--- Comment #9 from Poul-Henning Kamp <p...@freebsd.org> ---
pstef@ ping'ed me on this one.
I have nothing much to add over the comment I put in atrtc_attach() in the
original commit (294643529963), but which has subsequently been lost:
/*
* Not that we need them or anything, but grab our resources
* so they show up, correctly attributed, in the big picture.
*/
I wanted to make the RTC resources show up in the accounting, for instance
devinfo -rv
For what it is worth, I get the warning also on my laptop (T480):
atrtc0: <AT realtime clock> port 0x70-0x77 irq 8 on acpi0
atrtc0: Warning: Couldn't map I/O.
atrtc0: registered as a time-of-day clock, resolution 1.000000s
I suspect the reason for the message is that acpi0 already claimed some of
those ports:
acpi0
Interrupt request lines:
0x9
I/O ports:
[…]
0x70
0x72-0x77
[…]
I guess, if somebody want to fix this, the ATRTC needs to be picked up through
ACPI rather than PNP ?
