Hi!
Currently I have added this to radeon_drm_winsys.c:
385 if (ws->gen =3D=3D DRV_R300) {
386 if (!radeon_get_drm_value(ws->fd, RADEON_INFO_NUM_GB_PIPES,
387 "GB pipe count",
388 &ws->info.r300_num_gb_pipes))
389 return false;
390 + // FIXME: only works for my own setup (prenex):
391 + ws->info.r300_num_gb_pipes=3D1;
Now I have no problems so far. It can be that HyperZ code is just good as-i=
s,
but for some resoun the radeon_get_drm_value returns a bad gb_pipes number.
Currently testing with this a bit more throughly before moving further, but
everything seems to work so far, just this is not a proper fix.
Some questions I can have:
1.) Is there any way to ensure how many pipes a card has? One pipeline seem=
s to
be really few for a GPU, but this is a mobile integrated card.
2.) Can the other indicated pipes be existing on my card but turned off for
some reason?
3.) radeon_get_drm_value - is this in the kernel source tree? I will have a
look later on the code behind it.
