New Shift-F6 dump for RS server at IS.
New getnpid, getnproc, getpproc library calls at PM.
New reincarnation server (basic functionality is there now).
. unmap device drivers from dmap when PM signals they are dead
. new null-io function (no_dev_io) to fill in for io functions
of unmapped drivers
. driver (process number) of unmapped drivers is NONE instead of
0 (a valid process number)
IS:
. print mutable flag of dmap table too
FS changes require sync() to be done 'manually' (currently by
reboot/shutdown) at shutdown time; could be caught by SIGTERM in
the future.
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.
Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.
This was caused by a change in the shared driver code. Not log's fault.
Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.
to provide an index (0 .. 31) that is passed in the HARD_INT message when an
interrupt occurs. The NOTIFY_ARG field contains a bitmap with all indexes for
which an interrupt occured.
and the new log driver if enabled.
new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.
* Removed some variants of the SYS_GETINFO calls from the kernel;
replaced them with new PM and utils libary functionality. Fixed
bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
Memory driver periodically checks this for /dev/random.
A better random algorithm can now be implemented in the driver.
Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
be done at the process manager with new 'other' library functions.
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.
