From ebe12d50064370e4ddec21a1e087b24295940319 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Fri, 12 Feb 2010 00:43:38 +0100 Subject: gallium: make max_anisotropy a unsigned bitfield member saves us a dword in sampler state, hw can't do non-integer aniso degree anyway. To allow aniso 1x (which seems of dubious value but some hardware (radeons) have such a mode, and even d3d allows specifiying it) redefine anisotropic filtering as disabled only if max_anistropy is 0. --- src/gallium/drivers/nv30/nv30_state.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/gallium/drivers/nv30/nv30_state.c') diff --git a/src/gallium/drivers/nv30/nv30_state.c b/src/gallium/drivers/nv30/nv30_state.c index 8fc6856ee5e..d911c807074 100644 --- a/src/gallium/drivers/nv30/nv30_state.c +++ b/src/gallium/drivers/nv30/nv30_state.c @@ -139,13 +139,13 @@ nv30_sampler_state_create(struct pipe_context *pipe, ps->en = 0; - if (cso->max_anisotropy >= 8.0) { + if (cso->max_anisotropy >= 8) { ps->en |= NV34TCL_TX_ENABLE_ANISO_8X; } else - if (cso->max_anisotropy >= 4.0) { + if (cso->max_anisotropy >= 4) { ps->en |= NV34TCL_TX_ENABLE_ANISO_4X; } else - if (cso->max_anisotropy >= 2.0) { + if (cso->max_anisotropy >= 2) { ps->en |= NV34TCL_TX_ENABLE_ANISO_2X; } -- cgit v1.2.3
