1. I need multiple VSpace "holes" to map page frames. This is the equivalent of what capdl_loader_app sets up in init_copy_frame. To do this I setup named static arrays and unmap the frame caps in camkes.c:post_main. This works but using a per-component attribute to enable this was awkward so I ended up adding a "copyregion" primitive to camkes. Is there a way to do this without adding to the camkes' syntax? It would also be nice not to allocate page frames only to release them at start but I didn't see a way to do this in capdl; is it possible (e.g. an easy way to leave an empty slot in the pt/pd)?
2. I pass capabilities with ipc msgs using camkes' rpc-connector templates. This requires multiple small changes that I want to enable only when being used (e.g. parameters to seL4_MessageInfo_new). My current plan is to add an optional keyword to a connection defn to enable support; e.g. connection seL4RPCCall foo(xfer_caps, from a, to b); Does this make sense or is there a better way? I rejected creating new connector templates that enable xfer_caps because I see this as a concept that applies to any ipc-based connector. _______________________________________________ Devel mailing list -- devel@sel4.systems To unsubscribe send an email to devel-leave@sel4.systems
