Re: port-i386/41267: 5.0 RC4 does not detect second CPU in VIA VT-310DP motherboard



Hello once again,

I investigated the problem more and I found the exact place where
something went wrong... I realized that tsc_read_bp function waits for
results whose come from tsc_post_ap (functions from tsc.c). I printed
some text after every step in tsc_post_ap and found that it stopped
printing before this line:

        /* Post result.  Ensure the whole value goes out atomically. */
        (void)atomic_swap_64(&tsc_sync_val, tsc);

I commented this line (I know that it is not a solution at all but I
just wanted to be sure) and to my surprise the second cpu started...
Unfortunately one more problem appeared with via ide drivers
(viaide0:0:0: lost interrupt), but I successfully booted NetBSD
without acpi support (-2vx). I posted dmesg below. If somebody will
help me to understand how atomic_swap_64 works on i386 architecture I
might try to localize the problem even more...

What is more I found that x86_ipi_init: ESR 00000040 problem comes
after first i82489_writereg(LAPIC_ESR, 0); call (so it wasn't related
problem). If I add two function i82489_writereg(LAPIC_ESR, 0) calls
one after another in x86_ipi_init then problem disappears and never
reappears. If I comment this line then I am getting the same error in
x86_ipi_startup function.

dmesg represents this two changes I described (commented
atomic_swap_64 line and added second i82489_writereg(LAPIC_ESR, 0);
call in x86_ipi_init), -2vx arguments used:

rbus: rbus_min_start set to 0x80000000
