From c5b8ba9368fe935af9f350874f3c03f5a230d4b5 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sat, 28 Aug 2010 07:54:36 +0200 Subject: r300g: fix blitting between 2D NPOT mipmaps Even though MIP filtering is not supported, we can bind an arbitrary mipmap as the zero mipmap level. NPOT textures now follow GL_TEXTURE_BASE_LEVEL and GL_TEXTURE_MIN_LOD. This fixes piglit/fbo-copyteximage. --- src/gallium/drivers/r300/r300_texture.c | 43 +++++++++++++++++++-------------- 1 file changed, 25 insertions(+), 18 deletions(-) (limited to 'src/gallium/drivers/r300/r300_texture.c') diff --git a/src/gallium/drivers/r300/r300_texture.c b/src/gallium/drivers/r300/r300_texture.c index 852acdd462..66f6d80bd0 100644 --- a/src/gallium/drivers/r300/r300_texture.c +++ b/src/gallium/drivers/r300/r300_texture.c @@ -541,48 +541,55 @@ boolean r300_is_sampler_format_supported(enum pipe_format format) return r300_translate_texformat(format, 0, TRUE) != ~0; } -static void r300_texture_setup_immutable_state(struct r300_screen* screen, - struct r300_texture* tex) +void r300_texture_setup_format_state(struct r300_screen *screen, + struct r300_texture_desc *desc, + unsigned level, + struct r300_texture_format_state *out) { - struct r300_texture_format_state* f = &tex->tx_format; - struct pipe_resource *pt = &tex->desc.b.b; + struct pipe_resource *pt = &desc->b.b; boolean is_r500 = screen->caps.is_r500; + /* Mask out all the fields we change. */ + out->format0 = 0; + out->format1 &= ~R300_TX_FORMAT_TEX_COORD_TYPE_MASK; + out->format2 &= R500_TXFORMAT_MSB; + out->tile_config = 0; + /* Set sampler state. */ - f->format0 = R300_TX_WIDTH((pt->width0 - 1) & 0x7ff) | - R300_TX_HEIGHT((pt->height0 - 1) & 0x7ff); + out->format0 = R300_TX_WIDTH((u_minify(pt->width0, level) - 1) & 0x7ff) | + R300_TX_HEIGHT((u_minify(pt->height0, level) - 1) & 0x7ff); - if (tex->desc.uses_stride_addressing) { + if (desc->uses_stride_addressing) { /* rectangles love this */ - f->format0 |= R300_TX_PITCH_EN; - f->format2 = (tex->desc.stride_in_pixels[0] - 1) & 0x1fff; + out->format0 |= R300_TX_PITCH_EN; + out->format2 = (desc->stride_in_pixels[level] - 1) & 0x1fff; } else { /* Power of two textures (3D, mipmaps, and no pitch), * also NPOT textures with a width being POT. */ - f->format0 |= R300_TX_DEPTH(util_logbase2(pt->depth0) & 0xf); + out->format0 |= + R300_TX_DEPTH(util_logbase2(u_minify(pt->depth0, level)) & 0xf); } - f->format1 = 0; if (pt->target == PIPE_TEXTURE_CUBE) { - f->format1 |= R300_TX_FORMAT_CUBIC_MAP; + out->format1 |= R300_TX_FORMAT_CUBIC_MAP; } if (pt->target == PIPE_TEXTURE_3D) { - f->format1 |= R300_TX_FORMAT_3D; + out->format1 |= R300_TX_FORMAT_3D; } /* large textures on r500 */ if (is_r500) { if (pt->width0 > 2048) { - f->format2 |= R500_TXWIDTH_BIT11; + out->format2 |= R500_TXWIDTH_BIT11; } if (pt->height0 > 2048) { - f->format2 |= R500_TXHEIGHT_BIT11; + out->format2 |= R500_TXHEIGHT_BIT11; } } - f->tile_config = R300_TXO_MACRO_TILE(tex->desc.macrotile[0]) | - R300_TXO_MICRO_TILE(tex->desc.microtile); + out->tile_config = R300_TXO_MACRO_TILE(desc->macrotile[level]) | + R300_TXO_MICRO_TILE(desc->microtile); } static void r300_texture_setup_fb_state(struct r300_screen* screen, @@ -716,7 +723,7 @@ r300_texture_create_object(struct r300_screen *rscreen, return NULL; } /* Initialize the hardware state. */ - r300_texture_setup_immutable_state(rscreen, tex); + r300_texture_setup_format_state(rscreen, &tex->desc, 0, &tex->tx_format); r300_texture_setup_fb_state(rscreen, tex); tex->desc.b.vtbl = &r300_texture_vtbl; -- cgit v1.2.3
