To support the display of +signed sensor values, we add the attribute "sensorUnits1" to the sensor +mapping yaml. This attribute can be used to determine whether the +sensor is signed. + +It were making negative values 0 in get::readingData(). Fix the issue +by using a int32_t and add an overflow check. + +Change-Id: I705defcf18805db9ada7d0de0738a59aedab61df +Signed-off-by: Tony Lee <tony.lee@quantatw.com> +--- + include/ipmid/types.hpp | 2 ++ + scripts/sensor-example.yaml | 2 ++ + scripts/writesensor.mako.cpp | 2 ++ + sensordatahandler.cpp | 2 -- + sensordatahandler.hpp | 31 ++++++++++++++++++++++++++++--- + sensorhandler.cpp | 5 ++--- + 6 files changed, 36 insertions(+), 8 deletions(-) + +diff --git a/include/ipmid/types.hpp b/include/ipmid/types.hpp +index e62c8192..bd1fac2b 100644 +--- a/include/ipmid/types.hpp ++++ b/include/ipmid/types.hpp +@@ -133,6 +133,7 @@ using Unit = std::string;
