 1. Introduction

 Owing to the simplicity and near universality of the parallel port interface
 to personal computers, many external devices such as portable hard-disk,
 CD-ROM, LS-120 and tape drives use the parallel port to connect to their
 host computer.  While some devices (notably scanners) use ad-hoc methods

 subsystem, is actually structured in three parts.   There is a base
 paride module which provides a registry and some common methods for

-   Comments:
-
-    * This line of SoCs originates from the XScale family developed by
-      Intel and acquired by Marvell in ~2006. The PXA21x, PXA25x,
-      PXA26x, PXA27x, PXA3xx and PXA93x were developed by Intel, while
-      the later PXA95x were developed by Marvell.
-
-    * Due to their XScale origin, these SoCs have virtually nothing in
-      common with the other (Kirkwood, Dove, etc.) families of Marvell
-      SoCs, except with the MMP/MMP2 family of SoCs.

-CPU Cores
----------
-
-The XScale cores were designed by Intel, and shipped by Marvell in the older
-PXA processors. Feroceon is a Marvell designed core that developed in-house,
-and that evolved into Sheeva. The XScale and Feroceon cores were phased out
-over time and replaced with Sheeva cores in later products, which subsequently
-got replaced with licensed ARM Cortex-A cores.

-
-Long-term plans
----------------
-
- * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ into the
-   mach-mvebu/ to support all SoCs from the Marvell EBU (Engineering
-   Business Unit) in a single mach-<foo> directory. The plat-orion/
-   would therefore disappear.
-
- * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
-   directory. The plat-pxa/ would therefore disappear.

-The SA1100 serial port had its major/minor numbers officially assigned:

-> Date: Sun, 24 Sep 2000 21:40:27 -0700
-> From: H. Peter Anvin <hpa@transmeta.com>

-> Cc: Device List Maintainer <device@lanana.org>
-> Subject: Re: device
-> 
-> Okay.  Note that device numbers 204 and 205 are used for "low density
-> serial devices", so you will have a range of minors on those majors (the
-> tty device layer handles this just fine, so you don't have to worry about
-> doing anything special.)
-> 
-> So your assignments are:
-> 
-> 204 char        Low-density serial ports
->                   5 = /dev/ttySA0               SA1100 builtin serial port 0
->                   6 = /dev/ttySA1               SA1100 builtin serial port 1
->                   7 = /dev/ttySA2               SA1100 builtin serial port 2
-> 
-> 205 char        Low-density serial ports (alternate device)
->                   5 = /dev/cusa0                Callout device for ttySA0
->                   6 = /dev/cusa1                Callout device for ttySA1
->                   7 = /dev/cusa2                Callout device for ttySA2

-
-You must create those inodes in /dev on the root filesystem used
-by your SA1100-based device:
-
-        mknod ttySA0 c 204 5
-        mknod ttySA1 c 204 6
-        mknod ttySA2 c 204 7
-        mknod cusa0 c 205 5
-        mknod cusa1 c 205 6
-        mknod cusa2 c 205 7
-
-In addition to the creation of the appropriate device nodes above, you
-must ensure your user space applications make use of the correct device
-name. The classic example is the content of the /etc/inittab file where
-you might have a getty process started on ttyS0.  In this case:
-
-- replace occurrences of ttyS0 with ttySA0, ttyS1 with ttySA1, etc.
-
-- don't forget to add 'ttySA0', 'console', or the appropriate tty name
-  in /etc/securetty for root to be allowed to login as well.

+ARM Marvell SoCs
+================
+
+This document lists all the ARM Marvell SoCs that are currently
+supported in mainline by the Linux kernel. As the Marvell families of
+SoCs are large and complex, it is hard to understand where the support
+for a particular SoC is available in the Linux kernel. This document
+tries to help in understanding where those SoCs are supported, and to
+match them with their corresponding public datasheet, when available.

+ * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ into the
+   mach-mvebu/ to support all SoCs from the Marvell EBU (Engineering

+   would therefore disappear.
+
+ * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
+   directory. The plat-pxa/ would therefore disappear.

+You must create those inodes in /dev on the root filesystem used
+by your SA1100-based device::
+
+        mknod ttySA0 c 204 5
+        mknod ttySA1 c 204 6
+        mknod ttySA2 c 204 7

+        mknod cusa1 c 205 6
+        mknod cusa2 c 205 7
+
+In addition to the creation of the appropriate device nodes above, you
+must ensure your user space applications make use of the correct device
+name. The classic example is the content of the /etc/inittab file where
+you might have a getty process started on ttyS0.
+
+In this case:
+
+- replace occurrences of ttyS0 with ttySA0, ttyS1 with ttySA1, etc.
+
+- don't forget to add 'ttySA0', 'console', or the appropriate tty name
+  in /etc/securetty for root to be allowed to login as well.

+   informs other nodes that a resync is initiated or
    ended so that each node may suspend or resume the region.  Each
    RESYNCING message identifies a range of the devices that the
    sending node is about to resync. This overrides any previous
    notification from that node: only one ranged can be resynced at a
    time per-node.

 3.2 Communication mechanism
+---------------------------
 
  The DLM LVB is used to communicate within nodes of the cluster. There
  are three resources used for the purpose:
 
-  3.2.1 token: The resource which protects the entire communication
+3.2.1 token
+^^^^^^^^^^^
+   The resource which protects the entire communication
    system. The node having the token resource is allowed to
    communicate.
 
-  3.2.2 message: The lock resource which carries the data to
-   communicate.
+3.2.2 message
+^^^^^^^^^^^^^
+   The lock resource which carries the data to communicate.
 
-  3.2.3 ack: The resource, acquiring which means the message has been
+3.2.3 ack
+^^^^^^^^^
+
+   The resource, acquiring which means the message has been
    acknowledged by all nodes in the cluster. The BAST of the resource
    is used to inform the receiving node that a node wants to
    communicate.
 
 The algorithm is:
 
- 1. receive status - all nodes have concurrent-reader lock on "ack".

 Rationale
 =========
 
 How significant is the cache maintenance overhead?
+
 It depends. Fast eMMC and multiple cache levels with speculative cache
 pre-fetch makes the cache overhead relatively significant. If the DMA
 preparations for the next request are done in parallel with the current
 transfer, the DMA preparation overhead would not affect the MMC performance.
+
 The intention of non-blocking (asynchronous) MMC requests is to minimize the
 time between when an MMC request ends and another MMC request begins.

 Using mmc_wait_for_req(), the MMC controller is idle while dma_map_sg and
 dma_unmap_sg are processing. Using non-blocking MMC requests makes it

 The first request in a series of requests can't be prepared in parallel
 with the previous transfer, since there is no previous request.

 The argument is_first_req in pre_req() indicates that there is no previous
 request. The host driver may optimize for this scenario to minimize
 the performance loss. A way to optimize for this is to split the current
 request in two chunks, prepare the first chunk and start the request,
 and finally prepare the second chunk and start the transfer.

 This figure represents a sector of 256 bytes.
 cp is my abbreviation for column parity, rp for row parity.
 
 Let's start to explain column parity.
-cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.
-so the sum of all bit0, bit2, bit4 and bit6 values + cp0 itself is even.
+
+- cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.
+
+  so the sum of all bit0, bit2, bit4 and bit6 values + cp0 itself is even.
+
 Similarly cp1 is the sum of all bit1, bit3, bit5 and bit7.
-cp2 is the parity over bit0, bit1, bit4 and bit5
-cp3 is the parity over bit2, bit3, bit6 and bit7.
-cp4 is the parity over bit0, bit1, bit2 and bit3.
-cp5 is the parity over bit4, bit5, bit6 and bit7.
+
+- cp2 is the parity over bit0, bit1, bit4 and bit5
+- cp3 is the parity over bit2, bit3, bit6 and bit7.
+- cp4 is the parity over bit0, bit1, bit2 and bit3.
+- cp5 is the parity over bit4, bit5, bit6 and bit7.
+
 Note that each of cp0 .. cp5 is exactly one bit.
 
 Row parity actually works almost the same.
-rp0 is the parity of all even bytes (0, 2, 4, 6, ... 252, 254)
-rp1 is the parity of all odd bytes (1, 3, 5, 7, ..., 253, 255)
-rp2 is the parity of all bytes 0, 1, 4, 5, 8, 9, ...
-(so handle two bytes, then skip 2 bytes).
-rp3 is covers the half rp2 does not cover (bytes 2, 3, 6, 7, 10, 11, ...)
-for rp4 the rule is cover 4 bytes, skip 4 bytes, cover 4 bytes, skip 4 etc.
-so rp4 calculates parity over bytes 0, 1, 2, 3, 8, 9, 10, 11, 16, ...)
-and rp5 covers the other half, so bytes 4, 5, 6, 7, 12, 13, 14, 15, 20, ..
+

 The story now becomes quite boring. I guess you get the idea.
-rp6 covers 8 bytes then skips 8 etc
-rp7 skips 8 bytes then covers 8 etc
-rp8 covers 16 bytes then skips 16 etc
-rp9 skips 16 bytes then covers 16 etc
-rp10 covers 32 bytes then skips 32 etc
-rp11 skips 32 bytes then covers 32 etc
-rp12 covers 64 bytes then skips 64 etc
-rp13 skips 64 bytes then covers 64 etc
-rp14 covers 128 bytes then skips 128
-rp15 skips 128 bytes then covers 128
+
+- rp6 covers 8 bytes then skips 8 etc

+- rp13 skips 64 bytes then covers 64 etc

 In the end the parity bits are grouped together in three bytes as
 follows:

 ECC    Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

+=====  ===== ===== ===== ===== ===== ===== ===== =====
 
 I detected after writing this that ST application note AN1823
 (http://www.st.com/stonline/) gives a much
 nicer picture.(but they use line parity as term where I use row parity)
 Oh well, I'm graphically challenged, so suffer with me for a moment :-)

 And I could not reuse the ST picture anyway for copyright reasons.

 In this platform we have four DIMMs and two memory controllers in one
 socket.  Each unique interface (BLK or PMEM) to DPA space is identified
 by a region device with a dynamically assigned id (REGION0 - REGION5).
 
     1. The first portion of DIMM0 and DIMM1 are interleaved as REGION0. A
-    single PMEM namespace is created in the REGION0-SPA-range that spans most

-    interleaved system-physical-address range is reclaimed as BLK-aperture
-    accessed space starting at DPA-offset (a) into each DIMM.  In that

-    could be set to any user-desired name in the LABEL.

 Idle namespaces are automatically created by the kernel if a given
 region has enough available capacity to create a new namespace.
 Namespace instantiation involves finding an idle namespace and
 configuring it.  For the most part the setting of namespace attributes
 can occur in any order, the only constraint is that 'uuid' must be set
 before 'size'.  This enables the kernel to track DPA allocations

 LIBNVDIMM/LIBNDCTL: Block Translation Table "btt"
----------------------------------------------

 A BTT (design document: http://pmem.io/2014/09/23/btt.html) is a stacked
 block device driver that fronts either the whole block device or a
 partition of a block device emitted by either a PMEM or BLK NAMESPACE.

+Intel MID PTI
+=============
+
+The Intel MID PTI project is HW implemented in Intel Atom
+system-on-a-chip designs based on the Parallel Trace
+Interface for MIPI P1149.7 cJTAG standard.  The kernel solution
+for this platform involves the following files::
+
+        ./include/linux/pti.h
+        ./drivers/.../n_tracesink.h
+        ./drivers/.../n_tracerouter.c
+        ./drivers/.../n_tracesink.c
+        ./drivers/.../pti.c
+
+pti.c is the driver that enables various debugging features
+popular on platforms from certain mobile manufacturers.
+n_tracerouter.c and n_tracesink.c allow extra system information to
+be collected and routed to the pti driver, such as trace
+debugging data from a modem.  Although n_tracerouter
+and n_tracesink are a part of the complete PTI solution,
+these two line disciplines can work separately from
+pti.c and route any data stream from one /dev/tty node
+to another /dev/tty node via kernel-space.  This provides
+a stable, reliable connection that will not break unless
+the user-space application shuts down (plus avoids
+kernel->user->kernel context switch overheads of routing
+data).
+
+An example debugging usage for this driver system:
+
+  * Hook /dev/ttyPTI0 to syslogd.  Opening this port will also start
+    a console device to further capture debugging messages to PTI.
+  * Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.
+    This is where n_tracerouter and n_tracesink are used.
+  * Hook /dev/pti to a user-level debugging application for writing
+    to PTI HW.
+  * `Use mipi_` Kernel Driver API in other device drivers for
+    debugging to PTI by first requesting a PTI write address via
+    mipi_request_masterchannel(1).
+
+Below is example pseudo-code on how a 'privileged' application
+can hook up n_tracerouter and n_tracesink to any tty on
+a system.  'Privileged' means the application has enough
+privileges to successfully manipulate the ldisc drivers
+but is not just blindly executing as 'root'. Keep in mind
+the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter
+and n_tracesink line discpline drivers but is a generic
+operation for a program to use a line discpline driver
+on a tty port other than the default n_tty::

-III/ Time of day service
+
+3. Time of day service
+======================
 
 The part of the driver gives access to the time of day service of EFI.
 Two ioctl()s, compatible with the legacy RTC calls:
 
-        Read the CMOS clock: ioctl(d, RTC_RD_TIME, &rtc);
+        Read the CMOS clock::
+
+                ioctl(d, RTC_RD_TIME, &rtc);
+
+        Write the CMOS clock::
 
-        Write the CMOS clock: ioctl(d, RTC_SET_TIME, &rtc);
+                ioctl(d, RTC_SET_TIME, &rtc);
 
 The rtc is a pointer to a data structure defined in rtc.h which is close
-to a struct tm:
-
-struct rtc_time {
-        int tm_sec;
-        int tm_min;
-        int tm_hour;
-        int tm_mday;
-        int tm_mon;
-        int tm_year;
-        int tm_wday;
-        int tm_yday;
-        int tm_isdst;
-};
+to a struct tm::
+
+  struct rtc_time {
+          int tm_sec;
+          int tm_min;
+          int tm_hour;
+          int tm_mday;
+          int tm_mon;
+          int tm_year;
+          int tm_wday;
+          int tm_yday;
+          int tm_isdst;
+  };
 
 The driver takes care of converting back an forth between the EFI time and
 this format.
 
 Those two ioctl()s can be exercised with the hwclock command:
 
-For reading:
-# /sbin/hwclock --show
-Mon Mar  6 15:32:32 2000  -0.910248 seconds
+For reading::

+For setting::

+        # /sbin/hwclock --systohc
 
 Root privileges are required to be able to set the time of day.
 
-IV/ Wakeup Alarm service
+4. Wakeup Alarm service
+=======================
 
 EFI provides an API by which one can program when a machine should wakeup,
 i.e. reboot. This is very different from the alarm provided by the legacy
 RTC which is some kind of interval timer alarm. For this reason we don't use
 the same ioctl()s to get access to the service. Instead we have

+
+ 2. # make world
+
+ 3. # make install-tools
+
+ 4. copy kernels and xen::
+
+        # cp xen/xen.gz /boot/efi/efi/redhat/
+        # cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
+        /boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
+
+ 5. make initrd for Dom0/DomU::
+
+        # make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
+          O=$(pwd)/build-linux-2.6.18-xen_ia64

+          --builtin ehci-hcd
+
+Making a disk image for guest OS
+================================
+
+ 1. make file::
+
+      # dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
+      # mke2fs -F -j /root/rhel5.img

+      # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
+      # mkdir /mnt/{root,proc,sys,home,tmp}
+
+      Note: You may miss some device files. If so, please create them
+      with mknod. Or you can use tar instead of cp.
+
+ 2. modify DomU's fstab::
+
+      # vi /mnt/etc/fstab
+         /dev/xvda1  /            ext3    defaults        1 1
+         none        /dev/pts     devpts  gid=5,mode=620  0 0

+         none        /sys         sysfs   defaults        0 0
+
+ 3. modify inittab
+
+    set runlevel to 3 to avoid X trying to start::
+
+      # vi /mnt/etc/inittab
+         id:3:initdefault:
+
+    Start a getty on the hvc0 console::
+
+       X0:2345:respawn:/sbin/mingetty hvc0
+
+    tty1-6 mingetty can be commented out
+
+ 4. add hvc0 into /etc/securetty::
+
+      # vi /mnt/etc/securetty (add hvc0)
+
+ 5. umount::
+
+      # umount /mnt
+
+FYI, virt-manager can also make a disk image for guest OS.
+It's GUI tools and easy to make it.
+
+Boot Xen & Domain0
+==================
+
+ 1. replace elilo
+    elilo of RHEL5 can boot Xen and Dom0.
+    If you use old elilo (e.g RHEL4), please download from the below
+    http://elilo.sourceforge.net/cgi-bin/blosxom
+    and copy into /boot/efi/efi/redhat/::
+
+      # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
+
+ 2. modify elilo.conf (like the below)::
+
+      # vi /boot/efi/efi/redhat/elilo.conf
+      prompt
+      timeout=20
+      default=xen
+      relocatable
+
+      image=vmlinuz-2.6.18.8-xen
+             label=xen
+             vmm=xen.gz
+             initrd=initrd-2.6.18.8-xen.img
+             read-only
+             append=" -- rhgb root=/dev/sda2"
+
+The append options before "--" are for xen hypervisor,
+the options after "--" are for dom0.
+
+FYI, your machine may need console options like
+"com1=19200,8n1 console=vga,com1". For example,
+append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
+console=ttyS0 root=/dev/sda2"
+
+Getting and Building domU with pv_ops
+=====================================
+
+ 1. get pv_ops tree::
+
+      # git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
+
+ 2. git branch (if necessary)::
+
+      # cd linux-2.6-xen-ia64/
+      # git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
+
+   Note:
+     The current branch is xen-ia64-domu-minimal-2008may19.
+     But you would find the new branch. You can see with
+     "git branch -r" to get the branch lists.
+
+       http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
+
+     is also available.
+
+     The tree is based on
+
+      git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
+
+ 3. copy .config for pv_ops of domU::
+
+      # cp arch/ia64/configs/xen_domu_wip_defconfig .config
+
+ 4. make kernel with pv_ops::
+
+      # make oldconfig
+      # make
+
+ 5. install the kernel and initrd::
+
+      # cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
+      # make modules_install
+      # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
+        2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
+        --builtin mptbase --builtin mptscsih --builtin uhci-hcd \
+        --builtin ohci-hcd --builtin ehci-hcd
+
+Boot DomainU with pv_ops
+========================
+
+ 1. make config of DomU::
+
+     # vi /etc/xen/rhel5
+       kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
+       ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
+       vcpus = 1
+       memory = 512
+       name = "rhel5"
+       disk = [ 'file:/root/rhel5.img,xvda1,w' ]
+       root = "/dev/xvda1 ro"
+       extra= "rhgb console=hvc0"
+
+ 2. After boot xen and dom0, start xend::
+
+        # /etc/init.d/xend start
+
+   ( In the debugging case, `# XEND_DEBUG=1 xend trace_start` )
+
+ 3. start domU::
+
+        # xm create -c rhel5

+November, 2004
+
+This document attempts to describe the ioctl(2) calls supported by
+the CDROM layer.  These are by-and-large implemented (as of Linux 2.6)
+in drivers/cdrom/cdrom.c and drivers/block/scsi_ioctl.c
+
+ioctl values are listed in <linux/cdrom.h>.  As of this writing, they

+
+
+                Ok, this is where problems start.  The current interface for
+                the CDROM_DISC_STATUS ioctl is flawed.  It makes the false
+                assumption that CDs are all CDS_DATA_1 or all CDS_AUDIO, etc.
+                Unfortunately, while this is often the case, it is also
+                very common for CDs to have some tracks with data, and some
+                tracks with audio.      Just because I feel like it, I declare
+                the following to be the best way to cope.  If the CD has
+                ANY data tracks on it, it will be returned as a data CD.
+                If it has any XA tracks, I will return it as that.      Now I
+                could simplify this interface by combining these returns with
+                the above, but this more clearly demonstrates the problem
+                with the current interface.  Too bad this wasn't designed
+                to use bitmasks...             -Erik
+
+                Well, now we have the option CDS_MIXED: a mixed-type CD.
+                User level programmers might feel the ioctl is not very
+                useful.

-
-            Ok, this is where problems start.  The current interface for
-            the CDROM_DISC_STATUS ioctl is flawed.  It makes the false
-            assumption that CDs are all CDS_DATA_1 or all CDS_AUDIO, etc.
-            Unfortunately, while this is often the case, it is also
-            very common for CDs to have some tracks with data, and some
-            tracks with audio.  Just because I feel like it, I declare
-            the following to be the best way to cope.  If the CD has
-            ANY data tracks on it, it will be returned as a data CD.
-            If it has any XA tracks, I will return it as that.  Now I
-            could simplify this interface by combining these returns with
-            the above, but this more clearly demonstrates the problem
-            with the current interface.  Too bad this wasn't designed
-            to use bitmasks...         -Erik
-
-            Well, now we have the option CDS_MIXED: a mixed-type CD.
-            User level programmers might feel the ioctl is not very
-            useful.

-        notes:
-          As of 2.6.8.1, the lock flag is a global lock, meaning that
-          all CD drives will be locked or unlocked together.  This is
-          probably a bug.
-

+Ioctl Numbers
+=============
+
+19 October 1999
+
+Michael Elizabeth Chastain
+<mec@shout.net>
+
+If you are adding new ioctl's to the kernel, you should use the _IO
+macros defined in <linux/ioctl.h>:
+
+    ====== == ============================================
+    _IO    an ioctl with no parameters
+    _IOW   an ioctl with write parameters (copy_from_user)
+    _IOR   an ioctl with read parameters  (copy_to_user)
+    _IOWR  an ioctl with both write and read parameters.
+    ====== == ============================================
+
+'Write' and 'read' are from the user's point of view, just like the
+system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
+be _IOW, although the kernel would actually read data from user space;
+a GET_FOO ioctl would be _IOR, although the kernel would actually write
+data to user space.
+
+The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
+or number from the table below.  Because of the large number of drivers,
+many drivers share a partial letter with other drivers.
+
+If you are writing a driver for a new device and need a letter, pick an
+unused block with enough room for expansion: 32 to 256 ioctl commands.
+You can register the block by patching this file and submitting the
+patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
+I'll register one for you.
+
+The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
+to distinguish ioctls from each other.  The third argument to _IOW,
+_IOR, or _IOWR is the type of the data going into the kernel or coming
+out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
+sizeof(arg) as the third argument as this results in your ioctl thinking
+it passes an argument of type size_t.
+
+Some devices use their major number as the identifier; this is OK, as
+long as it is unique.  Some devices are irregular and don't follow any
+convention at all.
+
+Following this convention is good because:
+
+(1) Keeping the ioctl's globally unique helps error checking:
+    if a program calls an ioctl on the wrong device, it will get an
+    error rather than some unexpected behaviour.
+
+(2) The 'strace' build procedure automatically finds ioctl numbers
+    defined with _IO, _IOW, _IOR, or _IOWR.
+
+(3) 'strace' can decode numbers back into useful names when the
+    numbers are unique.
+
+(4) People looking for ioctls can grep for them more easily when
+    this convention is used to define the ioctl numbers.
+
+(5) When following the convention, the driver code can use generic
+    code to copy the parameters between user and kernel space.
+
+This table lists ioctls visible from user land for Linux/x86.  It contains
+most drivers up to 2.6.31, but I know I am missing some.  There has been
+no attempt to list non-X86 architectures or ioctls from drivers/staging/.

-Ioctl Numbers
-19 October 1999
-Michael Elizabeth Chastain
-<mec@shout.net>
-
-If you are adding new ioctl's to the kernel, you should use the _IO
-macros defined in <linux/ioctl.h>:
-
-    _IO    an ioctl with no parameters
-    _IOW   an ioctl with write parameters (copy_from_user)
-    _IOR   an ioctl with read parameters  (copy_to_user)
-    _IOWR  an ioctl with both write and read parameters.
-
-'Write' and 'read' are from the user's point of view, just like the
-system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
-be _IOW, although the kernel would actually read data from user space;
-a GET_FOO ioctl would be _IOR, although the kernel would actually write
-data to user space.
-
-The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
-or number from the table below.  Because of the large number of drivers,
-many drivers share a partial letter with other drivers.
-
-If you are writing a driver for a new device and need a letter, pick an
-unused block with enough room for expansion: 32 to 256 ioctl commands.
-You can register the block by patching this file and submitting the
-patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
-I'll register one for you.
-
-The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
-to distinguish ioctls from each other.  The third argument to _IOW,
-_IOR, or _IOWR is the type of the data going into the kernel or coming
-out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
-sizeof(arg) as the third argument as this results in your ioctl thinking
-it passes an argument of type size_t.
-
-Some devices use their major number as the identifier; this is OK, as
-long as it is unique.  Some devices are irregular and don't follow any
-convention at all.
-
-Following this convention is good because:
-
-(1) Keeping the ioctl's globally unique helps error checking:
-    if a program calls an ioctl on the wrong device, it will get an
-    error rather than some unexpected behaviour.
-
-(2) The 'strace' build procedure automatically finds ioctl numbers
-    defined with _IO, _IOW, _IOR, or _IOWR.
-
-(3) 'strace' can decode numbers back into useful names when the
-    numbers are unique.
-
-(4) People looking for ioctls can grep for them more easily when
-    this convention is used to define the ioctl numbers.
-
-(5) When following the convention, the driver code can use generic
-    code to copy the parameters between user and kernel space.
-
-This table lists ioctls visible from user land for Linux/x86.  It contains
-most drivers up to 2.6.31, but I know I am missing some.  There has been
-no attempt to list non-X86 architectures or ioctls from drivers/staging/.

+Lock Statistics
+===============
+
+What
+====
+
+As the name suggests, it provides statistics on locks.
+
+
+Why
+===
+
+Because things like lock contention can severely impact performance.
+
+How
+===
+
+Lockdep already has hooks in the lock functions and maps lock instances to
+lock classes. We build on that (see Documentation/locking/lockdep-design.rst).
+The graph below shows the relation between the lock functions and the various
+hooks therein::
+
+        __acquire
+            |
+           lock _____
+            |        \
+            |    __contended
+            |         |

+
+  lock, unlock  - the regular lock functions
+  __*           - the hooks
+  <>            - states
+
+With these hooks we provide the following statistics:
+
+ con-bounces
+        - number of lock contention that involved x-cpu data
+ contentions
+        - number of lock acquisitions that had to wait
+ wait time
+     min
+        - shortest (non-0) time we ever had to wait for a lock
+     max
+        - longest time we ever had to wait for a lock
+     total
+        - total time we spend waiting on this lock
+     avg
+        - average time spent waiting on this lock
+ acq-bounces

+     total
+        - total time this lock was held
+     avg
+        - average time this lock was held
+
+These numbers are gathered per lock class, per read/write state (when
+applicable).
+
+It also tracks 4 contention points per class. A contention point is a call site
+that had to wait on lock acquisition.

+This excerpt shows the first two lock class statistics. Line 01 shows the
+output version - each time the format changes this will be updated. Line 02-04
+show the header with column descriptions. Lines 05-18 and 20-31 show the actual
+statistics. These statistics come in two parts; the actual stats separated by a
+short separator (line 08, 13) from the contention points.
+
+Lines 09-12 show the first 4 recorded contention points (the code
+which tries to get the lock) and lines 14-17 show the first 4 recorded
+contended points (the lock holder). It is possible that the max
+con-bounces point is missing in the statistics.
+
+The first lock (05-18) is a read/write lock, and shows two lines above the
+short separator. The contention points don't match the column descriptors,
+they have two: contentions and [<IP>] symbol. The second set of contention
+points are the points we're contending with.
+
+The integer part of the time values is in us.
+
+Dealing with nested locks, subclasses may appear::

-LOCK STATISTICS
-
-- WHAT
-
-As the name suggests, it provides statistics on locks.
-
-- WHY
-
-Because things like lock contention can severely impact performance.
-
-- HOW
-
-Lockdep already has hooks in the lock functions and maps lock instances to
-lock classes. We build on that (see Documentation/locking/lockdep-design.txt).
-The graph below shows the relation between the lock functions and the various
-hooks therein.
-
-        __acquire
-            |
-           lock _____
-            |        \
-            |    __contended
-            |         |
-            |       <wait>
-            | _______/
-            |/
-            |
-       __acquired
-            |
-            .
-          <hold>
-            .
-            |
-       __release
-            |
-         unlock
-
-lock, unlock    - the regular lock functions
-__*             - the hooks
-<>              - states
-
-With these hooks we provide the following statistics:
-
- con-bounces       - number of lock contention that involved x-cpu data
- contentions       - number of lock acquisitions that had to wait
- wait time min     - shortest (non-0) time we ever had to wait for a lock
-           max     - longest time we ever had to wait for a lock
-           total   - total time we spend waiting on this lock
-           avg     - average time spent waiting on this lock
- acq-bounces       - number of lock acquisitions that involved x-cpu data
- acquisitions      - number of times we took the lock
- hold time min     - shortest (non-0) time we ever held the lock
-           max     - longest time we ever held the lock
-           total   - total time this lock was held
-           avg     - average time this lock was held
-
-These numbers are gathered per lock class, per read/write state (when
-applicable).
-
-It also tracks 4 contention points per class. A contention point is a call site
-that had to wait on lock acquisition.
-
- - CONFIGURATION
-
-Lock statistics are enabled via CONFIG_LOCK_STAT.
-
- - USAGE
-
-Enable collection of statistics:
-
-# echo 1 >/proc/sys/kernel/lock_stat
-
-Disable collection of statistics:
-
-# echo 0 >/proc/sys/kernel/lock_stat
-
-Look at the current lock statistics:
-
-( line numbers not part of actual output, done for clarity in the explanation
-  below )
-
-# less /proc/lock_stat

-This excerpt shows the first two lock class statistics. Line 01 shows the
-output version - each time the format changes this will be updated. Line 02-04
-show the header with column descriptions. Lines 05-18 and 20-31 show the actual
-statistics. These statistics come in two parts; the actual stats separated by a
-short separator (line 08, 13) from the contention points.
-
-Lines 09-12 show the first 4 recorded contention points (the code
-which tries to get the lock) and lines 14-17 show the first 4 recorded
-contended points (the lock holder). It is possible that the max
-con-bounces point is missing in the statistics.
-
-The first lock (05-18) is a read/write lock, and shows two lines above the
-short separator. The contention points don't match the column descriptors,
-they have two: contentions and [<IP>] symbol. The second set of contention
-points are the points we're contending with.

-The integer part of the time values is in us.

-The Intel MID PTI project is HW implemented in Intel Atom
-system-on-a-chip designs based on the Parallel Trace
-Interface for MIPI P1149.7 cJTAG standard.  The kernel solution
-for this platform involves the following files:
-
-./include/linux/pti.h
-./drivers/.../n_tracesink.h
-./drivers/.../n_tracerouter.c
-./drivers/.../n_tracesink.c
-./drivers/.../pti.c
-
-pti.c is the driver that enables various debugging features
-popular on platforms from certain mobile manufacturers.
-n_tracerouter.c and n_tracesink.c allow extra system information to
-be collected and routed to the pti driver, such as trace
-debugging data from a modem.  Although n_tracerouter
-and n_tracesink are a part of the complete PTI solution,
-these two line disciplines can work separately from
-pti.c and route any data stream from one /dev/tty node
-to another /dev/tty node via kernel-space.  This provides
-a stable, reliable connection that will not break unless
-the user-space application shuts down (plus avoids
-kernel->user->kernel context switch overheads of routing
-data).
-
-An example debugging usage for this driver system:
-   *Hook /dev/ttyPTI0 to syslogd.  Opening this port will also start
-    a console device to further capture debugging messages to PTI.
-   *Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.
-    This is where n_tracerouter and n_tracesink are used.
-   *Hook /dev/pti to a user-level debugging application for writing
-    to PTI HW.
-   *Use mipi_* Kernel Driver API in other device drivers for
-    debugging to PTI by first requesting a PTI write address via
-    mipi_request_masterchannel(1).
-
-Below is example pseudo-code on how a 'privileged' application
-can hook up n_tracerouter and n_tracesink to any tty on
-a system.  'Privileged' means the application has enough
-privileges to successfully manipulate the ldisc drivers
-but is not just blindly executing as 'root'. Keep in mind
-the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter
-and n_tracesink line discpline drivers but is a generic
-operation for a program to use a line discpline driver
-on a tty port other than the default n_tty.

-MMUv3 initialization sequence.
-
-The code in the initialize_mmu macro sets up MMUv3 memory mapping
-identically to MMUv2 fixed memory mapping. Depending on
-CONFIG_INITIALIZE_XTENSA_MMU_INSIDE_VMLINUX symbol this code is
-located in addresses it was linked for (symbol undefined), or not
-(symbol defined), so it needs to be position-independent.
-
-The code has the following assumptions:
-  This code fragment is run only on an MMU v3.
-  TLBs are in their reset state.
-  ITLBCFG and DTLBCFG are zero (reset state).
-  RASID is 0x04030201 (reset state).
-  PS.RING is zero (reset state).
-  LITBASE is zero (reset state, PC-relative literals); required to be PIC.
-
-TLB setup proceeds along the following steps.
-
-  Legend:
-    VA = virtual address (two upper nibbles of it);
-    PA = physical address (two upper nibbles of it);
-    pc = physical range that contains this code;
-
-After step 2, we jump to virtual address in the range 0x40000000..0x5fffffff
-or 0x00000000..0x1fffffff, depending on whether the kernel was loaded below
-0x40000000 or above. That address corresponds to next instruction to execute
-in this code. After step 4, we jump to intended (linked) address of this code.
-The scheme below assumes that the kernel is loaded below 0x40000000.

-The default location of IO peripherals is above 0xf0000000. This may be changed
-using a "ranges" property in a device tree simple-bus node. See the Devicetree
-Specification, section 4.5 for details on the syntax and semantics of
-simple-bus nodes. The following limitations apply:
-
-1. Only top level simple-bus nodes are considered
-
-2. Only one (first) simple-bus node is considered
-
-3. Empty "ranges" properties are not supported
-
-4. Only the first triplet in the "ranges" property is considered
-
-5. The parent-bus-address value is rounded down to the nearest 256MB boundary
-
-6. The IO area covers the entire 256MB segment of parent-bus-address; the
-   "ranges" triplet length field is ignored
