+ORANGEFS
+========
+
+OrangeFS is an LGPL userspace scale-out parallel storage system. It is ideal
+for large storage problems faced by HPC, BigData, Streaming Video,
+Genomics, Bioinformatics.
+
+Orangefs, originally called PVFS, was first developed in 1993 by
+Walt Ligon and Eric Blumer as a parallel file system for Parallel
+Virtual Machine (PVM) as part of a NASA grant to study the I/O patterns
+of parallel programs.
+
+Orangefs features include:
+
+ * Distributes file data among multiple file servers
+ * Supports simultaneous access by multiple clients
+ * Stores file data and metadata on servers using local file system
+ and access methods
+ * Userspace implementation is easy to install and maintain
+ * Direct MPI support
+ * Stateless
+
+
+MAILING LIST

+
+
+DOCUMENTATION

+
+http://www.orangefs.org/documentation/
+
+
+USERSPACE FILESYSTEM SOURCE
+===========================
+
+http://www.orangefs.org/download
+
+Orangefs versions prior to 2.9.3 would not be compatible with the
+upstream version of the kernel client.
+
+
+BUILDING THE USERSPACE FILESYSTEM ON A SINGLE SERVER
+====================================================
+
+When Orangefs is upstream, "--with-kernel" shouldn't be needed, but
+until then the path to where the kernel with the Orangefs kernel client
+patch was built is needed to ensure that pvfs2-client-core (the bridge
+between kernel space and user space) will build properly. You can omit
+--prefix if you don't care that things are sprinkled around in
+/usr/local.
+
+./configure --prefix=/opt/ofs --with-kernel=/path/to/orangefs/kernel
+
+make
+
+make install
+
+Create an orangefs config file:
+/opt/ofs/bin/pvfs2-genconfig /etc/pvfs2.conf
+
+ for "Enter hostnames", use the hostname, don't let it default to
+ localhost.
+
+create a pvfs2tab file in /etc:
+cat /etc/pvfs2tab
+tcp://myhostname:3334/orangefs /mymountpoint pvfs2 defaults,noauto 0 0
+
+create the mount point you specified in the tab file if needed:
+mkdir /mymountpoint
+
+bootstrap the server:
+/opt/ofs/sbin/pvfs2-server /etc/pvfs2.conf -f
+
+start the server:
+/opt/osf/sbin/pvfs2-server /etc/pvfs2.conf
+
+Now the server is running. At this point you might like to
+prove things are working with:
+
+/opt/osf/bin/pvfs2-ls /mymountpoint
+
+You might not want to enforce selinux, it doesn't seem to matter by
+linux 3.11...
+
+If stuff seems to be working, turn on the client core:
+/opt/osf/sbin/pvfs2-client -p /opt/osf/sbin/pvfs2-client-core
+
+Mount your filesystem.
+mount -t pvfs2 tcp://myhostname:3334/orangefs /mymountpoint
+
+
+OPTIONS
+=======
+
+The following mount options are accepted:
+
+ acl
+ Allow the use of Access Control Lists on files and directories.
+
+ intr
+ Some operations between the kernel client and the user space
+ filesystem can be interruptible, such as changes in debug levels
+ and the setting of tunable parameters.
+
+ local_lock
+ Enable posix locking from the perspective of "this" kernel. The
+ default file_operations lock action is to return ENOSYS. Posix
+ locking kicks in if the filesystem is mounted with -o local_lock.
+ Distributed locking is being worked on for the future.
+
+
+DEBUGGING
+=========
+
+If you want the debug (GOSSIP) statements in a particular
+source file (inode.c for example) go to syslog:
+
+ echo inode > /sys/kernel/debug/orangefs/kernel-debug
+
+No debugging (the default):
+
+ echo none > /sys/kernel/debug/orangefs/kernel-debug
+
+Debugging from several source files:
+
+ echo inode,dir > /sys/kernel/debug/orangefs/kernel-debug
+
+All debugging:
+
+ echo all > /sys/kernel/debug/orangefs/kernel-debug
+
+Get a list of all debugging keywords:
+
+ cat /sys/kernel/debug/orangefs/debug-help
+
+
+PROTOCOL BETWEEN KERNEL MODULE AND USERSPACE
+============================================
+
+Orangefs is a user space filesystem and an associated kernel module.
+We'll just refer to the user space part of Orangefs as "userspace"
+from here on out. Orangefs descends from PVFS, and userspace code
+still uses PVFS for function and variable names. Userspace typedefs
+many of the important structures. Function and variable names in
+the kernel module have been transitioned to "orangefs", and The Linux
+Coding Style avoids typedefs, so kernel module structures that
+correspond to userspace structures are not typedefed.
+
+The kernel module implements a pseudo device that userspace
+can read from and write to. Userspace can also manipulate the
+kernel module through the pseudo device with ioctl.
+
+THE BUFMAP:
+
+At startup userspace allocates two page-size-aligned (posix_memalign)
+mlocked memory buffers, one is used for IO and one is used for readdir
+operations. The IO buffer is 41943040 bytes and the readdir buffer is
+4194304 bytes. Each buffer contains logical chunks, or partitions, and
+a pointer to each buffer is added to its own PVFS_dev_map_desc structure
+which also describes its total size, as well as the size and number of
+the partitions.
+
+A pointer to the IO buffer's PVFS_dev_map_desc structure is sent to a
+mapping routine in the kernel module with an ioctl. The structure is
+copied from user space to kernel space with copy_from_user and is used
+to initialize the kernel module's "bufmap" (struct orangefs_bufmap), which
+then contains:
+
+ * refcnt - a reference counter
+ * desc_size - PVFS2_BUFMAP_DEFAULT_DESC_SIZE (4194304) - the IO buffer's
+ partition size, which represents the filesystem's block size and
+ is used for s_blocksize in super blocks.
+ * desc_count - PVFS2_BUFMAP_DEFAULT_DESC_COUNT (10) - the number of
+ partitions in the IO buffer.
+ * desc_shift - log2(desc_size), used for s_blocksize_bits in super blocks.
+ * total_size - the total size of the IO buffer.
+ * page_count - the number of 4096 byte pages in the IO buffer.
+ * page_array - a pointer to page_count * (sizeof(struct page*)) bytes
+ of kcalloced memory. This memory is used as an array of pointers
+ to each of the pages in the IO buffer through a call to get_user_pages.
+ * desc_array - a pointer to desc_count * (sizeof(struct orangefs_bufmap_desc))
+ bytes of kcalloced memory. This memory is further intialized:
+
+ user_desc is the kernel's copy of the IO buffer's ORANGEFS_dev_map_desc
+ structure. user_desc->ptr points to the IO buffer.
+
+ pages_per_desc = bufmap->desc_size / PAGE_SIZE
+ offset = 0
+
+ bufmap->desc_array[0].page_array = &bufmap->page_array[offset]
+ bufmap->desc_array[0].array_count = pages_per_desc = 1024
+ bufmap->desc_array[0].uaddr = (user_desc->ptr) + (0 * 1024 * 4096)
+ offset += 1024
+ .
+ .
+ .
+ bufmap->desc_array[9].page_array = &bufmap->page_array[offset]
+ bufmap->desc_array[9].array_count = pages_per_desc = 1024
+ bufmap->desc_array[9].uaddr = (user_desc->ptr) +
+ (9 * 1024 * 4096)
+ offset += 1024
+
+ * buffer_index_array - a desc_count sized array of ints, used to
+ indicate which of the IO buffer's partitions are available to use.
+ * buffer_index_lock - a spinlock to protect buffer_index_array during update.
+ * readdir_index_array - a five (ORANGEFS_READDIR_DEFAULT_DESC_COUNT) element
+ int array used to indicate which of the readdir buffer's partitions are
+ available to use.
+ * readdir_index_lock - a spinlock to protect readdir_index_array during
+ update.
+
+OPERATIONS:
+
+The kernel module builds an "op" (struct orangefs_kernel_op_s) when it
+needs to communicate with userspace. Part of the op contains the "upcall"
+which expresses the request to userspace. Part of the op eventually
+contains the "downcall" which expresses the results of the request.
+
+The slab allocator is used to keep a cache of op structures handy.
+
+The life cycle of a typical op goes like this:
+
+ - obtain and initialize an op structure from the op_cache.
+
+ - queue the op to the pvfs device so that its upcall data can be
+ read by userspace.
+
+ - wait for userspace to write downcall data back to the pvfs device.
+
+ - consume the downcall and return the op struct to the op_cache.
+
+Some ops are atypical with respect to their payloads: readdir and io ops.
+
+ - readdir ops use the smaller of the two pre-allocated pre-partitioned
+ memory buffers. The readdir buffer is only available to userspace.
+ The kernel module obtains an index to a free partition before launching
+ a readdir op. Userspace deposits the results into the indexed partition
+ and then writes them to back to the pvfs device.
+
+ - io (read and write) ops use the larger of the two pre-allocated
+ pre-partitioned memory buffers. The IO buffer is accessible from
+ both userspace and the kernel module. The kernel module obtains an
+ index to a free partition before launching an io op. The kernel module
+ deposits write data into the indexed partition, to be consumed
+ directly by userspace. Userspace deposits the results of read
+ requests into the indexed partition, to be consumed directly
+ by the kernel module.
+
+Responses to kernel requests are all packaged in pvfs2_downcall_t
+structs. Besides a few other members, pvfs2_downcall_t contains a
+union of structs, each of which is associated with a particular
+response type.
+
+The several members outside of the union are:
+ - int32_t type - type of operation.
+ - int32_t status - return code for the operation.
+ - int64_t trailer_size - 0 unless readdir operation.
+ - char *trailer_buf - initialized to NULL, used during readdir operations.
+
+The appropriate member inside the union is filled out for any
+particular response.

+ - a pointer to the prepared response to the request from the
+ kernel (struct pvfs2_downcall_t).
+ - and also, in the case of a readdir request, a pointer to a
+ buffer containing descriptors for the objects in the target
+ directory.
+... is sent to the function (PINT_dev_write_list) which performs
+the writev.
+
+PINT_dev_write_list has a local iovec array: struct iovec io_array[10];
+
+The first four elements of io_array are initialized like this for all
+responses:
+
+ io_array[0].iov_base = address of local variable "proto_ver" (int32_t)
+ io_array[0].iov_len = sizeof(int32_t)
+
+ io_array[1].iov_base = address of global variable "pdev_magic" (int32_t)
+ io_array[1].iov_len = sizeof(int32_t)
+
+ io_array[2].iov_base = address of parameter "tag" (PVFS_id_gen_t)
+ io_array[2].iov_len = sizeof(int64_t)
+
+ io_array[3].iov_base = address of out_downcall member (pvfs2_downcall_t)
+ of global variable vfs_request (vfs_request_t)
+ io_array[3].iov_len = sizeof(pvfs2_downcall_t)
+
+Readdir responses initialize the fifth element io_array like this:
+
+ io_array[4].iov_base = contents of member trailer_buf (char *)
+ from out_downcall member of global variable
+ vfs_request
+ io_array[4].iov_len = contents of member trailer_size (PVFS_size)

+Kernel driver ltc2990
+=====================
+
+Supported chips:
+ * Linear Technology LTC2990
+ Prefix: 'ltc2990'
+ Addresses scanned: -
+ Datasheet: http://www.linear.com/product/ltc2990
+
+Author: Mike Looijmans <mike.looijmans@topic.nl>
+
+
+Description
+-----------
+
+LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
+The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
+can be combined to measure a differential voltage, which is typically used to
+measure current through a series resistor, or a temperature.
+
+This driver currently uses the 2x differential mode only. In order to support
+other modes, the driver will need to be expanded.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+
+Sysfs attributes
+----------------
+
+The "curr*_input" measurements actually report the voltage drop across the
+input pins in microvolts. This is equivalent to the current through a 1mOhm
+sense resistor. Divide the reported value by the actual sense resistor value
+in mOhm to get the actual value.
+
+in0_input Voltage at Vcc pin in millivolt (range 2.5V to 5V)
+temp1_input Internal chip temperature in millidegrees Celcius
+curr1_input Current in mA across v1-v2 assuming a 1mOhm sense resistor.
+curr2_input Current in mA across v3-v4 assuming a 1mOhm sense resistor.

+ workqueue.debug_force_rr_cpu
+ Workqueue used to implicitly guarantee that work
+ items queued without explicit CPU specified are put
+ on the local CPU. This guarantee is no longer true
+ and while local CPU is still preferred work items
+ may be put on foreign CPUs. This debug option
+ forces round-robin CPU selection to flush out
+ usages which depend on the now broken guarantee.
+ When enabled, memory and cache locality will be
+ impacted.

- * from Cortex-A15 core.
+ * This file provides desired ordering for Exynos5422: CPU[0123] being the A7.
*
- * EXYNOS5422 based board files can include this file to provide cpu ordering
- * which could boot a cortex-a7 from cpu0.
+ * The Exynos5420, 5422 and 5800 actually share the same CPU configuration
+ * but particular boards choose different booting order.
+ *
+ * Exynos5420 and Exynos5800 always boot from Cortex-A15. On Exynos5422
+ * booting cluster (big or LITTLE) is chosen by IROM code by reading

- If this is set, kernel text and rodata will be made read-only. This

- space while gaining the read-only protections.
+ If this is set, rodata will be made explicitly non-executable. This

+ additional section-aligned split of rodata from kernel text so it
+ can be made explicitly non-executable. This padding may waste memory

- * For DAX page faults, we are preparing to never see unwritten extents here,
- * nor should we ever extend the inode size. Hence we will soon have nothing to
- * do here for this case, ensuring we don't have to provide an IO completion
