- * Implementation of pixman_composite_over_8888_0565_asm_neon
- *
- * This function takes a8r8g8b8 source buffer, r5g6b5 destination buffer and
- * performs OVER compositing operation. Function fast_composite_over_8888_0565
- * from pixman-fast-path.c does the same in C and can be used as a reference.
- *
- * First we need to have some NEON assembly code which can do the actual
- * operation on the pixels and provide it to the template macro.
- *
- * Template macro quite conveniently takes care of emitting all the necessary
- * code for memory reading and writing (including quite tricky cases of
- * handling unaligned leading/trailing pixels), so we only need to deal with
- * the data in NEON registers.
- *
- * NEON registers allocation in general is recommented to be the following:
- * d0, d1, d2, d3 - contain loaded source pixel data
- * d4, d5, d6, d7 - contain loaded destination pixels (if they are needed)
- * d24, d25, d26, d27 - contain loading mask pixel data (if mask is used)
- * d28, d29, d30, d31 - place for storing the result (destination pixels)
- *
- * As can be seen above, four 64-bit NEON registers are used for keeping
- * intermediate pixel data and up to 8 pixels can be processed in one step
- * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp).
- *
- * This particular function uses the following registers allocation:
- * d0, d1, d2, d3 - contain loaded source pixel data
- * d4, d5 - contain loaded destination pixels (they are needed)
- * d28, d29 - place for storing the result (destination pixels)
- */
-
-/*
- * Step one. We need to have some code to do some arithmetics on pixel data.
- * This is implemented as a pair of macros: '*_head' and '*_tail'. When used
- * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5},
- * perform all the needed calculations and write the result to {d28, d29}.
- * The rationale for having two macros and not just one will be explained
- * later. In practice, any single monolitic function which does the work can
- * be split into two parts in any arbitrary way without affecting correctness.
- *
- * There is one special trick here too. Common template macro can optionally
- * make our life a bit easier by doing R, G, B, A color components
- * deinterleaving for 32bpp pixel formats (and this feature is used in
- * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that
- * instead of having 8 packed pixels in {d0, d1, d2, d3} registers, we
- * actually use d0 register for blue channel (a vector of eight 8-bit
- * values), d1 register for green, d2 for red and d3 for alpha. This
- * simple conversion can be also done with a few NEON instructions:
- *
- * Packed to planar conversion:
- * vuzp.8 d0, d1
- * vuzp.8 d2, d3
- * vuzp.8 d1, d3
- * vuzp.8 d0, d2
- *
- * Planar to packed conversion:
- * vzip.8 d0, d2
- * vzip.8 d1, d3
- * vzip.8 d2, d3
- * vzip.8 d0, d1
- *
- * But pixel can be loaded directly in planar format using VLD4.8 NEON
- * instruction. It is 1 cycle slower than VLD1.32, so this is not always
- * desirable, that's why deinterleaving is optional.
- *
- * But anyway, here is the code:

-/*
- * OK, now we got almost everything that we need. Using the above two
- * macros, the work can be done right. But now we want to optimize
- * it a bit. ARM Cortex-A8 is an in-order core, and benefits really
- * a lot from good code scheduling and software pipelining.
- *
- * Let's construct some code, which will run in the core main loop.
- * Some pseudo-code of the main loop will look like this:
- * head
- * while (...) {
- * tail
- * head
- * }
- * tail
- *
- * It may look a bit weird, but this setup allows to hide instruction
- * latencies better and also utilize dual-issue capability more
- * efficiently (make pairs of load-store and ALU instructions).
- *
- * So what we need now is a '*_tail_head' macro, which will be used
- * in the core main loop. A trivial straightforward implementation
- * of this macro would look like this:
- *
- * pixman_composite_over_8888_0565_process_pixblock_tail
- * vst1.16 {d28, d29}, [DST_W, :128]!
- * vld1.16 {d4, d5}, [DST_R, :128]!
- * vld4.32 {d0, d1, d2, d3}, [SRC]!
- * pixman_composite_over_8888_0565_process_pixblock_head
- * cache_preload 8, 8
- *
- * Now it also got some VLD/VST instructions. We simply can't move from
- * processing one block of pixels to the other one with just arithmetics.
- * The previously processed data needs to be written to memory and new
- * data needs to be fetched. Fortunately, this main loop does not deal
- * with partial leading/trailing pixels and can load/store a full block
- * of pixels in a bulk. Additionally, destination buffer is already
- * 16 bytes aligned here (which is good for performance).
- *
- * New things here are DST_R, DST_W, SRC and MASK identifiers. These
- * are the aliases for ARM registers which are used as pointers for
- * accessing data. We maintain separate pointers for reading and writing
- * destination buffer (DST_R and DST_W).
- *
- * Another new thing is 'cache_preload' macro. It is used for prefetching
- * data into CPU L2 cache and improve performance when dealing with large
- * images which are far larger than cache size. It uses one argument
- * (actually two, but they need to be the same here) - number of pixels
- * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some
- * details about this macro. Moreover, if good performance is needed
- * the code from this macro needs to be copied into '*_tail_head' macro
- * and mixed with the rest of code for optimal instructions scheduling.
- * We are actually doing it below.
- *
- * Now after all the explanations, here is the optimized code.
- * Different instruction streams (originaling from '*_head', '*_tail'
- * and 'cache_preload' macro) use different indentation levels for
- * better readability. Actually taking the code from one of these
- * indentation levels and ignoring a few VLD/VST instructions would
- * result in exactly the code from '*_head', '*_tail' or 'cache_preload'
- * macro!

- * And now the final part. We are using 'generate_composite_function' macro
- * to put all the stuff together. We are specifying the name of the function
- * which we want to get, number of bits per pixel for the source, mask and
- * destination (0 if unused, like mask in this case). Next come some bit
- * flags:
- * FLAG_DST_READWRITE - tells that the destination buffer is both read
- * and written, for write-only buffer we would use
- * FLAG_DST_WRITEONLY flag instead
- * FLAG_DEINTERLEAVE_32BPP - tells that we prefer to work with planar data
- * and separate color channels for 32bpp format.
- * The next things are:
- * - the number of pixels processed per iteration (8 in this case, because
- * that's the maximum what can fit into four 64-bit NEON registers).
- * - prefetch distance, measured in pixel blocks. In this case it is 5 times
- * by 8 pixels. That would be 40 pixels, or up to 160 bytes. Optimal
- * prefetch distance can be selected by running some benchmarks.
- *
- * After that we specify some macros, these are 'default_init',
- * 'default_cleanup' here which are empty (but it is possible to have custom
- * init/cleanup macros to be able to save/restore some extra NEON registers

In practice, any single monolitic function which does the work can + * be split into two parts in any arbitrary way without affecting correctness. + * + * There is one special trick here too.

This + * simple conversion can be also done with a few NEON instructions: + * + * Packed to planar conversion: + * vuzp.8 d0, d1 + * vuzp.8 d2, d3 + * vuzp.8 d1, d3 + * vuzp.8 d0, d2 + * + * Planar to packed conversion: + * vzip.8 d0, d2 + * vzip.8 d1, d3 + * vzip.8 d2, d3 + * vzip.8 d0, d1 + * + * But pixel can be loaded directly in planar format using VLD4.8 NEON + * instruction.

ARM Cortex-A8 is an in-order core, and benefits really + * a lot from good code scheduling and software pipelining. + * + * Let's construct some code, which will run in the core main loop. + * Some pseudo-code of the main loop will look like this: + * head + * while (...) { + * tail + * head + * } + * tail + * + * It may look a bit weird, but this setup allows to hide instruction + * latencies better and also utilize dual-issue capability more + * efficiently (make pairs of load-store and ALU instructions). + * + * So what we need now is a '*_tail_head' macro, which will be used + * in the core main loop.

We simply can't move from + * processing one block of pixels to the other one with just arithmetics. + * The previously processed data needs to be written to memory and new + * data needs to be fetched. Fortunately, this main loop does not deal + * with partial leading/trailing pixels and can load/store a full block + * of pixels in a bulk. Additionally, destination buffer is already + * 16 bytes aligned here (which is good for performance). + * + * New things here are DST_R, DST_W, SRC and MASK identifiers. These + * are the aliases for ARM registers which are used as pointers for + * accessing data. We maintain separate pointers for reading and writing + * destination buffer (DST_R and DST_W). + * + * Another new thing is 'cache_preload' macro. It is used for prefetching + * data into CPU L2 cache and improve performance when dealing with large + * images which are far larger than cache size. It uses one argument + * (actually two, but they need to be the same here) - number of pixels + * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some + * details about this macro. Moreover, if good performance is needed + * the code from this macro needs to be copied into '*_tail_head' macro + * and mixed with the rest of code for optimal instructions scheduling. + * We are actually doing it below. + * + * Now after all the explanations, here is the optimized code. + * Different instruction streams (originaling from '*_head', '*_tail' + * and 'cache_preload' macro) use different indentation levels for + * better readability.
