[prefix] Prompt for entering gPXE shell during POST
...
The ROM prefix now prompts the user to enter the gPXE shell during POST;
this allows for configuring gPXE without needing to attempt to boot from
it. (It also slows down system boot by three seconds per gPXE ROM, but
hey.)
This is apparently a certain OEM's requirement for option ROMs.

Add ability for network devices to flag link up/down state to the

IPoIB reflects the Infiniband link state as the network device link state
(which is not strictly correct; we also need a succesful IPoIB IPv4
broadcast group join), but is probably more informative.

[HCI] Display "Not an executable image" when appropriate
...
PXE is a catch-all image format with no signature checks. If an
unsupported image file is loaded, it will be treated as a PXE image. In
most cases, the image will be too large to be loaded as a PXE image (which
has to fit in base memory), so the error returned to the user will be that
the segment could not fit within the memory region.
Add an explicit check to pxe_image.c to reject images larger than base
memory with ENOEXEC.
Add ENOEXEC to the error string table.

Always send EOI; do not chain to BIOS's default interrupt handler.

Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.

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
143e3b84a4
Downloaded from current grub CVS.
2007-01-11 16:22:03 +00:00
4fc9333159
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().
2007-01-09 20:56:31 +00:00
b7fcfe8ece
Added net device TX queue; this will be needed to support the PXE UNDI API
...
(which will need us to wait for TX completions).
Added debug autocolourisation to netdevice.c
2007-01-09 20:18:31 +00:00
3c2cc59d25
Added ability to break ISR processing over several calls to poll().
...
This will allow us to implement RX quotas.
2007-01-09 17:04:10 +00:00
aa7bda7b47
Send EOI after enabling interrupt, in case the device had asserted IRQ
...
to the PIC while it was disabled.
2007-01-09 14:53:19 +00:00
a2ffe8c123
Allow boot sector to completely destroy real-mode stack, but still
...
manage to return control.
2007-01-09 14:13:59 +00:00
a9369bb503
Leave protected-mode return address on PM stack when issuing a
...
real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack
contents, provided that it manages to return to real_call().
2007-01-09 14:13:06 +00:00
2738bdf74b
Obsoleted by drivers/net/undionly.c
2007-01-09 03:22:11 +00:00
d606edb41d
Added UNDI root bus driver (which saves including all the PCI bus code,
...
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).
This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).
