Michael Brown 07e11f8af9 Minor debug improvement 2007-07-19 17:01:21 +01:00
Michael Brown 6d2e4e719c Move uninitialised .data16 variables to .bss16; saves around 2000
bytes of useless zeroes in the final image.
2007-07-16 13:22:12 +01:00
Michael Brown 89349d7fad Separated out initialisation functions from startup/shutdown functions. 2007-07-03 23:09:56 +01:00
Michael Brown 071356d976 Ensure that pxe_netdev is set before starting up PXE NBP. 2007-07-03 00:02:26 +01:00
Michael Brown e42eba4af4 Use a common base-memory packet buffer for DHCP construction (as used
by PXE and NBI) and UNDI packets (as used by undinet and UNDI).
2007-07-02 18:33:41 +01:00
Michael Brown 5f17089b14 pxe_netdev now holds a reference to the network device.
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.
2007-07-02 17:43:32 +01:00
Michael Brown e1646b4080 Place the actual version string in .data16, rather than just the
pointer to it.
2007-06-30 21:36:54 +01:00
Michael Brown 8130443f9f Separate out pxe_start_nbp() from pxe_image.c into pxe_call.c

2007-06-30 14:56:35 +01:00
Michael Brown d71b116f54 Fix stack on return from PXE NBP so that we can return properly. 2007-06-28 23:37:49 +01:00
Michael Brown 0d9b3e2dd2 Add 32-bit support.
Generate DHCP data block for images.
2007-03-22 16:18:46 +00:00
Michael Brown 160e66dbb9 Typo 2007-03-20 18:55:00 +00:00
Michael Brown 5578d3b2de Support 32-bit (linear) NBI images. We don't yet provide a bootp data
block, so first32.c dies immediately.
2007-03-14 00:39:12 +00:00
Michael Brown 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
Michael Brown 6a765fdc15 Use base "0" in strtoul for consistency with "mem=" 2007-01-24 22:54:08 +00:00
Michael Brown 99cb46943f "vga=" is specified in decimal, not hex. 2007-01-22 23:56:24 +00:00
Michael Brown ebb00e032c Misread the definition of the type_of_loader field; it should include a
version.
2007-01-19 15:40:01 +00:00
Michael Brown a5f6408d8e We can now load an initrd as well as a kernel 2007-01-14 16:09:01 +00:00
Michael Brown 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
Michael Brown 10c9b03cdb Actually, the initrd image should be architecture-independent. 2007-01-14 15:07:11 +00:00
Michael Brown f92e04dea4 Add dummy "initrd" image format, just so that images can be marked as
initrds.
2007-01-14 15:03:39 +00:00
Michael Brown 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
Michael Brown 3ccd7335f0 Split bzimage_load into separate functions 2007-01-14 13:36:33 +00:00
Michael Brown 97a3037f76 Can start a Linux kernel directly (albeit with no initrd support) 2007-01-14 12:34:35 +00:00
Michael Brown 784e10635a Can almost start a kernel now. It dies with "No setup signature found" 2007-01-14 06:36:20 +00:00
Michael Brown b07161f397 Placeholder bzImage support 2007-01-14 04:27:25 +00:00
Michael Brown 797edf28b7 Replace image->entry with image->priv. 2007-01-14 04:04:28 +00:00
Michael Brown 3bdbfe1f00 Mostly updated. Won't work yet. 2007-01-14 03:49:07 +00:00
Michael Brown 7bc03d37a2 Select a PXE network device before starting PXE NBP.
Move pxe_boot() code to pxe_image.c
2007-01-14 02:20:10 +00:00
Michael Brown 55e6d7b70c Use debug autocolourisation.
Shut down before jumping to the multiboot image.
2007-01-14 00:57:43 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown 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
Michael Brown 53e948bba8 Fix the memory map. 2007-01-12 11:38:04 +00:00

Michael Brown 9debfed07a Place command-line inline, to save on memory allocation hassles. 2007-01-12 05:26:19 +00:00
Michael Brown 1d313234b3 Rename copy_user() to memcpy_user(). Add memmove_user() and
userptr_add().
2007-01-12 03:14:15 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown f31d91bce5 Populate multiboot information structure before calling OS. 2007-01-11 21:21:02 +00:00

2007-01-11 14:32:26 +00:00
Michael Brown e28db95de6 Obsolete 2007-01-04 19:37:31 +00:00
Michael Brown 190276a8b6 NBI is due for removal 2006-05-24 13:53:35 +00:00
Michael Brown d8e99bf28f Gave up on adding POSIX errno's as required, and just added (almost) all
of them in one go.

EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.
2006-04-28 13:44:34 +00:00
Michael Brown 832e86246b gcc is rather over-aggressive about optimising out static data structures
even when __atribute__ (( unused )) is correctly set...
2006-04-24 18:31:37 +00:00
Michael Brown 809933d9f7 Split PXE code into preboot, udp, tftp, undi and loader units.
PXE code now compiles without errors (though it won't actually work).
