Any one here tried setting up CMA on there RetroPie and how well did it work? I have the old 256M RPi and was considering trying CMA – Dynamic Memory Split so my pi can still be used for other things when not playing games.dk999Participant01/13/2015 at 17:42Post count: 11
Tried to use CMA on my Pi with Firmware 3.12.35+, though I only get a “lwl0: error creating SDL Window” and be greeted by the terminal instead of Emulationstation.
I’ve got the 512 B+ Model and the following cmdline.txt
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait coherent_pool=6M smsc95xx.turbo_mode=N
disable_overscan=0 overscan_scale=1 overscan_left=16 overscan_right=16 overscan_top=16 overscan_bottom=16 hdmi_group=1 hdmi_mode=16 arm_freq=1000 core_freq=500 sdram_freq=500 over_voltage=6 over_voltage_sdram=4 avoid_safe_mode=1 gpu_mem=256 gpu_mem_256=160 gpu_mem_512=416 cma_lwm=16 cma_hwm=32 force_turbo=0 overscan=1
It doesn’t work, no matter what I’m doing with the gpu_mem_512 line. It’s like emulationstation doesn’t like the cma-commands at all.
By the way, when using i.e. 384MB for the gpu as a fixed value ( no CMA ), I only get a blank white screen for emulationstation.
