@osxreverser@midnite_runr yeah, the next big milestone — network in SMM, probably it will be possible to use DMA buffer of NIC driver -
@d_olex@osxreverser@midnite_runr may be using AMT interface? -
@akochkov@osxreverser@midnite_runr Too lot of untrivial mess with hw interrupts in SMM, I want something more simpler and reliable

@d_olex@terrorobe Add some useful code, like being able to press stop-a! -
@FlorianHeigl1@terrorobe Reliable keyboard interaction from SMM (including USB etc.) might be untrivial -
@d_olex@FlorianHeigl1@terrorobe even legacy BIOSes must have a way to do it for their config screens..."just" gotta find that code :) -
@XenoKovah@FlorianHeigl1@terrorobe Yeah, but that code is DXE only, I need smth. for SMM :)
