Return memory resersations in 3.4 debian image

[Nikita Krokosh]

Hello! I'm planning to try using kodi with my cubietruck.

Should I use desktop ubuntu image, or can I customize the legacy debian one?

 

One those things is returning memory reservations.

If I get it right I should edit uboot config and add:

 

sunxi_ve_mem_reserve=128M

cma=128+16M

 

Am I correct?

Are there any other changes I should change in default config to run kodi smoothly?

 

I'd go with debian if it's possible, but I can switch to ubuntu, if there's alot to change in 3.4 debian image.

CMA is not enable in armbian kernel. You have to compile it by yourself, to enable it. I am using the following settings, mentioned in other project, related to Kodi:

 

CONFIG_CMA=y
# CONFIG_CMA_DEBUG is not set
#
# Default contiguous memory area size:
#
CONFIG_CMA_SIZE_MBYTES=192
CONFIG_CMA_SIZE_SEL_MBYTES=y
# CONFIG_CMA_SIZE_SEL_PERCENTAGE is not set
# CONFIG_CMA_SIZE_SEL_MIN is not set
# CONFIG_CMA_SIZE_SEL_MAX is not set
CONFIG_CMA_ALIGNMENT=8
CONFIG_CMA_AREAS=7

You can change the size, but going above 192Mb is mentioned to cause instability. And going below is pointless, because memory is allocated dynamically. You can try desktop ubuntu image, but i had some troubles with it and there are no specific memory reservations there, i can't compile stable image from source either. I am not advice you to use old Debian Wheezy, because you can't install latest vdpau libraries because of incompatible old lic6 version.  You can try with no problems on new Debian 8 Jessie. About memory reservations, you have to edit the following file - /boot/boot.cmd . Mine look like this:

 

sunxi_ve_mem_reserve=128 sunxi_g2d_mem_reserve=32 sunxi_fb_mem_reserve=32

The last two doesn't seem to have any effect, but the first does. After you edit boot.cmd , create new boot.scr in the same directory:

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

and reboot. Let as know if you have some progress with Kodi .
