Michael Brown c89a446cf0 [efi] Run at TPL_CALLBACK to protect against UEFI timers As noted in the comments, UEFI manages to combines the all of the worst aspects of both a polling design (inefficiency and inability to sleep until something interesting happens) and of an interrupt-driven design (the complexity of code that could be preempted at any time, thanks to UEFI timers). This causes problems in particular for UEFI USB keyboards: the keyboard driver calls UsbAsyncInterruptTransfer() to set up a periodic timer which is used to poll the USB bus. This poll may interrupt a critical section within iPXE, typically resulting in list corruption and either a hang or reboot. Work around this problem by mirroring the BIOS design, in which we run with interrupts disabled almost all of the time. Signed-off-by: Michael Brown <mcb30@ipxe.org>		6 lat temu
