Nov 15, 2019 AvsCamera - AVStream camera sample driver: Provides a pin-centric AVStream capture driver for a simulated front and back camera that performs simulated captures at 320x240 or 640x480 in RGB24, RGB32, YUY2 and NV12 formats at various frame rates. AVStream simulated hardware sample driver (Avshws). Osst-users — Discuss issues with the use of osst, the OnStream tape driver for Linux. Data management is also one of our strategic objectives and MISTRAS Digital is a discrete way to integrate our vast data capabilities. Onstream Streamview PCMS software our ruggedized MISTRAS. Windows device driver information for OnStream ADR50. Some tape changers require tape dev to be specifically defined. Others will may use their very own device mechanism others use a separate device changer and others will simply ignore this function. On Linux the OnStream drive, which uses the OSST driver is one such example, and it is known to work with Bacula. In addition a number of such tape drives (i.e. OS drivers) seem to work on Windows systems.
Introduction.
This page coordinates the development of a Linux tape driver for the OnStream SC-30/SC-50/DI-30/FW-30/USB-30 devices. The target, osst, is a kernel driver that provides an st-compatible interface to the userspace. The driver is put under GPL and submitted to the kernel folks for inclusion into the mainstream kernel.
There is an IDE tape driver in the kernel with support for the OnStream DI-30, which uses the same basic format for the tapes defined by the ADR spec. It was written by Gadi Oxman. The OnStream functionality in ide-tape has not been maintained though, so its use is not recommended.
This project is a joint effort of indiviuals that want to get their OnStream ADR SCSI / IDE / IEEE1394 / USB tape drive to run with Linux and any Backup Software available on Linux. The primary author and maintainer is Willem Riede. We were supported by OnStream and SuSE. Unfortunately OnStream has gone bankrupt and the development has now moved to SourceForge.
Status.
The driver currently supports 2.6.x and 2.4.y kernels. A 2.2 version is alsoavailable, but has not been updated with some of the latest fixes.Osst comes standard with all recentkernels from kernel.org or your favorite distribution.
Download the latest version (which may not yet be merged at kernel.org)here.
DISCLAIMER: If you test it, you do it on your own risk. If the drivercrashes your kernel (unlikely, but possible) and you loose important data,you are on your own. If you use the driver to backup your data and need torestore it later, but fail, you are on your own again. If something badhappens to you because of this driver, don't even try to make somebodyresponsible for this. There is no warranty of whatever kind. In short:The GNU GPLapplies.
- 2005-01-01
- Osst-0.99.3 released. Improves error handling of polling problems on DI-30. Solid implementation of sysfs support, now hotplug+udev can manage the osst device nodes. Coding style changes to accommodate current preferences of the Linux kernel team.
- 2003-12-29
- Osst-0.99.2 released. Provides initial sysfs support which replaces the /proc support in 0.99.1. For each attached drive, a directory with attributes is created:
- 2003-12-23
- Osst-0.99.1 released. It brings the 2.6.x version of osst up to par with the 2.4.y version (0.9.14). Tested against released 2.6.0 kernel.
- 2003-12-14
- Osst-0.9.14 released. It fixes an issue with behavior expected by Bacula, a backup software package.
Changes:
- Made osst adhere to standard Unix behavior when reading at EOD (return zero bytes read twice, then i/o error)
- Implemented SETBLK ioctl (only allowed before first write - does not affect read, as osst uses the block size used when the file was written) - 2003-12-01
- Migration of the osst repository to SourceForge complete.
- 2003-06-28
- osst 0.9.13 released
- 2003-04-28
- OnStream enters Bankruptcy procedings.

Mailing list
A mailing list is there to provide an easy way for the users and developers to communicate. The name is osst-users@lists.sourceforge.net, and it's a mailman list. To subscribe visit the list's web page at osst-users-request.
Using osst.
SC-30/50
You need to use a kernel that has generic SCSI support enabled (scsi_mod is thename of the module) and with osst compiled and installed. Device nodes need toexist (if they don't, use MAKEDEV or mknod):
To have osst be loaded automatically when you refer to any of the devices,add this line to /etc/modules.conf:
DI-30/50
On top of the requirements for the SC model, you need to use ide-scsiwith the device. You'll want to tell the kernel to do so when you boot,using hdx=ide-scsi (where you substitute the right device letterfor the x) to the grub or lilo configuration.
FW-30
Drivers Onstream Data Sheet
On top of the requirements for the SC model, you need to activate theIEEE1394 subsystem, and load the sbp2 driver.
USB30
On top of the requirements for the SC model, you need to activate theUSB subsystem, and load the usb-storage driver. Furthermore, it needsto be compiled with support for the FreeCom USB-Atapiconverter CONFIG_USB_STORAGE_FREECOM.
Useful Information.
Drivers Onstream Data Recovery
- There are firmware updates available for various OnStream drives.
- This site offers Manuals and Technical Support Documents for the OnStream drives.
- This page contains important information for using osst with various backup software packages.
- On the T10 committee web site you can find the draft versions on the SCSI specs that underly OnStreams's ADR spec.
Development.
For the joint development, a CVS repository is available on SourceForge. It handles the driver sources and also the web pages.
The repository contains the modules (=directories) WebPages, Driver, Docu, Firmware and Misc.
In Driver you find osst itself and a bunch of files used in its original creation, which are now obsolete. Three branches exist, for the 2.2 (OSST22), 2.4 (LINUX-2-4) and 2.6 kernel (HEAD).
The Docu directory contains the docu from OnStream, namely the ADR spec as a PDF. More documentation will go here.
The Firmware directory contains DOS and Wind*ws programs to update the firmware of your OnStream tape device.
CVS read access is available through browsing. If you have some contributions, the diffs (use diff -u) should be sent to the mailing list and someone will have a look and check it into the CVS. If you are contributing a lot, it will be easier to give you read-write access to the repository, so ask to join as a developer.
