[prefix] Cope with image source addresses outside base memory
When PMM is used, the gPXE image source will no longer be in base memory.
Decompression of .text16 and .data16 can therefore no longer be done in
real mode.
Use BBS installation check to see if we need to hook INT19 even on a PnP
BIOS.
Verify that $PnP signature is paragraph-aligned; bochs/qemu BIOS provides
a dummy $PnP signature with no valid entry point, and deliberately
unaligns the signature to indicate that it is not properly valid.
Print message if INT19 is hooked.
Attempt to use PMM even if BBS check failed.
ROM initialisation vector now attempts to allocate a 2MB block using
PMM. If successful, it copies the ROM image to this block, then
shrinks the ROM image to allow for more option ROMs. If unsuccessful,
it leaves the ROM as-is.
ROM BEV now attempts to return to the BIOS, resorting to INT 18 only
if the BIOS stack has been corrupted.
[Makefile] Use bin/VVVVDDDD.rom instead of bin/pci_VVVV_DDDD.rom
The generate-by-PCI-device-ID rules (bin/pci_VVVV_DDDD.rom) are generally
used for building actual ROM images to be burned, and the burning
utilities generally run under some DOS variant. Change the filename from
pci_VVVV_DDDD.rom to VVVVDDDD.rom so that it is compatible with the DOS
8.3-character filename limit.
[PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API.
This allows pxelinux to execute arbitrary gPXE commands. This is
remarkably unsafe (not least because some of the commands will assume
full ownership of memory and do nasty things like edit the e820 map
underneath the calling pxelinux), but it does allow access to the
"sanboot" command.
RFC 4390 provides for the DHCP client identifier to contain the link-layer
hardware type and MAC address when the MAC address exceeds 16 bytes.
However, the hardware type field is only 8 bits; we were assuming 16 bits.
[Infiniband] Add preliminary support for multi-port devices.
Arbel and Hermon cards both have multiple ports. Add the
infrastructure required to register each port as a separate IB
device. Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.
Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and
owner-private data on Infiniband structures.
Pull out common code for handling management datagrams from arbel.c
and hermon.c into infiniband.c.
Add port number to struct ib_device.
Add open(), close() and mad() methods to struct ib_device_operations.
As written, if the if the UNDI ISR call clobbers the upper halves of
any of the GPRs (which by convention it is permitted to do, and by
paranoia should be expected to do) then nothing in the interrupt
handler will recover the state.
Additionally, save/restore %fs and %gs out of sheer paranoia - it's a
cheap enough operation, and may prevent problems due to poorly written
UNDI stacks.
Since we don't know what the UNDI code does, it is safest to
save/restore %eflags even though the lower half of %eflags is
automatically saved by the interrupt itself.

Allow port numbers in iSCSI redirection.
Wait for SCSI status, not just the final data-in (which may be followed
by an explicit SCSI Response PDU if the S bit is not set).
Unconditionally set utility program variables in Makefile to allow CROSS_COMPILE to work.
stappers and xl0 pointed out that gnu make sets some variables, so ?=
is ineffective in some cases where we use it.. Cross-compilation
requires that some variables can be overridden in the
src/$(ARCH)/Config file, so include that file _after_ utility program
variables are set.

Subject: [Etherboot-developers] 3c90x polling again [patch]
Date: Thu, 29 Nov 2007 09:22:36 +0100
User-Agent: Mutt/1.5.16 (2007-06-11)
Hello,
gPXE didn't work on 3COM 905C Tornado cards for me.
It did transmit the DHCP request, but it didn't see the DHCP offer.
Adding debug print statements allready solved the problem.
Attached is a patch that has a cleaner delay then print statements.
The core of it is
- for(i=0;i<40000;i++);
+ mdelay(1);
There was no research if the change is about a longer delay
or about code NOT being optimized away. It works for me :-)
Cheers
