Mali

Overview
Mali400 is a GPU from ARM. More information can be found on the ARM website.

Mali 400 on A1x
Allwinner officially supports the Mali GPU driver on the Android platform only. In this article we cover native linux usage, for android refer to publicly available sources https://github.com/allwinnerwk https://github.com/allwinner-ics and many others.

Binary libraries download links
Mali-400 uses proprietary libraries that must be provided by SoC manufacturer. This libraries are built with Mali DDK in various variants defining supported APIs. Example: if VARIANT is mali400-vg-gles20-linux-ump, library will be built with support for OpenGL ES 2 and OpenVG.

Libraries depend on driver version, for each Mali-400 kernel module drivers update you need appropriate libraries version and appropriate X11/DRI2 drivers version. If this conditions will not be met, you will end with unsupported IOCTL's and basically unstable system.

Open-source Mali driver
There is a project to develop a completely open-source Mali driver (work in progress): http://limadriver.org/

Manual installation and details
This section will describe how to install and use official Mali-400 drivers from ARM. If you feel that manual installation is hard for you, see automated one below. First, you need working distro with installed xorg and wip/linux-sunxi-3.0/next_mali kernel, in this tutorial, I'm using linaro-alip 12.08 with LXDE. Second, you need to install development stuff: root@linaro-alip:~# apt-get install autoconf automake make libtool xorg-dev xutils-dev libdrm-dev Pay close attention to last two, without them compilation will likely fail with various headers missing. Now download Mali-400 drivers and UMP from ARM's site, I'm using mali400 directory in my root home folder for this, then unpack archives. cd mali400 wget http://www.malideveloper.com/files/DX910-SW-99003-r3p0-04rel0.tgz wget http://www.malideveloper.com/files/DX910-SW-99006-r3p0-04rel0.tgz tar zxvf DX910-SW-99003-r3p0-04rel0.tgz tar zxvf DX910-SW-99006-r3p0-04rel0.tgz Now go to UMP directory cd DX910-SW-99006-r3p0-04rel0/driver/src/ump By default UMP is configured to be cross-compiled, so we need to disable this: replace CROSS_COMPILE ?= arm-none-linux-gnueabi- with CROSS_COMPILE ?= in Makefile using your favourite editor. Now, because we have hardfloat armv7-a toolchain, edit CFLAGS string like this: - CFLAGS += -I$(UMP_DIR)/include -I$(UMP_DIR)/include/ump -Wall -march=armv6 -mthumb-interwork -fno-strict-aliasing -Wno-strict-aliasing -Wno-long-long -O3 + CFLAGS += -I$(UMP_DIR)/include -I$(UMP_DIR)/include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 Now you will be able to make libUMP using standard make root@linaro-alip:~/mali400/DX910-SW-99006-r3p0-04rel0/driver/src/ump# make gcc -c -o arch_011_udd/ump_frontend.o arch_011_udd/ump_frontend.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -c -o arch_011_udd/ump_ref_drv.o arch_011_udd/ump_ref_drv.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -c -o arch_011_udd/ump_arch.o arch_011_udd/ump_arch.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -c -o os/linux/ump_uku.o os/linux/ump_uku.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -c -o os/linux/ump_osu_memory.o os/linux/ump_osu_memory.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -c -o os/linux/ump_osu_locks.o os/linux/ump_osu_locks.c -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 gcc -shared -o libUMP.so ./arch_011_udd/ump_frontend.o ./arch_011_udd/ump_ref_drv.o ./arch_011_udd/ump_arch.o ./os/linux/ump_uku.o ./os/linux/ump_osu_memory.o ./os/linux/ump_osu_locks.o -I./include -I./include/ump -Wall -march=armv7-a -mthumb-interwork -fno-strict-aliasing -fPIC -Wno-strict-aliasing -Wno-long-long -O3 ar rcs libUMP.a ./arch_011_udd/ump_frontend.o ./arch_011_udd/ump_ref_drv.o ./arch_011_udd/ump_arch.o ./os/linux/ump_uku.o ./os/linux/ump_osu_memory.o ./os/linux/ump_osu_locks.o after lib is compiled copy libUMP.so to your /lib or /usr/lib and copy DX910-SW-99006-r3p0-04rel0/driver/src/ump/include/ump/ contents to /usr/include/ump, without last one Mali-400 X11 drivers compilation will fail. Now go back to directory where you downloaded and unpacked DX910-SW-99003-r3p0-04rel0.tgz. Go to DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1 and run autoreconf -vi root@linaro-alip:~/mali400# cd DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1/ root@linaro-alip:~/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1# autoreconf -vi autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: running: libtoolize --install --copy libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, `.'. libtoolize: copying file `./config.guess' libtoolize: copying file `./config.sub' libtoolize: copying file `./install-sh' libtoolize: copying file `./ltmain.sh' libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force configure.ac:20: installing `./missing' src/Makefile.am: installing `./depcomp' autoreconf: Leaving directory `.' Now run ./configure script to produce makefiles, if you installed development stuff that I've mentioned in first step, you should have configure end without errors. Here is last lines of configure saying that everything is ok ./configure --prefix=/usr --x-includes=/usr/include --x-libraries=/usr/lib <..lots of output> checking whether to build shared libraries... yes checking whether to build static libraries... no checking if RANDR is defined... yes checking if RENDER is defined... yes checking if XV is defined... yes checking for XORG... yes checking whether xf86ConfigIsaEntity is declared... no configure: creating ./config.status config.status: creating Makefile config.status: creating src/Makefile config.status: creating config.h config.status: executing depfiles commands config.status: executing libtool commands Now you can compile driver using make. But wait, what is this? root@linaro-alip:~/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1# make make all-recursive make[1]: Entering directory `/root/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1' Making all in src make[2]: Entering directory `/root/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1/src' CC    mali_dri.lo  CC     mali_exa.lo mali_exa.c:35:54: fatal error: ../../../devicedrv/umplock/umplock_ioctl.h: No such file or directory compilation terminated. make[2]: *** [mali_exa.lo] Error 1 make[2]: Leaving directory `/root/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/mali400/DX910-SW-99003-r3p0-04rel0/x11/xf86-video-mali-0.0.1' make: *** [all] Error 2 This is multimillion corporation releasing bogus untested sources that you need to fix even if you bought their product, good job ARM.

Automated installation
Because stuff above seems to be too hard for people I've created git repo with fixed includes and simple build script that builds drivers, installs them and copies two files: xorg.conf and 10-mali400.rules to xorg.conf.d and udev rules.d accordingly. Install script will be updated soon to download needed libraries, for now you need to place them manually. Please report any bugs found.

Fails with "eglcreatewindow fail". Details coming soon.

Current state for r2p4
Use of libEGL produces random fails, see http://pastebin.com/GCVHSZJh for details. Most likely we have problems with our UMP integration or library is built wrong.
