Author: Eric Anholt <e...@anholt.net> Date: Mon Aug 18 12:46:24 2014 -0700 vc4: Fix viewport handling in the uniforms upload. I had the right viewports in vc4_emit.c, but grabbed the wrong values in the uniform setup, so primitives would claim to be in the wrong parts of the screen. (The vc4_emit.c state looks like it just decides how big the clipping guardband is). This gets fbo-viewport closer to working (which still has the problem that the HW is always guard-band clipping), and fixes inverted FBO rendering in general. --- src/gallium/drivers/vc4/vc4_program.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/src/gallium/drivers/vc4/vc4_program.c b/src/gallium/drivers/vc4/vc4_program.c index 24f7620..f7791ab 100644 --- a/src/gallium/drivers/vc4/vc4_program.c +++ b/src/gallium/drivers/vc4/vc4_program.c @@ -1474,12 +1474,10 @@ vc4_write_uniforms(struct vc4_context *vc4, struct vc4_compiled_shader *shader, gallium_uniforms[uinfo->data[i]]); break; case QUNIFORM_VIEWPORT_X_SCALE: - cl_f(&vc4->uniforms, - vc4->framebuffer.width * 16.0f / 2.0f); + cl_f(&vc4->uniforms, vc4->viewport.scale[0] * 16.0f); break; case QUNIFORM_VIEWPORT_Y_SCALE: - cl_f(&vc4->uniforms, - vc4->framebuffer.height * -16.0f / 2.0f); + cl_f(&vc4->uniforms, vc4->viewport.scale[1] * 16.0f); break; case QUNIFORM_VIEWPORT_Z_OFFSET: _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-commit
