Cool. I have a similar machine, the 500SX which also has PGX64. You do not need wsfb for it, as wsfb lacks hardware accelleration and only seems to work in 8bit mode as of this writing. We can use the ati driver(s) for the actual graphics chip. The only issue had been the scanning through the pci bus on my SPARCle 500SX (Hummingbird or Simba, if I remember correctly), but I didn't yet test the current new Xorg, as I still had Solaris 10 03/05 on my Laptop. I'm currently backing up my SPARCle's hdd and will perform an upgrade to snv62 now. I'm doing the same with my Ultra80 (which has a Creator 3D inside, plus a PGX32). I'm impatiently looking forward to seeing, whether or not it works now (the laptop). I also have way more experience now, and I'm confident we will have it working rather soon. In TrueColor and accellerated, of course. > I remember > talking to Alan on IRC and hearing that 'wsfb' can > only do 8-bit color. > Maybe I'll get a chance to dig through the code soon > and learn the ioctl's > for the framebuffer. We don't have to deal with ioctl()'s too much, as the important thing are the userland modules in /usr/X11/lib/modules/drivers, so we can mostly live without them, as they are rather a limiting factor sometimes. > In any case, Martin, if you need > me to test any code, > I'll be glad to (I've got a PGX64 and an Elite3D).

Yes, I also have a TupboGX and a TurboGXPlus here now. The cg6 driver is already included in my binary release (Xorg's cg6 module), but I need to perform cg6 testing before I can list them as supported. My Ultra2 is in parts currently. The src you mentioned is very important as reference, for /dev/fb. I need to switch into personal "cg6 mode". Good to know, you are listening and interested. > I don't have a lot of > experience writing > drivers, let alone framebuffer drivers for Solaris, > and I think a > reference document detailing a framebuffer > implementation would be a huge > help in my efforts. Same here. Just hacking a bit. Developing such a driver would be a different story. Regards, Martin Bochnig http://www.martux.org/marTux___OSDevCon2007.pdf This message posted from opensolaris.org
