Wow, so you have already implemented a patch that exports the state in *human readable format* by sysfs. This patch was NACKed. Now it's expected that everyone in userspace will use ioctl() (with root permissions?) and translate any crazy bit array to something human readable. Right? Really?Dmitry, what are your thoughts on this? To clarify, there are 4 different switches that we need to read the state of. 1. XO-1.5 lid switch, exposed via ACPI via normal acpi-button driver 2. XO-1.5 ebook switch, exposed via drivers/platform/x86/xo15-ebook.c 3. XO-1 lid switch, exposed via arch/x86/platform/olpc/olpc-xo1-sci.c (linux-next) 4. XO-1 ebook switch, exposed via arch/x86/platform/olpc/olpc-xo1-sci.c (linux-next) We'd like to do this from shell code, as root.
add 2 more to that list as well in the near future: we are currently writing drivers for the lid and ebook switches on the ARM-based XO-1.75 laptop currently in prototype stages.
