The ioctl should take a (void *) to a buffer containing a structure which says how long the code is, followed by the code itself. That avoids the whole problem of reading a file from your driver, you can do it with a user-mode helper process. > If you can either tell me how to be able to read a file from my driver, > or point me to an example driver which does this, I would appreciate it.

Again, your best bet is to look at how the QUOTA stuff works; it reads and writes to the quota files. Heres the problem though; If you compile your kernel in, the root filesystem isn't mounted until after your drivers probe/attach routines have been called. It would be better if you made your firmware a KLD so that it can be loaded by the loader or demand loaded by the kernel linker when your driver is loaded. -- | Matthew N.

You're just going to have to grovel through the code somewhat, sendfile is sort of useful but you must have an already open file handle. There's other code you can get to do that, like the quota system (i'm pretty sure). -- -Alfred Perlstein - [[EMAIL PROTECTED]|[EMAIL PROTECTED]] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Can you repackage the binary as a data-only kld, with a couple of public symbols wrapping the beginning and end of the binary, or a couple of symbols with start and length? You could then have the loader pre- load the .ko at boot time. The only other way is to wait until the system is up and load the code into your driver through an ioctl. -- "Where am I, and what am I doing in this handbasket?"

True enough. The Alteon Tigon driver (sys/pci/if_ti.c) decides which one
of its firmware images (sys/pci/{ti_fw,ti_fw2}.h) based on the chip
revision.
So that's one possible example to look at.

Re: AMD Athlon and booting
Just FYI, my Athlon K7-700 with the ASUS motherboard won't boot
with an old IBM keyboard unless the reset button is pressed; the
screen remains blank. The ASUS web page says this happens in
certain combinations of keyboards and ATX power supplies. With
another keyboard it's fine.

Use an ioctl in your driver to pass in a pointer to your user address space which depending on the ioctl request the size of the file be written to the pointer, or that the pointer is where the device should copyout() or use one of the functions from STORE(9) to dump into the user address space. -- -Alfred Perlstein - [[EMAIL PROTECTED]|[EMAIL PROTECTED]] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
How to read a file from a device driver?
Can someone please tell me how I can read a file from a device driver in FreeBSD? I need to download 2 or 3 relatively-large code files to my device, choosing from amongst several different files depending on which mode I'm operating in. Therefore compiling-in the code is not a reasonable choice. If you can either tell me how to be able to read a file from my driver, or point me to an example driver which does this, I would appreciate it. I'm running FreeBSD 3.4.

I don't know what you're smoking, but there is no "probe_keyboard.c"
involved in this. The keyboard probe code is in boot2.c, and it looks
like this:
313 if (opts & 1 << RBX_PROBEKBD) {
314 i = *(uint8_t *)PTOV(0x496) & 0x10;
315 printf("Keyboard: %s\n", i ? "yes" : "no");
316 if (!i)
317 opts |= 1 << RBX_DUAL | 1 << RBX_SERIAL;
318 opts &= ~(1 << RBX_PROBEKBD);
319 }
There aren't any timing parameters there either. Either bit 4 in the
byte at 0x400:96 is set, or it's not.

procmap - Where does it belong?
A couple of months ago I was doing some work on guard pages in libc_r and
discovered that using 'cat' to view the VM map for a process is
unreliable. This fact is documented in the proc code, and there is even an
explanation of how to reliably read the map files. However, I could find
no program that actually does this, so I wrote one.
The program is attached (yes, it needs a man page if it is to be imported),
but my question is whether it belongs in the source tree, and if so, where?
Thanks,
Jason

Bootable CD Question
I have a custom kernel that I need to have boot from a cd across as many
machines as possible. I currently build the cd using scripts adapted from
what is in src/release, (I now owe Poul-Henning more than one beer), and
it boots every time in the lab, but people testing are reporting that it
will not boot on even newer machines. I realize that having a cd boot in
the PC world is an ify proposition, but does anybody have any tips on how
how to burn a more "reliable" bootable cd.
I am using mkisofs 1.12 with the following flags:
mkisofs -b floppies/boot.flp -c floppies/boot.catalog -d -N -D -R -T -l -V
'"Test"' -P '"Copyright"' -o ${BASE}/../../isoimages/image.iso ${BASE}
and cdrecord 1.8 with the following flags:
cdrecord speed=4 -v -data -multi dev=0,4,0 image.iso
I realize this might be more apropriate on questions, but if I don't solve
or at least have a better story about this problem very soon there may be
one less application available for FreeBSD, and I am working very hard
trying to prevent that :).
Thanks.

Netbooting FreeBSD 4.0/Intel?
This was originally posted to freebsd-questions, but I didn't get a response. I'm hoping that someone in here has successfully netbooted a FreeBSD 4.0-RELEASE box on Intel EtherExpress Pro 100+ cards and can share their story. Since I wrote this message, I have tried etherboot 4.4.5. Still no go. - Matt -- Matthew Zahorik Director of Systems and Networking - BiznessOnline.com [EMAIL PROTECTED] President of AlbanyNet Inc. - a BiznessOnline subsidiary [EMAIL PROTECTED]Voice: (518) 292-1001 Fax: (518) 626-0793 - Original Message - From: "Matthew Zahorik" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, March 16, 2000 1:40 PM Subject: Netbooting FreeBSD 4.0/Intel? : Does anyone have a howto on netbooting FreeBSD 4.0/Intel with Etherboot? : : I've easily managed to netboot my FreeBSD 4.0/Alpha boxes with the included : Alpha SRM netboot utility. I really like the bootp/NFS solution used by : netboot. It's quite clean, especially since I'm mounting root from this : same box. : : My Intel boxes are proving to be more difficult. : : Netboot is depreciated on Intel, and doesn't even seem to compile on FreeBSD : 4.0. Either way, it doesn't support the Intel Pro/100+ cards (82559 based) : I have in my Intel boxes. No bootp/NFS for the Intel boxes. :-( : : So I turned to Etherboot as suggested in many Usenet postings and the list : archives. : : I hand compiled the latest, etherboot 4.4.4. That didn't work. (see below) : : I used ports to install etherboot 4.2.13. (Had to change the Makefile since : it specifies 4.2.11, which isn't available anymore) This too didn't work. : : In both cases, I wrote floppyload.bin and eepro100.lzrun to a floppy. : Etherboot starts, gets its IP address from bootp, TFTP's the kernel, quickly : says "Loading Segment 1", "Loading Segment 2", "Loading Segment 3", and then : promptly reboots the machine. : : The kernel is compiled with all the option BOOTP.* bits - it should work. I've even : tried the generic kernel that I used to boot the server, knowing it would crash when trying : to mount root, but at least I'd see *something*. No go. : : So, if anyone has any pointers or a list of things you did to get this work, : I'd appreciate it. : : Thanks! : : - Matt : : -- : Matthew Zahorik Director of Systems and Networking - BiznessOnline.com : [EMAIL PROTECTED] President of AlbanyNet Inc. - a BiznessOnline subsidiary : [EMAIL PROTECTED]Voice: (518) 292-1001 Fax: (518) 626-0793 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

However, kernel config files are text files that indicate the config(8) what bits to compile into the kernel. If you have the FreeBSD kernel sources installed, you should have kernel config files in /sys/i386/conf. If you don't have the kernel sources installed, then having a kernel config file is quite useless.

It is a timing problem at least on some Athlon boards. On the MSI 6195, if you increase the timing parameters in probe_keyboard.c, the keyboard will get detected just fine. -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
