Shared dataspace problem
by Leon Brits 19 Jul '05

19 Jul '05

Hi all, I have a dataspace, reserved as pool 1 by dm_phys, which two tasks shares. They synchronise access to the data by setting a lock at the start of the dataspace with a cmpxchg-loop. All tasks map the dataspace to their own VM area. The problem is that if one of the tasks exists then the other would stop with a page fault error the next time it accesses the shared dataspace. Both of them where happily reading and writing to the dataspace at exactly the place where the page fault occur. Any suggestions? Thanks Leon

Unable to compile DROPS grub package
by Wang, Chip 19 Jul '05

19 Jul '05

Hi, I can't compile the DROPS version of GRUB. I checked out the grub package from the DROPS anonymous CVS. When compiling it with gcc 3.4.3 I got numerous errors. Each time I edited the source file to get it go a little farther, I got more errors. I know I could just use the copy of stage2_elterito from the demo CD, but I really like to have the capability to build my own GRUB. By the way, GRUB from GNU compiles successfully. But it lacks the features found in DROPS enhanced version. What was the problem? Excerpts of make logs from my five attempts are attached. It's a bit long. I apologize. Thanks, Chip (1) make all-recursive make[1]: Entering directory `/home/drops/modules/drops/grub' Making all in netboot make[2]: Entering directory `/home/drops/modules/drops/grub/netboot' make[2]:

How to load and run multiple instances of L4Linux, etc.
by Wang, Chip 18 Jul '05

18 Jul '05

Hi, My primary interest is to use Fiasco/L4Linux as a network emulator. To do so I'd like to run multiple copies of L4Linux on my PC, with each copy emulating a node in my network. I have just managed to get my compiled L4Linux-2.6 up and running using a copy of the GRUB menu.lst from the demo CD. But I am a new L4 user and have no idea on how to configure my boot to achieve this. Could someone suggest a sample menu.lst for booting multiple instances of L4Linux? Another novice question is how to run a Linux application on L4Linux. Can I simply add my application binary (e.g. XORP) that was pre-compiled for my desktop Linux to my L4Linux RAM disk? Or do I have to re-compile and link my app for L4 environment? Any help is greatly appreciated. Thanks, Chip The information contained in this e-mail message is PRIVATE.

L4Evn-2.6 Fails to Configure
by Kenji Miyamoto 16 Jul '05

16 Jul '05

According to the build instructions, a "make config" in the l4 directory will create a configuration menu. It doesn't seem to work in today's (07-16-2005) CVS version: l4 # make config make: *** No rule to make target `config'. Stop. l4 # make xconfig make: *** No rule to make target `xconfig'. Stop. There isn't a Makefile in the l4 directory, either. Why is this so? - Neil

RE: Error in building l4linux-2.6-env
by Wang, Chip 12 Jul '05

12 Jul '05

Hi Adam, I did not intentionally checkout dde. It just came with l4linux-2.6-env. I think it was part of the module. If it is not required to build l4linux-2.6 maybe you would want to separate it from the module? By the way, how can I receive CVS commit notifications via email, or is it even possible? I am looking forward to you publishing the fix soon.

The compiler error appears with more recent compiler versions, and I have now finally fixed it internally. Should be in our public CVS by tomorrow. On the other side, how did it come that you checked out dde? You don't need it to get L4Linux going.

L4Linux 2.4 server priority
by Leon Brits 12 Jul '05

12 Jul '05

Hi all, I have some questions with regard to the priority of a L4Linux server: Q1: In my loader script I set the "priority" parameter to what some help file somewhere (I think on the website) showed namely 0xA0. When I do a l4lx_thread_prio_get inside a kernel module I get the value "100". Is the loader "priority" parameter hex or decimal? [0xA0 -> 100 ????] Q2: If I set the "priority" parameter of a second L4Linux server to 0x30 I also get 100. Does this parameter actually work? - if not where is "100" defined? Q3: The API call l4lx_thread_prio_get() actually fails when the module loads complaining about exported symbols, while l4lx_thread_create() which is defined in the same header file (thread.h) and in the same source file (thread.c) works fine. Can somebody please help me understand this!? Q4: In the L4Linux server the kernel's priority is set based on a define named PRIO_KERNEL which is defined as 127. How does this PRIO_KERNEL defined value (and other PRIO_* values) relate to the "priority" parameter. Thanks Leon
