Hi everyone!

for some days i have been trying to figure out why i can't allocate any
substantial amount of memory by using either the XvShmCreateImage or the
XShmCreateImage calls.

i am using freebsd 4.1-release with xfree-4.0.1 (i tried the package
first, then compiled xfree by hand just to be sure the port wasn't the
cause). my graphics card is a matrox g400 agp with 32mb of ram.

i can allocate 6 frames of memory at 720x576x16bpp on freebsd, while on a
test linux installation on the same box i can allocate nearly 100 of these
frames. the problem seems to be freebsd-related i figured. a friend of
mine reproduced the effect on another freebsd 4.1 box.

any hints/pointers are appreciated!

regards,

Heiko
