Joshua,
I am responding only because there is currently little sun driver
activity on the list, but I have been playing with some XF86/sun drivers
under Linux & Solaris. I am not an XF86 person, but I am willing to
pass on my experiences, for what they are worth. From here on, I
assume you have the XF86 source.
1. You can build a Solaris version of XF86, but the XF86 people
could not support it. What you have to do is:
a. In the config/cf directory, in the file <svr4.cf> you will see
that you don't get the XFree86 server under Solaris unless
the '( ...defined(BuildXFree86OnSparcSunOS))' succeeds. Make
it succeed, and for good measure "#define DoLoadableServer YES"
Just putting both in the first half of your site.def file works.
b. The solaris version you get unconditionally bombs because it
can't scan for PCI devices (i.e., it is basically unfinished).
In <xc/programs/Xserver/hw/xfree86/os-support/bus>, look at
'sparcPci.c,' and where the Solaris code just bombs with a fatal
error to the effect you have called "sparcPciCfgRead()," either
make it "return (CARD32) 0xffffffff;" or implement the function
under Solaris.
2. If you have set all the other site definitions you need, you
should now get a "clean" build of all of xfree86, set up to run
from wherever you set the ProjectRoot to. (Clean in quotes because
a few things, like xedit, don't build because of configuration
problems on xf86's part --- at least for me).
In any case, "make World" followed by "make install" should work.
3. Now, you are in unknown territory. Try "XFree86 -configure"; you
should get an initial guess at a usable XF86Config file. Look at
it, and look at the xf86 log file (in /var/log/X*.log) to see if
you are more or less satisfied. Your config file should have
somewhere in it a section with at least
Section "Device"
Identifier "some-card"
Driver "sunffb"
...
EndSection
and a corresponding "Screen" section tied to "some-card"
If not, you can always force a device section using "sunffb"
as just described and see what
XFree86 -probeonly -xf86config Your-test-config-file
says.
4. If you get this all working to your satisfaction, you "should"
be OK, but don't hold me to it.
5. You will notice that the sunffb driver you have built doesn't
know anything about screen blanking or DPMS (which is the only
reason that I even know what you are asking.) If you care, and
if what I have outlined otherwise seems to work, I can give you
a little source patch to the sunffb driver which lets it do
screen blanking and power management for a Creator3D/rev-3 with
a GDM-20E20, thanks to some pointers from David Miller, one of
the driver's authors.
6. By the way, XF86 does contain a version of Xsun24 which (under
linux, at least) supports your card and builds with no changes
as I described. Make sure that in your "sun.cf" file you have
defined
#define XSun24Server YES
#define XSunServer YES
and you should get those to play with as well.
I've told you probably more than I know; hope it's of some use.
Regards, Ferris
