The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/src/pixman/Makefile.am b/src/pixman/Makefile.am new file mode 100644 index 0000000..5137c9e --- /dev/null +++ b/src/pixman/Makefile.am @@ -0,0 +1,137 @@ +SUBDIRS = pixman demos test + +pkgconfigdir=$(libdir)/pkgconfig +pkgconfig_DATA=pixman-1.pc + +$(pkgconfig_DATA): pixman-1.pc.in + +snapshot: + distdir="$(distdir)-`date '+%Y%m%d'`"; \ + test -d "$(srcdir)/.git" && distdir=$$distdir-`cd "$(srcdir)" && git rev-parse HEAD | cut -c 1-6`; \ + $(MAKE) $(AM_MAKEFLAGS) distdir="$$distdir" dist + +GPGKEY=3892336E +USERNAME=$$USER +RELEASE_OR_SNAPSHOT = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo release; else echo snapshot; fi) +RELEASE_CAIRO_HOST = $(USERNAME)@cairographics.org +RELEASE_CAIRO_DIR = /srv/cairo.freedesktop.org/www/$(RELEASE_OR_SNAPSHOT)s +RELEASE_CAIRO_URL = http://cairographics.org/$(RELEASE_OR_SNAPSHOT)s +RELEASE_XORG_URL = http://xorg.freedesktop.org/archive/individual/lib +RELEASE_XORG_HOST = $(USERNAME)@xorg.freedesktop.org +RELEASE_XORG_DIR = /srv/xorg.freedesktop.org/archive/individual/lib +RELEASE_ANNOUNCE_LIST = cairo-announce@cairographics.org, xorg-announce@lists.freedesktop.org, pixman@lists.freedesktop.org + +EXTRA_DIST = \ + Makefile.win32 \ + Makefile.win32.common + +tar_gz = $(PACKAGE)-$(VERSION).tar.gz +tar_bz2 = $(PACKAGE)-$(VERSION).tar.bz2 + +sha1_tgz = $(tar_gz).sha1 +md5_tgz = $(tar_gz).md5 + +sha1_tbz2 = $(tar_bz2).sha1 +md5_tbz2 = $(tar_bz2).md5 + +gpg_file = $(sha1_tgz).asc + +$(sha1_tgz): $(tar_gz) + sha1sum $^ > $@ + +$(md5_tgz): $(tar_gz) + md5sum $^ > $@ + +$(sha1_tbz2): $(tar_bz2) + sha1sum $^ > $@ + +$(md5_tbz2): $(tar_bz2) + md5sum $^ > $@ + +$(gpg_file): $(sha1_tgz) + @echo "Please enter your GPG password to sign the checksum." + gpg --armor --sign $^ + +HASHFILES = $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(md5_tbz2) + +release-verify-newer: + @echo -n "Checking that no $(VERSION) release already exists at $(RELEASE_XORG_HOST)..." + @ssh $(RELEASE_XORG_HOST) test ! -e $(RELEASE_XORG_DIR)/$(tar_gz) \ + || (echo "Ouch." && echo "Found: $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR)/$(tar_gz)" \ + && echo "Refusing to try to generate a new release of the same name." \ + && false) + @ssh $(RELEASE_CAIRO_HOST) test ! -e $(RELEASE_CAIRO_DIR)/$(tar_gz) \ + || (echo "Ouch." && echo "Found: $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR)/$(tar_gz)" \ + && echo "Refusing to try to generate a new release of the same name." \ + && false) + @echo "Good." + +release-remove-old: + $(RM) $(tar_gz) $(tar_bz2) $(HASHFILES) $(gpg_file) + +ensure-prev: + @if [[ "$(PREV)" == "" ]]; then \ + echo "" && \ + echo "You must set the PREV variable on the make command line to" && \ + echo "the last version." && \ + echo "" && \ + echo "For example:" && \ + echo " make PREV=0.7.3" && \ + echo "" && \ + false; \ + fi + +release-check: ensure-prev release-verify-newer release-remove-old distcheck + +release-tag: + git tag -u $(GPGKEY) -m "$(PACKAGE) $(VERSION) release" $(PACKAGE)-$(VERSION) + +release-upload: release-check $(tar_gz) $(tar_bz2) $(sha1_tgz) $(sha1_tbz2) $(md5_tgz) $(gpg_file) + scp $(tar_gz) $(sha1_tgz) $(gpg_file) $(RELEASE_CAIRO_HOST):$(RELEASE_CAIRO_DIR) + scp $(tar_gz) $(tar_bz2) $(RELEASE_XORG_HOST):$(RELEASE_XORG_DIR) + ssh $(RELEASE_CAIRO_HOST) "rm -f $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-[0-9]* && ln -s $(tar_gz) $(RELEASE_CAIRO_DIR)/LATEST-$(PACKAGE)-$(VERSION)" + +RELEASE_TYPE = $$(if test "x$(PIXMAN_VERSION_MINOR)" = "x$$(echo "$(PIXMAN_VERSION_MINOR)/2*2" | bc)" ; then echo "stable release in the" ; else echo "development snapshot leading up to a stable"; fi) + +release-publish-message: $(HASHFILES) ensure-prev + @echo "Please follow the instructions in RELEASING to push stuff out and" + @echo "send out the announcement mails.

For instructions about how to use the git service on +freedesktop.org, see: + + http://www.freedesktop.org/wiki/Infrastructure/git/Developers + +The Pixman master repository can be found at: + + git://anongit.freedesktop.org/git/pixman + +and browsed on the web here: + + http://cgit.freedesktop.org/pixman/ + + +Sending patches +--------------- + +The general workflow for sending patches is to first make sure that +git can send mail on your system. Then, + + - create a branch off of master in your local git repository + + - make your changes as one or more commits + + - use the + + git send-email + + command to send the patch series to pixman@lists.freedesktop.org. + +In order for your patches to be accepted, please consider the +following guidelines: + + - This link: + + http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#patch-series + + describes how what a good patch series is, and to create one with + git. + + - At each point in the series, pixman should compile and the test + suite should pass. + + The exception here is if you are changing the test suite to + demonstrate a bug. In this case, make one commit that makes the + test suite fail due to the bug, and then another commit that fixes + the bug. + + You can run the test suite with + + make check + + It will take around two minutes to run on a modern PC. + + - Follow the coding style described in the CODING_STYLE file + + - For bug fixes, include an update to the test suite to make sure + the bug doesn't reappear. + + - For new features, add tests of the feature to the test + suite. Also, add a program demonstrating the new feature to the + demos/ directory. + + - Write descriptive commit messages. Useful information to include: + - Benchmark results, before and after + - Description of the bug that was fixed + - Detailed rationale for any new API + - Alternative approaches that were rejected (and why they + don't work) + - If review comments were incorporated, a brief version + history describing what those changes were. + + - For big patch series, send an introductory email with an overall + description of the patch series, including benchmarks and + motivation. Each commit message should still be descriptive and + include enough information to understand why this particular commit + was necessary. + +Pixman has high standards for code quality and so almost everybody +should expect to have the first versions of their patches rejected. + +If you think that the reviewers are wrong about something, or that the +guidelines above are wrong, feel free to discuss the issue on the +list. The purpose of the guidelines and code review is to ensure high +code quality; it is not an exercise in compliance. diff --git a/src/pixman/RELEASING b/src/pixman/RELEASING new file mode 100644 index 0000000..657857d --- /dev/null +++ b/src/pixman/RELEASING @@ -0,0 +1,59 @@ +Here are the steps to follow to create a new pixman release: + +1) Ensure that there are no uncommitted changes or unpushed commits, + and that you are up to date with the latest commits in the central + repository.

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).

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.

This is a macro for implementing cache preload.

Prefetch distance is + * handled in an 'incremental' way: it starts from 0 and advances to the + * optimal distance over time. After reaching optimal prefetch distance, + * it is kept constant. There are some checks which prevent prefetching + * unneeded pixel lines below the image (but it still can prefetch a bit + * more data on the right side of the image - not a big issue and may + * be actually helpful when rendering text glyphs). Additional trick is + * the use of LDR instruction for prefetch instead of PLD when moving to + * the next line, the point is that we have a high chance of getting TLB + * miss in this case, and PLD would be useless. + * + * This sounds like it may introduce a noticeable overhead (when working with + * fully cached data). But in reality, due to having a separate pipeline and + * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can + * execute simultaneously with NEON and be completely shadowed by it. Thus + * we get no performance overhead at all (*). This looks like a very nice + * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher, + * but still can implement some rather advanced prefetch logic in software + * for almost zero cost! + * + * (*) The overhead of the prefetcher is visible when running some trivial + * pixels processing like simple copy.

When a pixel row is long enough, there + * are three distinct phases of prefetch: + * * an inner loop section, where each time a cacheline of data is + * processed, another cacheline is preloaded (the exact distance ahead is + * determined empirically using profiling results from lowlevel-blt-bench) + * * a leading section, where enough cachelines are preloaded to ensure no + * cachelines escape being preloaded when the inner loop starts + * * a trailing section, where a limited number (0 or more) of cachelines + * are preloaded to deal with data (if any) that hangs off the end of the + * last iteration of the inner loop, plus any trailing bytes that were not + * enough to make up one whole iteration of the inner loop + * + * There are (in general) three distinct code paths, selected between + * depending upon how long the pixel row is. If it is long enough that there + * is at least one iteration of the inner loop (as described above) then + * this is described as the "wide" case. If it is shorter than that, but + * there are still enough bytes output that there is at least one 16-byte- + * long, 16-byte-aligned write to the destination (the optimum type of + * write), then this is the "medium" case. If it is not even this long, then + * this is the "narrow" case, and there is no attempt to align writes to + * 16-byte boundaries.

A Region is simply a set of disjoint + * (non-overlapping) rectangles, plus an "extent" rectangle which is the + * smallest single rectangle that contains all the non-overlapping rectangles. + * + * A Region is implemented as a "y-x-banded" array of rectangles. This array + * imposes two degrees of order. First, all rectangles are sorted by top side + * y coordinate first (y1), and then by left side x coordinate (x1). + * + * Furthermore, the rectangles are grouped into "bands". Each rectangle in a + * band has the same top y coordinate (y1), and each has the same bottom y + * coordinate (y2). Thus all rectangles in a band differ only in their left + * and right side (x1 and x2). Bands are implicit in the array of rectangles: + * there is no separate list of band start pointers. + * + * The y-x band representation does not minimize rectangles. In particular, + * if a rectangle vertically crosses a band (the rectangle has scanlines in + * the y1 to y2 area spanned by the band), then the rectangle may be broken + * down into two or more smaller rectangles stacked one atop the other. + * + * ----------- ----------- + * | | | | band 0 + * | | -------- ----------- -------- + * | | | | in y-x banded | | | | band 1 + * | | | | form is | | | | + * ----------- | | ----------- -------- + * | | | | band 2 + * -------- -------- + * + * An added constraint on the rectangles is that they must cover as much + * horizontal area as possible: no two rectangles within a band are allowed + * to touch. + * + * Whenever possible, bands will be merged together to cover a greater vertical + * distance (and thus reduce the number of rectangles). Two bands can be merged + * only if the bottom of one touches the top of the other and they have + * rectangles in the same places (of the same width, of course). + * + * Adam de Boor wrote most of the original region code. Joel McCormack + * substantially modified or rewrote most of the core arithmetic routines, and + * added pixman_region_validate in order to support several speed improvements + * to pixman_region_validate_tree. Bob Scheifler changed the representation + * to be more compact when empty or a single rectangle, and did a bunch of + * gratuitous reformatting.
