c00209396c Fixed loss of setting of the RB_BOOTINFO flag in rev.1.43. Fixed wrong
comment about this flag in rev.1.61.  It is not historical like the
comment said; it is the flag that says that most of what is laboriously
put in the bootinfo struct is actually there.  Newer kernels were
bootable by even the broken boot2 without losing anything except the
symbol table, but older kernels need at least the memory sizes.

Restoring the "|" with RB_BOOTINFO that was lost in rev.1.43 costs 5
bytes.  The fix can be done in only 4 bytes by fixing some code that
was removed in rev.1.61 (put RB_BOOTINFO back in in the initial value
of "opts" and fix RBX_MASK to not clobber it.)

8c0a2b3383 Many newer CF do not handle having the entire track read from them at
boot time.  Instead, read it a sector at a time.  While this sounds
like a significant slowdown, I've not been able to measure any
signficant difference.

40205a0623 Revision 1.13, besides its useful part, replaced bsd.prog.mk by
bsd.lib.mk and thus broke the build since AFLAGS were not taken
into considered anymore, as bsd.lib.mk currently has wrong .s.o
rule that uses cc(1) instead of as(1).

Revision 1.14 reverted to using as(1), and revision 1.15 brought
AFLAGS back to the business, but revision 1.14 also broke "make
clean".

To fix this, but not break anything that was fixed in revisions
1.13-1.15, we revert mostly to revision 1.13 except for switching
back to using bsd.prog.mk.  This gives us back the default .s.o
rule from sys.mk that uses as(1), and fixes "make clean" by
restoring the full contents of OBJS.

Also fixed LDFLAGS.

c83b0b621f When looking for the ':' separator in the root path, don't go past
the terminating '\0'. Since the initialisation of rootpath in
libstand/bootp.c may copy junk into the rest of the buffer, it was
possible for the code to find a ':' after the '\0' and do the wrong
thing.

48a0b96a50 Enable the i386 loader to load and run an amd64 kernel. If this puts
things over floppy size limits, I can exclude it for release builds or
something like that.  Most of the changes are to get the load_elf.c file
into a seperate elf32_ or elf64_ namespace so that you can have two
ELF loaders present at once.  Note that for 64 bit kernels, it actually
starts up the kernel already in 64 bit mode with paging enabled.  This
is really easy because we have a known minimum feature set.

Of note is that for amd64, we have to pass in the bios int 15 0xe821
memory map because once in long mode, you absolutely cannot make VM86
calls.  amd64 does not use 'struct bootinfo' at all.  It is a pure loader
metadata startup, just like sparc64 and powerpc.  Much of the
infrastructure to support this was adapted from sparc64.

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.

401e7fff61 Revert previous untested revision. The i386 loader consists of three parts:
At the front is btxldr, in the middle is BTX itself (our mini-kernel), and
then the 'client' (loader.bin) which is the actual loader itself.  boot2
just executes a raw ELF or a.out binary with the only setup provided being
that a bootinfo structure is passed on the stack.  Now, since loader.bin
is a BTX client, the loader needs to be able to locate a BTX kernel for
the client to execute in the context.  Thus, just like pxelder, btxldr
uses the a.out header on the loader binary to find the BTX kernel stored
in the loader and set it up.  It does _not_ just reuse the BTX kernel
that boot2 invoked it with.  This is because it can't assume that it will
_have_ a "spare" BTX kernel lying around.  For example, when cdboot
loads the loader there isn't an existing BTX kernel.  In fact, cdboot
will only work with an a.out loader as well since it also "borrows" the
BTX kernel in the loader binary (which it finds by parsing the a.out
header) just as pxeldr does.  The only difference between cdboot and
pxeldr is where they get /boot/loader from.

If we wanted to make /boot/loader be an actual ELF binary we would need
to change the following utilites to handle that (and they all have to be
able to handle locating the BTX kernel inside of an ELF binary somehow):
- btxldr
- pxeldr
- cdboot

If we didn't want to require a flag day but make the transition smooth
then we need to be able to support both a.out and ELF versions of
/boot/loader which isn't exactly trivial since all three of these utilities
are written in assembly.

1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

e754a32842 Saved 176 bytes by compiling with -fno-guess-branch-probability. The
default of -fguess-branch-probablility causes time optimizations (?)
like rewriting `if (foo) x++;' as
`if (!foo) goto forth; back: ; ...; forth: x++; goto back;".  This is
pessimizes space especially well on i386's because one short branch
gets converted to 2 long ones.

Removed -fno-align-foo since it is implied by -Os.  Previous commit
messages seem to have overstated the new alignment bugs in gcc.  The
only case that affects boot2 is that -fno-align-functions (or
equivalently -falign-functions=1) actually gives -falign-functions=2.
This is caused by FUNCTION_BOUNDARY being 2 (bytes) instead of 1.
The default case where the optimization level is 1 and no alignment
options are given is more broken.  All alignments are minimal, modulo
the bug in FUNCTION_BOUNDARY.  This is caused by toplev.c setting
defaults too early.

Some hacks in previous commits ar not needed now, but may as well be
kept until gcc is fixed.  The previous on in the Makefile saved 96
bytes of text due to the wrong FUNCTION_BOUNDARY and 32 bytes of data
due to unrelated bloat in the alignment of large objects.  There aren't
even any options to control alignment of data.

- Axe -fforce-addr.  This gets us 32 bytes so we are down to only being

We still can't compile this with gcc 3.1.  The problem seems to be that
the -fno-align-foo options don't actually work.  Comparing the new and
old output it turns out that gcc is 4-byte padding all the functions and

unfortunate bloat to boot2.

fb74e5f595 Add splitfs vfs layer into libstand, which allows loading big kernels and
modules split across several physical medias. Following is how it works:

The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.

	foo.aa "Kernel floppy 1"
	foo.ab "Kernel floppy 2"
	foo.ac "Kernel and modules floppy"

For each file segment, the process is:

- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located

870fb18bc1 Oops, the previous revision (1.35) broke booting from floppies
because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.

Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).

5af9115c77 This is a new CD bootstrap utility designed to replace cdldr. According
to the El Torito standard for CD booting, a CD may boot in "No emulation"
mode without using a floppy image.  In this mode, the BIOS loads a program
off of the CD into memory and creates a BIOS device using 2048 byte sectors
for the CD.  According to the standard, this program can be up to 0xFFFF
virtual (512-byte) sectors long.  The old cdldr depended on this by having
the BIOS load the entire loader and the small cdldr stub as one binary
similar to pxeboot so that cdldr didn't have to read the CD to find the
loader.  However, the NT no emulation loader just uses 1 disk sector
(4 virtual sectors), so it seems that at least some BIOS writers just did
enough to get NT to boot by only loading 1 sector and ignoring the sector
count.  Thus, while cdldr should have worked in theory, it doesn't in
practice.  This replacment fits entirely in 1 sector and includes simple
ISO 9660 support.  It looks for /boot/loader on the CD and loads it up
using the BIOS.  This allows us to not have to depend on the limited size
of floppy images but use a full GENERIC kernel for CD-ROM installs in the
future, among other things.

This version of cdboot is a bit bloated as it includes some useful
debugging routines that people can pull to use in other x86 assembly
modules.  Even with all the debugging cruft, we still have 272 bytes to
spare.

in the BIOS overwriting part of boot1: specifically the function used to

b833d157c7 Always disable paging when exiting back to real mode after receiving a
fatal trap.  Also, reload the GDT register to point to BTX's GDT before
playing around with the segment registers to return to real mode.  This is
helpful if the kernel causes a fatal exception before it has setup its own
IDT and fault handlers.  For example, if one happens to break mtx_init().
Without these changes BTX would recursively page fault (if paging was not
disabled) or triple fault and reset the CPU (without the GDT reload)
instead of providing a potentially useful register dump.

Taking over the sector following the MBR causes problems on some

Since we need a number of further features (eg. handling extended

design anyway, rather choose to implement the additional stuff
separately and concentrate on compatibility rather than features
here.

ab9e9f9d2d Argh! Fix a brainfart of mine. In the old boot0, we relocated ourself
to 0x600 via a 'rep movsw'.  Once that was done, %cx was zero, so we could
simply use 'movb' to update the lower byte of %cx in preparation for
zeroing out the fake partition entry used to boot to other drives via F5.
Well, in the new boot0, we don't actually relocate ourselves, instead it
is easier to create the fake partition entry first and then just use it to
get the BIOS to load all of boot0 into memory at 0x600.  However, since we
aren't doing the relocate code anymore, we don't know that %cx == 0 when
we hit the 'movb' to setup %cx for clearning the fake partition entry.
Thus, if %ch != 0 when the BIOS started boot0, then it would end up zeroing
a lot more memory than just 8 words.  The solution is to do a word move of
$8 into %cx.

1dce5cb37f The new and improved boot0, v1.1. This version adds the following:
- Autodetection and support of the BIOS EDD extensions to work around the
  1024 cylinder limit on all but really ancient BIOS's.
- To work around some BIOS's which break when EDD is used with older drives,
  we only attempt to use EDD if the cylinder is > 1023.
- Since this new code required more space than we had left, expand boot0 to
  2 sectors (1024 bytes) in length.
- Add support for boot0 being multiple sectors using predefined constants.
  If boot0 needs to be extended in the future, all that is required is
  bumping the NUM_SECTORS constant.
- Now that we have more room to work with, add a few more fs type
  descriptions while making others more verbose.

bce816b9cc - Don't blindly assume that there are 8 hard drives installed. Instead,
use the BIOS Equipment List to determine how many hard drives are

- Don't bother to disable interrupts when setting up the stack.  The 8086
  and beyond implicitly disable interrupts after an instruction that sets
  %ss (for example, a pop or a mov) so that you can safely set %ss and %sp
  in two consecutive instructions.  An exception to this is the lss
  instruction, which can set both registers simultaneously and thus doesn't
  need this hack.

to use fewer macros and more actual assembly statements, which eases
maintenance.  Unfortunately, due to as(1) brokenness, we still use m4
macros for all 16-bit addresses, and all short jumps (i.e., 8-bit
relative addresses in the jump instruction) must be wrapped in .code32
directives to avoid useless bloat by as(1).  This also fixes a few
problems that were preventing boot0 from compiling with the latest
and greatest version of as(1).

below).  This did not work previously because interrupts were
disabled when PXE calls were being made, and they must be enabled.
This should also allow us to be compliant with all newer PXE rom's
from Intel.

For PXE 0.99, this has been tested using the Intel N440BX motherboard
and I am confident it will work on the Intel L440GX motherboard.

Lots of help/information from: jhb, peter

I would like to thank Michael Johnston <michael.johnston@intel.com>,
Mike Henry <mike.henry@intel.com>, and all the other PXE developers
at Intel for their help, and information in helping solve this
problem.

36273c5d79 Don't disable interrupts when calling a vm86 mode interrupt or routine
from user mode.  Don't disable interrupts when returning from vm86 mode
to user mode either.  Now, we only disable interrupts before calling a
hardware interrupt handler, which is the only time we _should_ be
disabling interrupts.

Because of this, err, feature, any routine that one called in vm86 mode
had to re-enable interrupts by setting the interrupt flag or interrupts
would remain disabled even after the routine returned.  For example, I
have a simple debugging routine that uses a vm86 mode function to dump
any arbitrary memory word that I use to read the BIOS timer or any other
memory location.  This function does 1 load instruction from memory and
then returns.  Since it didn't re-enable interrupts, the first time I
called it to read the BIOS timer, it disabled interrupts.   This also
affected the PXE bootstrap as it needs interrupts enabled while it is
processing.  This patch fixes both of those situations so that those
functions do not worry about having to enable interrupts.  Hardware
interrupt handlers worked fine with the old code because they always
enable interrupts as part of their routine.

If you have any problems with the loader after this commit, please
let me know.  I'd like to MFC it in a week or two since PXE support
needs it.

48a0c4ea04 Mega i386 loader commit.
- Don't hard code 0x10000 as the entry point for the loader.  Instead add
  src/sys/boot/i386/Makefile.inc which defines a make variable with the
  entry point for the loader.  Move the loader's entry point up to
  0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
  instead use m4 to achieve this.  Also, add a BTXLDR_VERBOSE knob in the
  btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
  instead of having i386/loader/Makefile do that.  Also, add in some more
  variables to make the pxeldr Makefile almost identical and thus to ease
  maintainability.
- Teach cdldr about the a.out format.  Cdldr now parsers the a.out header
  of the loader binary and relocates it based on that.  The entry point of
  the loader no longer has to be hardcoded into cdldr.  Also, the boot
  info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
  (such as DOS FAT) that we currently support.  This is still buggy as
  it assumes that a floppy with a DOS boot sector actually has a MBR and
  parses it as such.  I'll be fixing this in the future.
- The biggie:  Add in support for booting off of PXE-enabled network
  adapters.  Currently, we use the TFTP API provided by the PXE BIOS.
  Eventually we will switch to using the low-level NIC driver thus
  allowing both TFTP and NFS to be used, but for now it's just TFTP.

536fcb08bf This patch to BTX fixes several small things:
1) Fix a bug in the int15 function 87 emulation where we only copied half
   of what the BIOS asked for.  This caused the Mylex RAID adapter to go
   haywire and start trashing memory when you tried to boot from it.
2) Don't use interrupt 19 to reboot.  Instead, set the reboot flag to a warm
   boot and jump to the BIOS's reboot handler.  int 19 doesn't clear memory
   or restore the interrupt vector table, and thus really isn't safe.  For
   example, when booting off of PXE, the PXE BIOS eats up a chunk of memory
   for its internal data and structures.  Since we rebooted via int 19,
   using the 'reboot' command in the loader resulted in that memory not
   being reclaimed by the BIOS.  Thus, after a few PXE boots, the system
   was out of lower memory.
3) Catch any int 19 calls made by a BTX client or a user pressing
   Ctrl-Alt-Delete and shutdown BTX and reboot the machine cleanly.  This
   fixes Ctrl-Alt-Delete in the loader and in boot2 instead of presenting
   the user with a BTX fault.

c8bb85f758 Add the new cdldr CD bootstrap loader. This patch includes the following:
- Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel
  arguments.
- Add the cdldr bootstrap program.  This program is tacked onto the
  beginning of the standard 3rd stage boot loader (/boot/loader) to form
  the CD boot loader (/boot/cdboot).  When a CD is booted, the cdboot file
  is copied into memory instead and executed.  The cdldr stub emulates the
  environment normally provided by boot2 and then starts the loader.  This
  booting method does not emulate a floppy drive, but boots directly off of
  the CD.  This should fix the problems some BIOS's have with emulating a
  2.88 MB floppy image.
- Add support to the loader to recognize that it has been booted by cdldr
  instead of boot2 and use a simpler method of extracting the BIOS boot
  device.

228ace6ebf aThis patch updates the BTX to emulate the BIOS function "Copy Extended
Memory" called as function 0x87 of interrupt 0x15.  Since the Mylex RAID
adapter's BIOS used this function to access memory (actually PCI bus
space) beyond 16 MB, this patch also allows BTX to address all 4 Gig of
possible address space on i386+.  Since the loader does not have room for
4 MB of page tables, this was done by turning off paging.

Paging was turned off via a compile time setting which defaults to off.
To enable paging, simply define the make variable PAGING.

rnordier might want to clean this up later.

378972ac6b Transition from using Perl to using awk for our text-manipulation

c03b24b2d8 Damn, I thought I had committed this already, but it seems not.
Move the relocated boot1 and arg transfer space from 0x600/0x800 to
0x700/0x900.  In theory this should make no difference, apart from the fact
that Buslogic controllers happen to use a few bytes at 0x600 for some sort
of scratch space for it's int 0x13 hook (!!!), causing the machine to crash
badly when the boot2 code makes it's callbacks into boot1 for disk IO.

af1f6e0673 Implement a simple LRU block cache. By default this is initialised to 16k,
and will bypass transfers for more than 8k.  Blocks are invalidated after
2 seconds, so removable media should not confuse the cache.

The 8k threshold is a compromise; all UFS transfers performed by
libstand are 8k or less, so large file reads thrash the cache.
However many filesystem metadata operations are also performed using
8k blocks, so using a lower threshold gives poor performance.

Those of you with an eye for cache algorithms are welcome to tell me
how badly this one sucks; you can start with the 'bcachestats' command
which will print the contents of the cache and access statistics.
