Currently, the free list consists of a "small list" for sizes below 256, which are linearly spaced, and a "large list" which is manually split into a few chunks. This patch replaces it with a single log-linear policy, while expanding the range the large list covers. The old implementation had issues when a lot of large allocations happened. In this case, all the allocations went in the last catch-all bucket in the "large list", and what happens is: 1. The linked list grew in size over time, causing searching cost to skyrocket. 2. With the first-fit allocation policy, fragmentation was also making the problem worse. The new bucketing covers the entire range up until we start allocating large blocks, which will not enter the free list. It also makes the allocation policy closer to best-fit (although not exactly), reducing fragmentation. The increase in number of free lists does incur some cost when it needs to be skipped over, but the improvement in allocation performance outweighs it. For future work, these ideas (mostly from glibc) might or might not benefit performance: - Use an exact best-fit allocation policy. - Add a bitmap for freelist, allowing empty lists to be skipped with a single bit scan.

1. INTRODUCTION Wine is a program which allows running Microsoft Windows programs (including DOS, Windows 3.x, Win32, and Win64 executables) on Unix. It consists of a program loader which loads and executes a Microsoft Windows binary, and a library (called Winelib) that implements Windows API calls using their Unix, X11 or Mac equivalents. The library may also be used for porting Windows code into native Unix executables. Wine is free software, released under the GNU LGPL; see the file LICENSE for the details. 2. QUICK START From the top-level directory of the Wine source (which contains this file), run: ./configure make Then either install Wine: make install Or run Wine directly from the build directory: ./wine notepad Run programs as "wine program". For more information and problem resolution, read the rest of this file, the Wine man page, and especially the wealth of information found at https://www.winehq.org. 3. REQUIREMENTS To compile and run Wine, you must have one of the following: Linux version 2.0.36 or later FreeBSD 8.0 or later Solaris x86 9 or later NetBSD-current Mac OS X 10.8 or later As Wine requires kernel-level thread support to run, only the operating systems mentioned above are supported. Other operating systems which support kernel threads may be supported in the future. FreeBSD info: Wine will generally not work properly on versions before FreeBSD 8.0. See https://wiki.freebsd.org/Wine for more information. Solaris info: You will most likely need to build Wine with the GNU toolchain (gcc, gas, etc.). Warning : installing gas does *not* ensure that it will be used by gcc. Recompiling gcc after installing gas or symlinking cc, as and ld to the gnu tools is said to be necessary. NetBSD info: Make sure you have the USER_LDT, SYSVSHM, SYSVSEM, and SYSVMSG options turned on in your kernel. Mac OS X info: You need Xcode/Xcode Command Line Tools or Apple cctools. The minimum requirements for compiling Wine are clang 3.8 with the MacOSX10.10.sdk and mingw-w64 v8. The MacOSX10.14.sdk and later can only build wine64. Supported file systems: Wine should run on most file systems. A few compatibility problems have also been reported using files accessed through Samba. Also, NTFS does not provide all the file system features needed by some applications. Using a native Unix file system is recommended. Basic requirements: You need to have the X11 development include files installed (called xorg-dev in Debian and libX11-devel in Red Hat). Of course you also need "make" (most likely GNU make). You also need flex version 2.5.33 or later and bison. Optional support libraries: Configure will display notices when optional libraries are not found on your system. See https://wiki.winehq.org/Recommended_Packages for hints about the packages you should install. On 64-bit platforms, you have to make sure to install the 32-bit versions of these libraries. 4. COMPILATION To build Wine, do: ./configure make This will build the program "wine" and numerous support libraries/binaries. The program "wine" will load and run Windows executables. The library "libwine" ("Winelib") can be used to compile and link Windows source code under Unix. To see compile configuration options, do ./configure --help. For more information, see https://wiki.winehq.org/Building_Wine 5. SETUP Once Wine has been built correctly, you can do "make install"; this will install the wine executable and libraries, the Wine man page, and other needed files. Don't forget to uninstall any conflicting previous Wine installation first. Try either "dpkg -r wine" or "rpm -e wine" or "make uninstall" before installing. Once installed, you can run the "winecfg" configuration tool. See the Support area at https://www.winehq.org/ for configuration hints. 6. RUNNING PROGRAMS When invoking Wine, you may specify the entire path to the executable, or a filename only. For example: to run Notepad: wine notepad (using the search Path as specified in wine notepad.exe the registry to locate the file) wine c:\\windows\\notepad.exe (using DOS filename syntax) wine ~/.wine/drive_c/windows/notepad.exe (using Unix filename syntax) wine notepad.exe readme.txt (calling program with parameters) Wine is not perfect, so some programs may crash. If that happens you will get a crash log that you should attach to your report when filing a bug. 7. GETTING MORE INFORMATION WWW: A great deal of information about Wine is available from WineHQ at https://www.winehq.org/ : various Wine Guides, application database, bug tracking. This is probably the best starting point. FAQ: The Wine FAQ is located at https://www.winehq.org/FAQ Wiki: The Wine Wiki is located at https://wiki.winehq.org Gitlab: Wine development is hosted at https://gitlab.winehq.org Mailing lists: There are several mailing lists for Wine users and developers; see https://www.winehq.org/forums for more information. Bugs: Report bugs to Wine Bugzilla at https://bugs.winehq.org Please search the bugzilla database to check whether your problem is already known or fixed before posting a bug report. IRC: Online help is available at channel #WineHQ on irc.libera.chat. -- Alexandre Julliard julliard@winehq.org
