Hi all, I want to bring up this issue again on the mailing list, since it got lost in some irc chat a few days ago.
Deadwood came to the channel and noted that 25ee1f0e25195729f28b15f33d74db9ec6afd696 removes support for NOUVEAU_GEM_CPU_PREP_NOBLOCK in the kernel. This renders nouveau_bo_busy quite useless. Since nvfx depends on this function to avoid render serialization in the fragment shader code we should either revert the commit, or if there are valid reasons to remove the kernel support, rewrite the frag shader path in nvfx. Also radeon guys use some similar logic in their caching buffer manager to implement buffer reuse, which seems to be a possible worthwhile optimization for nvfx. Darktama, can you please comment on the reasons for the kernel change? -- lynxeye _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
