parisc: Convert PDC console to an early console

2022-10-11T10:01:24+00:00

Rewrite the PDC console to become an early console.
Beside the fact that now boot information is visible until another
(text- or graphics) console takes over, this benefits as well machines
with a yet-unsupported STI console and kgdb.

parisc: Autodetect default output device and set console= kernel parameter

2022-01-20T19:39:19+00:00

Usually palo (the PA-RISC boot loader) will check at boot time if the
machine/firmware was configured to use the serial line (ttyS0, SERIAL_x)
or the graphical display (tty0, graph) as default output device and add
the correct "console=ttyS0" or "console=tty0" Linux kernel parameter to
the kernel command line when starting the Linux kernel.

But the kernel could also have been started via the HP-UX boot loader
or directly in qemu, in which cases the console parameter is missing.

This patch fixes this problem by adding the correct console= parameter
if it's missing in the current kernel command line.

parisc: Mark sched_clock unstable only if clocks are not syncronized

2021-09-09T10:44:31+00:00

We check at runtime if the cr16 clocks are stable across CPUs. Only mark
the sched_clock unstable by calling clear_sched_clock_stable() if we
know that we run on a system which isn't syncronized across CPUs.

arch/parisc/setup: Drop dummy_con initialization

con_init in tty/vt.c will now set conswitchp to dummy_con if it's unset.
Drop it from arch setup code.
