This commit fixes offsets on Linear -> Tiled copies, corrects z pos fortiled->linear copies, corrects bytes_per_pixel calculation in tiled -> linear copies and relaxes some limitations set by latest dma fixes refactors. --- src/video_core/textures/decoders.cpp | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) (limited to 'src/video_core/textures/decoders.cpp') diff --git a/src/video_core/textures/decoders.cpp b/src/video_core/textures/decoders.cpp index 7e8295944..7df5f1452 100644 --- a/src/video_core/textures/decoders.cpp +++ b/src/video_core/textures/decoders.cpp @@ -257,19 +257,21 @@ std::vector UnswizzleTexture(u8* address, u32 tile_size_x, u32 tile_size_y, void SwizzleSubrect(u32 subrect_width, u32 subrect_height, u32 source_pitch, u32 swizzled_width, u32 bytes_per_pixel, u8* swizzled_data, u8* unswizzled_data, - u32 block_height_bit) { + u32 block_height_bit, u32 offset_x, u32 offset_y) { const u32 block_height = 1U << block_height_bit; const u32 image_width_in_gobs{(swizzled_width * bytes_per_pixel + (gob_size_x - 1)) / gob_size_x}; for (u32 line = 0; line < subrect_height; ++line) { + const u32 dst_y = line + offset_y; const u32 gob_address_y = - (line / (gob_size_y * block_height)) * gob_size * block_height * image_width_in_gobs + - ((line % (gob_size_y * block_height)) / gob_size_y) * gob_size; - const auto& table = legacy_swizzle_table[line % gob_size_y]; + (dst_y / (gob_size_y * block_height)) * gob_size * block_height * image_width_in_gobs + + ((dst_y % (gob_size_y * block_height)) / gob_size_y) * gob_size; + const auto& table = legacy_swizzle_table[dst_y % gob_size_y]; for (u32 x = 0; x < subrect_width; ++x) { + const u32 dst_x = x + offset_x; const u32 gob_address = - gob_address_y + (x * bytes_per_pixel / gob_size_x) * gob_size * block_height; - const u32 swizzled_offset = gob_address + table[(x * bytes_per_pixel) % gob_size_x]; + gob_address_y + (dst_x * bytes_per_pixel / gob_size_x) * gob_size * block_height; + const u32 swizzled_offset = gob_address + table[(dst_x * bytes_per_pixel) % gob_size_x]; u8* source_line = unswizzled_data + line * source_pitch + x * bytes_per_pixel; u8* dest_addr = swizzled_data + swizzled_offset; -- cgit v1.2.3
