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.

4b77061881 Pick up the return status code from the correct place now that we
don't overwrite the parameter block until *after* the debug code.

6a3c76c8e0 Always send EOI. We can't feasibly share interrupts (since we have no
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts.  Joy.

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).

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.

18e5353bed Rename pkb_available() to pkb_tailroom() for consistency with Linux's
skb_tailroom().  Add pkb_headroom().

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

3c2cc59d25 Added ability to break ISR processing over several calls to poll().
This will allow us to implement RX quotas.

aa7bda7b47 Send EOI after enabling interrupt, in case the device had asserted IRQ
to the PIC while it was disabled.

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).

6b09dd8244 undipci_probe() has to calculate busdevfn anyway, so we may as well pass
it directly to undi_load_pci().

cea2221737 Use fixed-width fields in struct undi_device, so that pxeprefix.S will be
able to populate the structure.

6fc75f659b Separated out UNDI ROM location code into undirom.c, and use struct
undi_rom rather than struct pxe_driver.  (This is part of the naming
consistency fixes).

675fe200e5 Use "struct undi_device" instead of "struct pxe_device", and use the
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.

The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.

85a41b25fe Move START_UNDI, UNDI_STARTUP, UNDI_INITIALIZE and
UNDI_GET_INFORMATION calls into drivers/net/undi.c.  undi_probe() now
gets given a pxe_device representing a PXE stack that has been loaded
into memory but not initialised in any way.

6cf488dcf7 Obsolete; net driver functionality is now in undi_net.c and bus driver
functionality is now in pxebus.c.  (Not all bus functionality is ported
across yet.)
2007-01-04 19:42:05 +00:00

7e07dfb2f4 Added PXE bus driver (with support only for using PXE structures found
lying about in memory, not for loading from ROM), and UNDI net driver.

824d6ffa7f Header rearrangement.
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.
