This feature is implemented on some systems using an IPMI OEM command:<br>
<a href="https://github.com/openbmc/google-ipmi-sys#delayedhardreset---subcommand-0x03" rel="noreferrer" target="_blank">https://github.com/openbmc/google-ipmi-sys#delayedhardreset---subcommand-0x03</a><br>
<br>
It currently just activates the systemd target<br>
gbmc-psu-hardreset.target and lets you register services to do the<br>
actual hotswap reset (usually by toggling a GPIO). Having a unified<br>
solution in x86-power-control for this would be great!<br>
<br>
Ben, Can you please share content of<br>
<a href="https://github.com/openbmc/google-ipmi-sys/blob/master/gbmc-psu-hardreset.target" rel="noreferrer" target="_blank">https://github.com/openbmc/google-ipmi-sys/blob/master/gbmc-psu-hardreset.target</a><br>
as my assumption is each platform needs to provide this file but I couldn't find any platform<br>
using this. I only found reference in meta-quanta which is deleting this file. So please<br>
provide a reference to this file.<br>
<br>
