parisc: Check kernel mapping earlier at bootup

2026-03-25T10:05:53+00:00

commit 17c144f1104bfc29a3ce3f7d0931a1bfb7a3558c upstream.

The check if the initial mapping is sufficient needs to happen much
earlier during bootup. Move this test directly to the start_parisc()
function and use native PDC iodc functions to print the warning, because
panic() and printk() are not functional yet.

This fixes boot when enabling various KALLSYSMS options which need
much more space.

parisc: led: Rewrite LED/LCD driver to utilizize Linux LED subsystem

2023-08-28T15:58:14+00:00

Rewrite the whole driver and drop the own code to calculate load
average, disk and LAN load. Switch instead to use the in-kernel LED
subsystem, which gives us quite some advantages, e.g.
- existing triggers for heartbeat and disk/lan activity can be used
- users can configre the LEDs at will to any existing trigger via
  /sys/class/leds
- less overhead since we don't need to run own timers
- fully integrated in Linux and as such cleaner code.

Note that the driver now depends on CONFIG_LEDS_CLASS which has to
be built-in and not as module.
