this is not a problem but more a question.
TK1 physical memory is 2G. and based on our current kernel setting the theoretical maximum VM we can use is 3G. SWAP is not an option as our application is time critical.
Issue we have:
Our user land application on TK1 is close to the VM limit 3G and once a while we will have application crash either caused by OOM killer or by run out of virtual memory space.
Checked the linux kernel 21.5, it did support custom split but only have below VM split.
- 1G kernel / 3G user space
- 2G kernel / 2G user space
- 3G kernel / 1G user space
I am wondering has anyone done a custom split like 512 kernel / 3512 userspace on TK1? I just want to make sure this is something doable before I start trying out.
Thanks in advance.
