control of this block device to that new IO scheduler. Note that writing
+an IO scheduler name to this file will attempt to load that IO scheduler
+module, if it isn't already present in the system.

+The process to be killed in an out-of-memory situation is selected among all others

+and is then updated according to its CPU time (utime + stime) and the

+Badness score is divided by the square root of the CPU time and then by
+the double square root of the run time.

+The lowmemorykiller driver lets user-space specify a set of memory thresholds
+where processes with a range of oom_adj values will get killed. Specify the
+minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the
+number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both
+files take a comma separated list of numbers in ascending order.
+
+For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
+"1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes
+with a oom_adj value of 8 or higher when the free memory drops below 4096 pages
+and kill processes with a oom_adj value of 0 or higher when the free memory
+drops below 1024 pages.
+
+The driver considers memory used for caches to be free, but if a large
+percentage of the cached memory is locked this can be very inaccurate
+and processes may not get killed until the normal oom killer is triggered.
