I had a MIPS machine (Loongson 3A) with page size 16KB( could be 4KB, but had to handle cache alias in OS), IMHO, define KSTACK_PAGE to 1 is enough, what is your opinion? 2012/7/23 Konstantin Belousov <[email protected]> > On Mon, Jul 23, 2012 at 02:54:30AM -0400, Richard Yao wrote: > > What is the default kernel thread stack size on FreeBSD?
