Added args to lock() and unlock() to tell them apart, for use when lock timing is enabled in minix/config.h. Added phys_zero() routine to klib386.s that zeroes a range of memory, and added corresponding system call. 2005-06-01 11:37:52 +02:00			`#ifndef DEBUG_H`

Reorganized system call library; uses separate file per call now. New configuration header file to include/ exclude functionality. Extracted privileged features from struct proc and create new struct priv. Renamed various system calls for readability. 2005-07-14 17:12:12 +02:00			`/* This header file defines all debugging constants and macros, and declares`

Better initialization of the memory map of processes that are part of the image. Removed NO_MAP flag. 2006-05-11 16:49:46 +02:00			`#include <ansi.h>`

- enable ipc warnings by default - ipc checking code in kernel didn't properly catch the sendrec() to self case; added special case check - triggered by PM using stock panic() - needs its own _exit() reported by Joren l'Ami. 2009-04-17 15:46:37 +02:00			`#define DEBUG_ENABLE_IPC_WARNINGS 1`
Make stack traces on exceptions possible. 2006-06-29 15:35:27 +02:00			`#define DEBUG_STACKTRACE 1`
Basic VM and other minor improvements. Not complete, probably not fully debugged or optimized. 2008-11-19 13:26:10 +01:00			`#define DEBUG_TIME_LOCKS 1`

more sanity checking. sanity checking disabled by default. give every process a full pagetable by default now. first step to disabling kernel page table code (processes might not have page tables -> no address translation). 2009-05-12 13:35:01 +02:00			`/* Runtime sanity checking. */`
Library call for cpu features; make kernel and vm use this to query cpu features (specifically: 4MB pages and TLB global bit). Only enable these features in CR4 if available. 4MB pages to be used in the near future. 2009-05-15 19:07:36 +02:00			`#define DEBUG_VMASSERT 1`
