Running a recent kernel under ARAnyM shows 40 ns resolution so the Atari hardware emulation is a little more complete.
You mean, 40 us resolution, right?
Using that for initial tests, I can confirm that timer resolution is reduced to 10ms after patch 6, and gets restored to 40ns after applying the full series
Thanks for testing!
(once clocksource_init runs, that is - the first part of the boot is at 10ms resolution only, a regression compared to with use of arch_gettimeoffset).
Sounds like a theoretical regression (?) Is there any need for more precise timers (I mean, better than 40 us) before clocksource_init runs?
Unfortunately, I can't log in at the console with all patches applied. I immediately get the 'login timeout exceeded' message. Weird...
I didn't see that in my tests... Was this aranym or real hardware or both? Can you also test tree fbf8405cd982 please? --
Cheers, Michael
