This has some side effects +when bombarded data pushed to port 80. + +With this change, if same post code is written on LPC channel +it will be set but D-Bus will not emit the 'PropertiesChanged' +signal. Actually there is no need to emit the signal if actual +property value(postcode) is not changed. + +So if post code changes, D-Bus will emit the signal as usual +with this code. Any client applications depends on this, still +can register for signal for knowing postcode change. + +Renamed bbappend file for generic notation. + +Tested: + - Manually verified by setting different post code, + emits the signal. + + busctl set-property xyz.openbmc_project.State.Boot.Raw + /xyz/openbmc_project/state/boot/raw0 xyz.openbmc_project.State.Boot.Raw + Value t 00 + + dbus-monitor --system "type='signal',member='PropertiesChanged', + interface='org.freedesktop.DBus.Properties', + path_namespace=/xyz/openbmc_project/state/boot/raw0, + arg0=xyz.openbmc_project.State.Boot.Raw" + + - Verified functionality with real post code changes. + +Change-Id: I13e7879a19ada593891821df3702613cc8e84572 +Signed-off-by: AppaRao Puli +Signed-off-by: Zhikui Ren +--- + main.cpp | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/main.cpp b/main.cpp +index 3a3b4ce..764c855 100644 +--- a/main.cpp ++++ b/main.cpp +@@ -66,7 +66,7 @@ void PostCodeEventHandler(sdeventplus::source::IO& s, int postFd, uint32_t, + // HACK: Always send property changed signal even for the same code + // since we are single threaded, external users will never see the + // first value. +- reporter->value(std::make_tuple(~code, secondary_post_code_t{}), true); ++ // reporter->value(std::make_tuple(~code, secondary_post_code_t{}), true); + reporter->value(std::make_tuple(code, secondary_post_code_t{})); + + // read depends on old data being cleared since it doens't always read +-- +2.25.1 + -- cgit v1.2.3
