. we cannot use the boot monitor to print the system diag buffer
. for serial, we do nothing, just reset, everything is already printed
. for not-serial, we print the current diag buffer using direct video
memory access from the kernel
Add guard pages to the top of the stack to catch overflow errors.
Moreover, fix a bug where libmthread would keep using a stack that was
just deallocated; a detached thread would deallocate its own stack after
it was finished running).
With -n -b file, a.out boot images can be used for CD booting;
with the new -n -B file option, plain binary (like bootxx_cd9660)
can be used instead.
Restore working the -h and -f options while there.
And add a new -F option for 2.8MB floppy image.
Register file timestamps
Remember the path tables in the primary descriptor
Put the size of the parent directory in the \1 entry, not own size
Allow the use of -b option without -a
Notes:
* Still missing the man page
* Filenames are still trimmed to 12 characters, because of
8.3 MS-DOS inherited compatibility (ISO9660 level 1);
also note that 7.4 or 9.2 filenames are accepted though
* Final . at end of filenames without extension is still missing
* VMS-compatible ;1 version suffix is still omitted
* Limit of 65,535 directories in path tables is not checked
Instead of using rootdev= or ramimagedev= in the boot monitor
which are changed to numbers and cannot be used with other
loaders, rootdevname= or ramimagename= are (MINIX-style)
device names always stored as strings.
Patch by Antoine Leca.
Kernels and system services are stored in a single directory in the
/boot/minix/ and rotated like /boot/images. /boot/minix_latest slink
is created automatically.
System serives are prefixed by "modNN_" to allow to easily load them
using "mod*" pattern.
Boot stuff dependencies from NetBSD.
Patch by Antoine Leca. Relocated to src/sys.
The port is using the same libminc.a as usual MINIX services (and does
not use NetBSD libkern); the headers imported from NetBSD sys/ tree
have been kept to a minimum (still numbers higher than 30 though.)
Note the peculiar way to use libraries (libsa, libi386, etc.): the
source code is shared, but each component builds its own copy of the
library, with its own set of preprocessor defines.
Also following functionality was added:
- Add install_master to the installboot from NetBSD.
- Check if enough space for bootxx.
Old installboot was renamed to installboot_minix.
- When cancelling ioctls, VFS did not remember which file descriptor
to cancel and sent bogus to the driver.
- Select state was not cleaned up when select()ing process was
interrupted.
- Process trying to do a system call at the exact same time as a user
trying to interrupt the process, could cause the system call worker
thread to overwrite state belonging to the worker thread trying to
exit the process. This led to hanging threads and eventual system hang
when this happens often enough.
