CVSROOT: /cvsroot/dri Module name: xc Repository: xc/xc/lib/GL/mesa/src/drv/r128/ Changes by: idr@sc8-pr-cvs1. 02/11/27 12:47:44Log message: Initial pass at adding texmem support to Rage128 driver. These changes have not yet been tested as I don't have access to Rage128 hardware. I will post to dri-devel to beg for help.
I fixed one trivial problem with turning on extensions (is that *strictly* a texmem change, Ian?)
Now I've got this:
Program received signal SIGSEGV, Segmentation fault.
0x4047258c in driInitTextureObjects (ctx=0x8056b18, swapped=0x8054e00,
targets=3) at texmem.c:802
802 move_to_tail( swapped, (driTextureObject *) texObj->DriverData );
(gdb) print swapped
$1 = (driTextureObject *) 0x8054e00
(gdb) print *swapped
$2 = {next = 0x8054e00, prev = 0x8054e00, heap = 0x0, tObj = 0x0,
memBlock = 0x0, bound = 0, totalSize = 0, dirty_images = {0, 0, 0, 0, 0, 0}}
(gdb) print texObj->DriverData
$3 = (void *) 0x0
It seems to be during initialization:

I'll have a look & find out more.
