Hi Danial,
I have a Ram_connection which is running out of cap indexes - "cap index allocation failed". How do I increase the quota for these? I understand I can construct my own cap session, but its not clear how to get the Ram_connection to use it. Context is Genode on Fiasco.OC/amd64.
the message refers to the name space of capability selectors (the IDs as understood by the kernel) within a Genode process. The name space is dimensioned statically via a template argument to the 'Cap_index_allocator_tpl' class template. For core, you find the definition in 'base-foc/src/core/cap_session_component.cc':
https://github.com/genodelabs/genode/blob/staging/base-foc/src/core/cap_sess...
For all processes outside of core, the definition can is located in 'base-foc/src/base/env/cap_alloc.cc':
https://github.com/genodelabs/genode/blob/staging/base-foc/src/base/env/cap_...
The name space for core is dimensioned larger than for other processes because core needs to keep track of all capabilities present in the Genode system. Please give it a try to increase the dimensions of the capability-selector name spaces.
Cheers Norman
