From b70a47736ad42bf10a9d6d051204fb140c1c67e8 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Fri, 20 May 2005 18:40:11 +0000 Subject: [PATCH] Add support for modes with a depth-buffer but no stencil-buffer. This eliminates various "3D driver claims to not support visual" messages in 16-bit color mode. --- src/mesa/drivers/dri/i915/intel_screen.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/src/mesa/drivers/dri/i915/intel_screen.c b/src/mesa/drivers/dri/i915/intel_screen.c index 082c36b..a73137f 100644 --- a/src/mesa/drivers/dri/i915/intel_screen.c +++ b/src/mesa/drivers/dri/i915/intel_screen.c @@ -405,28 +405,30 @@ intelFillInModes( unsigned pixel_bits, unsigned depth_bits, GLenum fb_format; GLenum fb_type; - /* GLX_SWAP_COPY_OML is only supported because the MGA driver doesn't + /* GLX_SWAP_COPY_OML is only supported because the Intel driver doesn't * support pageflipping at all. */ static const GLenum back_buffer_modes[] = { GLX_NONE, GLX_SWAP_UNDEFINED_OML, GLX_SWAP_COPY_OML }; - u_int8_t depth_bits_array[2]; - u_int8_t stencil_bits_array[2]; + u_int8_t depth_bits_array[3]; + u_int8_t stencil_bits_array[3]; depth_bits_array[0] = 0; depth_bits_array[1] = depth_bits; + depth_bits_array[2] = depth_bits; /* Just like with the accumulation buffer, always provide some modes * with a stencil buffer.
