Hello! Sorry for my English. It is no my first language(Russian). I have embedded system with XILINX ZYNQ-7000 processor(ARM Cortex-A9 2 cores). This system also has framebuffer video device. Framebuffer with image contains in DDR memory and is transmitted in display by HDMI interface through special DMA(Framebuffer DMA in FPGA). I write simple fbdev driver for this device and it work fine. This system not has any GPU. I found out, that mesa can perform software rasterization for Open GL swrast. Can I build mesa swrast for my device and how can I do it? I try do this with use cross compilation file. This is a cross compilation file for meson, cross_file.txt: [binaries] c = 'arm-linux-gnueabihf-gcc' cpp = 'arm-linux-gnueabihf-g++' ar = 'arm-linux-gnueabihf-ar' strip = 'arm-linux-gnueabihf-strip' pkgconfig = 'pkg-config' [host_machine] system = 'linux' cpu_family = 'arm' cpu = 'armv7hl' endian = 'little' [properties] needs_exe_wrapper = true sys_root = '/home/oleg/work/z-turn-dvi/sysroot' [paths] prefix ='/usr' I build mesa with that options: meson build/ --cross-file cross_file.txt \ -Dplatforms=surfaceless \ -Dosmesa=gallium \ -Dgallium-drivers=swrast \ -Ddri-drivers=[] \ -Dvulkan-drivers=[] \ -Degl=true \ -Dgles1=true \ -Dgles2=true \ -Dglx=disabled ninja -C build/ build fail with errors: [84/882] Linking target src/mapi/es1api/libGLESv1_CM.so.1.1.0.

Should I do it? And how it will work with my fbdev? Thank you for answers. And sorry for my English. _______________________________________________ mesa-users mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-users
