From 3ea10b38bbb4b471178793f68fbd3a0ee74449f6 Mon Sep 17 00:00:00 2001 From: Paul Davis Date: Tue, 13 Apr 2010 20:48:33 +0000 Subject: substantive change: use the JACK wait API and provide "thread buffers" separately from session in preparation for parallelization. lots of debug output at present. If using JACK1, requires a very current version of JACK1 SVN (0.119.0) git-svn-id: svn://localhost/ardour2/branches/3.0@6888 d708f5d6-7413-0410-9779-e7cbd77b26cf --- libs/ardour/ardour/thread_buffers.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 libs/ardour/ardour/thread_buffers.h (limited to 'libs/ardour/ardour/thread_buffers.h') diff --git a/libs/ardour/ardour/thread_buffers.h b/libs/ardour/ardour/thread_buffers.h new file mode 100644 index 0000000000..3c312176a8 --- /dev/null +++ b/libs/ardour/ardour/thread_buffers.h @@ -0,0 +1,33 @@ +#ifndef __libardour_thread_buffers__ +#define __libardour_thread_buffers__ + +#include + +#include "ardour/chan_count.h" +#include "ardour/types.h" + +namespace ARDOUR { + +class BufferSet; + +class ThreadBuffers { + public: + ThreadBuffers (); + ~ThreadBuffers (); + + void ensure_buffers (ChanCount howmany = ChanCount::ZERO); + + BufferSet* silent_buffers; + BufferSet* scratch_buffers; + BufferSet* mix_buffers; + gain_t* gain_automation_buffer; + pan_t** pan_automation_buffer; + uint32_t npan_buffers; + + private: + void allocate_pan_automation_buffers (nframes_t nframes, uint32_t howmany, bool force); +}; + +} // namespace + +#endif /* __libardour_thread_buffers__ */ -- cgit v1.2.3
