presence: optimize emplace_back The emplace_back call is created using temporary strings obtained from a substr call which are not used past that point. Use std::move to avoid string copy during the emplacement. Signed-off-by: Patrick Williams <patrick@stwcx.xyz> Change-Id: I5b0c7eebfd7281a2be379192ccdb0b2e5e4d5828
phosphor-gpio-monitor
This daemon accepts a command line parameter for monitoring single gpio line and take action if requested. This implementation uses GPIO keys and only supports monitoring single GPIO line, for multiple lines, user has to run this daemon seperately for each gpio line.
phosphor-multi-gpio-monitor
This daemon accepts command line parameter as a well-defined GPIO configuration file in json format to monitor list of gpios from config file and take action defined in config based on gpio state change. It uses libgpiod library.
New implementation (phosphor-multi-gpio-monitor) provides multiple gpio line monitoring in single instance of phosphor-multi-gpio-monitor running. It is very easy to add list of gpios into JSON config file and it also supports of GPIO line by name defined in kernel.
There is a phosphor-multi-gpio-monitor.json file that defines details of GPIOs which is required to be monitored. This file can be replaced with a platform specific configuration file via bbappend.
Following are fields in json file
[ { "Name": "PowerButton", "LineName": "POWER_BUTTON", "GpioNum": 34, "ChipId": "gpiochip0", "EventMon": "FALLING", "Target": "PowerButtonDown.service", "Continue": true }, { "Name": "PowerGood", "LineName": "PS_PWROK", "EventMon": "BOTH", "Targets": { "FALLING": ["PowerGoodFalling.service", "PowerOff.service"], "RISING": ["PowerGoodRising.service", "PowerOn.service"] }, "Continue": false }, { "Name": "SystemReset", "GpioNum": 46, "ChipId": "0" } ]
