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.
Allocate space for, and copy, NDOSPART slice entries from the
MBR, not just one. Add some extra debugging while we're at it.
elf_freebsd.c
Initialise the symbol table start/end pointers in case we don't
have them.
Use bd_getdev() to work out a dev_t for the root device.
Allow $rootdev to override $currdev as the root device.
biosdisk.c
Save the slice table and disklabel when opening a disk.
Add bd_getdev(), which attempts to return a dev_t corresponding
to a given device. Cases which it still doesn't get right:
- The inevitable da-when-wd-also-exists
- Disks with no slice table (the slice number is not set correctly)
The first is difficult to get right, the second will be
fixed in an upcoming commit.
comconsole.c
vidconsole.c
getchar() should return an 8-bit value; some BIOSsen pack extra
information in %eax.
libi386.h
Remove some stale prototypes, add new ones.
Increase the robustness of the "is it time to boot yet" test;
if the time skipped the "when" time, we would miss it.
Don't spin in an endless loop if we don't find the first possible
kernel suggested. When we run out, don't try to load an empty
kernel name.
load_aout.c
printf format warnings
of the ..umm.. "wierd" way binutils lays out the file. The section
headers are nearly at the end of the file and this is a problem when
loading from a .gz file which can't seek backwards (or has a limited
reverse seek, ~2K from memory).
This is intended to be compatable with the ddb/db_elf.c code and the
alpha/libalpha/elf_freebsd.c layout. I've studied these (which are NetBSD
derived) but did it a bit differently. Naturally the process is similar
since it's supposed to end up with the same result.
bootblocks, the kernel shows up as the primary module:
[3:24am]~-100# kldstat
Id Refs Address Size Name
1 1 0xf0100000 ff00000 /kernel
^^^^ oops.. :-)
Based heavily on aout_freebsd.c. Hmm.. There's so much in common that
these could probably be combined and just check the metadata to see which
format it is.
