51d62d1a3c Provide a mechanism for returning the encapsulator as well as the 
encapsulated option; this will be needed for modifications to the options
block.

0bcaa8a21f First stab at DHCP option handling in a way that will allow us to have 
multiple option sources (e.g. multiple DHCP replies, non-volatile
storage etc.)

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.

ab4f96e525 Move per-transition delays from generic bit-bashing layer to i2c layer 
(since SPI bit-bashing will require different delay semantics).

286bf68faf Added a very quick and dirty compatibility layer, to allow

d78581297b Improve tcpdump legibility. 2006-06-01 19:23:52 +00:00

48fb6c6dc2 Updated retry timer mechanism to incorporate smoothed RTT estimation. 
AoE now uses the retry timer mechanism.

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
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).

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()).

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!  :)

6f998cecb3 Use separate data-in and data-out buffers. 
Increase code simplicity at the expense of around 64 bytes.

f743de4858 Added tcp_kick(). This speed up LILO and GRUB booting by almost two 
orders of magnitude.

6c50564724 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

aa2468babe Added abstraction layer for a three-wire serial device (e.g. the EEPROM 
used on RTL8139 cards).

3204a1e941 Removed some obsolete INIT_XXX constants. 2006-05-25 01:09:06 +00:00

bef8874842 - implemented printw (formatted string output, a la printf) 
- implemented hline/vline (part of wborder family)
- screen cursor now relocates at same time as window cursor when
  restoring after a non-wrapping function
 2006-05-22 17:03:41 +00:00
Michael Brown
84a493b88d Allow vcprintf() to be called by external code such as the curses library. 
Also trim another eight bytes from vsprintf.o.  :)

f778500739 - fixes to _wputch to get positioning and wrap working properly 
- fixes to wborder (same)

9dfb9d84b4 Made the LBA48 example clearer. 2006-05-21 16:02:38 +00:00
Michael Brown
80958ff69c Added (untested) support for ATA devices. This code should be generic 
enough to support both real IDE chipsets and AoE.

402ba15c64 READ CAPACITY (16) turns out to be an optional command (even though 
READ(16) is mandatory); we must use READ CAPACITY (10) first and then
use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".

444b885a7d Add EOVERFLOW==ERANGE 2006-05-19 18:53:12 +00:00
Dan Lynch
acf572905c - made some of the bit shifting attribute access simpler (in my mind) 
- added extern declarations for global vars
- removed comments from static inlines (too time consuming to do them
  all, considering all so far have been due to the ridiculous amount of
  redundancy within the API spec)
- removed a few more extern func decls for funcs that cannot be
  implemented at this time
