Daniel Samson 28b4dabbaa serial: make the log sink a build option, off by default ... Serial is now a QEMU/dev aid, not a real-hardware necessity: a legacy-free board often has no live COM1, and the boot log is kept in RAM (klog) and flushed to disk. So the serial sink is compiled in only under -Dserial (default false). - kernel.zig gates serialInit + the log sink on build_options.serial - boot/efi.zig gates its EFI: progress breadcrumbs (con_out) via progress(); fatal-error messages stay always-on so a failed boot still explains itself - run-x86-64 boots a serial-enabled image variant (factored addKernel/addBootImage helpers) so a dev boot always captures serial0, without baking serial into the flashable image - test/qemu_test.py builds -Dserial=true (it asserts on serial markers) - the loopback probe stays as a real-HW safety net for -Dserial images		2026-07-13 22:05:08 +01:00
