Disabling sti(4) by userconf(4) makes it boot, at least with serial console.

so it hangs at bus_space_map(9) or bus_space_read_1(9)?

>How-To-Repeat:
Boot patched GENERIC kernel on 712/60.

>Fix:
No idea.
Something special on serial console settings?

 I see the same problem also on my 712/60 with NetBSD-8 (8.0_BETA) and HEAD.

 9.1 still the same problem (freeze on probing sti(4)).
 I'll check HEAD after 9.1 upgrade is complete.

 More info:

 - stops at the first bus_space_read_1() in sti_sgc_probe():

 - happens even with "temporary local console" by pressign the "Esc" key:
  https://www.netbsd.org/ports/hppa/serialconsole-712.html#set_console_location

 - OpenBSD/hppa 6.8 just recognizes sti(4) on the same machine:

 Probably we have some order list to attach mainbus devices?
 (Currently we rely on config_found() so MI devices seem attached first)

 Please provide boot -v -x output. This should tells us more about how
 the devices are reported by the PDC.

 You might need to do this without sti @ in your config.

 Note OpenBSD/hppa seems probe I/O devices at mainbus in reversed order:
  http://bxr.su/OpenBSD/sys/arch/hppa/hppa/autoconf.c?r=1.62#211
 ---

 205 void
 206 pdc_scanbus(struct device *self, struct confargs *ca, int maxmod,
 207     hppa_hpa_t hpa, int cpu_scan)
 208 {
 209     int start, end, incr, i;
 210 
 211     /* Scan forwards for CPUs, backwards for everything else. */
 212     if (cpu_scan) {
 213         start = 0;
 214         incr = 1;
 215         end = maxmod;
 216     } else {
 217         start = maxmod - 1;
 218         incr = -1;
 219         end = -1;
 220     }
 221 
 222     for (i = start; i != end; i += incr) {
 223         struct confargs nca;
 224         int error;

 ---

 But the following kludge to reverse the probe order didn't help so much..

 hmm,

 not attached to lasi and

 Can you instrument the rom part

 Indeed.

 DPRINTF said
 > sti_sgc_probe: hpa=f8000000, rom=f8000000
 so sti_sgc_getrom() returned "rom = ca->ca_hpa".

 Finally I've found there is a dumb problem, i.e. the rom address
 taken from PAGE0->pd_resv2[1] (0xf0080000) just works:

 - OpenBSD/hppa doesn't check sti_sgc_opt[] values against
   ca->ca_type.iodc_revision for on-board (primary) sti(4)
 - sti_sgc_opt[] is different from OpenBSD (not sure why)
 - no info where STI_GOPT[1234567]_REV macros came from

 As the OpenBSD comment says:
 > /* gecko optional graphics (these share the onboard's prom) */
 so I wonder if sti_sgc_opt[] should be checked only against
 "optional" sti board.

 Miod Vallat also pointed out:
  https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/arch/hppa/dev/sti_sgc.c.diff?r1=1.35&r2=1.36

 so 0x60 was defined as STI_INEG_REV for "internal EG".

State-Changed-When: Tue, 20 Apr 2021 16:44:52 +0000
State-Changed-Why:
We need some method to check whether sti(4) framebuffer being probed is
on-board (primary) one and skip the revision check in sti_sgc_getrom()   
in such case.
