of the API (and actual examples) see

This API is split into two pieces. Part I describes the API and the
corresponding pci_ API. Part II describes the extensions to the API
for supporting non-consistent memory machines. Unless you know that
your driver absolutely has to support non-consistent platforms (this
is usually only legacy platforms) you should only use the API
described in part I.

By default, the kernel assumes that your device can address the full

And for a device with limitations, as discussed in the previous
paragraph, it needs to be decreased.
pci_alloc_consistent() by default will return 32-bit DMA addresses.
PCI-X specification requires PCI-X devices to support 64-bit
addressing (DAC) for all transactions. And at least one platform (SGI
SN2) requires 64-bit consistent allocations to operate correctly when
the IO bus is in PCI-X mode. Therefore, like with pci_set_dma_mask(),
it's good practice to call pci_set_consistent_dma_mask() to set the
appropriate mask even if your device only supports 32-bit DMA
(default) and especially if it's a PCI-X device.
Special note about PCI: PCI-X specification requires PCI-X devices to
support 64-bit addressing (DAC) for all transactions. And at least
one platform (SGI SN2) requires 64-bit consistent allocations to
operate correctly when the IO bus is in PCI-X mode.

Another common scenario is a 64-bit capable device. The approach
here is to try for 64-bit DAC addressing, but back down to a
32-bit mask should that fail. The PCI platform code may fail the
64-bit mask not because the platform is not capable of 64-bit
addressing. Rather, it may fail in this case simply because
32-bit SAC addressing is done more efficiently than DAC addressing.

Samsung ARM Linux Overview
==========================
Introduction
------------
The Samsung range of ARM SoCs spans many similar devices, from the initial
ARM9 through to the newest ARM cores. This document shows an overview of
the current kernel support, how to use it and where to find the code
that supports this.
The currently supported SoCs are:
- S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
- S3C64XX: S3C6400 and S3C6410
- S5PC6440
S5PC100 and S5PC110 support is currently being merged
S3C24XX Systems
---------------
There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
deals with the architecture and drivers specific to these devices.
See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
on the implementation details and specific support.
Configuration
-------------
A number of configurations are supplied, as there is no current way of
unifying all the SoCs into one kernel.
s5p6440_defconfig - S5P6440 specific default configuration
s5pc100_defconfig - S5PC100 specific default configuration
Layout
------
The directory layout is currently being restructured, and consists of
several platform directories and then the machine specific directories
of the CPUs being built for.
plat-samsung provides the base for all the implementations, and is the
last in the line of include directories that are processed for the build
specific information. It contains the base clock, GPIO and device definitions
to get the system running.
plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently
involved in other builds this will be phased out once the relevant code is
moved elsewhere.
plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs.
plat-s5p is for s5p specific builds, more to be added.

2.4 Notification API
--------------------
There is mechanism which allows to get notifications about changing
status of a cgroup.
To register new notification handler you need:
- create a file descriptor for event notification using eventfd(2);
- open a control file to be monitored (e.g. memory.usage_in_bytes);
- write "<event_fd> <control_fd> <args>" to cgroup.event_control.
Interpretation of args is defined by control file implementation;
eventfd will be woken up by control file implementation or when the
cgroup is removed.
To unregister notification handler just close eventfd.

8. Move charges at task migration
Users can move charges associated with a task along with task migration, that
is, uncharge task's pages from the old cgroup and charge them to the new cgroup.
This feature is not supported in !CONFIG_MMU environments because of lack of
page tables.
8.1 Interface
This feature is disabled by default. It can be enabled(and disabled again) by
writing to memory.move_charge_at_immigrate of the destination cgroup.
If you want to enable it:
# echo (some positive value) > memory.move_charge_at_immigrate
Note: Each bits of move_charge_at_immigrate has its own meaning about what type
of charges should be moved. See 8.2 for details.
Note: Charges are moved only when you move mm->owner, IOW, a leader of a thread
group.
Note: If we cannot find enough space for the task in the destination cgroup, we
try to make space by reclaiming memory. Task migration may fail if we
cannot make enough space.
Note: It can take several seconds if you move charges in giga bytes order.
And if you want disable it again:
# echo 0 > memory.move_charge_at_immigrate
8.2 Type of charges which can be move
Each bits of move_charge_at_immigrate has its own meaning about what type of
charges should be moved.
bit | what type of charges would be moved ?
-----+------------------------------------------------------------------------
0 | A charge of an anonymous page(or swap of it) used by the target task.
| Those pages and swaps must be used only by the target task. You must
| enable Swap Extension(see 2.4) to enable move of swap charges.
Note: Those pages and swaps must be charged to the old cgroup.
Note: More type of pages(e.g. file cache, shmem,) will be supported by other
bits in future.
8.3 TODO
- Add support for other types of pages(e.g. file cache, shmem, etc.).
- Implement madvise(2) to let users decide the vma to be moved or not to be
moved.
- All of moving charge operations are done under cgroup_mutex. It's not good
behavior to hold the mutex too long, so we may need some trick.
9. Memory thresholds
Memory controler implements memory thresholds using cgroups notification
API (see cgroups.txt). It allows to register multiple memory and memsw
thresholds and gets notifications when it crosses.
To register a threshold application need:
- create an eventfd using eventfd(2);
- open memory.usage_in_bytes or memory.memsw.usage_in_bytes;
- write string like "<event_fd> <memory.usage_in_bytes> <threshold>" to
cgroup.event_control.
Application will be notified through eventfd when memory usage crosses
threshold in any direction.
It's applicable for root and non-root cgroup.
10. TODO
1. Add support for accounting huge pages (as a separate controller)
2. Make per-cgroup scanner reclaim not-shared pages first

The first problem is that Gmail converts tabs to spaces. This will
totally break your patches. To prevent this, you have to use a different
editor. There is a firefox extension called "ViewSourceWith"
(https://addons.mozilla.org/en-US/firefox/addon/394) which allows you to
edit any text box in the editor of your choice. Configure it to launch
your favorite editor. When you want to send a patch, use this technique.
Once you have crafted your messsage + patch, save and exit the editor,
which should reload the Gmail edit box. GMAIL WILL PRESERVE THE TABS.
Hoorah. Apparently you can cut-n-paste literal tabs, but Gmail will
convert those to spaces upon sending!
Gmail web client converts tabs to spaces automatically.
The second problem is that Gmail converts tabs to spaces on replies. If
you reply to a patch, don't expect to be able to apply it as a patch.
At the same time it wraps lines every 78 chars with CRLF style line breaks
although tab2space problem can be solved with external editor.
The last problem is that Gmail will base64-encode any message that has a
non-ASCII character. That includes things like European names. Be aware.

Ceph Distributed File System
============================
Ceph is a distributed network file system designed to provide good
performance, reliability, and scalability.
Basic features include:
* POSIX semantics
* Seamless scaling from 1 to many thousands of nodes
* High availability and reliability. No single points of failure.
* N-way replication of data across storage nodes
* Fast recovery from node failures
* Automatic rebalancing of data on node addition/removal
* Easy deployment: most FS components are userspace daemons
Also,
* Flexible snapshots (on any directory)
* Recursive accounting (nested files, directories, bytes)
In contrast to cluster filesystems like GFS, OCFS2, and GPFS that rely
on symmetric access by all clients to shared block devices, Ceph
separates data and metadata management into independent server
clusters, similar to Lustre. Unlike Lustre, however, metadata and
storage nodes run entirely as user space daemons. Storage nodes
utilize btrfs to store data objects, leveraging its advanced features
(checksumming, metadata replication, etc.). File data is striped
across storage nodes in large chunks to distribute workload and
facilitate high throughputs. When storage nodes fail, data is
re-replicated in a distributed fashion by the storage nodes themselves
(with some minimal coordination from a cluster monitor), making the
system extremely efficient and scalable.
Metadata servers effectively form a large, consistent, distributed
in-memory cache above the file namespace that is extremely scalable,
dynamically redistributes metadata in response to workload changes,
and can tolerate arbitrary (well, non-Byzantine) node failures. The
metadata server takes a somewhat unconventional approach to metadata
storage to significantly improve performance for common workloads. In
particular, inodes with only a single link are embedded in
directories, allowing entire directories of dentries and inodes to be
loaded into its cache with a single I/O operation. The contents of
extremely large directories can be fragmented and managed by
independent metadata servers, allowing scalable concurrent access.
The system offers automatic data rebalancing/migration when scaling
from a small cluster of just a few nodes to many hundreds, without
requiring an administrator carve the data set into static volumes or
go through the tedious process of migrating data between servers.
When the file system approaches full, new nodes can be easily added
and things will "just work."
Ceph includes flexible snapshot mechanism that allows a user to create
a snapshot on any subdirectory (and its nested contents) in the
system. Snapshot creation and deletion are as simple as 'mkdir
.snap/foo' and 'rmdir .snap/foo'.
Ceph also provides some recursive accounting on directories for nested
files and bytes. That is, a 'getfattr -d foo' on any directory in the
system will reveal the total number of nested regular files and
subdirectories, and a summation of all nested file sizes. This makes
the identification of large disk space consumers relatively quick, as
no 'du' or similar recursive scan of the file system is required.
Mount Syntax
============
The basic mount syntax is:
# mount -t ceph monip[:port][,monip2[:port]...]:/[subdir] mnt
You only need to specify a single monitor, as the client will get the
full list when it connects. (However, if the monitor you specify
happens to be down, the mount won't succeed.) The port can be left
off if the monitor is using the default. So if the monitor is at
1.2.3.4,
# mount -t ceph 1.2.3.4:/ /mnt/ceph
is sufficient. If /sbin/mount.ceph is installed, a hostname can be
used instead of an IP address.
Mount Options
=============
ip=A.B.C.D[:N]
Specify the IP and/or port the client should bind to locally.
There is normally not much reason to do this. If the IP is not
specified, the client's IP address is determined by looking at the
address it's connection to the monitor originates from.
wsize=X
Specify the maximum write size in bytes. By default there is no
maximu. Ceph will normally size writes based on the file stripe
size.
rsize=X
Specify the maximum readahead.
mount_timeout=X
Specify the timeout value for mount (in seconds), in the case
of a non-responsive Ceph file system. The default is 30
seconds.
rbytes
When stat() is called on a directory, set st_size to 'rbytes',
the summation of file sizes over all files nested beneath that
directory. This is the default.
norbytes
When stat() is called on a directory, set st_size to the
number of entries in that directory.
nocrc
Disable CRC32C calculation for data writes. If set, the OSD
must rely on TCP's error correction to detect data corruption
in the data payload.
noasyncreaddir
Disable client's use its local cache to satisfy readdir
requests. (This does not change correctness; the client uses
cached metadata only when a lease or capability ensures it is
valid.)

direct expression of inheritance, so other techniques - such as structure
embedding - must be used.
So, for example, the UIO code has a structure that defines the memory
region associated with a uio device:
(As an aside, for those familiar with the kernel linked list implementation,
this is analogous as to how "list_head" structs are rarely useful on
their own, but are invariably found embedded in the larger objects of
interest.)
struct uio_mem {
So, for example, the UIO code in drivers/uio/uio.c has a structure that
defines the memory region associated with a uio device:
struct uio_map {
struct kobject kobj;
unsigned long addr;
unsigned long size;
int memtype;
void __iomem *internal_addr;
};
struct uio_mem *mem;
};
If you have a struct uio_mem structure, finding its embedded kobject is
If you have a struct uio_map structure, finding its embedded kobject is
just a matter of using the kobj member. Code that works with kobjects will
often have the opposite problem, however: given a struct kobject pointer,
what is the pointer to the containing structure? You must avoid tricks
(such as assuming that the kobject is at the beginning of the structure)
and, instead, use the container_of() macro, found in <linux/kernel.h>:
container_of(pointer, type, member)
container_of(pointer, type, member)
where pointer is the pointer to the embedded kobject, type is the type of
the containing structure, and member is the name of the structure field to
which pointer points. The return value from container_of() is a pointer to
the given type. So, for example, a pointer "kp" to a struct kobject
embedded within a struct uio_mem could be converted to a pointer to the
containing uio_mem structure with:
where:
struct uio_mem *u_mem = container_of(kp, struct uio_mem, kobj);
* "pointer" is the pointer to the embedded kobject,
* "type" is the type of the containing structure, and
* "member" is the name of the structure field to which "pointer" points.
Programmers often define a simple macro for "back-casting" kobject pointers
to the containing type.
The return value from container_of() is a pointer to the corresponding
container type. So, for example, a pointer "kp" to a struct kobject
embedded *within* a struct uio_map could be converted to a pointer to the
*containing* uio_map structure with:
struct uio_map *u_map = container_of(kp, struct uio_map, kobj);
For convenience, programmers often define a simple macro for "back-casting"
kobject pointers to the containing type. Exactly this happens in the
earlier drivers/uio/uio.c, as you can see here:
struct uio_map {
struct kobject kobj;
struct uio_mem *mem;
};
#define to_map(map) container_of(map, struct uio_map, kobj)
where the macro argument "map" is a pointer to the struct kobject in
question. That macro is subsequently invoked with:
struct uio_map *map = to_map(kobj);

Running Linux on the Voyager Architecture
=========================================
For full details and current project status, see
http://www.hansenpartnership.com/voyager
The voyager architecture was designed by NCR in the mid 80s to be a
fully SMP capable RAS computing architecture built around intel's 486
chip set. The voyager came in three levels of architectural
sophistication: 3,4 and 5 --- 1 and 2 never made it out of prototype.
The linux patches support only the Level 5 voyager architecture (any
machine class 3435 and above).
The Voyager Architecture
------------------------
Voyager machines consist of a Baseboard with a 386 diagnostic
processor, a Power Supply Interface (PSI) a Primary and possibly
Secondary Microchannel bus and between 2 and 20 voyager slots. The
voyager slots can be populated with memory and cpu cards (up to 4GB
memory and from 1 486 to 32 Pentium Pro processors). Internally, the
voyager has a dual arbitrated system bus and a configuration and test
bus (CAT). The voyager bus speed is 40MHz. Therefore (since all
voyager cards are dual ported for each system bus) the maximum
transfer rate is 320Mb/s but only if you have your slot configuration
tuned (only memory cards can communicate with both busses at once, CPU
cards utilise them one at a time).
Voyager SMP
-----------
Since voyager was the first intel based SMP system, it is slightly
more primitive than the Intel IO-APIC approach to SMP. Voyager allows
arbitrary interrupt routing (including processor affinity routing) of
all 16 PC type interrupts. However it does this by using a modified
5259 master/slave chip set instead of an APIC bus. Additionally,
voyager supports Cross Processor Interrupts (CPI) equivalent to the
APIC IPIs. There are two routed voyager interrupt lines provided to
each slot.
Processor Cards
---------------
These come in single, dyadic and quad configurations (the quads are
problematic--see later). The maximum configuration is 8 quad cards
for 32 way SMP.
Quad Processors
---------------
Because voyager only supplies two interrupt lines to each Processor
card, the Quad processors have to be configured (and Bootstrapped) in
as a pair of Master/Slave processors.
In fact, most Quad cards only accept one VIC interrupt line, so they
have one interrupt handling processor (called the VIC extended
processor) and three non-interrupt handling processors.
Current Status
--------------
The System will boot on Mono, Dyad and Quad cards. There was
originally a Quad boot problem which has been fixed by proper gdt
alignment in the initial boot loader. If you still cannot get your
voyager system to boot, email me at:
<J.E.J.Bottomley@HansenPartnership.com>
The Quad cards now support using the separate Quad CPI vectors instead
of going through the VIC mailbox system.
The Level 4 architecture (3430 and 3360 Machines) should also work
fine.
Dump Switch
-----------
The voyager dump switch sends out a broadcast NMI which the voyager
code intercepts and does a task dump.
Power Switch
------------
The front panel power switch is intercepted by the kernel and should
cause a system shutdown and power off.
A Note About Mixed CPU Systems
------------------------------
Linux isn't designed to handle mixed CPU systems very well. In order
to get everything going you *must* make sure that your lowest
capability CPU is used for booting. Also, mixing CPU classes
(e.g. 486 and 586) is really not going to work very well at all.
