Add a plugin which handles the connection of a Sixaxis device, when a new hidraw device is connected the plugin: - Filters udev events, and select the Sixaxis device - Sets LEDs to match the joystick system number (for USB and BT) - Sets the Master bluetooth address in the Sixaxis (USB pairing) - Adds the device to the database of the current default adapter (BT association) Signed-off-by: Bastien Nocera <hadess@xxxxxxxxxx> Signed-off-by: Antonio Ospite <ospite@xxxxxxxxxxxxxxxxx> --- Changes since previous version: - Use 'sixaxis' as plugin name because this is not a generic cable pairing mechanism. - Drop dependency on libusb, we can now use hidraw to send feature reports, since this patch has been accepted: https://patchwork.kernel.org/patch/485671/ - Other autotools cleanups (use UDEV_LIBS, check for the needed hidraw ioctls) - Rebase on latest bluez (s/debug/DBG/, use adapter_get_device(), etc.) - Misc fixes: change indentation, reorder includes and functions, etc. - Add support for setting LEDs according to the joystick system number. - Address some of Marcel's comments from the previous submission: http://marc.info/?l=linux-bluetooth&m=125525415718147&w=2 + Use hidraw + separate check for UDEV in the autotools changes A description of the udev part of the plugin can be found here: http://article.gmane.org/gmane.linux.kernel.input/18435 Makefile.am | 9 +- acinclude.m4 | 39 ++++ configure.ac | 1 + plugins/sixaxis.c | 506 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 553 insertions(+), 2 deletions(-) create mode 100644 plugins/sixaxis.c diff --git a/Makefile.am b/Makefile.am index adf6c84..f72ca19 100644 --- a/Makefile.am +++ b/Makefile.am @@ -202,6 +202,11 @@ builtin_sources += health/hdp_main.c health/hdp_types.h \ health/hdp_util.h health/hdp_util.c endif +if SIXAXISPLUGIN +builtin_modules += sixaxis +builtin_sources += plugins/sixaxis.c +endif + builtin_modules += hciops mgmtops builtin_sources += plugins/hciops.c plugins/mgmtops.c @@ -247,7 +252,7 @@ src_bluetoothd_SOURCES = $(gdbus_sources) $(builtin_sources) \ src/dbus-common.c src/dbus-common.h \ src/event.h src/event.c src_bluetoothd_LDADD = lib/libbluetooth.la @GLIB_LIBS@ @DBUS_LIBS@ \ - @CAPNG_LIBS@ -ldl -lrt + @CAPNG_LIBS@ @UDEV_LIBS@ -ldl -lrt src_bluetoothd_LDFLAGS = -Wl,--export-dynamic \ -Wl,--version-script=$(srcdir)/src/bluetooth.ver @@ -363,7 +368,7 @@ EXTRA_DIST += doc/manager-api.txt \ AM_YFLAGS = -d -AM_CFLAGS = @DBUS_CFLAGS@ @GLIB_CFLAGS@ @CAPNG_CFLAGS@ \ +AM_CFLAGS = @DBUS_CFLAGS@ @GLIB_CFLAGS@ @CAPNG_CFLAGS@ @UDEV_CFLAGS@ \ -DBLUETOOTH_PLUGIN_BUILTIN -DPLUGINDIR=\""$(plugindir)"\" INCLUDES = -I$(builddir)/lib -I$(builddir)/src -I$(srcdir)/src \ diff --git a/acinclude.m4 b/acinclude.m4 index 91e0956..5437816 100644 --- a/acinclude.m4 +++ b/acinclude.m4 @@ -147,6 +147,35 @@ AC_DEFUN([AC_PATH_USB], [ [Define to 1 if you need the usb_interrupt_read() function.])) ]) +AC_DEFUN([AC_PATH_SIXAXIS], [ + PKG_CHECK_MODULES(UDEV, libudev, udev_found=yes, udev_found=no) + AC_SUBST(UDEV_CFLAGS) + AC_SUBST(UDEV_LIBS) + + AC_CACHE_CHECK([for HIDIOCSFEATURE and HIDIOCGFEATURE (for Sixaxis plugin)], + [ac_cv_have_HIDIOCxFEATURE], + [AC_COMPILE_IFELSE( + [AC_LANG_PROGRAM([[ + #include <sys/ioctl.h> + #include <linux/hidraw.h> + #if !
