From 2c29a6896a4a026ed3568db9caf90f422b711d8b Mon Sep 17 00:00:00 2001 From: Robert Ellison Date: Thu, 13 Nov 2008 11:22:12 -0700 Subject: CELL: fix stencil twiddling, stencil invert Many stencil tests were failing because of a failure to read the stencil buffer, due to "twiddling" (or "untwiddling") "an unsupported texture format". This is fixed for the case of a stencil/Z S824Z format (which twiddles just like the 32-bit color formats). tests/stencilwrap.c was failing on the GL_INVERT test, because the emitted code for "spe_xori" turned out not to be an actual "xori" instruction, but rather a "stqd" instruction, because of a typo in the rtasm code. This is now fixed, and tests/stencil_wrap now works. --- src/gallium/drivers/cell/ppu/cell_texture.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/gallium/drivers/cell') diff --git a/src/gallium/drivers/cell/ppu/cell_texture.c b/src/gallium/drivers/cell/ppu/cell_texture.c index ae88d06912..47cd9605c8 100644 --- a/src/gallium/drivers/cell/ppu/cell_texture.c +++ b/src/gallium/drivers/cell/ppu/cell_texture.c @@ -314,6 +314,7 @@ cell_twiddle_texture(struct pipe_screen *screen, switch (ct->base.format) { case PIPE_FORMAT_A8R8G8B8_UNORM: case PIPE_FORMAT_B8G8R8A8_UNORM: + case PIPE_FORMAT_S8Z24_UNORM: { int numFaces = ct->base.target == PIPE_TEXTURE_CUBE ? 6 : 1; int offset = bufWidth * bufHeight * 4 * surface->face; @@ -337,7 +338,7 @@ cell_twiddle_texture(struct pipe_screen *screen, } break; default: - printf("Cell: twiddle unsupported texture format\n"); + printf("Cell: twiddle unsupported texture format 0x%x\n", ct->base.format); ; } @@ -363,6 +364,7 @@ cell_untwiddle_texture(struct pipe_screen *screen, switch (ct->base.format) { case PIPE_FORMAT_A8R8G8B8_UNORM: case PIPE_FORMAT_B8G8R8A8_UNORM: + case PIPE_FORMAT_S8Z24_UNORM: { int numFaces = ct->base.target == PIPE_TEXTURE_CUBE ? 6 : 1; int offset = surface->stride * texHeight * 4 * surface->face; @@ -382,7 +384,7 @@ cell_untwiddle_texture(struct pipe_screen *screen, default: { ct->untiled_data[level] = NULL; - printf("Cell: untwiddle unsupported texture format\n"); + printf("Cell: untwiddle unsupported texture format 0x%x\n", ct->base.format); } } -- cgit v1.2.3
