Core uses an instance of 'Pd_session_component' as a representative for RAM/cap quota accounts used whenever session resources are donated to core's services. All other facets of 'Pd_sesson_component' remain unused. Core's instance of 'Pd_session_component' is hosted at 'Core_env'. Upon its construction, all unused facets of 'Pd_session_component' are initialized by dummy arguments in 'Core_env'. To overcome the need for dummy arguments, this patch splits the accounting part of the PD-session interface into a separate 'Pd_account' interface. This gives us the prospect of narrowing core's current use of 'Pd_session_component' by 'Pd_account', alleviating dead code and the need for any dummy arguments. Issue #5408
This directory contains ports of 3rd-party libraries to Genode. Usage ----- The tool './tool/ports/prepare_port' in the toplevel directory automates the task of downloading and preparing the 3rd-party source codes. One can select individual ports that have to be prepared by specifying their base names (without the version number) as command-line argument. For example, the following command prepares both the C library and the Freetype library: ! ./tool/ports/prepare_port libc freetype To compile and link against 3rd-party libraries of the 'libports' repository, you have to include the repository into the build process by appending it to the 'REPOSITORIES' declaration of your '<build-dir>/etc/build.conf' file. Under the hood -------------- For each library, there is a file contained in the 'libports/ports/' subdirectory. The file is named after the library and contains the library-specific rules for downloading the source code and installing header files. How does 'libports' relate to the other repositories? ----------------------------------------------------- Most libraries hosted in the 'libports' repository expect a complete C library, which is provided via the 'libc' port. The libc, in turn, depends on the 'os' repository for its back end.
