SubjectProblem compiling 'setup.S' in 1.3.86+
Date
Hello, all.  Just ran into a problem in attempting to compile the last few
Linux kernels. Here's the log from the end of the 'make zImage':


gcc -D__KERNEL__ -I/usr/src/linux-1.3.88/include -E -D__ELF__ -traditional -DSVGA_MODE=NORMAL_VGA setup.S -o setup.s

make: *** [zImage] Error 2

I was able to successfully compile 1.3.85 but not 1.3.86 or 1.3.88. I noticed
that 'outidx' appeared to be defined in video.S. And I've been applying the
following patch to my kernel source to get rid of as much of the video code as
possible.

! Enable autodetection of SVGA adapters and modes

+#undef CONFIG_VIDEO_SVGA

! Enable autodetection of VESA modes
-#define CONFIG_VIDEO_VESA
+#undef CONFIG_VIDEO_VESA

! Enable compacting of mode table
#define CONFIG_VIDEO_COMPACT

So it appears that 'setup.S' depends on CONFIG_VIDEO_SVGA being defined. Which
seems flawed, IMHO. While we're on the subject, _WHY_ is all this damned video
code in the kernel in the first place?!?! I boot up in normal 80x25 mode, and
then use SVGATextMode to switch to 100x37. SVGATextMode is a perfectly good
user-mode program for doing this. I really fail to see the point in including
page after page of code in 'video.S' to detect and set modes for every video
card on the planet. At the LEAST, there should be a compile-time option to get
rid of this unnecessary code bloat. It'd be nice if patches like the above
were not necessary.
