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.

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! - */ - -#if 1 - -.macro pixman_composite_over_8888_0565_process_pixblock_tail_head - vqadd.u8 d16, d2, d20 - vld1.16 {d4, d5}, [DST_R, :128]! - vqadd.u8 q9, q0, q11 - vshrn.u16 d6, q2, #8 - fetch_src_pixblock - vshrn.u16 d7, q2, #3 - vsli.u16 q2, q2, #5 - vshll.u8 q14, d16, #8 - PF add PF_X, PF_X, #8 - vshll.u8 q8, d19, #8 - PF tst PF_CTL, #0xF - vsri.u8 d6, d6, #5 - PF addne PF_X, PF_X, #8 - vmvn.8 d3, d3 - PF subne PF_CTL, PF_CTL, #1 - vsri.u8 d7, d7, #6 - vshrn.u16 d30, q2, #2 - vmull.u8 q10, d3, d6 - PF pld, [PF_SRC, PF_X, lsl #src_bpp_shift] - vmull.u8 q11, d3, d7 - vmull.u8 q12, d3, d30 - PF pld, [PF_DST, PF_X, lsl #dst_bpp_shift] - vsri.u16 q14, q8, #5 - PF cmp PF_X, ORIG_W - vshll.u8 q9, d18, #8 - vrshr.u16 q13, q10, #8 - PF subge PF_X, PF_X, ORIG_W - vrshr.u16 q3, q11, #8 - vrshr.u16 q15, q12, #8 - PF subges PF_CTL, PF_CTL, #0x10 - vsri.u16 q14, q9, #11 - PF ldrgeb DUMMY, [PF_SRC, SRC_STRIDE, lsl #src_bpp_shift]! - vraddhn.u16 d20, q10, q13 - vraddhn.u16 d23, q11, q3 - PF ldrgeb DUMMY, [PF_DST, DST_STRIDE, lsl #dst_bpp_shift]! - vraddhn.u16 d22, q12, q15 - vst1.16 {d28, d29}, [DST_W, :128]! -.endm - -#else - -/* If we did not care much about the performance, we would just use this... */ -.macro pixman_composite_over_8888_0565_process_pixblock_tail_head - pixman_composite_over_8888_0565_process_pixblock_tail - vst1.16 {d28, d29}, [DST_W, :128]! - vld1.16 {d4, d5}, [DST_R, :128]! - fetch_src_pixblock - pixman_composite_over_8888_0565_process_pixblock_head - cache_preload 8, 8 -.endm - -#endif - -/* - * And now the final part.

+ * 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
+ * like d8-d15 or do anything else) followed by
+ * 'pixman_composite_over_8888_0565_process_pixblock_head',
+ * 'pixman_composite_over_8888_0565_process_pixblock_tail' and
+ * 'pixman_composite_over_8888_0565_process_pixblock_tail_head'
+ * which we got implemented above.
+ *
+ * The last part is the NEON registers allocation scheme.
