transition away from uIP.

Prepared ipv4.c for transition away from uIP.

3c8aafa209 Simplify RX data path. 
Kill off the static single net device and move to proper dynamic
registration (which we need with the new device model).

Break the (flawed) assumption that all network-layer protocols can use
ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP
protocol using ARP_NET_PROTOCOL() and provide a single method for checking
the existence of a local network-layer address.

d393e61d8a Temporary hack to work around the "TX overflow" problem in the interim 
period before updating to the new driver API (which can cope with
having TX packets in progress).

52de4935f9 Add 4 bytes to maximum frame length to allow for the frame checksum. 
(This actually matters once you try using TCP, because you *will*
receive full-sized frames.)

bcdcd796fb 32kB window is actually larger than our typical receive ring size. 
Shrink to 4kB for now.  We might want to see if it can be made
genuinely indicative of the RX ring size in the new TCP
implementation.

17eea9f933 Fix bug with >256 cylinders. 
Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).

Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.

763b7e2ef9 We now have just romprefix, rather than having isaprefix and pciprefix 2006-06-06 15:41:21 +00:00
Michael Brown
ef37f78cbe Cut out almost all the optional code paths, drastically simplifying the 
flow of control through this code.

We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.

UNDI loader is still missing.

50415b3aca Make DBG_DISCARD correct 2006-06-01 12:11:09 +00:00
Michael Brown
1f394c2f7c Backing out last change; no immediate plans to make the whole block-device 
layer asynchronous, so keeping the sync/async boundary within aoedev.c
seems cleanest for now.
 2006-06-01 11:14:59 +00:00
Michael Brown
d6866202f9 Until we have a functioning UDP stack and PXE API again, there's not much 
point trying to use the old boot sequence.  Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.
 2006-06-01 11:07:31 +00:00
Michael Brown
d21fc3610f Added sample AoE test code to tree 2006-06-01 11:05:36 +00:00
Michael Brown
f6d20bb0f4 Put in a method to get the MAC address for the AoE target. (It's not 
elegant, but it works).
 2006-05-31 19:12:17 +00:00

99ef98d0bf ATA devices are now asynchronous. The ATA layer itself now performs the 
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous.  (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).

cf96d325d8 Missing from previous checkin. 
This is the core portion of the async I/O interface.
 2006-05-31 18:45:43 +00:00
Michael Brown
68125bc441 Added generic asynchronous operations code. 
Removed data_in_len and data_out_len from ata_command structure; the
lengths are implied by the sector count and the presence of the data_in
or data_out pointers.

Changed AoE code to use subcommands by default, and made aoe_issue()
nonblocking (with completion via async_wait()).
 2006-05-31 14:34:17 +00:00

73a449e96b Added drivers/ata directory (forgot to check this in previously). 2006-05-31 14:31:48 +00:00

552b4a178e One bit of an ASCII character can make a big difference. 2006-05-29 21:00:00 +00:00
Michael Brown
1db1a6dad3 Added first sketch of a generic retry timer mechanism. The idea is to use 
these timer objects in AoE and UDP protocols (where there is no underlying
retransmission mechanism) without requiring each protocol to implement its
own individual retry logic.  Eventually, we should be able to use the same
timer code for TCP retransmissions as well.

6541338897 Handle multi-sector reads by splitting them into subcommands. 2006-05-29 08:25:31 +00:00
Michael Brown
9a2a52693d Initial AoE implementation. Limitations are: 
Cannot yet handle reads of more than two sectors

  No retransmission

  No way to find out a target's MAC address (this proof of concept uses
  broadcasts)

These limitations shall not last long!  :)
 2006-05-28 23:29:43 +00:00

6f998cecb3 Use separate data-in and data-out buffers.

70ef6dbb7c Rewrote to use the new net driver API, the updated PCI API, and the 
generic three-wire serial device support for EEPROM access.

6c50564724 Make PKB_ZLEN the minimum possible size of packet buffer (to allow for 
hardware that can't autopad).

9f86754f90 Updated to work with libprefix. 2006-05-25 22:04:47 +00:00
Michael Brown
29340d7728 Documented the fact that the prefix can prot_call(main) without 
worrying about its stack being destroyed during the Etherboot run.

0479e9f541 relocate.o is now dragged in by the objects that require it; there is no

d82f71efd0 Also hide base memory region from E820 map. 2006-05-25 00:10:58 +00:00
Michael Brown
89da833c5d init_librm() and prot_call() are now real-mode far calls. 
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().
 2006-05-25 00:06:45 +00:00
Michael Brown
4d81b48504 Has been obsolete for a while. 2006-05-25 00:04:37 +00:00
Michael Brown
1966945a5d Update relocate() to work with get_memmap(). 
Change semantics; relocate() now just finds a suitable location; it
doesn't actually perform the relocation itself.  Code in libprefix does
the copy in flat real mode.
