Subject: [9fans] about KTZERO mismatch in mkfile and mem.h
Date: Tue, 21 Jan 2014 01:20:15 +0000 [thread overview]
Message-ID: <EC80728D-5B0F-45BD-A520-D99922F52F1B@fb.com> (raw)
Hi,
in 9/pc/mem.h it says:
/*
* Address spaces
*/
#define KZERO 0xF0000000 /* base of kernel address space */
#define KTZERO (KZERO+0x100000) /* first address in kernel text - 9load sits below */
and in 9/pc/mkfile:
# must match mem.h
APBOOTSTRAP=0xF0003000
KTZERO=0xF0100020
so why the difference? what is this additional 20 for KTZERO?
