The interface is asynchronous and bi-directional.\n\nThere are quiet a few changes since the RFC,\n\n- Switch to an event notifications and signals for the ingress code \n path, making the interface asynchronous.\n- Removed any protocol helpers in the IPC object, a protocol should be \n implemented on top of the IPC.\n- Added documentation.\n- Switched to SOCK_DGRAM.\n- Send both data and file descriptors in the same sendmsg().\n- Fixed spelling and silly errors in the code.\n- Merged test case in a single binary.\n\nNiklas Söderlund (2):\n libcamera: ipc: unix: Add a IPC mechanism based on Unix sockets\n test: ipc: unix: Add test for IPCUnixSocket\n\n src/libcamera/include/ipc_unixsocket.h | 59 +++++\n src/libcamera/ipc_unixsocket.cpp | 288 +++++++++++++++++++++\n src/libcamera/meson.build | 2 +\n test/ipc/meson.build | 12 +\n test/ipc/unixsocket.cpp | 339 +++++++++++++++++++++++++\n test/meson.build | 1 +\n 6 files changed, 701 insertions(+)\n create mode 100644 src/libcamera/include/ipc_unixsocket.h\n create mode 100644 src/libcamera/ipc_unixsocket.cpp\n create mode 100644 test/ipc/meson.build\n create mode 100644 test/ipc/unixsocket.cpp" }
