b90d321dfb Change %dl fixup rules for INT13: 
INT 13,08 : read number of drives from 40:75
INT 13,15 : do nothing
all others : restore original value of %dl

c7d9fdb5b9 Proof of concept; works, but has several hard-coded hacks. 2007-07-09 20:28:40 +01:00

8bce52d348 Set CF by default, clear on success (rather than clearing and setting 
on failure).

4ff85d9f15 Add -mpreferred-stack-boundary=2 to i386 CFLAGS as it's almost always a win. 2007-07-09 03:32:54 +01:00
Michael Brown
4c418d2100 Use net_device_operations structure and netdev_nullify() to allow for 
safe dropping of the netdev ref by the driver while other refs still
exist.

Add netdev_irq() method.  Net device open()/close() methods should no
longer enable or disable IRQs.

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.

fbda4837b0 Allocate heap at first usage, rather than assuming we can fit it in 
below _text.  This should help with the gPXE-on-gPXE-via-PXE case.

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).

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.

 2007-06-28 21:50:36 +01:00
Michael Brown
03ca71c38d Move stack to below 0x7c00; leaving it at the default location 
(0x7ef4) tends to really screw up anything that loads at 0x7c00...

f77815f2b1 Kill off hotplug.h and just make net devices normal reference-counted 
structures.

DHCP still broken and #if 0'd out.
 2007-06-27 14:48:31 +01:00
Michael Brown
1ae549b892 Add our own trivial version of stdarg.h. This makes our build 
entirely self-hosted (which avoids problems when building the same
tree on multiple systems - e.g. when you have /home NFS-mounted).

Also saves around 50 bytes in total - not sure why.

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

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.

5d57cd47a2 Declaring the CPU architecture in the middle of an assembly file is 
somewhat redundant, and also causes gas to complain when we include

Michael Brown
544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously

things reached through a userptr_t).

b9f99858ab Make the getmemsize() prototype available in memsizes.h, for code that

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.
