Subject: radv/gfx10: enable NGG_WAVE_ID_EN for NGG streamout
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2d89d8f33359eb517f9e1b4b81f2fddbe47ddfa3;p=mesa.git

radv/gfx10: enable NGG_WAVE_ID_EN for NGG streamout

Otherwise the wave IDs are probably 0 and it hangs. NGG_WAVE_ID_EN
generates wave IDs for GDS OA.
