This patch reduces the number of exception types by facilitating globally defined exceptions for common usage patterns shared by most services. In particular, RPC functions that demand a session-resource upgrade not longer reflect this condition via a session-specific exception but via the 'Out_of_ram' or 'Out_of_caps' types. Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable', 'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args', 'Service::Unavailable', and 'Local_service::Factory::Denied' types have been replaced by the single 'Service_denied' exception type defined in 'session/session.h'. This consolidation eases the error handling (there are fewer exceptions to handle), alleviates the need to convert exceptions along the session-creation call chain, and avoids possible aliasing problems (catching the wrong type with the same name but living in a different scope). |

This repository contains the Device Driver Environment for the "donator OS" iPXE available from http://ipxe.org/. For building DDE iPXE, you first need to fetch and patch the original sources. The 'prepare_port' tool automates this task. Just issue: ! ./tool/ports/prepare_port dde_ipxe Now, you need to include the DDE iPXE repository into your Genode build process. Just add the path to this directory to the 'REPOSITORIES' declaration of the 'etc/build.conf' file within your build directory, for example ! REPOSITORIES += $(GENODE_DIR)/repos/dde_ipxe After successful build the DDE iPXE based ethernet driver is located at 'bin/nic_drv'.
