@Emric...I would have do that , but I am sorry I can't do anything against of company policy...
But u can do @ ur side... Write a simple program and do malloc and memset in while(1) , it will give u OOM (if u have enabled it or if u have applied OOM patch)... then you can checkout all the information printed by OOM..and I have tried more than 2-3 applications, but couldn't calculate the exact memory usage . Initially I got this problem when I was using browser, when I try to open the link , I got OOM...then I tried to calculate amount to free memory and used memory , I found that a large chunk of memory (200MB approx) was used by some other processes. then i tried with other small programs and get OOM for them, but thing is for every program there is always some memory confusion(who used extras memory).... yeah I do cat /proc/meminfo also....when I do malloc and memset , in meminfo I found that inactive pages has grown up, in meminfo I can mainupulate memory calculations easily and i got correct results... But in case of running browser on my target board I am needing to know where is rest of memory going when it is required by my browser.
