2cfe0dee1f Don't trash the %ecx value returned by relocate(). This was causing 
us to round down the size for the relocation copy to the nearest 64kB
(+0x10 bytes); this just happened to work on most machines because the
last 64kB of the image is all-zeroes anyway (it's the .bss).

c94cdf2b7d Move .zinfo to libprefix.S; it doesn't belong with the decompression code. 2007-07-17 12:52:54 +01:00

84551d485e Update all prefixes currently referring to _load_size to include a 
compressor fixup section.

0929142a15 Rename _rom_size to _load_size_sect, since hdprefix.S also uses it. 2007-07-16 17:03:19 +01:00

ab859a5355 Use a single _payload_offset linker-defined variable to locate the 
start of the non-prefix blocks in the loaded image, and rely on the
image ordering.  This should make introducing compression much easier.

03ca71c38d Move stack to below 0x7c00; leaving it at the default location 
(0x7ef4) tends to really screw up anything that loads at 0x7c00...

520d9c36af Updated ISAPnP, EISA, MCA and ISA buses to current device model. 
ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.

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.

b04b0ddc31 .lilo and derived targets (e.g. .iso) now load properly. 2007-01-14 11:50:44 +00:00

dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.

addresses if the signature checks fail.

697bcc9d24 Since we now always unload the base code stack (even if we keep UNDI), 
we can never return to the PXE stack and must always use INT 18.

47222d5ed8 Call PXENV_UNDI_GET_NIC_TYPE to identify NIC physical device. 
Record all information required for populating a struct undi_device.

Make debugging output more human-readable.

fbdebac5f4 Copy pxelinux's shutdown sequence: use UNLOAD_STACK without STOP_BASE, 
and call UNDI_SHUTDOWN first to make sure the NIC is in a safe state.

8f8af10b22 New strategy: always stop both base code and UNDI. Always free base code 
memory (unless we get an error while stopping the base code).  Leave UNDI
resident (though stopped) for .kpxe.

Still need to add code to record the device identification parameters
prior to stopping UNDI.

de2fc50f4c Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than 
having to edit PXELOADER_KEEP_ALL as a config option.

6abfaa153b Towards making KEEP_IT_REAL work again. 
Fix bug that caused over-allocation of .text16 and .data16 memory areas
by a factor of 16.

ef37f78cbe Cut out almost all the optional code paths, drastically simplifying the 
flow of control through this code.

We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.

UNDI loader is still missing.

89da833c5d init_librm() and prot_call() are now real-mode far calls. 
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().

15ee09ed10 Restructured PCI subsystem to fit the new device model. 
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

832807726a Add infrastructure to support access to .data16 (and .text16) variables 
from protected-mode code.

Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.

Move most real-mode librm variables from .text16 to .data16.

f8f75cef5b BSS is now zeroed by libprefix (along with the otherwise non-zeroable 
portions such as the stack) during the installation process.

init_fns() are called from main().  We need to think about initial
control flow some more.

10c28a51bd Create two easy-to-use entry points in libprefix: install and 
install_prealloc.  I *think* these will suffice for all the 16-bit
prefixes.

9fcded3d23 Towards a(nother) new real-mode infrastructure, in which we take 
advantage of the fact that we have to have a permanently-resident block
in base memory.
