Use i386_set_ioperm() instead of ioperm(). See the manpage, although I think the arguments are the same. Use machine/cpufunc.h instead of asm/io.h (ignore the comment about sys/systm.h, that's a kernel-only include file). Ignore the setuid crap in the webpage, of course.

Re: console redirection to serial in Freebsd 5.1

but I think that doc was geared towards a 4.X release as it says that

However, reading the man page on the sio driver in 5.1-release man pages at
http://www.freebsd.org/cgi/man.cgi?query=sioapropos=0sektion=0manpath=Fre
eBSD+5.1-RELEASEformat=html
it seems that we just need to set those configs that used to be in the
kernel conf file in 4.7 in the
/boot/devices.hints file.
So I've set these options in the hints file to turn on the serial
redirection with the flag 0x90

hint.sio.0.port=0x3F8
hint.sio.0.flags=0x90

I've also set in the /boot.config file the -P flag to
set the console to the serial console in the presence of a keyboard.
and I've changed /etc/ttys to allow for the ttyd0 as well.
I am using the generic FreeBSD 5.1 kernel with the generic 5.1 kernel config
options,
but from what I read, I think I can still enable serial console redirection
with the generic kernel.
Any ideas as to what I might be missing to have the redirection to teh
serial console.

memory address space conversion
Hello all,
I ask a while ago a question and received great response. I'm hoping to
repeat the experience :)
I have a driver that I cannot change the ioctl API to. Unfortunately,
it has a peculiar need to return a user-space address based on the
physical address. Here is the scenario:
user calls mmap and gets a user-space mapping to a chunk of memory.
user calls an ioctl that passes an array of user-space addresses inside
that mapping.
I had a hack working for the case of a single-threaded process, but it
will not work in a threaded environment. Here is what I came up with:
static vm_map_entry_t find_entry (vm_map_t map, vm_paddr_t address)
{
vm_map_entry_t entry;
int i;
for (i = 0, entry = map-header;
i map-nentries;
i++, entry = entry-next)
{
vm_page_t page;
vm_paddr_t paddr;
if (entry-eflags MAP_ENTRY_IS_SUB_MAP)
{
vm_map_entry_t sub_entry =
find_entry (entry-object.sub_map, address);
if (! sub_entry) continue;
entry = sub_entry;
break;
}
if (entry-object.vm_object == NULL)
continue;
VM_OBJECT_LOCK (entry-object.vm_object);
page = vm_page_lookup (entry-object.vm_object,
OFF_TO_IDX(MMAP_OFFSET));
paddr = (page) ? VM_PAGE_TO_PHYS (page) : 0;
VM_OBJECT_UNLOCK (entry-object.vm_object);
if (paddr == address) break;
}
return (i map-nentries) ? entry : NULL;
}
where MMAP_OFFSET is 0x4000. This was the offset passed in by the
mmap call.
Does anyone know of a more proper mechanism that will work for the
threaded model? Any and all assistance will be greatly appreciated.
TIA,
Sean

ICH5 + SATA + Seagate Barracuda 7200.7 ?
Hello, I'm in the process of selecting new computers, and I'm tempted by an ASUS P4P800, with Seagate SATA disks. After googling a bit, it seems that the ICH5 is indeed supported in SATA mode from the 4.9-Release (perhaps also 5.1 ?) (at least the chip is correctly identified by http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ata-pci.c?annotate=1.32.2.17) The driver seems to be a bit fragile, if this message is to be relied on : http://lists.freebsd.org/pipermail/freebsd-stable/2003-November/004796.html Under Linux, the SATA support also is very recent : http://www.spinics.net/lists/kernel/msg223000.html it should be included in 2.4.23 So the question is : is there some actual, positive, experience in using the above combination, and with which stability ?

mtime and directories...
Changing a file, of course, results in a change to its modification time. Am I correct in determining that the mtime of the enclosing directory is also updated? The reason I'm asking this is because I need to be able to determine if any file has changed within a directory from a shell script, Perl, or Python. All I need to know is if at least one file has changed. I don't need to find all such files. [Sidelight: anyone know how, if possible, to stop find after finding one file? I can't figure this one out alone.] My initial solution was to use 'find' to find any files newer than a marker file. However, I believe I've determined that the mtime of enclosing directories also changes to reflect the last file that was updated within its hierarchy. So, it makes sense that I simply check the directory that contains the marker file.

secure file flag?
I am wondering if it is useful to have a secure file flag?? The secure file flag will be set for files that contain sensitive data. Then the OS will take special care when operating on those secure files. e.g. when deleting a secure file, the OS will overwrite the file with random data. One advantage would be to have secure files in the same filesystem as other normal files. Any one knows if FreeBSD has already implemented this?? Thanks, Rayson __ Do you Yahoo!?

Re: mtime and directories...
[EMAIL PROTECTED] said this stuff:
Changing a file, of course, results in a change to its modification
time. Am I correct in determining that the mtime of the enclosing
directory is also updated?
The mtime of a directory is updated when the directory file changes.
Directory files contain filenames and their associated inode numbers.
Modify any of that information (e.g., create a new file, remove or
rename an existing file), and the mtime will be changed. Changing the
ctime or mtime of a file within a directory does not modify that of the
directory itself.
The reason I'm asking this is because I need to be able to determine if
any file has changed within a directory from a shell script, Perl, or
Python. All I need to know is if at least one file has changed. I don't
need to find all such files. [Sidelight: anyone know how, if possible,
to stop find after finding one file? I can't figure this one out alone.]
% find /some/dir criteria |head -1
In this case, 'head' will exit after reading one line, causing 'find' to
receive a SIGPIPE if it tries writing more data. The 'find' command
doesn't typically trap SIGPIPE, so the process will exit. Of course, it
won't receive the signal immediately --- only if it calls write(2)
again, and on descriptor 1. If 'find' matches only one file, it will
wind up seeking through the entire tree. This may not be sufficient for
your application.
To truly make find exit after it matches one file, you can do something
along the lines of:
% prescript find /some/dir criteria -exec postscript '{}' \;
... where prescript contains a somewhat more error-tolerant version of
the following:
#!/bin/sh
echo $$ /pid/dir/find.pid
exec $@
... and postscript contains a somewhat more useful version of the
following:
#!/bin/sh
dostuffwith $@
pid=`cat /pid/dir/find.pid`
rm -f /pid/dir/find.pid
kill $pid
My initial solution was to use 'find' to find any files newer than a
marker file. However, I believe I've determined that the mtime of
enclosing directories also changes to reflect the last file that was
updated within its hierarchy. So, it makes sense that I simply check
the directory that contains the marker file.
Again, a directory's modification time is updated only if the actual
directory contents have changed, not the contents or inodes of the files
within it.

I'm in the process of selecting new computers, and I'm tempted by an ASUS P4P800, with Seagate SATA disks. ... is there some actual, positive, experience in using the above combination, and with which stability ? The ASUS P4P800 uses the Intel 865PE chipset. I have a Gigabyte 8KNXP which uses the Intel 875P chipset (almost the same thing) and a pair of Seagate ST3120026AS (120 GB Barracuda 7200.7) disks. They seem to work fine with FreeBSD 4.9-Release in either native or legacy mode even though 4.9-Release understands the ICH5 SATA controller only as yet another model of ICHx ATA controller. The driver thinks the disks are on an old 40 conductor IDE cable and tries to do dma at ATA33 speed, but the controller ignores the driver and runs at SATA150 rates. I used to operate the ICH5 SATA controller in native mode but had to switch to legacy mode because the AWARD BIOS won't boot off the controller in native mode. Legacy mode is less than ideal because the driver can't operate both drives at once. FreeBSD-current probably understands the SATA controller better than 4.9. I used to use 5.1-Release but had to give it up because it was just too flaky. (The rest of 5.1 was flaky. The 5.1 ATA driver seemed to work ok.) I have not attempted to upgrade to current because the traffic in [EMAIL PROTECTED] suggests that it works correctly only on alternate weekdays. I have made no real attempt to stress the disk system. It seems to work. I have used it to install FreeBSD several times and caused hours of continuous disk activity building ports and running miscellaneous programs. I have noticed no hiccups.
