This patch cleans up the thread API and comes with the following noteworthy changes: - Introduced Cpu_session::Weight type that replaces a formerly used plain integer value to prevent the accidental mix-up of arguments. - The enum definition of Cpu_session::DEFAULT_WEIGHT moved to Cpu_session::Weight::DEFAULT_WEIGHT - New Thread constructor that takes a 'Env &' as first argument. The original constructors are now marked as deprecated. For the common use case where the default 'Weight' and 'Affinity' are used, a shortcut is provided. In the long term, those two constructors should be the only ones to remain. - The former 'Thread<>' class template has been renamed to 'Thread_deprecated'. - The former 'Thread_base' class is now called 'Thread'. - The new 'name()' accessor returns the thread's name as 'Name' object as centrally defined via 'Cpu_session::Name'. It is meant to replace the old-fashioned 'name' method that takes a buffer and size as arguments. - Adaptation of the thread test to the new API Issue #1954 |

This repository contains device drivers ported from OpenBSD. Audio ##### The audio driver is ported from OpenBSD 5.7 and includes support for Intel HD Audio as well as for Ensoniq AudioPCI (ES1370) compatible soundcards. The HDA driver works on real hardware and Virtualbox whereas the ES1370 driver is only used in Qemu. Usage ===== You have to prepare the contrib sources for this repository by executing _./tool/ports/prepare_port dde_bsd_. Also you need to make sure to add the 'dde_bsd' repository to the REPOSITORIES variable in your 'etc/build.conf'. Example ======= The driver can be tested by executing the run script 'run/audio_out.run'. This example plays a sample file in a loop. The file format is header less two channel float 32 at 44100 Hz. You may use the 'sox' utility to create these audio files: ! sox -c 2 -r 44100 foo.wav foo.f32
