+Hierarchical Cgroups
+====================
+- Currently none of the IO control policy supports hierarhical groups. But
+ cgroup interface does allow creation of hierarhical cgroups and internally
+ IO policies treat them as flat hierarchy.
+
+ So this patch will allow creation of cgroup hierarhcy but at the backend
+ everything will be treated as flat. So if somebody created a hierarchy like
+ as follows.
+
+ root
+ / \
+ test1 test2
+ |
+ test3
+
+ CFQ and throttling will practically treat all groups at same level.
+
+ pivot
+ / | \ \
+ root test1 test2 test3
+
+ Down the line we can implement hierarchical accounting/control support
+ and also introduce a new cgroup file "use_hierarchy" which will control
+ whether cgroup hierarchy is viewed as flat or hierarchical by the policy..
+ This is how memory controller also has implemented the things.

+Kernel driver for the NXP Semiconductors PN544 Near Field
+Communication chip
+
+Author: Jari Vanhala
+Contact: Matti Aaltonen (matti.j.aaltonen at nokia.com)
+
+General
+-------
+
+The PN544 is an integrated transmission module for contactless
+communication. The driver goes under drives/nfc/ and is compiled as a
+module named "pn544". It registers a misc device and creates a device
+file named "/dev/pn544".
+
+Host Interfaces: I2C, SPI and HSU, this driver supports currently only I2C.
+
+The Interface
+-------------
+
+The driver offers a sysfs interface for a hardware test and an IOCTL
+interface for selecting between two operating modes. There are read,
+write and poll functions for transferring messages. The two operating
+modes are the normal (HCI) mode and the firmware update mode.
+
+PN544 is controlled by sending messages from the userspace to the
+chip. The main function of the driver is just to pass those messages
+without caring about the message content.
+
+
+Protocols
+---------
+
+In the normal (HCI) mode and in the firmware update mode read and
+write functions behave a bit differently because the message formats
+or the protocols are different.
+
+In the normal (HCI) mode the protocol used is derived from the ETSI
+HCI specification. The firmware is updated using a specific protocol,
+which is different from HCI.
+
+HCI messages consist of an eight bit header and the message body. The
+header contains the message length. Maximum size for an HCI message is
+33. In HCI mode sent messages are tested for a correct
+checksum. Firmware update messages have the length in the second (MSB)
+and third (LSB) bytes of the message. The maximum FW message length is
+1024 bytes.
+
+For the ETSI HCI specification see
+http://www.etsi.org/WebSite/Technologies/ProtocolSpecification.aspx
+
+The Hardware Test
+-----------------
+
+The idea of the test is that it can performed by reading from the
+corresponding sysfs file. The test is implemented in the board file
+and it should test that PN544 can be put into the firmware update
+mode. If the test is not implemented the sysfs file does not get
+created.
+
+Example:
+> cat /sys/module/pn544/drivers/i2c\:pn544/3-002b/nfc_test
+1
+
+Normal Operation
+----------------
+
+PN544 is powered up when the device file is opened, otherwise it's
+turned off. Only one instance can use the device at a time.
+
+Userspace applications control PN544 with HCI messages. The hardware
+sends an interrupt when data is available for reading. Data is
+physically read when the read function is called by a userspace
+application. Poll() checks the read interrupt state. Configuration and
+self testing are also done from the userspace using read and write.
+
+Example platform data:
+
+static int rx71_pn544_nfc_request_resources(struct i2c_client *client)
+{
+ /* Get and setup the HW resources for the device */
+}
+
+static void rx71_pn544_nfc_free_resources(void)
+{
+ /* Release the HW resources */
+}
+
+static void rx71_pn544_nfc_enable(int fw)
+{
+ /* Turn the device on */
+}
+
+static int rx71_pn544_nfc_test(void)
+{
+ /*
+ * Put the device into the FW update mode
+ * and then back to the normal mode.
+ * Check the behavior and return one on success,
+ * zero on failure.
+ */
+}
+
+static void rx71_pn544_nfc_disable(void)
+{
+ /* turn the power off */
+}
+
+static struct pn544_nfc_platform_data rx71_nfc_data = {
+ .request_resources = rx71_pn544_nfc_request_resources,
+ .free_resources = rx71_pn544_nfc_free_resources,
+ .enable = rx71_pn544_nfc_enable,
+ .test = rx71_pn544_nfc_test,
+ .disable = rx71_pn544_nfc_disable,

+----------
+
+Sometimes one needs to be able not only to catch PPS signals but to produce
+them also. For example, running a distributed simulation, which requires
+computers' clock to be synchronized very tightly. One way to do this is to
+invent some complicated hardware solutions but it may be neither necessary
+nor affordable. The cheap way is to load a PPS generator on one of the
+computers (master) and PPS clients on others (slaves), and use very simple
+cables to deliver signals using parallel ports, for example.

+Please note that parallel port interrupt occurs only on high->low transition,
+so it is used for PPS assert edge. PPS clear edge can be determined only
+using polling in the interrupt handler which actually can be done way more
+precisely because interrupt handling delays can be quite big and random. So
+current parport PPS generator implementation (pps_gen_parport module) is
+geared towards using the clear edge for time synchronization.
+
+Clear edge polling is done with disabled interrupts so it's better to select
+delay between assert and clear edge as small as possible to reduce system
+latencies. But if it is too small slave won't be able to capture clear edge
+transition. The default of 30us should be good enough in most situations.
+The delay can be selected using 'delay' pps_gen_parport module parameter.

+
+Description
+-----------
+
+Support is provided through the sysfs w1_slave file. Each opening and
+read sequence of w1_slave file initiates the read of counters and ram
+available in DS2423 pages 12 - 15.
+
+Result of each page is provided as an ASCII output where each counter
+value and associated ram buffer is outpputed to own line.
+
+Each lines will contain the values of 42 bytes read from the counter and
+memory page along the crc=YES or NO for indicating whether the read operation
+was successfull and CRC matched.
+If the operation was successfull, there is also in the end of each line
+a counter value expressed as an integer after c=
+
+Meaning of 42 bytes represented is following:
+ - 1 byte from ram page
+ - 4 bytes for the counter value
+ - 4 zero bytes
+ - 2 bytes for crc16 which was calculated from the data read since the previous crc bytes
+ - 31 remaining bytes from the ram page
+ - crc=YES/NO indicating whether read was ok and crc matched
+ - c=<int> current counter value
+
+example from the successfull read:

+
+XZ data compression in Linux
+============================
+
+Introduction
+
+ XZ is a general purpose data compression format with high compression
+ ratio and relatively fast decompression. The primary compression
+ algorithm (filter) is LZMA2. Additional filters can be used to improve
+ compression ratio even further. E.g. Branch/Call/Jump (BCJ) filters
+ improve compression ratio of executable data.
+
+ The XZ decompressor in Linux is called XZ Embedded. It supports
+ the LZMA2 filter and optionally also BCJ filters. CRC32 is supported
+ for integrity checking. The home page of XZ Embedded is at
+ <http://tukaani.org/xz/embedded.html>, where you can find the
+ latest version and also information about using the code outside
+ the Linux kernel.
+
+ For userspace, XZ Utils provide a zlib-like compression library
+ and a gzip-like command line tool. XZ Utils can be downloaded from
+ <http://tukaani.org/xz/>.
+
+XZ related components in the kernel
+
+ The xz_dec module provides XZ decompressor with single-call (buffer
+ to buffer) and multi-call (stateful) APIs. The usage of the xz_dec
+ module is documented in include/linux/xz.h.
+
+ The xz_dec_test module is for testing xz_dec. xz_dec_test is not
+ useful unless you are hacking the XZ decompressor. xz_dec_test
+ allocates a char device major dynamically to which one can write
+ .xz files from userspace. The decompressed output is thrown away.
+ Keep an eye on dmesg to see diagnostics printed by xz_dec_test.
+ See the xz_dec_test source code for the details.
+
+ For decompressing the kernel image, initramfs, and initrd, there
+ is a wrapper function in lib/decompress_unxz.c. Its API is the
+ same as in other decompress_*.c files, which is defined in
+ include/linux/decompress/generic.h.
+
+ scripts/xz_wrap.sh is a wrapper for the xz command line tool found
+ from XZ Utils. The wrapper sets compression options to values suitable
+ for compressing the kernel image.
+
+ For kernel makefiles, two commands are provided for use with
+ $(call if_needed). The kernel image should be compressed with
+ $(call if_needed,xzkern) which will use a BCJ filter and a big LZMA2
+ dictionary. It will also append a four-byte trailer containing the
+ uncompressed size of the file, which is needed by the boot code.
+ Other things should be compressed with $(call if_needed,xzmisc)
+ which will use no BCJ filter and 1 MiB LZMA2 dictionary.
+
+Notes on compression options
+
+ Since the XZ Embedded supports only streams with no integrity check or
+ CRC32, make sure that you don't use some other integrity check type
+ when encoding files that are supposed to be decoded by the kernel. With
+ liblzma, you need to use either LZMA_CHECK_NONE or LZMA_CHECK_CRC32
+ when encoding. With the xz command line tool, use --check=none or
+ --check=crc32.
+
+ Using CRC32 is strongly recommended unless there is some other layer
+ which will verify the integrity of the uncompressed data anyway.
+ Double checking the integrity would probably be waste of CPU cycles.
+ Note that the headers will always have a CRC32 which will be validated
+ by the decoder; you can only change the integrity check type (or
+ disable it) for the actual uncompressed data.
+
+ In userspace, LZMA2 is typically used with dictionary sizes of several
+ megabytes. The decoder needs to have the dictionary in RAM, thus big
+ dictionaries cannot be used for files that are intended to be decoded
+ by the kernel. 1 MiB is probably the maximum reasonable dictionary
+ size for in-kernel use (maybe more is OK for initramfs). The presets
+ in XZ Utils may not be optimal when creating files for the kernel,
+ so don't hesitate to use custom settings. Example:
+
+ xz --check=crc32 --lzma2=dict=512KiB inputfile
+
+ An exception to above dictionary size limitation is when the decoder
+ is used in single-call mode. Decompressing the kernel itself is an
+ example of this situation. In single-call mode, the memory usage
+ doesn't depend on the dictionary size, and it is perfectly fine to
+ use a big dictionary: for maximum compression, the dictionary should
+ be at least as big as the uncompressed data itself.
+
+Future plans
+
+ Creating a limited XZ encoder may be considered if people think it is
+ useful. LZMA2 is slower to compress than e.g. Deflate or LZO even at
+ the fastest settings, so it isn't clear if LZMA2 encoder is wanted
+ into the kernel.
+
+ Support for limited random-access reading is planned for the
+ decompression code. I don't know if it could have any use in the
+ kernel, but I know that it would be useful in some embedded projects
+ outside the Linux kernel.
+
+Conformance to the .xz file format specification
+
+ There are a couple of corner cases where things have been simplified
+ at expense of detecting errors as early as possible. These should not
+ matter in practice all, since they don't cause security issues. But
+ it is good to know this if testing the code e.g. with the test files
+ from XZ Utils.
+
+Reporting bugs
+
+ Before reporting a bug, please check that it's not fixed already
+ at upstream. See <http://tukaani.org/xz/embedded.html> to get the
+ latest code.
+
+ Report bugs to <lasse.collin@tukaani.org> or visit #tukaani on
+ Freenode and talk to Larhzu. I don't actively read LKML or other
+ kernel-related mailing lists, so if there's something I should know,
+ you should email to me personally or use IRC.
+
+ Don't bother Igor Pavlov with questions about the XZ implementation
+ in the kernel or about XZ Utils. While these two implementations
+ include essential code that is directly based on Igor Pavlov's code,
+ these implementations aren't maintained nor supported by him.

- * day/month/year calendar data.
- *
- * - Some hardware uses illegal values as "wildcard" match
- * values, which non-Linux firmware (like a BIOS) may try
- * to set up as e.g. "alarm 15 minutes after each hour".
- * Linux uses only oneshot alarms.
- *
- * When we see that here, we deal with it by using values from
- * a current RTC timestamp for any missing (-1) values. The
- * RTC driver prevents "periodic alarm" modes.
- *
- * But this can be racey, because some fields of the RTC timestamp
- * may have wrapped in the interval since we read the RTC alarm,
- * which would lead to us inserting inconsistent values in place
- * of the -1 fields.
- *
- * Reading the alarm and timestamp in the reverse sequence
- * would have the same race condition, and not solve the issue.
- *
- * So, we must first read the RTC timestamp,
- * then read the RTC alarm value,
- * and then read a second RTC timestamp.
- *
- * If any fields of the second timestamp have changed
- * when compared with the first timestamp, then we know
- * our timestamp may be inconsistent with that used by
- * the low-level rtc_read_alarm_internal() function.
- *
- * So, when the two timestamps disagree, we just loop and do
- * the process again to get a fully consistent set of values.
- *
- * This could all instead be done in the lower level driver,
- * but since more than one lower level RTC implementation needs it,
- * then it's probably best best to do it here instead of there..

- * Values for the BitRate Register (SCBRR)

- * The values are actually divisors for a frequency which can
- * be internal to the SH3 (14.7456MHz) or derived from an external
- * clock source. This driver assumes the internal clock is used;
- * to support using an external clock source, config options or

- *
- * Also, to support speeds below 2400 (why?) the lower 2 bits of

- * -- Greg Banks 27Feb2000
- *
- * Answer: The SCBRR register is only eight bits, and the value in
- * it gets larger with lower baud rates. At around 2400 (depending on
- * the peripherial module clock) you run out of bits. However the
- * lower two bits of SCSMR allow the module clock to be divided down,
- * scaling the value which is needed in SCBRR.

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

+ * @XZ_MEM_ERROR: Allocating memory failed. This return code is

+ * @XZ_OPTIONS_ERROR: This implementation doesn't support the requested

+ * is full while at least one output byte is still pending. Assuming your
+ * code is not buggy, you can get this error only when decoding a compressed
+ * stream that is truncated or otherwise corrupt.
+ *
+ * In single-call mode, XZ_BUF_ERROR is returned only when the output buffer
+ * is too small or the compressed input is corrupt in a way that makes the

+/*
+ * Important notes about in-place decompression
+ *
+ * At least on x86, the kernel is decompressed in place: the compressed data
+ * is placed to the end of the output buffer, and the decompressor overwrites
+ * most of the compressed data. There must be enough safety margin to
+ * guarantee that the write position is always behind the read position.
+ *
+ * The safety margin for XZ with LZMA2 or BCJ+LZMA2 is calculated below.
+ * Note that the margin with XZ is bigger than with Deflate (gzip)!
+ *
+ * The worst case for in-place decompression is that the beginning of
+ * the file is compressed extremely well, and the rest of the file is
+ * uncompressible. Thus, we must look for worst-case expansion when the
+ * compressor is encoding uncompressible data.
+ *
+ * The structure of the .xz file in case of a compresed kernel is as follows.
+ * Sizes (as bytes) of the fields are in parenthesis.
+ *
+ * Stream Header (12)
+ * Block Header:
+ * Block Header (8-12)
+ * Compressed Data (N)
+ * Block Padding (0-3)
+ * CRC32 (4)
+ * Index (8-20)
+ * Stream Footer (12)
+ *
+ * Normally there is exactly one Block, but let's assume that there are
+ * 2-4 Blocks just in case. Because Stream Header and also Block Header
+ * of the first Block don't make the decompressor produce any uncompressed
+ * data, we can ignore them from our calculations. Block Headers of possible
+ * additional Blocks have to be taken into account still. With these
+ * assumptions, it is safe to assume that the total header overhead is
+ * less than 128 bytes.
+ *
+ * Compressed Data contains LZMA2 or BCJ+LZMA2 encoded data. Since BCJ
+ * doesn't change the size of the data, it is enough to calculate the
+ * safety margin for LZMA2.
+ *
+ * LZMA2 stores the data in chunks. Each chunk has a header whose size is
+ * a maximum of 6 bytes, but to get round 2^n numbers, let's assume that
+ * the maximum chunk header size is 8 bytes. After the chunk header, there
+ * may be up to 64 KiB of actual payload in the chunk. Often the payload is
+ * quite a bit smaller though; to be safe, let's assume that an average
+ * chunk has only 32 KiB of payload.
+ *
+ * The maximum uncompressed size of the payload is 2 MiB. The minimum
+ * uncompressed size of the payload is in practice never less than the
+ * payload size itself. The LZMA2 format would allow uncompressed size
+ * to be less than the payload size, but no sane compressor creates such
+ * files. LZMA2 supports storing uncompressible data in uncompressed form,
+ * so there's never a need to create payloads whose uncompressed size is
+ * smaller than the compressed size.
+ *
+ * The assumption, that the uncompressed size of the payload is never
+ * smaller than the payload itself, is valid only when talking about
+ * the payload as a whole. It is possible that the payload has parts where
+ * the decompressor consumes more input than it produces output. Calculating
+ * the worst case for this would be tricky. Instead of trying to do that,
+ * let's simply make sure that the decompressor never overwrites any bytes
+ * of the payload which it is currently reading.
+ *
+ * Now we have enough information to calculate the safety margin. We need
+ * - 128 bytes for the .xz file format headers;
+ * - 8 bytes per every 32 KiB of uncompressed size (one LZMA2 chunk header
+ * per chunk, each chunk having average payload size of 32 KiB); and
+ * - 64 KiB (biggest possible LZMA2 chunk payload size) to make sure that
+ * the decompressor never overwrites anything from the LZMA2 chunk
+ * payload it is currently reading.
+ *
+ * We get the following formula:
+ *
+ * safety_margin = 128 + uncompressed_size * 8 / 32768 + 65536
+ * = 128 + (uncompressed_size >> 12) + 65536
+ *
+ * For comparision, according to arch/x86/boot/compressed/misc.c, the
+ * equivalent formula for Deflate is this:
+ *
+ * safety_margin = 18 + (uncompressed_size >> 12) + 32768
+ *
+ * Thus, when updating Deflate-only in-place kernel decompressor to
+ * support XZ, the fixed overhead has to be increased from 18+32768 bytes
+ * to 128+65536 bytes.

+.TH TURBOSTAT 8
+.SH NAME
+turbostat \- Report processor frequency and idle statistics
+.SH SYNOPSIS
+.ft B
+.B turbostat
+.RB [ "\-v" ]
+.RB [ "\-M MSR#" ]
+.RB command
+.br
+.B turbostat
+.RB [ "\-v" ]
+.RB [ "\-M MSR#" ]
+.RB [ "\-i interval_sec" ]
+.SH DESCRIPTION
+\fBturbostat \fP reports processor topology, frequency
+and idle power state statistics on modern X86 processors.
+Either \fBcommand\fP is forked and statistics are printed
+upon its completion, or statistics are printed periodically.
+
+\fBturbostat \fP
+requires that the processor
+supports an "invariant" TSC, plus the APERF and MPERF MSRs.
+\fBturbostat \fP will report idle cpu power state residency
+on processors that additionally support C-state residency counters.
+
+.SS Options
+The \fB-v\fP option increases verbosity.
+.PP
+The \fB-M MSR#\fP option dumps the specified MSR,
+in addition to the usual frequency and idle statistics.
+.PP
+The \fB-i interval_sec\fP option prints statistics every \fiinterval_sec\fP seconds.
+The default is 5 seconds.
+.PP
+The \fBcommand\fP parameter forks \fBcommand\fP and upon its exit,
+displays the statistics gathered since it was forked.
+.PP
+.SH FIELD DESCRIPTIONS
+.nf
+\fBpkg\fP processor package number.
+\fBcore\fP processor core number.
+\fBCPU\fP Linux CPU (logical processor) number.
+\fB%c0\fP percent of the interval that the CPU retired instructions.
+\fBGHz\fP average clock rate while the CPU was in c0 state.
+\fBTSC\fP average GHz that the TSC ran during the entire interval.
+\fB%c1, %c3, %c6\fP show the percentage residency in hardware core idle states.
+\fB%pc3, %pc6\fP percentage residency in hardware package idle states.
+.fi
+.PP
+.SH EXAMPLE
+Without any parameters, turbostat prints out counters ever 5 seconds.
+(override interval with "-i sec" option, or specify a command
+for turbostat to fork).
+
+The first row of statistics reflect the average for the entire system.
+Subsequent rows show per-CPU statistics.

+.SH VERBOSE EXAMPLE
+The "-v" option adds verbosity to the output:
+
+.nf
+GenuineIntel 11 CPUID levels; family:model:stepping 0x6:2c:2 (6:44:2)
+12 * 133 = 1600 MHz max efficiency
+25 * 133 = 3333 MHz TSC frequency
+26 * 133 = 3467 MHz max turbo 4 active cores
+26 * 133 = 3467 MHz max turbo 3 active cores
+27 * 133 = 3600 MHz max turbo 2 active cores
+27 * 133 = 3600 MHz max turbo 1 active cores
+
+.fi
+The \fBmax efficiency\fP frequency, a.k.a. Low Frequency Mode, is the frequency
+available at the minimum package voltage. The \fBTSC frequency\fP is the nominal
+maximum frequency of the processor if turbo-mode were not available. This frequency
+should be sustainable on all CPUs indefinitely, given nominal power and cooling.
+The remaining rows show what maximum turbo frequency is possible
+depending on the number of idle cores. Note that this information is
+not available on all processors.
+.SH FORK EXAMPLE
+If turbostat is invoked with a command, it will fork that command
+and output the statistics gathered when the command exits.
+eg. Here a cycle soaker is run on 1 CPU (see %c0) for a few seconds
+until ^C while the other CPUs are mostly idle:
+
+.nf
+[root@x980 lenb]# ./turbostat cat /dev/zero > /dev/null

+.fi
+Above the cycle soaker drives cpu9 up 3.6 Ghz turbo limit
+while the other processors are generally in various states of idle.
+
+Note that cpu3 is an HT sibling sharing core9
+with cpu9, and thus it is unable to get to an idle state
+deeper than c1 while cpu9 is busy.
+
+Note that turbostat reports average GHz of 3.61, while
+the arithmetic average of the GHz column above is 3.24.
+This is a weighted average, where the weight is %c0. ie. it is the total number of
+un-halted cycles elapsed per time divided by the number of CPUs.
+.SH NOTES
+
+.B "turbostat "
+must be run as root.
+
+.B "turbostat "
+reads hardware counters, but doesn't write them.
+So it will not interfere with the OS or other programs, including
+multiple invocations of itself.
+
+\fBturbostat \fP
+may work poorly on Linux-2.6.20 through 2.6.29,
+as \fBacpi-cpufreq \fPperiodically cleared the APERF and MPERF
+in those kernels.
+
+The APERF, MPERF MSRs are defined to count non-halted cycles.
+Although it is not guaranteed by the architecture, turbostat assumes
+that they count at TSC rate, which is true on all processors tested to date.

+.SH DESCRIPTION
+\fBx86_energy_perf_policy\fP
+allows software to convey
+its policy for the relative importance of performance
+versus energy savings to the processor.
+
+The processor uses this information in model-specific ways
+when it must select trade-offs between performance and
+energy efficiency.
+
+This policy hint does not supersede Processor Performance states
+(P-states) or CPU Idle power states (C-states), but allows
+software to have influence where it would otherwise be unable
+to express a preference.
+
+For example, this setting may tell the hardware how
+aggressively or conservatively to control frequency
+in the "turbo range" above the explicitly OS-controlled
+P-state frequency range. It may also tell the hardware
+how aggressively is should enter the OS requested C-states.
+
+Support for this feature is indicated by CPUID.06H.ECX.bit3
+per the Intel Architectures Software Developer's Manual.
+
+.SS Options
+\fB-c\fP limits operation to a single CPU.
+The default is to operate on all CPUs.
+Note that MSR_IA32_ENERGY_PERF_BIAS is defined per
+logical processor, but that the initial implementations
+of the MSR were shared among all processors in each package.
+.PP
+\fB-v\fP increases verbosity. By default
+x86_energy_perf_policy is silent.
+.PP
+\fB-r\fP is for "read-only" mode - the unchanged state
+is read and displayed.
+.PP
+.I performance
+Set a policy where performance is paramount.
+The processor will be unwilling to sacrifice any performance
+for the sake of energy saving. This is the hardware default.
+.PP
+.I normal
+Set a policy with a normal balance between performance and energy efficiency.
+The processor will tolerate minor performance compromise
+for potentially significant energy savings.
+This reasonable default for most desktops and servers.
+.PP
+.I powersave
+Set a policy where the processor can accept
+a measurable performance hit to maximize energy efficiency.
+.PP
+.I n
+Set MSR_IA32_ENERGY_PERF_BIAS to the specified number.
+The range of valid numbers is 0-15, where 0 is maximum
+performance and 15 is maximum energy efficiency.

+# options, with the following exceptions:
+#
+# LOG_FILE
+# CLEAR_LOG
+# POWEROFF_ON_SUCCESS
+# REBOOT_ON_SUCCESS
+#
+# Test specific options are set after the label:
+#
+# TEST_START
+#
+# The options after a TEST_START label are specific to that test.
+# Each TEST_START label will set up a new test. If you want to
+# perform a test more than once, you can add the ITERATE label
+# to it followed by the number of times you want that test
+# to iterate. If the ITERATE is left off, the test will only
+# be performed once.
+#
+# TEST_START ITERATE 10
+#
+# You can skip a test by adding SKIP (before or after the ITERATE
+# and number)
+#
+# TEST_START SKIP
+#
+# TEST_START SKIP ITERATE 10
+#
+# TEST_START ITERATE 10 SKIP

+# The SKIP label causes the options and the test itself to be ignored.
+# This is useful to set up several different tests in one config file, and
+# only enabling the ones you want to use for a current test run.
+#
+# You can add default options anywhere in the file as well
+# with the DEFAULTS tag. This allows you to have default options

+# The above will run the first test with MIN_CONFIG set to
+# /home/test/config-test-1. Then 10 tests will be executed

+# If you specify grub, it will assume grub version 1

+#### Per test run options ####
+# The following options are only allowed in TEST_START sections.
+# They are ignored in the DEFAULTS sections.
+#
+# All of these are optional and undefined by default, although
+# some of these options are required for TEST_TYPE of patchcheck
+# and bisect.
+#
+#
+# CHECKOUT = branch
+#
+# If the BUILD_DIR is a git repository, then you can set this option
+# to checkout the given branch before running the TEST. If you
+# specify this for the first run, that branch will be used for
+# all preceding tests until a new CHECKOUT is set.
+#
+#
+#
+# For TEST_TYPE = patchcheck
+#
+# This expects the BUILD_DIR to be a git repository, and
+# will checkout the PATCHCHECK_START commit.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# The MIN_CONFIG will be used for all builds of the patchcheck. The build type
+# used for patchcheck is oldconfig.
+#
+# PATCHCHECK_START is required and is the first patch to
+# test (the SHA1 of the commit). You may also specify anything
+# that git checkout allows (branch name, tage, HEAD~3).
+#
+# PATCHCHECK_END is the last patch to check (default HEAD)
+#
+# PATCHCHECK_TYPE is required and is the type of test to run:
+# build, boot, test.
+#
+# Note, the build test will look for warnings, if a warning occurred
+# in a file that a commit touches, the build will fail.
+#
+# If BUILD_NOCLEAN is set, then make mrproper will not be run on
+# any of the builds, just like all other TEST_TYPE tests. But
+# what makes patchcheck different from the other tests, is if
+# BUILD_NOCLEAN is not set, only the first and last patch run
+# make mrproper. This helps speed up the test.
+#
+# Example:
+# TEST_START
+# TEST_TYPE = patchcheck
+# CHECKOUT = mybranch
+# PATCHCHECK_TYPE = boot
+# PATCHCHECK_START = 747e94ae3d1b4c9bf5380e569f614eb9040b79e7
+# PATCHCHECK_END = HEAD~2
+#
+#
+#
+# For TEST_TYPE = bisect
+#
+# You can specify a git bisect if the BUILD_DIR is a git repository.
+# The MIN_CONFIG will be used for all builds of the bisect. The build type
+# used for bisecting is oldconfig.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# BISECT_TYPE is the type of test to perform:
+# build - bad fails to build
+# boot - bad builds but fails to boot
+# test - bad boots but fails a test
+#
+# BISECT_GOOD is the commit (SHA1) to label as good (accepts all git good commit types)
+# BISECT_BAD is the commit to label as bad (accepts all git bad commit types)
+#
+# The above three options are required for a bisect operation.
+#
+# BISECT_REPLAY = /path/to/replay/file (optional, default undefined)
+#
+# If an operation failed in the bisect that was not expected to
+# fail. Then the test ends. The state of the BUILD_DIR will be
+# left off at where the failure occurred. You can examine the
+# reason for the failure, and perhaps even find a git commit
+# that would work to continue with. You can run:
+#
+# git bisect log > /path/to/replay/file
+#
+# The adding:
+#
+# BISECT_REPLAY= /path/to/replay/file
+#
+# And running the test again. The test will perform the initial
+# git bisect start, git bisect good, and git bisect bad, and
+# then it will run git bisect replay on this file, before
+# continuing with the bisect.
+#
+# BISECT_START = commit (optional, default undefined)
+#
+# As with BISECT_REPLAY, if the test failed on a commit that
+# just happen to have a bad commit in the middle of the bisect,
+# and you need to skip it. If BISECT_START is defined, it
+# will checkout that commit after doing the initial git bisect start,
+# git bisect good, git bisect bad, and running the git bisect replay
+# if the BISECT_REPLAY is set.
+#
+# BISECT_REVERSE = 1 (optional, default 0)
+#
+# In those strange instances where it was broken forever
+# and you are trying to find where it started to work!
+# Set BISECT_GOOD to the commit that was last known to fail
+# Set BISECT_BAD to the commit that is known to start working.
+# With BISECT_REVERSE = 1, The test will consider failures as
+# good, and success as bad.
+#
+# BISECT_CHECK = 1 (optional, default 0)
+#
+# Just to be sure the good is good and bad is bad, setting
+# BISECT_CHECK to 1 will start the bisect by first checking
+# out BISECT_BAD and makes sure it fails, then it will check
+# out BISECT_GOOD and makes sure it succeeds before starting
+# the bisect (it works for BISECT_REVERSE too).
+#
+# You can limit the test to just check BISECT_GOOD or
+# BISECT_BAD with BISECT_CHECK = good or
+# BISECT_CHECK = bad, respectively.
+#
+# Example:
+# TEST_START
+# TEST_TYPE = bisect
+# BISECT_GOOD = v2.6.36
+# BISECT_BAD = b5153163ed580e00c67bdfecb02b2e3843817b3e
+# BISECT_TYPE = build
+# MIN_CONFIG = /home/test/config-bisect
+#
+#
+#
+# For TEST_TYPE = config_bisect
+#
+# In those cases that you have two different configs. One of them
+# work, the other does not, and you do not know what config causes
+# the problem.
+# The TEST_TYPE config_bisect will bisect the bad config looking for
+# what config causes the failure.
+#
+# The way it works is this:
+#
+# First it finds a config to work with. Since a different version, or
+# MIN_CONFIG may cause different dependecies, it must run through this
+# preparation.
+#
+# Overwrites any config set in the bad config with a config set in
+# either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs
+# are minimal and do not disable configs you want to test:
+# (ie. # CONFIG_FOO is not set).
+#
+# An oldconfig is run on the bad config and any new config that
+# appears will be added to the configs to test.
+#
+# Finally, it generates a config with the above result and runs it
+# again through make oldconfig to produce a config that should be
+# satisfied by kconfig.
+#
+# Then it starts the bisect.
+#
+# The configs to test are cut in half. If all the configs in this
+# half depend on a config in the other half, then the other half
+# is tested instead. If no configs are enabled by either half, then
+# this means a circular dependency exists and the test fails.
+#
+# A config is created with the test half, and the bisect test is run.
+#
+# If the bisect succeeds, then all configs in the generated config
+# are removed from the configs to test and added to the configs that
+# will be enabled for all builds (they will be enabled, but not be part
+# of the configs to examine).
+#
+# If the bisect fails, then all test configs that were not enabled by
+# the config file are removed from the test. These configs will not
+# be enabled in future tests. Since current config failed, we consider
+# this to be a subset of the config that we started with.
+#
+# When we are down to one config, it is considered the bad config.
+#
+# Note, the config chosen may not be the true bad config. Due to
+# dependencies and selections of the kbuild system, mulitple
+# configs may be needed to cause a failure. If you disable the
+# config that was found and restart the test, if the test fails
+# again, it is recommended to rerun the config_bisect with a new
+# bad config without the found config enabled.
+#
+# The option BUILD_TYPE will be ignored.
+#
+# CONFIG_BISECT_TYPE is the type of test to perform:
+# build - bad fails to build
+# boot - bad builds but fails to boot
+# test - bad boots but fails a test
+#
+# CONFIG_BISECT is the config that failed to boot
+#
+# Example:
