images. (Oldest is kept.)

Various cd message updates.

ca80161f40 . Junk-filling gap+stack code on exec() if enabled (not enabled now) 
. Allow 'boot monitor' variable changes and additions by svrctl call

6e8f484b3b . added cd-probe logic; tries to find the right root filesystem 
if the boot monitor parameter is set. it also sets a boot monitor
  parameter (by talking to the PM) so userland knows it.
. ramdisk copy code made slightly smarter
. various select() prettifications (work in progress)

f0594a9e6d - Fixed comments in various system call handlers. Work in progress on new 
sys_privctl() call to dynamically start servers and drivers.

- Shutdown sequence slightly adjusted: called as watchdog timer to let the
  busy sys_abort() call from the PM return first.

- Changed umap_bios() to have more restrictive check: BIOS memory is now
  allowed in BIOS_MEM_BEGIN to END (interrupt vectors) and BASE_MEM_TOP
  to UPPER_MEM_END. Hopefully this keeps QEMU and Bochs happy.

8d3e390bda Added new BASE_MEM_TOP to restrict sys_vircopy() calls from BIOS. 
Updated comments at PRINTF_PROC --- it works again.

808202ee30 Removed printing functionality from IS server. 
This functionality is now provided by the LOG driver.

09830fc33e Allowed printing diagnostic messages (either from system processes or the 
kernel) to the log driver. The log driver forwards such output to the TTY.

Changed driver_task() not to send a reply if the return value is EDONTREPLY.

timers.h header file with explanation.

d2d975246d Kernel sends SIGKSTOP just before shutdown. Drivers do clean up and exit. 2005-07-20 15:28:05 +00:00

f1153541c7 Fixed bug in PM that caused update program not to be scheduled, so that 
sync was not periodically run. Chain of timers was accidentially broken.

Kernel sends SIGKSTOP signal on shutdown. FS calls sync to clean up.

c0718054e9 Various fixes and improvements. 
- fixed bug that caused IDLE to panic (irq hook inconsistency);
- kprintf() now accepts multiple arguments; moved to utility.c;
- prepare_shutdown() signals system processes with SIGKSTOP;
- phys_fill() renamed to phys_memset(), argument order changed;
- kmemset() removed in favor of phys_kmemset();
- kstrncpy() removed in favor of phys_copy();
- katoi, kstrncmp replaced by normal library procedure again;
- rm_irq_handler() interface changed (simply pass hook pointer);

0129d98ae1 Added new signal types for kernel events: 
- SIGKMESS: new kernel message (sent to TTY, IS, or LOG)
- SIGKSTOP: MINIX is shut down (sent to TTY-> switch to primary console)
- SIGKSIG: kernel signals pending (sent to PM)

Renamed SYS_SETPRIORITY to SYS_NICE.

198c976f7e System processes can be signaled; signals are transformed in SYS_EVENT message 
that passes signal map along. This mechanisms is also used for nonuser signals
like SIGKMESS, SIGKSTOP, SIGKSIG.

Revised comments of many system call handlers. Renamed setpriority to nice.

8c024e28a1 Changed Makefiles: drivers are now installed in /usr/sbin.

f2e16763e7 Removed PM signon for INET. Now daemonized in /usr/etc/rc. 
SIGTRAP generated in PM (where it belongs / no longer in kernel).
Updated Makefiles: servers are now installed in /usr/sbin.

eba45510a9 New alarm(2) timers mechanism. 
Kernel no longer keeps track of user alarms on behalf of the PM.
Instead, the PM maintains its own list of watchdog timers, and
uses one synchronous alarm (at the kernel) to get notifications
for expired user timers.
