Hi, Can someone point me to the relevant Fiasco.OC kernel changes made by Genode that might prevent the following error...
Could not assign parent interface to new PD unknown exception?
This is from vanilla r56 of Fiasco.OC. I'd like to see if I can get r56 running on Genode (to help me fix other issues).
Daniel

I am already at it, I can push a preliminary branch of r56 tomorrow, if you like, so you can check if the error still occurs.

Hi Sebastian, Yes, this would be a fantastic help. Daniel

Guess I'm quicker than expected .-) The relevant branch is:
https://github.com/ssumpf/genode/tree/r56
Make sure to run 'make clean' and 'make prepare' in 'base-foc'. If the error still occurs (I guess it's on x86_64), I would appreciate any help on how to reproduce it.
Sebastian
Hi Sebastian, Thanks for the code. I can confirm that it builds and runs fine (x86_64).
Unfortunately I still have my problem, but now I think it may have something to do with the kernel's internal Ram_quota for the process. Do someone at Genode know how this quota gets established?

Have a look at 'base-foc/contrib/kernel/fiasco/src/kern/config.cpp'. There is an enum value called 'kernel_mem_max' as well as constant called 'kernel_mem_per_cent'. Both should have an influence on how much memory the in kernel buddy allocator can use.
Greetings,
Sebastian
Thanks Sebastian, will do. As a first measure we have reduced the total number of memory mappings going on.
Thanks again, Daniel
