Use net_device_operations structure and netdev_nullify() to allow for

2007-01-31 23:58:52 +00:00
c789e8640b
Added __umoddi3
2007-01-31 22:26:14 +00:00
7d9267561b
Don't call PXENV_STOP_UNDI in the kpxeprefix. This slighy breaks the
...
clean separation between loading and starting, but does mean that more
PXE stacks survive the process.
2007-01-29 15:21:10 +00:00
2cf1e33df1
Split bootsector execution code out into bootsector.c.
...
Added basic El Torito ISO image boot capability
2007-01-29 04:21:38 +00:00

Handle (64-bit) / (32-bit) = (64-bit), i.e. one step beyond that

Yet more synonyms that people tend to use.
2007-01-26 01:30:16 +00:00

Use base "0" in strtoul for consistency with "mem="
2007-01-24 22:54:08 +00:00
99cb46943f
"vga=" is specified in decimal, not hex.
2007-01-22 23:56:24 +00:00

Misread the definition of the type_of_loader field; it should include a
...
version.
2007-01-19 15:40:01 +00:00
73b09ecba6
Use stdio.h instead of vsprintf.h
2007-01-19 01:13:12 +00:00
5d57cd47a2
Declaring the CPU architecture in the middle of an assembly file is
...
somewhat redundant, and also causes gas to complain when we include
the profiling code (which uses an i586 instruction).
2007-01-18 18:53:32 +00:00
bd95927386
Accelerate memcpy() by around 32% on large, dword-aligned copies.
2007-01-18 15:18:02 +00:00
544fa25928
Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously
...
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
2007-01-16 08:36:42 +00:00
a5f6408d8e
We can now load an initrd as well as a kernel
2007-01-14 16:09:01 +00:00
b9f99858ab
Make the getmemsize() prototype available in memsizes.h, for code that
...
doesn't want to go to the hassle of processing a full memory map.
2007-01-14 15:32:25 +00:00
10c9b03cdb
Actually, the initrd image should be architecture-independent.
2007-01-14 15:07:11 +00:00
f92e04dea4
Add dummy "initrd" image format, just so that images can be marked as
...
initrds.
2007-01-14 15:03:39 +00:00
8a490146bf
Copy command line at execution time rather than load time.
...
Parse command line for "vga=" and "mem=" parameters
2007-01-14 14:29:30 +00:00
3ccd7335f0
Split bzimage_load into separate functions
2007-01-14 13:36:33 +00:00
97a3037f76
Can start a Linux kernel directly (albeit with no initrd support)
2007-01-14 12:34:35 +00:00
3cbf0db0a3
Remove some references to no-longer-existent source files.
...
Add a path for isolinux.bin that is correct on my system; hopefully it
will work on others too.
2007-01-14 11:52:22 +00:00

.lilo and derived targets (e.g. .iso) now load properly.

Can almost start a kernel now. It dies with "No setup signature found"
2007-01-14 06:36:20 +00:00
b07161f397
Placeholder bzImage support
2007-01-14 04:27:25 +00:00

Replace image->entry with image->priv.
2007-01-14 04:04:28 +00:00

Mostly updated. Won't work yet.
2007-01-14 03:49:07 +00:00

Obsolete for some time
2007-01-14 02:24:41 +00:00

Move pxe_boot() code to pxe_image.c
2007-01-14 02:20:10 +00:00

Use debug autocolourisation.
...
Shut down before jumping to the multiboot image.
2007-01-14 00:57:43 +00:00
dca369ddc3
Call hide_etherboot() from startup(), rather than requiring the prefix to
...
do it.
2007-01-14 00:53:56 +00:00
ece4ff929e
Use _text, rather than assuming _text==0.
2007-01-14 00:03:07 +00:00
f547f148d3
Use {get,set}_fbms() so that allocated base memory is correctly hidden.
2007-01-14 00:01:16 +00:00
0b0e34e667
Provide {get,set}_fbms() in basemem.h.
...
set_fbms() will also update the E820 hidden region.
2007-01-13 23:57:31 +00:00
aaed3d50a8
Some operating systems get a nasty shock if a region of the E820 map seems
...
to start on a non-page boundary. Make life safer by rounding out our
edited regions.
2007-01-13 23:38:33 +00:00
d0f4e9a54b
Add some trace messages for important events
2007-01-13 17:54:41 +00:00
f11900a9c6
I prefer IMAGE_XXX to XXX_IMAGE.
...
Add IMAGE_PXE to use the new image format framework. "kernel pxelinux.0"
now works.
2007-01-13 17:28:51 +00:00
bd863e4112
Add header for pxe_boot()
2007-01-13 17:23:44 +00:00

Pick up the return status code from the correct place now that we

don't overwrite the parameter block until *after* the debug code.
2007-01-13 16:55:57 +00:00

When an UNDI API call fails, print everything there is to know about it.
2007-01-13 16:53:55 +00:00
6a3c76c8e0
Always send EOI. We can't feasibly share interrupts (since we have no
...
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts. Joy.
2007-01-13 14:45:26 +00:00
86171c53f4
Damn Broadcom and their damned incorrect assumptions about x86 memory
...
allocation.
2007-01-13 01:48:12 +00:00
bcd6ca3291
Place multiboot tables in base memory; at least some OSes won't see it
...
if we don't.
2007-01-12 16:25:05 +00:00
0f29e0e46e
Ensure multiboot modules are in ascending order of memory start
...
address, to work around OS bugs.
2007-01-12 12:03:19 +00:00
53e948bba8
Fix the memory map.
2007-01-12 11:38:04 +00:00

Force probing of multiboot before ELF.
2007-01-12 08:10:35 +00:00

Place command-line inline, to save on memory allocation hassles.
2007-01-12 05:26:19 +00:00
77b7640af4
Fix the only bug (which was to use DBGC() in place of DBG()!) and add 4kB
...
alignment.
2007-01-12 03:28:03 +00:00
45ec9c907e
First version of an external memory allocator (not tested)
2007-01-12 03:15:29 +00:00
1d313234b3
Rename copy_user() to memcpy_user(). Add memmove_user() and

userptr_add().
2007-01-12 03:14:15 +00:00
859da6bd32
Allow external code to update hidden memory regions.

e4c6418ac0
We may be required to page-align modules, so let's make sure we catch
...
it if we don't.
2007-01-12 00:09:16 +00:00
f59ad50504
Provide registration mechanism for loaded images, so that we can e.g.
...
refer to them by name from the command line, or build them into a
multiboot module list.
Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
2007-01-11 23:43:29 +00:00
f31d91bce5
Populate multiboot information structure before calling OS.
2007-01-11 21:21:02 +00:00

Whoever put together the grub multiboot.h header is insane.
2007-01-11 21:20:27 +00:00
200d92c76d
Avoid namespace clashes
2007-01-11 19:42:26 +00:00
bcc98c78b8
Added fields present in the documentation but not in the header file.
2007-01-11 19:41:13 +00:00
dc51af59a4
Capable of starting a multiboot kernel (albeit without the multiboot
...
information table yet).
2007-01-11 18:41:15 +00:00
9196e9069c
Add PHYS_CODE, for use as in __asm__ ( PHYS_CODE ( ... ) ), comparable
...
to the REAL_CODE interface.
2007-01-11 18:40:46 +00:00
d488a172eb
Capable of loading a multiboot image into memory
2007-01-11 17:44:42 +00:00

Downloaded from current grub CVS.
2007-01-11 16:22:03 +00:00

Move include/image.h to include/gpxe/image.h
2007-01-11 16:04:36 +00:00
7ad1c2eaa8
Removed the Etherboot-specific ELF-image code and replaced it with a
...
generic ELF loader, to be used by the multiboot code.
2007-01-11 14:44:03 +00:00
3634e705b7
Remove osloader.c and replace with a prep_segment() that uses userptr_t
...
and get_memmap() in image/segment.c
2007-01-11 14:32:26 +00:00
ceca6b185c
Added user_to_phys() and memset_user().
2007-01-11 14:27:27 +00:00
c980cdd0aa
Move memmap.h out of arch/i386; it no longer contains anything
...
architecture-dependent and is needed by the ELF code.
2007-01-11 14:08:44 +00:00
c6a4055fae
Add phys_to_user() and copy_user().
2007-01-11 14:01:20 +00:00
e2dcd05b67
Update buffer-handling code to enable expandable buffers.
2007-01-11 03:50:47 +00:00
fdc97499bf
Add device description fields to struct device.
2007-01-10 15:27:48 +00:00
489a4004d7
Give UNDI device a more meaningful name.
2007-01-10 05:52:04 +00:00
dad5274522
Add "name" field to struct device to allow human-readable hardware device
...
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).
2007-01-10 04:22:09 +00:00
c65fae2475
Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.
2007-01-09 21:47:01 +00:00
18e5353bed
Rename pkb_available() to pkb_tailroom() for consistency with Linux's
...
skb_tailroom(). Add pkb_headroom().
