However, the bottom line is that there is no way for the kernel at all to know in advance that these events are going to be generated.Would a patch to handle this specific case be acceptable in the kernel though?We have quirks. :-) That said I think intel-hid could check the 0xCE event unconditionally in the "wakeup" mode, but that will be a separate patch on top of my series.
Thank you again, Rafael and Mario, to have helped understand the special behavior implemented on this system / BIOS combination. I guess I'll wait for your s2-idle-dell-test patch series to land first, to discuss then how to handle this other Dell model (with Alex Hung?). Or do you have another suggestion about how to proceed? In the meantime, I'll update the bug report I had created: https://bugzilla.kernel.org/show_bug.cgi?id=195897 to track and share there all the discoveries from this thread. Jerome
