From 8f301ca04fca91fcba4d8f6f70200b4f9a006d66 Mon Sep 17 00:00:00 2001 From: Matthieu Herrb Date: Wed, 25 Nov 2009 18:10:26 +0000 Subject: Implement device properties for calibration data. Setting the properties also write to the kernel table. The calibration code can now change the data without quitting X. --- Makefile.am | 2 +- include/Makefile.am | 2 + src/Makefile.am | 2 + src/ws.c | 130 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 135 insertions(+), 1 deletion(-) create mode 100644 include/Makefile.am diff --git a/Makefile.am b/Makefile.am index 52b7eba..657885c 100644 --- a/Makefile.am +++ b/Makefile.am @@ -14,4 +14,4 @@ # OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. # AUTOMAKE_OPTIONS= foreign -SUBDIRS= src man +SUBDIRS= src man include diff --git a/include/Makefile.am b/include/Makefile.am new file mode 100644 index 0000000..15138e4 --- /dev/null +++ b/include/Makefile.am @@ -0,0 +1,2 @@ +EXTRA_DIST = ws-properties.h +sdk_HEADERS = ws-properties.h diff --git a/src/Makefile.am b/src/Makefile.am index 50ece5d..1ed52fa 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -19,4 +19,6 @@ AM_CFLAGS = $(XORG_CFLAGS) @DRIVER_NAME@_drv_la_LDFLAGS= -module -avoid-version @DRIVER_NAME@_drv_ladir= @inputdir@ +INCLUDES=-I$(top_srcdir)/include/ + @DRIVER_NAME@_drv_la_SOURCES = @DRIVER_NAME@.c diff --git a/src/ws.c b/src/ws.c index d838244..f90482f 100644 --- a/src/ws.c +++ b/src/ws.c @@ -36,6 +36,16 @@ #include #include +#if GET_ABI_MAJOR(ABI_XINPUT_VERSION) >= 3 +#define HAVE_PROPERTIES 1 +#endif + +#ifdef HAVE_PROPERTIES +#include +#include "ws-properties.h" +#endif + + #if GET_ABI_MAJOR(ABI_XINPUT_VERSION) >= 7 #include #include @@ -81,6 +91,13 @@ static Bool wsOpen(InputInfoPtr);
