56550e400e Redefine bzimage_exec_context::mem_limit to be the highest permissible 
byte, rather than the number of permissible bytes (i.e. subtract one
from the value under the previous definition to get the value under
the new definition).

This avoids integer overflow on 64-bit kernels, where
bzhdr.initrd_addr_max may be 0xffffffffffffffff; under the old
behaviour we set mem_limit equal to initrd_addr_max+1, which meant it
ended up as zero.  Kernel loads would fail with ENOBUFS.

688bac1656 Place multiboot command lines in base memory; Xen won't pick them up 
otherwise.  :(

d4947c05b2 Allow images to hold references to the originating URI. 
Some shuffling around of the image management code; this needs tidying up.

9fd6a0418f Allowed zero-cost enforced ordering of features in startup banner 
list.

Added FEATURE() macros to most relevant (non-driver) files.

6d2e4e719c Move uninitialised .data16 variables to .bss16; saves around 2000 
bytes of useless zeroes in the final image.

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).

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.

5578d3b2de Support 32-bit (linear) NBI images. We don't yet provide a bootp data 
block, so first32.c dies immediately.

2cf1e33df1 Split bootsector execution code out into bootsector.c.

ebb00e032c Misread the definition of the type_of_loader field; it should include a

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.

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.

8a490146bf Copy command line at execution time rather than load time.

f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.

bcd6ca3291 Place multiboot tables in base memory; at least some OSes won't see it 
if we don't.

0f29e0e46e Ensure multiboot modules are in ascending order of memory start 
address, to work around OS bugs.

e4c6418ac0 We may be required to page-align modules, so let's make sure we catch 
it if we don't.

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.
