Legacy drivers will not pad when necessary
2006-06-05 16:10:36 +00:00
7826de3f7e
PNIC doesn't auto-pad.
2006-06-05 16:10:14 +00:00
286bf68faf
Added a very quick and dirty compatibility layer, to allow
...
not-yet-updated drivers to at least function.
2006-06-05 15:45:21 +00:00
c3e41e6fd1
Added soon-to-be-requisite missing include.

Improve tcpdump legibility.

Quick hack to avoid trying to use an uninitialised net device.
2006-06-01 15:53:05 +00:00

Updated retry timer mechanism to incorporate smoothed RTT estimation.
...
AoE now uses the retry timer mechanism.
2006-06-01 14:33:52 +00:00
50415b3aca
Make DBG_DISCARD correct
2006-06-01 12:11:09 +00:00
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
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
d21fc3610f
Added sample AoE test code to tree
2006-06-01 11:05:36 +00:00
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

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).
2006-05-31 18:57:11 +00:00
cf96d325d8
Missing from previous checkin.
...
This is the core portion of the async I/O interface.
2006-05-31 18:45:43 +00:00
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).

One bit of an ASCII character can make a big difference.
2006-05-29 21:00:00 +00:00

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.
2006-05-29 14:55:07 +00:00

Handle multi-sector reads by splitting them into subcommands.
2006-05-29 08:25:31 +00:00
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.
...
Increase code simplicity at the expense of around 64 bytes.
2006-05-28 23:26:42 +00:00

Added tcp_kick(). This speed up LILO and GRUB booting by almost two
...
orders of magnitude.

Avoid causing TX overflow on small TX queues.

Rewrote to use the new net driver API, the updated PCI API, and the
...
generic three-wire serial device support for EEPROM access.
2006-05-27 13:45:14 +00:00

I have no idea how this ever worked before.

Make PKB_ZLEN the minimum possible size of packet buffer (to allow for
...
hardware that can't autopad).
2006-05-27 13:39:45 +00:00

Tidied up debugging messages

Added abstraction layer for a three-wire serial device (e.g. the EEPROM
...
used on RTL8139 cards).
2006-05-26 15:39:24 +00:00

Need write permission to /dev/net/tun, not just read.

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

relocate.o is now dragged in by the objects that require it; there is no
...
need for a CONFIG_RELOCATE.
2006-05-25 01:34:13 +00:00
3204a1e941
Removed some obsolete INIT_XXX constants.
2006-05-25 01:09:06 +00:00

Also hide base memory region from E820 map.
2006-05-25 00:10:58 +00:00
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
4d81b48504
Has been obsolete for a while.
2006-05-25 00:04:37 +00:00
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.
2006-05-25 00:04:13 +00:00

Why should pushal/popal put the registers on the stack in a logical

order?

Typo.

Add a "count" field to struct memory_map.
2006-05-25 00:00:30 +00:00
986f6ffff1
Define a struct memory_map with a fixed number of entries, rather than
...
requiring each caller to decide how many entries it wants to permit.
2006-05-24 14:41:27 +00:00
edcf89e2b0
Remove the automatic segment register save and restore; most users of

REAL_CODE() don't need it.
2006-05-24 14:11:36 +00:00

Removed REAL_EXEC(); there is no longer any code using it.
2006-05-24 14:10:15 +00:00
