Hi everybody! Is there any tool out there, with which I can read files having the extension "&l3" with windows XP? I worked with the L3 system during my schooldays and found an old disk containing ELAN-code. I desperatly need to review this code, but unfortunately I can not install L3 because I do not have the Install-disks anymore! ---------------------------------------------------------------------------------------- Hallo Zusammen! Gibt es irgendwo ein Tool, mit dem ich ".&l3"-Dateien unter windwos XP lesen kann? Während meiner Schulzeit haben wir viel mit ELAN programmiert und ich habe eine Diskette, auf der verschiedene Quellcodes aus dieser Zeit sind. Ich muß diese Codes dringend lesen! Habe aber kein L3-System mehr auf meinem Rechner. ---------------------------------------------------------------------------------------- Thanks for any help Dankbar für jeden Tipp Alexander Grotzsch ________________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!

RE: qemu and l4linux2.4
by Volkmar Uhlig 16 Jul '04

There is a bug in the current interrupt handler code. I'm not 100% sure but I think we have a patch to that. The problem is that with Pistachio we run APIC interrupt mode and when IRQs are disabled they usually get re-injected with a self-IPI (I'm not arguing about the sensibility of that strategy though). Right now L4Linux doesn't do that and the IRQ gets lost. - Volkmar > > -- > Mat/tia Belletti - Undergraduate student @ cs.unibo.it > ICQ: 33292311 - email: mbellett(a)cs.unibo.it > IRC: RedGlow - site(s): http://www.cs.unibo.it/~mbellett > Linux registered user 299762 @ Linux registered machine 213003 > > _______________________________________________ > l4-hackers mailing list > l4-hackers(a)os.inf.tu-dresden.de > http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers >

qemu and l4linux2.4
by Mattia Belletti 16 Jul '04

16 Jul '04

I tried to run an l4linux (pistachio 0.4, l4linux from daily cvs), and it all went fine until: hda: QEMU HARDDISK, ATA DISK drive hdc: QEMU CD-ROM, ATAPI CD/DVD drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: attached ide-disk driver. irq 14 not enabled irq 14 not enabled IRQ resend (14) With quite a lot of delay after each of the two 'hda: QEMU HARDDISK...' and 'hdc: QEMU CD-ROM...', and, after that, it finally stops. Qemu runs normal linux fine - any idea where to go to find the problem? -- Mat/tia Belletti - Undergraduate student @ cs.unibo.it ICQ: 33292311 - email: mbellett(a)cs.unibo.it IRC: RedGlow - site(s): http://www.cs.unibo.it/~mbellett Linux registered user 299762 @ Linux registered machine 213003

paper about l4
by Fabian Sturm 04 Jul '04

04 Jul '04

Hi! I just wanted to let you know that I wrote a small paper about the L4 Microkernel for a seminar in my school. It's a summary of many of the information which is available on the various websites. I doubt that it has much usefulness since the reference manual and other sources are more detailed and precise. But anyways some might be interested. http://www.rtfs.org/ext/l4_microkernel.pdf Thanks a lot, Fabian P.s. even I already gave my talk I still would be interested in any wrong claims given in the paper.

The error "tempfile: command not found" on compliing fiasco.
by Daniel Yu 04 Jul '04

04 Jul '04

Hi all: I meet the troubles when "make config" the fiasco. After the graphic configure setting, the make process is stopped by error: .......... echo INT_CPP_x86_NAME= 'cat $X.out' >> ./.Makeconf.bid.converted;\ rm -f $X $X.{c,out} /bin/bash: line1: tempfile: command not found. .......... I have browsed the source code of Makefile, there is one sentence: X='tempfile -s .c' . But there is not a command named tempfile in bash or /bin, /sbin. Then what's wrong about the error? Thanks! Daniel

The build error on l4linux and fiasco!
by Daniel Yu 01 Jul '04

01 Jul '04

Hello All: I am a newbie for using u-kernel: fiasco and l4linux. However, I meet some problems when building them. For building l4linux: Under redhat 9.0, kernel version is linux-2.4.20-8 and gcc version is 3.2.2. After typing the command: "make config". the error is as following: /bin/sh scripts/Configure arch/l4/config.in : command not foundline 51: ' script/Configure: line 72: syntax error near unexpected token `{ ' script/Configure: line 72: ' function mainmenu_option () { make: *** [config] Error 2 Under the same environment, it is successful to build linux-2.4.20 kernel. So what's wrong? For Fiasco building, I get the other error information:(Using fiasco-1.1) Malformed UTF-8 character (unexpected continuation byte 0xb5, with no preceding start byte) in substitution (s///) at /fiasco-1.1/tool/preprocess/src/preprocess line 672, <> line 2058. When compiling process went this place, it dies and I must use CTRL-C to stop it. Can you give me some suggestions? Thank yu all very much!

L4 & ADX
by Frederic BOYER 29 Jun '04

29 Jun '04

Hello L4 hackers ! I restarted to work on my project ADX (write a real time unix like OS on top of L4). In fact I restart from scratch. I did not work on it since two years, and all my old sources died with my old computer and its hard drive. I plan to port GNAT run-time on top of L4 and begin to write the servers on top of it. do this projet interest any body ? Thanks to contact me and give me your feeling about this project.

KernelInterface @ IA32
by Louis 16 Jun '04

16 Jun '04

Hi L4 hackers, I'm a newbie in L4 and reading L4 X.2 spec. In IA32 interface, KernelInterface is implemented by 'lock: nop'. That really confuses me. Is it not just a placeholder? Any special side-effect? I can not find any clue in IA32 manuals. Yours truly, - Louis

ANNOUNCE: L4Ka::Pistachio version 0.4
by Espen Skoglund 04 Jun '04

04 Jun '04

The L4Ka team is happy to announce the release of L4Ka::Pistachio version 0.4. With L4Ka::Pistachio the L4Ka team aims at providing a robust, portable, high performance implementation of the L4 Version 4 API. It has been a long time since our last release, but we hope that all the new functionality and bug fixes were worth the wait. Among other things, the version 0.4 release adds support for 3 new hardware architectures. All in all the L4Ka::Pistachio kernel now runs on the following architectures: o Intel IA32 (Pentium and higher) o Intel IA64 (Itanium1, Itanium2, Ski) o AMD64 [NEW] o PowerPC 32bit (IBM 750) o PowerPC 64bit (Power3, Power4) [NEW] o Alpha (21164) o MIPS 64bit (R4000, VR41xx, R5000) o ARM (SA1100, XScale, ARM925T) [NEW] L4Ka::Pistachio version 0.4 incorporates a number of enhancements, modifications, and bug fixes. The following is a list of the major architecture independent changes since the last release: o Most system calls have been extended to report error codes upon failure. This substantially improves the ease of application development. o The kernel now implements "over-mapping" of flexpages correctly. Over-mapping occurs when a new page frame is mapped into the location of an already existing page frame in the destination address space. o Better support for reporting and resetting reference bits. o The ExchangeRegisters system call has been modified so that it can no longer activate inactive threads. o The L4 Version 4 API now specifies an architecture independent protocol for communicating boot loader specific data to the application programs. This protocol is supported by several L4 bootloaders (including kickstart). o Sigma0 now implements setting of memory attributes. o A bug (actually several bugs) in sigma0 would in some cases cause sigma0 to refuse to hand out certain memory regions, or cause incorrect memory to be handed out. o A new 'grabmem' example application has been added to the distribution. The following is a list of architecture specific changes and additions: Alpha: o Added FPU support. o Implemented SystemClock system call. AMD64: o This release adds support for the AMD64 architecture to L4Ka::Pistachio. o The AMD64 kernel is almost feature complete. It only lacks support for I/O flexpages and implementations of the Lipc, ProcessorControl and MemoryControl system calls. It also does not support SMP yet. o The kernel also features a hand-optimized fast IPC path. ARM: o This release adds support for the ARM architecture to L4Ka::Pistachio. o PLEB (Intel StrongARM SA-1100), Intel XScale IXP425 and TI OMAP1510 (ARM925T) platform support is included. o The kernel features fast address-space switching (FASS) [1] as a compile option. o The kernel is currently missing a fast-IPC path. Even without this optimization, context-switching and IPC performance across address spaces, when FASS is used appropriately, improves on any existing ARM implementation of L4 by approximately two orders-of-magnitude. o As with other architectures in L4Ka::Pistachio, currently no LIPC optimization is implemented - the LIPC path is identical to the IPC path. IA32: o Added a proper implementation of the SystemClock system call. o The support for small address spaces has been greatly improved. o Fixed a bug in the interrupt handing code that caused edge triggered interrupts to be handled incorrectly. o The kickstart utility now handles a number of command line options (see http://l4ka.org/projects/pistachio/kickstart.php for details). IA64: o The kernel now supports lazy handling of the upper 96 floating-point registers. o Preliminary support for performance profiling has been added. o Fixed a bug in the fast-IPC path that could cause interrupt handling to crash the kernel. o Low-level performance optimizations. o Fixed SystemClock system call to always report correct times. MIPS 64bit: o The kernel has been fixed to compile without debugging. o Added support for NEC VR41XX processors. o Changed the system call encoding. o The fast-IPC path has been fixed. o Reworked the exception handling code. o More accurate timer implementation. o Floating point support. o SMP support. PowerPC 32bit: o The kernel can run without debugging and without the debugger. o Proper exception message dispatching, including support for the system call exception. o Added correct implementation of the SystemClock system call. o Can prevent verbose kernel initialization. o Added a user-level I/O driver for the psim COM port, which can be used when the kernel is compiled without debug support. o Code restructuring to (1) minimize code, (2) improve readability, and (3) parameterize more kernel features. PowerPC 64bit: o This release adds support for the 64 bit PowerPC architecture to L4Ka::Pistachio. o The kernel supports Power3 and Power4 architectures (no SMP). o Optimized selective SLB replacement context switching on Power4. For more information on L4Ka::Pistachio and the L4 Version 4 API in general, refer to the L4Ka::Pistachio whitepaper: http://l4ka.org/projects/pistachio/pistachio-whitepaper.pdf L4Ka::Pistachio is available under the two-clause BSD license. Source and binary distributions, documentation, and other online resources can be found on the L4Ka website: http://l4ka.org/ The latest version of L4Ka::Pistachio, including any changes since the latest release, is also available through a public read-only CVS repository.
