Fix for glint_drv.so found, all release versions of driver do work now.
It was a typical endianess issue.
See
Xorg_alanc/X-src-20070227__20070401sun/X-src-20070227/XW_NV/open-src/xserver/xorg/xorg-server-1.2.0/hw/xfree86/common/compiler.h

So
# if defined(SPARC_MMIO_IS_BE) /* No byteswapping */
needs to evaluate to true.
Here is a working Makefile fix for glint (for MSB ppc and sparc) :
CPPFLAGS+= -DPPC_MMIO_IS_BE -DSPARC_MMIO_IS_BE
btw, I purchased a few more (so far unsupported/untested) frame buffers, which
will arrive soon:
Two items XVR-1000 (ffb3 with the java cpu)
Expert 3d
Expert 3d lite
XVR-500
XVR-600
TurboGX, TurboGXPlus (they just arrived yesterday, so I can actually test our
cg6 driver now)
~m
p.s. I do include your patched wsfb_drv.so now [both patches], but in a
location where it is not found by default, it now gets installed to
/export/home/bochnig/projects/Xorg_alanc/X-src-20070227__20070401sun/X-src-20070227/XW_NV/proto-sun4-svr4/usr/X11/lib/modules/drivers/opensolaris/wsfb_drv.so
(so that it doesn't affect the native drivers during bus scanning by default,
but is still available for testing and can be symlinked-over for that purpose)
I'm also doing exactly the same with vesa_drv.so and vga_drv.so, which
currently don't fully work with any card on sparc, but maybe we can get them
flirting with the wildcat chipsets some day, at least the VESA driver ... ??
