We need to be good about catching this on review for new stuff. For older stuff I think there was a bit of momentum awhile back, but it seems to have dissipated. We could try to extract it from kernel source somehow, but for user API stuff, I think we really want man pages in libdrm, in addition to whatever web based documentation we make available. -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
