From 6478a4de14d368bf85ba3477d73fd1bd91067e86 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 30 Nov 2010 23:28:43 +0100 Subject: r300g: fix texture swizzling with compressed textures on r400-r500 This fixes all S3TC piglit/texwrap tests. NOTE: This is a candidate for the 7.9 branch. --- src/gallium/drivers/r300/r300_chipset.c | 1 + src/gallium/drivers/r300/r300_chipset.h | 2 ++ src/gallium/drivers/r300/r300_reg.h | 2 +- src/gallium/drivers/r300/r300_state.c | 4 +++- src/gallium/drivers/r300/r300_state_derived.c | 9 +++++++-- src/gallium/drivers/r300/r300_texture.c | 17 ++++++++++------- src/gallium/drivers/r300/r300_texture.h | 6 ++++-- 7 files changed, 28 insertions(+), 13 deletions(-) (limited to 'src/gallium/drivers/r300') diff --git a/src/gallium/drivers/r300/r300_chipset.c b/src/gallium/drivers/r300/r300_chipset.c index 48c24092114..583e981a4d2 100644 --- a/src/gallium/drivers/r300/r300_chipset.c +++ b/src/gallium/drivers/r300/r300_chipset.c @@ -424,4 +424,5 @@ void r300_parse_chipset(struct r300_capabilities* caps) } caps->is_rv350 = caps->family >= CHIP_FAMILY_RV350; + caps->dxtc_swizzle = caps->is_r400 || caps->is_r500; } diff --git a/src/gallium/drivers/r300/r300_chipset.h b/src/gallium/drivers/r300/r300_chipset.h index e7ca642b4f3..7ea4175dbee 100644 --- a/src/gallium/drivers/r300/r300_chipset.h +++ b/src/gallium/drivers/r300/r300_chipset.h @@ -79,6 +79,8 @@ struct r300_capabilities { boolean is_r500; /* Whether or not the second pixel pipe is accessed with the high bit */ boolean high_second_pipe; + /* DXTC texture swizzling. */ + boolean dxtc_swizzle; }; /* Enumerations for legibility and telling which card we're running on. */ diff --git a/src/gallium/drivers/r300/r300_reg.h b/src/gallium/drivers/r300/r300_reg.h index 6bea783f697..788c513be75 100644 --- a/src/gallium/drivers/r300/r300_reg.h +++ b/src/gallium/drivers/r300/r300_reg.h @@ -1520,11 +1520,11 @@ USE OR OTHER DEALINGS IN THE SOFTWARE. # define R300_TX_TRI_PERF_3_8 (3<<15) # define R300_ANISO_THRESHOLD_MASK (7<<17) +# define R400_DXTC_SWIZZLE_ENABLE (1<<21) # define R500_MACRO_SWITCH (1<<22) # define R500_TX_MAX_ANISO(x) ((x) << 23) # define R500_TX_MAX_ANISO_MASK (63 << 23) # define R500_TX_ANISO_HIGH_QUALITY (1 << 30) - # define R500_BORDER_FIX (1<<31) #define R300_TX_FORMAT0_0 0x4480 diff --git a/src/gallium/drivers/r300/r300_state.c b/src/gallium/drivers/r300/r300_state.c index 247c22216e1..405b059d559 100644 --- a/src/gallium/drivers/r300/r300_state.c +++ b/src/gallium/drivers/r300/r300_state.c @@ -1347,6 +1347,7 @@ r300_create_sampler_view(struct pipe_context *pipe, struct r300_sampler_view *view = CALLOC_STRUCT(r300_sampler_view); struct r300_texture *tex = r300_texture(texture); boolean is_r500 = r300_screen(pipe->screen)->caps.is_r500; + boolean dxtc_swizzle = r300_screen(pipe->screen)->caps.dxtc_swizzle; if (view) { view->base = *templ; @@ -1363,7 +1364,8 @@ r300_create_sampler_view(struct pipe_context *pipe, view->format = tex->tx_format; view->format.format1 |= r300_translate_texformat(templ->format, view->swizzle, - is_r500); + is_r500, + dxtc_swizzle); if (is_r500) { view->format.format2 |= r500_tx_format_msb_bit(templ->format); } diff --git a/src/gallium/drivers/r300/r300_state_derived.c b/src/gallium/drivers/r300/r300_state_derived.c index c4cd291d75d..dc2d9ec66d7 100644 --- a/src/gallium/drivers/r300/r300_state_derived.c +++ b/src/gallium/drivers/r300/r300_state_derived.c @@ -764,13 +764,18 @@ static void r300_merge_textures_and_samplers(struct r300_context* r300) if (sampler->state.compare_mode == PIPE_TEX_COMPARE_NONE) { texstate->format.format1 |= r300_get_swizzle_combined(depth_swizzle, - view->swizzle); + view->swizzle, FALSE); } else { texstate->format.format1 |= - r300_get_swizzle_combined(depth_swizzle, 0); + r300_get_swizzle_combined(depth_swizzle, 0, FALSE); } } + if (r300->screen->caps.dxtc_swizzle && + util_format_is_compressed(tex->desc.b.b.format)) { + texstate->filter1 |= R400_DXTC_SWIZZLE_ENABLE; + } + /* to emulate 1D textures through 2D ones correctly */ if (tex->desc.b.b.target == PIPE_TEXTURE_1D) { texstate->filter0 &= ~R300_TX_WRAP_T_MASK; diff --git a/src/gallium/drivers/r300/r300_texture.c b/src/gallium/drivers/r300/r300_texture.c index cee56bccdcd..6c14e94e9c3 100644 --- a/src/gallium/drivers/r300/r300_texture.c +++ b/src/gallium/drivers/r300/r300_texture.c @@ -40,7 +40,8 @@ #include "pipe/p_screen.h" unsigned r300_get_swizzle_combined(const unsigned char *swizzle_format, - const unsigned char *swizzle_view) + const unsigned char *swizzle_view, + boolean dxtc_swizzle) { unsigned i; unsigned char swizzle[4]; @@ -51,10 +52,10 @@ unsigned r300_get_swizzle_combined(const unsigned char *swizzle_format, R300_TX_FORMAT_B_SHIFT, R300_TX_FORMAT_A_SHIFT }; - const uint32_t swizzle_bit[4] = { - R300_TX_FORMAT_X, + uint32_t swizzle_bit[4] = { + dxtc_swizzle ?
