First, you need -O (or O1, O2) on the compilers command lina.,
There are inlines that only get inlined when optimizing, so
when compiling for the kernel alway optimize.
And second, you need to define _KERNEL_
The kernel include try to protect user space programs from
seeing kernel only data structures.

The only thing I found in the FAQ was that symbols starting with "_dl_" come
from the dynamic linker.
So I still have no idea how to my problem .

I've tried and tested a Linux version for the Psion Series 5. It used up most
of my 8Mb memory (kernel, "disk-image" etc.) but it works! Getting stuff to and
from the Linux S5 was awkward because it had to be in diskimages. It's been a
while since I last played with it, so I've forgotten where I got it from. Must
have been the "PsionKing" site or something.

<chuckle> Of all programs out there EMACS and Mozilla are probably the most
anti-UNIXish in design. Come on, both are obviously intended for use on
systems with *very* slow equivalents of fork(). In case of EMACS it definitely
was *not* UNIX - even mentioning that OS together with UNIX was enough to

Compiling the kernel with SMP support is not enough to stop it :-) Mine was
compiled as SMP and poweroff worked as long I had only one CPU in the machine.
Plugging a second CPU caused poweroff to stop working and brought a second
boot-time penguin :-)
If you find something post it. I'm would also like to reenable it. I didn't
search for it that far, because it was nice-to-have, but not really important.
I only found a boot-time message from apm saying that apm is not smp safe -
disabling apm. Docs in /usr/src/linux confirmed this.
I'm more interrested in ACPI at the moment as that is completely unknown
matter to me :-)

I found the boot/boot.0300 file and dd'd it back to /dev/hda. This
fixed my boot process just fine. I also got my test compiled version
to load and run. So I'm armed and dangerous now :-)

Yeah, I probably should have. It's not so simple tho.
The computer that runs linux isn't connected to anything else,
so I'd have to retype everything by hand (no big deal for lilo.conf,
but I'm lazy!).
In fact, that's why I'm messing with it. I did get the test boot
to work, and the recompiled kernel runs, but not as I expected.
So now I get to figure out why. At least lilo makes sense now.
Thanks for the help, I got a few ideas from this group that got me
back up and running.

Subject: Problem with vremap function
Date: Mon, 14 Jun 1999 12:03:55 +0200
Hi. (I'm under Linux SuSE 6.0 (kernel 2.0.36))
I'm developping a driver for industrial PCI card. Each card have 2Ko of
memory.
The first card has an adress: 0xFF000000
The second has an adress: 0xFF000800
My problem is that vremap can't maps the second memory.
vremap use this define:
PAGE_SHIFT = 12
PAGE_SIZE = 1 << PAGE_SHIFT #0x00001000
PAGE_MASK = ~(PAGE_SIZE-1) #0xFFFFF000
~PAGE_MASK= #0x00000FFF
This is the minimum of page size
Error provide in the second card with the test: if (adress &
~(PAGE_MASK)) return NULL
with adress is the physical adress.
For the first card: 0xFF000000 & 0x00000FFF => return virtual
adress
For the sedond card: 0xFF000800 & 0x00000FFF => return NULL
How can I resolve this error ?
Can I reduce the page size ?
Or, must I use other function than vremap ???
Thanks for your help.

There is also, somewhere, a "restricted" shell, I do not
remember its name - but it could be "rsh", and there is a
name clash with the "remote" shell "rsh".
With it, the user can do "ls" but nothing more... mostly
not "chsh".

There are others like qmail and postfix. If you want an ISP strength
mail transport agent then sendmail is the usual choice. Easier
configuration is avaialable as sendmail pro (sendmail+GUI
configuration tool) from sendmail inc, whose techincal support should
be good (if need be Eric himself is avialable). There are lots of
consultants out there who will install and configure sendmail for you.
Both these options will cost you money, of course.
Things you read and write mail with are a sepereate question. Popular
choices include pine and elm. There are varuious GUI ones too--I like
exmh but it is not for everyone.

Doing a grep of the kernel gives me this:
drivers/block/xor.c: "raid5: using high-speed MMX checksum
routine\n");
drivers/block/xor.c: xor_speed(&t_xor_block_pII_mmx,&b1,&b2);
drivers/block/xor.c: xor_speed(&t_xor_block_p5_mmx,&b1,&b2);
I saw some funny messages during boot time - doing 1GB/sec XORs or
somthing which
is very impressive. I suspect you only get those kind of numbers if you
use some vector
kinds of instructions.
Wow, you made me think I was dreaming ... :)

What new ideas? No, don't just point at your essay, give us a
reasonable abstract. One single paragraph that presents one new idea
that you have proposed. Go for it. I'm not asking for code, just a

Yes, although it is probably better to use egcs: see

process of taking over gcc maintenance, so you would
not really be straying from the gcc path.)

On the contrary; here our enterprising essayist :-) has actually
stumbled across something. Consider the Synthesis Kernel (Massalin and
Pu SOSP'89, etc.]. Synthesis had a run-time code generator in the OS
that would emit code specific to applications being run at the time.
This specialized code could be viewed as "caching" the state of the
system it is to support. There was one particularly brilliant example
where the ready queue was implemented as a "linked list" comprised of
chunks of code that would jump directly from one control block to the
next, instead of having a scheduler traverse and "interpret" the ready
queue.
Synthesis was actually implemented and ran. Benefits were largely in
the I/O system It showed speedups of up to 400 times on the essential
"cat bigfile >/dev/null" benchmark :-)
Disclaimer: I worked on the follow-on Synthetix project, producing the
Pu et al (... Cowan ...) paper in SOSP'95. We did Synthesis-like
things inside the HP-UX kernel, producing speedups in the x3 range.
