libfs/ FUSE on L4Re
by Stark, Josef 31 May '17

31 May '17

Hello, yesterday I came across a very interesting paper titled "Porting FUSE to L4Re", accessible here: http://os.inf.tu-dresden.de/papers_ps/pester-beleg.pdf For porting FUSE, the author uses a library called "libfs" which provides filesystem request forwarding and processing, if I understood correctly. It reads as if libfs is already included in L4Re. However, I couldn't find neither FUSE nor libfs in the current L4Re snapshot. Are they by any chance publicly available somewhere else, or are … [View More]

Question about memory management in L4 Fiasco O.C + L4re
by Mahdi Aichouch 04 Jan '16

04 Jan '16

Hello, I have some questions concerning memory management in Fiasco O.C + L4re. I would like to test two L4Linux instances, and for each L4Linux instance I want to reserve one static fixed physical memory partition. For instance, one 128MB for the first L4Linux and one 128MB for the second. Knowing that Fiasco O.C. uses "on demand paging" to allocate pages for user tasks, is it possible that each partition of L4Linux could be allocated a static physical memory region composed of contiguous … [View More]

issues in creating an elf binary
by AVK 31 Jul '15

31 Jul '15

Hello, I am trying to create an elf binary for the hello package (to start with) and when i run the `make elfimage` command, it fails with the following error make[3]: *** No rule to make target `mod.make.inc', needed by `bootstrap.ld'. Stop. While i am trying to look into the issue, maybe there is a quick fix for this, or someone has come across this issue already. Or maybe there is a better/easier way to create an elfimage.

20 Jul '15

Hello community, I have been trying to build l4re and have the following issue. I am building l4re snapshot with some other modules not included in the package. The issue is when i am building moe, and it has not been changed and is the one that is included in the package. I am building it on a virtualbox running xubuntu 15.04 (in case it helps to find the issue or could be the problem). I am not sure how to move ahead with this problem and am curious if anyone has ideas or pointers to look … [View More]

Some questions about L4 operating system
by Qing Wei 16 Jul '15

16 Jul '15

Hi, I am a beginner to L4, and very interested in it. I think it is great in terms of its minimality and security. However, I have some questions about it, (1) How is its performance compared to other monolithic kernel, say, Linux. Could it make use of multicore, multiprocessor to enjoy the performance scalability? (2) How is its ecosystem, fox example, how to support new hardware, does it need write the driver from scratch or could it make use of Linux driver? And how to write application … [View More]
