X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=50eed4eed5d81cdf190d257506d36c5c23d4ce3b;p=mesa.git i965: Pretend we don't support BRW_SURFACEFORMAT_R16G16B16_FLOAT for textures. None of the other 3-component 16bpc formats are directly supported, so they get promoted to XRGB equivalents. *Not* promoting RGB16F the same way makes texture views much more fiddly -- we don't want to have to do crazy copying behind the scenes. (with my other master + my experimental ARB_texture_view support) fixes the piglit test: `spec/ARB_texture_view/view compare 48bit formats` No regressions in gpu.tests on Haswell. V4: Don't alter the formats table -- just don't match it to a mesa_format.
