- From the keyboard of volker@sfb256.iam.uni-bonn.de ( Volker A. Brandt ):
- :I would like to generalize the question: Is anyone out there seriously
- :thinking about porting 386BSD to a Motorola platform?
-
- Apparently so. I have this marketing glossy in my hands from
- the company named in the subject line with the following claims:
-
- Processors Supported
- (figure)
-
- MC68040 VMEbus systems - Motorola MVME167, Synergy SV410
- MC68030 Motorola MVME147 (Planned)
- 80386/80486 Most IBM PC-AT Class systems, clones, and industrial PC's
- Mips R3000 Planned for Late 1992
- i860 Planned for Late 1992
- Sparc 2 Planned for Early 19934
-
- We started with the NET/2 release of Berkeley BSD, added many proved
- real time extensions and POSIX 1003.1 complaince. RTMS is a complete,
- ready-to-run system at a price anyone can afford. We have added a
- realtime scheduler, shared physical memory, message exchanges,
- high-resolution timers, named binary semaphores, and contiguous file
- support to the BSD system. These powerful enhancements, with support
- for the proposed POSIX 1003.2 and POSIX 1003.4 specifications bring
- the most powerful and standardized solution to the systems developer.
- Full Berkeley Networking, Release 2 source is available with every
- system.
-
- Each RTMX-RealTime POSIX System is user-tuneable for optimum
- performance as either a development, or run time system environment.
- RTMS contains no AT&T code, which means, there is NO AT&T license
- required, no royalties to pay, and no hidden costs.
-
- RTMX memory management implements a demand-paged, virtual memory
- system. A Contiguous file system as well as a standard file system
- are included. The Contiguous file system transfers data directly
- between the task's memory and the disk. With this Direct Memory
- Access (DMA), extraordinarily high data rates are achieved and
- transfers can take place simultaneously with other activities.
-
- RMTX is binary compatible with Sun UNIX. It complete with *ALL*
- [underlining theirs --tchrist] required tools, compilers, debuggers,
- and libraries. We include GNU ANSI `C', C++, and an entire suite of
- GNY tools such as: flex, bison and emacs. The GNY text processing
- system groff and TEX are included to provide you, the user with a
- high-quality text output mechanism. Binary compatibility opens the
- door to hundreds of popular, commercially available systems like:
- databases, spreadsheets, statistical, CAD, telecommunications,
- instrumentation, text and word processing.
-
- RTMX Networking provides effortless data sharing, gateways between
- dissimilar system types and extensibility for complex environments.
- RMTX has standard TCP/IP and OSI protocol support, full BSD socket
- library, and a thoroughly re-worked Network File System (NFS) to
- provide fast, transparent, reliable interprocess, intertask
- communication and files.
-
- Binary Compatibility
-
- Intel '386, '486 versions SCO UNIX V.3.3
- Motorola M68030, M68040 Sun 3 Unix (1)
- Sparc versions Sun 4 Unix (1)
-
- (1) (non-Sun View, non-Shared Library Programs)
-
-
- RTMX-RealTime POSIX offers a full MIT X Window, Versions 11 Release 5
- option for all systems. We have carefully compiled, optimized, and
- integrated the thousands of modules which make-up the X Window system
- and combined them into a complete implementation. We include the very
- popular Open Systems Foundation (OSF) Motif(tm) toolkit and window
- manager with every X Window package.
-
- RTMX offers complete source code, thousands of on-line documentation
- pages, telephone support, product updates, and training seminars. Our
- many years of experience in realtime systems, special device drivers,
- and complex appi.cations greatly enhance the value to any user.
-
- RMTX has been written almost entirely in the C language code to ensure
- hardware independence and ease of portability. Systems are being
- released for Motorola M68030 and M68030, Intel 80386 and 80486, Sparc
- 2 and Mips R3000.

- Task Context Switching Model
- (figure)
-
- Interrupt Level Context Switch <8 usecs
- Service-to-Schedule Context Switch 19.5 usecs
- Full Path CC context Switch 95 usecs
- System call via getpid() 30 usecs
-
- (Benchmarks performed on an MC68040 CPU running at 25 Mhz,
- 4/3/3/3 DRAM access)
-
-
- Pricing seems seems to run from $300 for a dedicated applications
- environment with no development activity, up to $2000 for a full system
- with annual maintenance, updates, bug fixes, and telephone support for
- networking and X windows systems on 386 and 486 PC's. They also have
- various 3rd party applications available.
-
- Apparently you should should direct email inquiries to
- krl@rmtx-uniflex.com, who's listed as the Kenneth Lewis,
- director of sales.
-
- I have no affiliation with these folks. I just found the brochure to be
- fascinating for many reasons, which I'm sure will be discussed here at length.
