The interface to the linux SYS_select call is different. It expects
|
|
a pointer to a small array containing the args, not the args as separate
|
|
args to the syscall(). This is due to limitations to the number of args
|
|
to syscall().
|
|
|
|
I don't think you can call this 'a bug' or 'broken'. It just isn't defined
|
|
the same. Use the select() library function, which is defined, and you
|
|
won't have these problems.

|

Of course this has been done in Linux all the time. Only in the Linux
|
|
world, there are less manufacturers who take up the responsibility for
|
|
writing a driver for their hardware... so the developers end up doing
|
|
both halves.
|
|
Check the SCSI drivers to see how they are divided in generic stuff and
|
|
manufacturer-specific stuff. In the ethernet drivers this is even more
|
|
clear, as many cards a based on the same controller chip(s) and can therefore
|
|
share a lot of code.

Well, for now you could just name the compiled bash shell bash-elf
|
|
and use that after you boot... Otherwise, I compiled the iBCS
|
|
stuff into the kernel a while ago, I'm sure it is possible with 1.1.51

with just a few patches. :)

I think that is 2.5 Mbit/sec, but M and K are adjacent on the

I like your idea, but I would change it slightly:
|
|
|
|
When you use a file on the CD, it gets copied to your hard drive. If
|
|
you don't use a file for a week (for example) and it is identical to one
|
|
on the CD, it gets deleted *IF* the space is needed and the directory is
|
|
not named in your do_not_hierarchically_erase control file.

Hierarchical storage management and demand-based compression would be great
|
|
features for those of us with limited hard disk space. (All of us? :-)

Subject: buffer.c & mounting disks

OK, this is what happened to me.
|
|
|
|
I had been running Slackware 1.2.0 for a while, until I compiled/patched the
|
|
kernel up to 1.1.51. This is where the problems started.
|
|
|
|
I often got "Warning: bdflush not running". I commented this out of
|
|
buffer.c, and it seems to look OK so far....
|
|
|
|
But, I've been having problems mounting floppy disks. This is a sample of
|
|
what happens:
|
|
|
|
mount -t msdos /dev/fd0H1440 /tmp/dos
|
|
d /tmp/dos
|
|
cp /tmp/end.compiling /tmp/dos/dummy.txt
|
|
umount /tmp/dos
|
|
|
|
that produced this here.....

Everything else has been great until I got the kernel up to 1.1.51... so
|
|
what's the problem and how can it be fixed?

By turning on the floppy drive motor, some of the status regs are updated.

I also know that FastBack can determine a disk has been inserted without the

drive light being on.

I have both the Ricoh and the HP that you mention. They both work fine. The
|
|
Ricoh is a 650MB drive. On both of them you are required to set a jumper to
|
|
make the drive work in a standard fashion and appear to the system to be just
|
|
another hard disk. By default both are in some sort of custom mode.
|
|
|
|
This operation was not entirely trivial on the HP. I had to use a wire wrap
|
|
tool to connect certain pins on the back that weren't immediatly next to each
|
|
other and thus couldn't be reached by an ordinary jumper. I don't off hand
|
|
remember which pins these were; but I figured it for myself by examining the
|
|
drive so you should be able to as well. Also HP refused to sell the drive in
|
|
an internal version; so I got the external and threw away the
|
|
case/power-supply.
|
|
|
|
Like most MO's performance is like an older HD on reading, much slower on
|
|
writes. If you aren't already aware, the 5 1/4 disks are double sided and
|
|
you have to manually flip them over to get rated capacity. The 650MB disks
|
|
are really only like 300MB/side, the 1.3GB are 600MB/side. The 3 1/2 disks
|
|
are single sided and you would actually get your full 128MB.
