Drastically quieten down the verbose load progress messages. They were
more useful for debugging than anything, but are beyond a joke when loading
a few dozen modules.
Simplify the ELF extended symbol table load format. Just take the main
symbol table and the string table that corresponds. This is what we will
be getting local symbols from. (needed for the alpha stack tracebacks).
Use the (optional) full symbol tables in lookups. This means we have to
furhter distinguish between symbols that can come from the dynamic linking
table and the complete table.
The alpha boot code now needs to be adapted as ddb/db_elf.c cannot use
the simpler format.
I have not implemented loading the extended symbol tables from the syscall
interface yet, just for preloaded modules.
I am not sure about the symbol resolution. I *think* it's possible that
a local symbol can be found in preference to a global, depending on the
search sequence and dependency tree.
difference, but might later on when we implement some sort of multi-head
console mode. Select a console after probing them all.
Don't strdup a potentially NULL return from getenv().
If we don't select an active console, choose the first regardless.
Call the console init function, at startup time and on a manual change.
The env_setenv() function needs EV_VOLATILE because it's pointing to
data that isn't malloc'ed and will cause a fault if it's freed later.
Cosmetic change to the init-time character eater (like, make it increment
the index counter - if there's a problem, it would sit there in an infinite
loop instead of only running 10 times).
Also, make sure we set %dx each time around otherwise the commands
suddenly start trying to work on things like com92 instead of com1.
Make sure comc_init() is only run once.
Cosmetic change to init-time character eater.
should be MD code since one day we'll have to recover pages from deleted
preload data. MI code can't be expected to know how to deal with pmap
internals, assuming it gets done via pmap that is. :-)
- get dependency info from PT_DYNAMIC's DT_NEEDED tags.
- store MODINFOMD_DYNAMIC for the kernel's later use
setenv kernelname when we have it
Fix firstaddr/lastaddr calculation (duh! :-)
Explicitly skip string table with section names in it.
KLD modules are *not* PIC. (Shared libs are pic to avoid relocations
causing copy-on-write, that's irrelevant here).
setenv kernelname when we load it.
Use MODINFO_SSYM/ESYM for each symbol section when (if) there are
more than one being loaded.
Remove Mike's explicit data structures for dependency info. This is
done via DT_NEEDED etc in the dynamic section for now. This may need
to be revisited later on.
Do a much better job of DWIM with partial device specifications.
Fix the module metadata build process, which was completely broken.
Use a larger read buffer when copying large objects in; this
improves performance marginally and will avoid flushning any small caches
we might choose to implement.
Remove debugging in command_read().
Correctly strip leading controls on script commands.
Make 'ls' more DWIM in regard to pathnames. We can still do better.
- Don't whine about nodes we can't stat(); these are usually
symlinks that lead out of the filesystem.
- Autoboot is now controlled by $autoboot_delay, which is a value
in seconds or NO to disable autoboot.
- Don't autoboot at the end of boot.conf if we have already tried.
- Add a 'read' command to complement 'echo'. Both are still hidden.
- Improve the 'source' command/function so that it is possible to
source scripts off removable media. The entire script is read and
saved before beginning execution. Script lines beginning with
'@' will not be echoed when being executed. Script execution will
normally terminate at the first error, however if the script line
begins with '-' this behaviour is overriden for that command.
Strip any device name information from the kernel name
before passing it in.
biosdisk.c
Be more strict about matching device names to slice entries.
Only allow unsliced syntax on unsliced disks.
