Just a quick add, my dmesg doesn't show acpi_cmbat entries.

Re: parameters for tsleep(9)
Hi,
1) man tsleep
2) tsleep is just msleep with NULL mutex.
if you check sys/kern/kern_synch.c you will
see KASSERT (ident != NULL && ...
ident is exactly the first parameter.

Norbert Koch:
Hello.
I am just writing a device driver for the i82527 (can-bus) chip.
For testing I need the driver to poll the chip instead of running
in interrupt mode.
My dev_t read function basically looks like this:
for (;;)
{
while (chip_has_data(...))
{
read_chip_data(...);
error = do_uiomove(...);
if (error || enough_read(...))
{
return error;
}
};
if (do_not_block_on_read(...))
{
return EWOULDBLOCK;
}
error = tsleep (XXX, PCATCH|PWAIT, "canrd", hz / 10);
if (error != EWOULDBLOCK)
{
return error;
}
}
XXX should be 'something' which could be used
as parameter to wakeup(9), I read in tsleep(9).
In the kernel source tree I found one
place where tsleep _only_ sleeps: in sys/isa/ppc.c
(which already seems to be in the attic [?] but
still is in my computer's source tree).
Here, the first parameter was set to NULL.
Doing this I found, that tsleep immediately
returns 0 (which means: wakueup was called)
_without_ waiting. I even crashed or
froze the kernel by calling tsleep (NULL, ...)
for a random number of times. After changing
this to the address of the read-function itself,
all worked fine. No more crashes.
Just for my understanding: Is this a bug?
Does the first parameter have to point to
something useful?
Is it allowed to point it to a code position?
Or should I use some kind of dummy data in
the softc structure instead?
What about the second parameter: Is PWAIT
ok here or should I use PZERO or whatever?
(And btw, why has ppc.c been removed?)
Thank you.

i386_set_ioperm on FreeBSD 5.3
Hi there. I'm trying to use some code I wrote quite a while ago using Doug White's FreeBSD IPMI code (kcs.c, send-kcs-command.c, etc.). It still works as it did back then on FreeBSD 4.10. On FreeBSD 5.3 it does not. Problem seems to be, that i386_set_ioperm isn't doing what it should. The program gets SIGBUS when doing outb, while it shouldn't. I looked in /usr/src/sys/i386/i386/sys_machdep.c, not many changes from 4.10 - all except one are additions that would return an error in case of failure. One seems to be quite modest (struct change): - if (p->p_addr->u_pcb.pcb_ext == 0) - if ((error = i386_extend_pcb(p)) != 0) + if (td->td_pcb->pcb_ext == 0) + if ((error = i386_extend_pcb(td)) != 0) Yet, clearly something fails on FreeBSD 5.3. I can confirm that this is indeed the problem with a few-line program that will i386_set_ioperm and then try to do outb. Any idea if i386_set_ioperm broke somehow in 5.3? Haven't checked much, but it seems that the data it is changing is not being used after all.
