missing atyfb option in kernel 2.2.14pre9

missing atyfb option in kernel 2.2.14pre9

[Michael]

If I do 'make menuconfig' with the source from linuxcare.com.au version
2.2.14pre9, I can't select the atyfb driver, because there is no option
for this driver. Who has stolen this option ;-)

	I would appreciate it if the members of the list
would answer the following issue in detail, because
I'm intending to organize all Powerbook documentation
for www.linuxppc.org.  Thanks!

	I second that question, from a slightly different
angle.  I have been collecting the kernel source from
mirrors of the official kernel.org.  I get mine from
the SunSITE mirror on ftp.cdrom.com.  When I do either
'make menuconfig' or 'make xconfig', I notice that
under the "console" section, there are two entries for
"ATI Mach 64".  They are both identical, they're both
selected, and I cannot change their selections!
	This has been true with kernel versions 2.2.10,
2.2.12, 2.2.13, and 2.3.22.
	I have a Powerbook G3 Wallstreet series (May 1998)
and all development environment is from my stock
LinuxPPC R5 (not Q3) distribution.  Is it imperative
for me to upgrade to Q3?  I can do that.
	Thank you!

It is there. It used to be there twice, once in the list of standard PPC
video cards, and once in the list of experimental FB drivers. It is now
classified "experimental", so you see the option only if you choose
"Prompt for development and/or incomplete code/drivers" in the "General
setup" menu.

This is a different story from the above. In fact, I think in 'make
menuconfig' you *can* change the selections, only in 'make xconfig' it
doesn't work. But then I may not have the same kernel version as you. 

In any case, this has been a long-standing bug in the script files in
/usr/src/linux/scripts. It is fixed in the most recent kernels. If you
want to fix it in an older kernel version, either get the
/usr/src/linux/scripts directory from a more recent kernel or go to the
file drivers/video/Config.in and comment out all but one occurrence of
CONFIG_FB_ATY, in particular the one in an  'if [ "$ARCH" = "sparc64" ]'
clause. The latter one is responsible (together with the script bug)
that the selections are not changeable.

Ah, there is it. Up to now I don't select "Prompt for development and/or
incomplete code/drivers". I think this driver _is_ experimental. For
example scrolling in the console is much slower compared with the offb
driver and what is really annoying is that I can't use atyfb on my
PowerBook G3 (Wallstreet) if I boot it with Open Firmware.
