- [ABCD]_INDEX are not used anywhere
- value of *_SELECTOR is now calculated using the *_INDEX value so changing the
index does not break the selector
- TSS is now the last of the global selectors. There will be TSS per CPU on SMP
and the number will vary depending on the maximal supported number of CPUs
configured
- pproc_addr is not neccessary to get the address of a process if we know its
number
- local proc variables in system calls implementation (sys_task) conflicts with
the global proc array of all process, therefore the variable were renamed to
proc_nr as they hold the process number
- Modified the setup script to use the netconf script for the network
configuration:
- Moved step 2 to step 8 and renamed the steps in between.
- Autopart adapted to print step 3 instead of step 4.
- a better name for architecture specific init function
- some of x86 init code must execute in protected mode
- prot_init() removed from this function and still called in cstart() Imho this
should be called from the architecture specific assembly not cstart. cstart
perform Minix monitor specific tasks and will be touched once another
bootloader is in use, e.g. booting via tftp, therefore we keep it as is for
now.
- this is a backport from the SMP code which requires this. Merging will be simpler
If an exception happens in kernel while the kernel is booting and no processes
are running yet, saved_proc == NULL and priting any process related information
results in dumping rubish.
This check is mostly useful when debugging kernel stuff. Should _never_ happen
on a production kernel.
This is a backport form the SMP branch. Not required here, it only makes life
for SMP easier. And future merging too.
- filling the IDT is removed from prot_init()
- struct gate_table_s is a public type
- gate_table_pic is a global array as it is used by APIC code too
- idt_copy_vectors() is also global and used by idt_init() as well as
apic_idt_init()
- idt_init() is called right after prot_init() in system_init()
bin_img=1 in the boot monitor will make sure that during the boot procedure the
mfs binary that is part of the boot image is the only binary that is used to
mount partitions. This is useful when for some reason the mfs binary on disk
malfunctions, rendering Minix unable to boot. By setting bin_img=1, the binary
on disk is ignored and the binary in the boot image is used instead.
- 'service' now accepts an additional flag -r. -r implies -c. -r instructs RS
to first look in memory if the binary has already been copied to memory and
execute that version, instead of loading the binary from disk. For example,
the first time a MFS is being started it is copied (-c) to memory and
executed from there. The second time MFS is being started this way, RS will
look in memory for a previously copied MFS binary and reuse it if it exists.
- The mount and newroot commands now accept an additional flag -i, which
instructs them to set the MS_REUSE flag in the mount flags.
- The mount system call now supports the MS_REUSE flag and invokes 'service'
with the -r flag when MS_REUSE is set.
- /etc/rc and the rc script that's included in the boot image check for the
existence of the bin_img flag in the boot monitor, and invoke mount and
newroot with the -i flag accordingly.
