Well, I added this instrumentation, but at the same time I also
removed "device apm" from the kernel config and added "apm_load="YES""
to loader.conf.local so that I could play with it more easily.
Rebuilt... rebooted...  needless to say, it works now!

apm0:  on motherboard
apm0: found APM BIOS v1.2, connected at v1.2

Does loading it as a module change the order in which apm and acpi
are probed?

It looks like I had not edited this kernel config since late 2004,
and had used it, i.e., with "device apm" included, for builds of
several 6.0 and early 6.1 kernels with apm being fine.

In the cvsup I did between 6.1-RC1 and the recent 6.1-STABLE, the
following 149 files had been updated.  Maybe this will help pinpoint
where something was changed...

Could you edit /usr/src/sys/i386/bios/apm.c and a go to line
which says:

printf("apm: Other PM system enabled.\n");

and replace it with:

printf("apm: Other (%d) PM system enabled.\n", 
(int)power_pm_get_type());

and recompile and install your kernels and modules? I suspect that
it will show 1 for the type, which means that acpi has somehow
claimed the power management even though it is supposed to be turned
off.

Regression: apm no longer works between 6.1-RC1 and 6.1-STABLE 2006/05/09

2006-05-10 Thread J.R. Oldroyd
I have just taken the system on a Sony Vaio PCG-Z505SX laptop from
6.1-RC1 (2006/03/23) to 6.1-STABLE (2006/05/09) using a cvsup update
and full buildworld/buildkernel rebuild, while keeping the same
kernel config.

On booting the new system, apm no longer works.  Now, acpi never
work on this hardware anyway, but apm always worked fine.  On the
6.1-STABLE kernel, it doesn't probe or load properly at boot time.
For reasons I no longer recall, "device apm" is configured in this
kernel, rather than loading it as a module, and this has been fine
for years, in fact, since back in the 5.x days and for several 6.0
kernels as well as 6.1-RC1.

Here's the pertinent boot info:


FreeBSD 6.1-RC1 (2006/03/23):

real memory  = 134152192 (127 MB)
avail memory = 121733120 (116 MB)
ACPI disabled by blacklist.  Contact your BIOS vendor.
npx0: [FAST]
npx0:  on motherboard
npx0: INT 16 interface
cpu0 on motherboard
apm0:  on motherboard
apm0: found APM BIOS v1.2, connected at v1.2
pcib0:  pcibus 0 on motherboard
pir0:  on motherboard


FreeBSD 6.1-STABLE (2006/05/09):

real memory  = 134152192 (127 MB)
avail memory = 121733120 (116 MB)
ACPI disabled by blacklist.  Contact your BIOS vendor.
cpu0 on motherboard
apm: Other PM system enabled.
pcib0:  pcibus 0 on motherboard
pir0:  on motherboard


On 6.1-STABLE, the /dev/apm device is not created and so none of
the apm tools work.

I don't see any changes to any of the apm code (in the last year
or so, actually), so this is presumably due to a change at a lower
level?

Any thoughts?
