Brian Gianforcaro	3a945051fc	Kernel: Use operator ""sv in all purpose() implementations ... Previously there was a mix of returning plain strings and returning explicit string views using `operator ""sv`. This change switches them all to standardized on `operator ""sv` as it avoids a call to strlen.	2021-10-03 13:36:10 +02:00

Liav A	8d0dbdeaac	Kernel+Userland: Introduce a new way to reboot and poweroff the machine ... This change removes the halt and reboot syscalls, and create a new mechanism to change the power state of the machine. Instead of how power state was changed until now, put a SysFS node as writable only for the superuser, that with a defined value, can result in either reboot or poweroff. In the future, a power group can be assigned to this node (which will be the GroupID responsible for power management). This opens an opportunity to permit to shutdown/reboot without superuser permissions, so in the future, a userspace daemon can take control of this node to perform power management operations without superuser permissions, if we enforce different UserID/GroupID on that node.	2021-09-12 11:52:16 +02:00
Liav A	33f033066c	Kernel: Unify BIOS and ACPI components in the SysFS firmware directory ... Both should reside in the SysFS firmware directory which is normally located in /sys/firmware. Also, apply some OOM-safety patterns when creating the BIOS and ACPI directories.	2021-09-12 11:52:16 +02:00
Liav A	9132596b8e	Kernel: Move ACPI and BIOS code into the new Firmware directory ... This will somwhat help unify them also under the same SysFS directory in the commit. Also, it feels much more like this change reflects the reality that both ACPI and the BIOS are part of the firmware on x86 computers.	2021-09-12 11:52:16 +02:00
