From e1a86bd6346b64a770839f446af07e4072ec2708 Mon Sep 17 00:00:00 2001 From: Jonathan Marek Date: Fri, 9 Aug 2019 10:41:22 -0400 Subject: [PATCH] etnaviv: blt: use only for tiling, and add missing formats * Removes the incorrect usage of translate_rs_format * Disables use of BLT engine for different src/dst format We only really need the BLT engine for tiling/detiling right now, but it would be nice to support as many blit cases as possible to avoid using PE for that. To deal with different formats we need to: * Have a translate_blt_format which has all supported formats * Fix the swizzle translation from gallium (current version was wrong) * Set the src/dst sRGB bits as needed * Find which type conversions the BLT engine can actually do Signed-off-by: Jonathan Marek Reviewed-by: Christian Gmeiner --- src/gallium/drivers/etnaviv/etnaviv_blt.c | 52 +++++++++++++---------- 1 file changed, 30 insertions(+), 22 deletions(-) diff --git a/src/gallium/drivers/etnaviv/etnaviv_blt.c b/src/gallium/drivers/etnaviv/etnaviv_blt.c index a90bb4609e5..c3e9da846f8 100644 --- a/src/gallium/drivers/etnaviv/etnaviv_blt.c +++ b/src/gallium/drivers/etnaviv/etnaviv_blt.c @@ -49,8 +49,21 @@ #include -/* Currently, used BLT formats overlap 100% with RS formats */ -#define translate_blt_format translate_rs_format +static uint32_t +etna_compatible_blt_format(enum pipe_format fmt) +{ + /* YUYV and UYVY are blocksize 4, but 2 bytes per pixel */ + if (fmt == PIPE_FORMAT_YUYV || fmt == PIPE_FORMAT_UYVY) + return BLT_FORMAT_R8G8; + + switch (util_format_get_blocksize(fmt)) { + case 1: return BLT_FORMAT_R8; + case 2: return BLT_FORMAT_R8G8; + case 4: return BLT_FORMAT_A8R8G8B8; + case 8: return BLT_FORMAT_A16R16G16B16; + default: return ETNA_NO_MATCH; + } +} static inline uint32_t blt_compute_stride_bits(const struct blt_imginfo *img) @@ -384,21 +397,20 @@ etna_try_blt_blit(struct pipe_context *pctx, return false; } - /* TODO: 1 byte per pixel formats aren't handled by etna_compatible_rs_format nor - * translate_rs_format. + /* Only support same format (used tiling/detiling) blits for now. + * TODO: figure out which different-format blits are possible and test them + * - need to use correct swizzle + * - set sRGB bits correctly + * - avoid trying to convert between float/int formats? */ - unsigned src_format = blit_info->src.format; - unsigned dst_format = blit_info->dst.format; + if (blit_info->src.format != blit_info->dst.format) + return false; - /* for a copy with same dst/src format, we can use a different format */ - if (translate_blt_format(src_format) == ETNA_NO_MATCH && - src_format == dst_format) { - src_format = dst_format = etna_compatible_rs_format(src_format); - } + uint32_t format = etna_compatible_blt_format(blit_info->dst.format); + if (format == ETNA_NO_MATCH) + return false; - if (translate_blt_format(src_format) == ETNA_NO_MATCH || - translate_blt_format(dst_format) == ETNA_NO_MATCH || - blit_info->scissor_enable || + if (blit_info->scissor_enable || blit_info->dst.box.depth != blit_info->src.box.depth || blit_info->dst.box.depth != 1) { return false; @@ -445,13 +457,11 @@ etna_try_blt_blit(struct pipe_context *pctx, op.src.addr.bo = src->bo; op.src.addr.offset = src_lev->offset + blit_info->src.box.z * src_lev->layer_stride; op.src.addr.flags = ETNA_RELOC_READ; - op.src.format = translate_blt_format(src_format); + op.src.format = format; op.src.stride = src_lev->stride; op.src.tiling = src->layout; - const struct util_format_description *src_format_desc = - util_format_description(src_format); for (unsigned x=0; x<4; ++x) - op.src.swizzle[x] = src_format_desc->swizzle[x]; + op.src.swizzle[x] = x; if (src_lev->ts_size && src_lev->ts_valid) { op.src.use_ts = 1; @@ -467,13 +477,11 @@ etna_try_blt_blit(struct pipe_context *pctx, op.dest.addr.bo = dst->bo; op.dest.addr.offset = dst_lev->offset + blit_info->dst.box.z * dst_lev->layer_stride; op.dest.addr.flags = ETNA_RELOC_WRITE; - op.dest.format = translate_blt_format(dst_format); + op.dest.format = format; op.dest.stride = dst_lev->stride; op.dest.tiling = dst->layout; - const struct util_format_description *dst_format_desc = - util_format_description(dst_format); for (unsigned x=0; x<4; ++x) - op.dest.swizzle[x] = dst_format_desc->swizzle[x]; + op.dest.swizzle[x] = x; op.dest_x = blit_info->dst.box.x; op.dest_y = blit_info->dst.box.y; -- 2.30.2
