Reply-To: Tony Houghton <[EMAIL PROTECTED]>
I want to change the framebuffer colormap so that I can set a very deep
background colour to my consoles for everyday use. I find the usual
black makes it a bit too stark for comfort, and just a very slight tinge
eases it a bit.
I nosed around the relevant part of the kernel source and a program
someone sent me to "fix" resolution settings for all virtual consoles
when using an ATI card (although I'm now using a Matrox G200). I came up
with this at the heart of it (error checking snipped for brevity):
cmap.start = STARTCOLOUR;
cmap.len = NUMCOLOURS;
cmap.red = malloc(NUMCOLOURS * sizeof(__u16));
cmap.green = malloc(NUMCOLOURS * sizeof(__u16));
cmap.blue = malloc(NUMCOLOURS * sizeof(__u16));
cmap.transp = 0;
fh = open(FBDEVICE, O_RDONLY);
ioctl(fh, FBIOGETCMAP, &cmap);
cmap.red[0] = (__u16) red;
cmap.green[0] = (__u16) green;
cmap.blue[0] = (__u16) blue;
ioctl(fh, FBIOPUTCMAP, &cmap);
This works, but the colours aren't "fixed", ie when I change to a
different virtual console, and even then come back to the original one,
it goes back to black. I tried a couple of ways to make the change
permanent:
ioctl(fh, FBIOGET_VSCREENINFO, &var);
/*var.activate = FB_CHANGE_CMAP_VBL;*/
var.activate = FB_ACTIVATE_NOW;
ioctl(fh, FBIOPUT_VSCREENINFO, &var);
IIRC, FB_CHANGE_CMAP_VBL doesn't make any difference, FB_ACTIVATE_NOW
stops it from working altogether.
Does anyone know how I can get the colormap to be preserved?

I don't know that much about embedded Linux, but the Linux kernel already
has NAT as a part of the TCP/IP stack, in the form of IP masquerading. If
that has been left intact in embedded Linux, then it's just a matter of
configuration (ipfwadm or ipchains, depending on the kernel version).

Hi,
I'm new to the kernel modules. I want to write a module (or device driver)
that
needs to have two threads of controls. I don't know what kernel routines are
available
for this purpose and how I can do the mutex like inter-locking in kernel
module.
I would appreciate e-mail response to [EMAIL PROTECTED]

Might as well put Microsoft on your right hand or forehead.
I cannot believe those guys. Did you know that Microsoft's ".NET" project is
nearly identical to a Netscape project in 1995 that was never finished
(probably due to Microsoft) called Costellation. Back then they were just
developing Windows 98. They are just a bunch of "has beens". Shove everyone in
the market around and steal other peoples ideas. Isn't that the worst type of
monopoly this country has ever seen? Innovation my ASS!! Whats up with the
crappy BIOs/IRQ architecture? You'd think they would develop something beyond
1970 technology there. All I see is a lucky man who got his OS (MS-DOS) on all
of IBM's PC's. And that was not even developed by him!!!
P.S. Internet Explorer was originally developed by Spry, Inc.

I believe that Internet Explorer was derived from a browser produced
by Spyglass Software. That browser, in turn was based on Mosaic.
So IE is another example of proprietizing free software.

However, the Vortex 2 sound card (Xitel Storm Platinum) isn't running. I

Is this the best sound card driver to try?

A) Cost is a function of quantity! Since you didn't post forecasts,
then you won't get costs, regardless of what chip you go with. Also,
you have to factor in the cost of the support chips, which will be
more than the price of the microprocessor.
B) Ease-of-design? You haven't stated what you are trying to design,
so how do you expect off-the-shelf solutions.
C) It remains to be determined if LINUX is the correct O/S for the
job. Have you considered ASICs or DSPs? Both may cost less in the
long run.
D) No insult meant, but by the nature of these questions, you aren't
ready to start asking for available designs, or even LINUX flavor
information. You haven't discussed quantities, but expect to know
pricing. You don't have a hardware design, which means you also don't
know power requirements, potential FCC certification issues,
reliability, and so on.
If it was me, I wouldn't worry about software now, and get somebody on
the team which can help with physical component design. Maybe talk to
a company that you can farm this out to.
Good Luck

Consider PPC 860 and PPC 8260. 860 is small real estate CPU, capable
of running off single RAM chip. 8260 has serial and ethernet on-chip.

Hmmm, it looks like a generational gap. The above author refered to "Business
Basic", and everybody and their dog is posting about "Visual Basic". BB was a
basic that was available first on Data General computers (RDOS and later AOS),
and then later the UNIX (tm) computers such as Fortune (which were ns32k based
if memory serves) mentioned above. I don't recall if the BB was done by the
same company, or if it was a clone of the DG version. If the company is still
around, I would imagine they probably have done a Linux port by now, but I
haven't kept track of them since I left Data General, 10+ years ago.
However, for new code, you probably would be better off using perl, since perl
has hooks to talk to various data bases. I don't know whether TCL/TK or Python
has such hooks. As somebody else said, look for the Perl CPAN that provides a
collection of various perl programs.

that is, of course, utter bullshit. first, web and email serving does NOT
qualify as "heavy load". they're both very easy, and no Unix would even
lose its breath under that kind of simple load. choosing Linux vs *BSD
is largely a matter of taste/religion/upbringing; there is certainly no
performance reason to choose netBSD over Linux.

Dear all,
Sorry for the last message I've posted. I'd provided insufficient
information about my problem.
My problem is I cannot compile simple I/O program. The error message came
out was:
In file included from try2.c:3:
/usr/include/asm/io.h:78: syntax error before `extern'
My codes was:
#include <stdio.h>
#include <unistd.h>
#include <asm/io.h>
#define BASEPORT 0x378 /* lp1 */
int main()
{
/* Get access to the ports */
if (ioperm(BASEPORT, 3, 1)) {perror("ioperm"); exit(1);}
/* Set the data signals (D0-7) of the port to all low (0) */
outb(0, BASEPORT);
/* Sleep for a while (100 ms) */
usleep(100000);
/* Read from the status port (BASE+1) and display the result */
printf("status: %d\n", inb(BASEPORT + 1));
/* We don't need the ports anymore */
if (ioperm(BASEPORT, 3, 0)) {perror("ioperm"); exit(1);}
exit(0);
}
My questions are:
What does it means "syntax error before 'extern'"?
And where I can find alternative io.h to replace it? probably my io.h got
problem.
Is there any online, Internet, sites provide the header files like io.h?
Thanks
