Michael Brown 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.

Michael Brown 73b09ecba6 Use stdio.h instead of vsprintf.h 2007-01-19 01:13:12 +00:00
Michael Brown f547f148d3 Use {get,set}_fbms() so that allocated base memory is correctly hidden. 2007-01-14 00:01:16 +00:00
Michael Brown d0f4e9a54b Add some trace messages for important events 2007-01-13 17:54:41 +00:00
Michael Brown 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.

Michael Brown 5817c9f114 When an UNDI API call fails, print everything there is to know about it. 2007-01-13 16:53:55 +00:00
Michael Brown 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.

Michael Brown f81bf3bc52 We *do* have a __data16_array after all! 2007-01-12 02:37:47 +00:00
Michael Brown fdc97499bf Add device description fields to struct device. 2007-01-10 15:27:48 +00:00
Michael Brown 489a4004d7 Give UNDI device a more meaningful name. 2007-01-10 05:52:04 +00:00
Michael Brown 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).

Michael Brown 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
Michael Brown 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
Michael Brown 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
Michael Brown 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
Michael Brown 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
Michael Brown 2738bdf74b Obsoleted by drivers/net/undionly.c 2007-01-09 03:22:11 +00:00
Michael Brown 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).
 2007-01-09 03:20:22 +00:00
Michael Brown 159930862f Added missing call to undinet_remove() 2007-01-09 03:08:01 +00:00
Michael Brown 6b09dd8244 undipci_probe() has to calculate busdevfn anyway, so we may as well pass 
it directly to undi_load_pci().
 2007-01-09 02:58:07 +00:00
Michael Brown ed44e3730d Avoid erasing non-existent signatures in undi_unload() 2007-01-09 02:53:24 +00:00
Michael Brown f2f492a536 If preloaded device matches, use that rather than going via the UNDI 
loader.
 2007-01-09 02:32:06 +00:00
Michael Brown 937289cdc8 Provide storage for an undi_device structure representing the preloaded 
UNDI stack.
 2007-01-09 02:29:18 +00:00
Michael Brown cea2221737 Use fixed-width fields in struct undi_device, so that pxeprefix.S will be 
able to populate the structure.
 2007-01-09 01:41:26 +00:00
Michael Brown 075d79f6d4 Checking in obsolete but working memory-scanning code just for the record 2007-01-08 03:45:00 +00:00
Michael Brown 67e824b539 Neaten up debug messages 2007-01-08 03:42:19 +00:00
Michael Brown f08093b0d9 Remove spurious debug message 2007-01-08 03:37:32 +00:00
Michael Brown f0edd11c7d Now split out into undirom.c and undiload.c 2007-01-08 03:35:51 +00:00
Michael Brown 07e5d4e3dc Added any-PCI-device UNDI driver 2007-01-08 03:34:47 +00:00
Michael Brown 66f7bcc785 Tidied up debug messages 2007-01-08 03:34:06 +00:00
Michael Brown afc01a1a7f Split UNDI load/unload out into undiload.c. 2007-01-08 02:48:17 +00:00
Michael Brown 359c888aec Remove obsolete includes 2007-01-08 02:39:56 +00:00
Michael Brown 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).
 2007-01-08 02:38:10 +00:00
Michael Brown 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.
 2007-01-08 02:24:53 +00:00
Michael Brown 36c1e1aa57 Renamed undi.c to undinet.c. (undi.c will become the UNDI PCI driver) 2007-01-08 02:02:07 +00:00
Michael Brown 234d81728a Obsolete 2007-01-08 02:00:55 +00:00
Michael Brown d3558fdd3a Remove accidentally checked-in code 2007-01-07 19:05:28 +00:00
Michael Brown 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.
 2007-01-07 19:02:17 +00:00
Michael Brown 23cb837951 Remember to enable/disable the interrupt at the PIC. 
Handle failures in undi_open() properly.
 2007-01-07 13:31:39 +00:00
Michael Brown 9ab5c0dde7 Remove redundant debug message 2007-01-05 16:15:50 +00:00
Michael Brown fa9055197d UNDI loader routine now works 2007-01-05 16:11:05 +00:00
Marty Connor 7dee2556f4 Fixed typo 2007-01-05 16:09:47 +00:00
Michael Brown 9780fef360 Partial implementation of UNDI loader caller. 2007-01-05 03:24:39 +00:00
Michael Brown 0638945c7e Add PXE driver-scanning code, capable of locating all PXE ROMs in a system 
and matching them up to (e.g. PCI) devices.
 2007-01-05 01:52:06 +00:00
Michael Brown ef50ea0b2b Renamed undi_net.c to undi.c. 2007-01-04 19:43:35 +00:00
Michael Brown 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
Michael Brown 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.
 2007-01-04 19:38:34 +00:00
Marty Connor c4964c3e3a fix args to _disable routine 2006-09-19 15:01:16 +00:00
Michael Brown 52125e158c Will be replaced with a block-device implementation. 2006-05-24 13:52:46 +00:00
Michael Brown 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.
