Subject: arm: why set MIN_GAP to 128M size
Date: Mon, 7 Nov 2016 14:09:23 +0800 [thread overview]
Message-ID: <58201A93.70309@huawei.com> (raw)
Hi everyone
arm:
/* gap between mmap and stack */
#define MIN_GAP (128*1024*1024UL)
The min_gap is 128M,
in the mmap_base function
unsigned long gap = rlimit(RLIMIT_STACK);
if (gap < MIN_GAP)
gap = MIN_GAP;
else if (gap > MAX_GAP)
gap = MAX_GAP;
I can not use the "128-stack_size"(M)
can i modify it to 64M?
Thanks,
jie chen
