Changing the memory split ?

[tnt]

Hi,

Is there any way to change the memory split to be more like 768/256 or 896/128 rather than 512/512 ?

I'm trying to build gnuradio and this involves multi-megabyte (like 14M !!!) C++ files that take like 700Mo of RAM to be compiled ... I'm doing that with swap on sdcard ATM but it's taking _forever_ ...

Cheers,

Sylvain

why don't you use cross compiling.

Where is the memory split documented? Is it referring to the split between user memory and video memory?

It seems somewhat wasteful if the board always dedicates 512MB to video memory - I imagine many people will be running their boards headless (i.e., without an attached monitor).

Did you try zswap or zram ? It provides some compression abilities to keep some swap or a ram disk in the RAM.

Anyway, shouldn't uBoot provide the ability to change the video memory allocation using the kernel parameters ?

Again, ATM using the provided SD image so can't easily build kernel modules.

Also, this has _nothing_ to do with video memory, I have no idea where cklin imagined that ... this is the dedicated epiphany memory.

And AFAICT it's not specified in the kernel command line, so I have no idea where/how it's configured.

The sources for the SD card will be published this week, along with a how to guide explaining how to build and configure the distro. A the memory split is completely configurable.
