Subject: [ANNOUNCE] Dolphin PCI-SCI RPM Drivers 1.1-4 released
--45Z9DzgjV8m4Oswq
Content-Type: text/plain; charset=us-ascii
Linux Kernel,
The RPM versions of the Dolphin PCI-SCI (Scalable Coherent Interface)
adapter drivers have posted at vger.timpanogas.org/sci. This release
supports the following SCI Adapters, PSB32, PSB64, and PSB66. This
version supports the 32-bit and 64-bit PCI versions of the Dolphin
PCI-SCI Adapters. This RPM version supports i386, Alpha, Sparc, and
Sparc64 architecture systems.
SCI is a high performance clustering interconnect fabric that allows
a Linux system to perform push/pull DMA transfers of mapped regions
of memory (such as a distributed cache) between nodes either via
DMA or via remotely mapping R/W memory access to pages of memory
in another cluster node. This version of the adapters supports
a scalable fabric on bi-CMOS chipsets that operates with a
maximum data transfer rate of 500 Megabytes/second. Obviously,
PCI bandwidth limits how much throughput you can actually get
on a Live Linux System. On an AMD Ahtalon 550Mhz System, we are
seeing @ 65 Megabytes/second with DMA and @ 45 Megabytes/second
throughput with Memory copying between nodes with this
version of the drivers/adapters.
Linux 2.2 vs. 2.4 performance is telling, with Linux 2.4 clearly
providing significantly higher performance for NUMA
operations with the Dolphin PCI-SCI adapters. Please review
the attached performance figures below for a comparison.
This release has removed the requirement for the bighysparea patch
for these drivers. This package will allow these drivers to run
on any "shrink-wrapped" Linux versions. We have also packaged these
drivers in both tar.gz and RPM format, and a source RPM is provided
under the GNU Public License which will allow these drivers to be
easily included into any commercial Linux Distributions that use
RPM. We have tested this RPM package on RedHat, Suse, Caldera,
and Ute Linux.
This release has been tested and 2.4 Linux kernel enabled, and fully
supports Linux kernel 2.4. This release corrects several bugs
and level I Oops on Linux 2.4 kernels with previous versions.
Please feel feel to post any bugs or problems with these drivers to
linux-kernel@vger.kernel.org or report them to jmerkey@timpanogas.org.
I will be maintaining the RPM release of the Dolphin PCI-SCI drivers,
so please direct and reports to me and I will forward them onto
Dolphin ICS if they are related to hardware bugs. For additional
useful information about SCI, please visit Dolphin's website
at www.dolphinics.com.
The next release of these drivers will contain a fast-path sockets
and TCPIP interface to allow IP routing and support for LVS and
distrbuted NUMA support for the M2FS Clustered File System on the
Dolphin Adapters.

RPM (RedHat Package Manager) installation notes for DIS PCI-SCI Adapters
------------------------------------------------------------------------
This release contains the Dolphin PCI-SCI adapter drivers for the PSB32,
PSB64, and PSB66 adapters in RPM (RedHat Package Manager) package
format.
These packages are built using the RPM build utility. The RPM format
is 3.04, and is compatible with RPM versions 3 and versions 4. RPM
packages are provided in both source (.src.rpm) and binary forms
(.i386.rpm, .alpha.rpm, etc.). A binary RPM package contains the
drivers and driver installation scripts needed to install or
remove a version of the PCI-SCI drivers from your Linux systems.
The source RPM package contains the source code and build scripts
needed to rebuild the binary RPM packages for a target system. If
you are using modversioned kernels, you will need to rebuild the
binary packages for your system against the source RPM package.
All commercial Linux distributions use the RPM tools to administer
packages and verify dependencies and version matches required to
support a particular package. If you are using a system that does
not support RPM, please visit Dolphin's Website at www.dolphinics.com
for a copy of the latest .tar.gz or tar version of the PCI-SCI
drivers for your Unix or Linux system.
This release consists of the following RPM packages note: %{version} is the
RPM package version release number:
RPM source package:
pci-sci-%{version}.src.rpm
RPM binary packages:
Intel X86:
pci-sci-PSB32-%{version}.i386.rpm
pci-sci-PSB64-%{version}.i386.rpm
pci-sci-PSB66-%{version}.i386.rpm
Sparc:
pci-sci-PSB32-%{version}.sparc.rpm
pci-sci-PSB64-%{version}.sparc.rpm
pci-sci-PSB66-%{version}.sparc.rpm
pci-sci-PSB32-%{version}.sparc64.rpm
pci-sci-PSB64-%{version}.sparc64.rpm
pci-sci-PSB66-%{version}.sparc64.rpm
Alpha:
pci-sci-PSB32-%{version}.alpha.rpm
pci-sci-PSB64-%{version}.alpha.rpm
pci-sci-PSB66-%{version}.alpha.rpm
Installing RPM source and binary packages
-----------------------------------------
It is recommended that you rebuild the .src.rpm if you are using a kernel
build with modversions enabled, and install the binary RPM packages created
from this build. You must have a valid and properly configured
kernel build sources tree located in the /usr/src/linux directory
on your system in order to rebuild the PCI-SCI drivers. Please consult
the /usr/src/Linux/Documentation directory or the /usr/src/Linux/README
file for specific instructions on setting up your kernel build tree.
To rebuild a source RPM on a target system, enter the following command:
rpm --rebuild pci-sci-%{version}.src.rpm
This command will install the source files into the RPM build tree
on your system and rebuild all the binary packages. This tree is always
found at /usr/src/($distribution)/ and contains BUILD, SOURCES,
SPECS, SRPMS, and RPMS subdirectories. ($distribution) is the name of
your Linux distribution. For example, if your Linux distribution is
Red Hat, then this directory would be located at /usr/src/redhat/.
If your distribution is Caldera Linux, the this directory would be
located at /usr/src/OpenLinux/. It's a good idea to simply list
the contents of /usr/src/ to locate your particular RPM build tree
for your commercial Linux distribution.
The recompiled binary RPM packages will be found after the build
finishes at /usr/src/($distribution)/RPMS/($arch). ($arch) is
the architecture of the system on which you are building. If you
are rebuilding the source RPM package on an Intel System on
RedHat 6.2, then this directory would be /usr/src/redhat/RPMS/i386.
If you are rebuilding the source RPM package on an Alpha System on
RedHat 6.2, then this directory would be /usr/src/redhat/RPMS/alpha.
To install either the pre-built or the rebuilt RPM binary packages
simply type the following command dpending on which PCI-SCI adapter
is in your system (PSB32, PSB64, PSB66):
rpm -i pci-sci-PSB64-%{version}.i386.rpm
You can also force RPM to overwrite previously installed versions
of the pci-sci drivers with this command:
rpm -i --force pci-sci-PSB64-%{version}.i386.rpm
You should see several messages on the system console detailing
the progress of the PCI-SCI driver installtion. They should
look something like this:
#
#
# rpm -i pci-sci-PSB64-1.0-1.i386.rpm
pci-sci reports this system has 1 processor(s) (LINUX)

To remove the PCI-SCI drivers from your system, enter the following
command with the proper adapter type installed in your system:
rpm -e pci-sci-PSB64
Messages similiar to the following should be displayed on the system
console.
#
#

Jan 24 22:38:04 nwfs kernel: Trying to free free IRQ9
Querying RPM information
------------------------
If you need to query whether the RPM packages have been installed or
not in your system, type the following command:
rpm -q pci-sci-PSB64
This should produce output similiar to the following:
#
#
# rpm -q pci-sci-PSB64
pci-sci-PSB64-1.0-1
#
#
Additional useful information concerning the options and versions of
the RPM tools can be found by visiting the RPM website at www.rpm.org
or by typing 'info rpm' or 'man rpm' from your system console. The
man and info listing on RPM contains detailed information about
using the RPM tools.
rpm --help | more
will also provide additional information about querying RPM options
that are available.
Rebuilding the RPM from the pci-sci-%{version}.spec file
-------------------------------------
If you want to rebuild your .src.rpm and binary rpm packages from
the RPM build tree, then you can change directory (cd) into the
/usr/src/$(distribution)/SPECS directory. This directory will
contain the rpm .spec files for any installed .src.rpm packages
either installed via rpm -i <rpm name>.src.rpm command or the
rpm --rebuild <rpm name>.src.rpm command. An RPM spec file is
a file containing install scripts and build instructions for
an RPM package or set of packages, along with versioning and
dependecy information.
To rebuild the PCI-SCI drivers from the SPECS directory, type
the following command:
rpm -ba pci-sci.spec
This command will trigger complete rebuild of the .src.rpm and
binary rpms for the PCI-SCI package.
Increasing the Number of SCI Nodes Supported
--------------------------------------------
This version of the PCI-SCI adapters will support up to 256
clustered SCI nodes. To increase the number of nodes supported,
you will need to change the following line in the
/src/IRM/drv/src/id.h file, line 36 contained in the pci-sci-1.1.tar.gz
file contained in the source RPM. This file will normally be
located in the /usr/src/$(distribution)/SOURCES directory.
#define MAX_NODE_IDS 256
This value can be increased up to 1024 nodes. Increasing this value
will also increase the amount of memory needed to setup the SCI
mbx structures from 130K to 520K.
