db5a8bb2b8 Added dp8390 driver. Additional env_parse functions that take argc and argv. 2005-08-05 09:53:08 +00:00

c9ab8cce43 Changed minor number of /dev/zero from 6 to 5.
(Make sure to update your system accordingly or /dev/zero won't work.)
Cleaned up comments in MEMORY driver.

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet
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.

e561081545 Miscellaneous clean ups and fixes to the kernel.
Support for FLOPPY in boot image. (Set controller=fd at boot monitor.)
Moved major device numbers to <minix/dmap.h> (maybe rename to dev.h?)

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed.
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.

52965b6f17 Various updates to support dynamically starting drivers.
Output during initialization should be suppressed. Unless an error occurs.
Note that main() can now be main(int argc, char **argv) and arguments can
be passed when bringing up the driver.

d62e515660 Small update to SYS_IRQCTL -> setting an interrupt policy now allows the caller
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.

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.

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.

ec24a0798c Updated function key mapping because of possible changes to NOTIFY.
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.

c2cd510adf Removed debug dumps from the PM and FS servers. The dumps are now done by the
IS servers, which obtains a copy of the data through the getsysinfo() system
call. CTRL-F1 now is a special TTY key to shows function key mappings.

workaround hasn't been done.)

f2a85e58d9 Various updates.
* 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.

308d9a693c prettified rtl driver:
. no more kmalloc
 . no more umaps + physcopies / abscopies
 . the status register is directly readable from the drivers own
   address space now, and no physcopy is needed to read it
 . map+physcopy call combinations are replaced by vircopy calls

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical
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.

5a43b84e2d Fix for 'the kermit problem' (keyrepeats happening before the keyrepeat
timeout). A fix is to treat the alarm and interrupt cases differently and
only call the interrupt handler when an actual interrupt has been seen. No
apparent adverse effects.

0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts.
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

322ec9ef8b Moved stime, time, times POSIX calls from FS to PM. Removed child time
accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.

cd72f80639 Disabled clearing screen in tty driver, started console printing after an
initial 1-line scroll at last line. If clearing screen in trailer of boot
monitor is disabled, all previous boot monitor and console messages are
preserved on rebooting.

All that's needed now is a scrollback buffer to see all old messages..
(Even from the boot monitor, bios, previous boots...)

ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
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.
