DMA addressing limitations

Does your device have any DMA addressing limitations? For example, is

on the PCI bus for SAC DMA transfers? If so, you need to inform the

|

32-bits in a SAC cycle. For a 64-bit DAC capable device, this needs

to be increased. And for a device with limitations, as discussed in

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

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.
|
||||
|
||||
NOTE: Support of notifications should be implemented for the control
|
||||
file. See documentation for the subsystem.

Gmail (Web GUI)
|
||||
|
||||
If you just have to use Gmail to send patches, it CAN be made to work. It
|
||||
requires a bit of external help, though.
|
||||
Does not work for sending patches.
|
||||
|
||||
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.
|
||||
|
||||
Gmail is not convenient for lkml patches, but CAN be made to work.
|
||||
Another problem is that Gmail will base64-encode any message that has a
|
||||
non-ASCII character. That includes things like European names.

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;

question. That macro is subsequently invoked with:

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.
