Vadim Bendebury? This talk below? https://osfc.io/talks/google-secure-microcontroller-and-ccd-closed-case-debugging If so, is there a video or audio recording available? Thanks. > I think the momentary switch would not be acceptable to anyone for cost Small momentary switches cost pennies and laptops usually have about a hundred of them fitted, of various kinds. (Power on/off/suspend; volume up/down; keyboard keys; maybe others.) So, fitting laptops with momentary switches is definitely acceptable to manufacturers. > and reliability reasons. Such switches are often rated for ~100,000 cycles. It seems unlikely that any laptop or its owner would live long enough to flash the ROM chip even close to 100,000 times. So, I don't anticipate a reliability problem. > The way chromebooks do the protection now is really well done. I look forward to reading Vadim's slides, and perhaps also to watching or listening to his talk. Thanks for the pointer. -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
