> Looks the same as the other mail. Enter helps? Actually, what do you > expect to see? :) Thanks. I also read another mail with the same situation. I use Slackware 12.0 not Ubuntu because in Ubuntu there is a glibc bug which has been existed at least for more than half year - "undefined reference to __stack_chk_fail". This bug has been reported many times and has committed to the Ubuntu Bug List. But bug is as before. The first question: the l4 boot log is like this: l4lx | l4lx_thread_create: Created thread 10.16 (IRQ5) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 4. l4lx | l4lx_thread_create: Created thread 10.17 (IRQ4) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 3. l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 2. l4lx | acquire_irq: Error attaching to IRQ 2 l4lx | l4lx_thread_create: Created thread 10.19 (IRQ2) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 1. l4lx | acquire_irq: Error attaching to IRQ 1 It seems that when attaching IRQ1, IRQ2, IRQ9, IRQ12 there are some errors like "acquire_irq: Error attaching to IRQ x". But later attaching IRQ is ok. What is the matter? IRQ1 and IRQ12 are related with keyboard and monse, IRQ2 is related with cascade, IRQ9 is about acpi. I have removed these drivers from linux. why is it also like this? The second problem is: The Linux booting stops at /ect/random-seed to initialize /dev/urandom and there is no login interface. I have checked the normal linux booting and after the using /ect/random-seed to initialize /dev/urandom the linux will finish booting kernel, enter the linux user space "INIT: Entering init X". So I think it is still the problem of l4linux kernel not the special linux distribution. Is it right? Thank you very much. Cheng Guanghui

I want to use lmbench, bonnie++ and > AIM-suite9, my questions are: - How can I use those benchmarks when I boot > Fiasco? I think lmbench, bonnie++ and AIM-suite9 are not suitable when you compare l4/fiasco with ecos although they are real-time operating systems. L4 itself is not linux binary compatible but l4linux could provide full linux binary comptability. And these benchmark tools must run on the linux-binary-compatible system such as BSD,UNIX, etc. So we could compare l4linux with linux by using lmbench, bonnie++ and AIM-suite9. Although ecos could provide many linux APIs but it is still not linux binary compatible. In common we can't compile these tools on the ecos so the benchmark is impossible. Additonal lmbench, bonnie++ and AIM-suite9 are designed for the general purpose operating system. From the result we could know the average performance of the system. Therefore, if you want to compare l4 with ecos you could take these two system as real-time systems and you should get some data showing real-time performance such as jitter, responsing time, etc. But there is no benchmark tool which could cover these two platforms : l4 and ecos. So you have to write your application for this goal. Thanks Cheng Guanghui

In this paper I use lmbench, bonnie++ and AIM-suite9. But I don't use lmbench, bonnie++ and AIM-suite9 to test the Fiasco itself but test the the performace loss between l4linux-2.6.16 and linux-2.6.16. In this benchmark I login into l4linux with a console because in this way we could ignore the effection of graphic interface for performance loss. It is not complex but only a confiugration problem. If you want to login l4linux with console you could use the configuration file like this: modpath "(hd0,2)/boot/L4Linux" task "vmlinuz26" "earlyprintk=yes console=ttyS1,115200 init=3 mem=256M" root=/dev/hda3" all_sects_writable Is this clear?

I'm sorry for my mistake. I've found a benchmark to use. I've got a questions: Where do I put the benchmark to use it in L4 Fiasco console? How can I launch the benchmark in the L4 Fiasco console? Thanks for your help. Davide Fasoli ___________________________________ L'email della prossima generazione? Puoi averla con la nuova Yahoo! Mail: http://it.docs.yahoo.com/nowyoucan.html
