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

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.

ab4f96e525 Move per-transition delays from generic bit-bashing layer to i2c layer

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.

286bf68faf Added a very quick and dirty compatibility layer, to allow 
not-yet-updated drivers to at least function.

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
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).
 2006-05-31 18:57:11 +00:00
Michael Brown
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
Michael Brown
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
Michael Brown
6f998cecb3 Use separate data-in and data-out buffers.

70ef6dbb7c Rewrote to use the new net driver API, the updated PCI API, and the

29340d7728 Documented the fact that the prefix can prot_call(main) without

89da833c5d init_librm() and prot_call() are now real-mode far calls. 
install() now calls relocate(), moves the protected-mode code to the new

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.

83d80d9e79 Remove references to obsoleted REAL_CALL from documentation. 2006-05-24 09:16:48 +00:00
Michael Brown
3b525385af Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is 
the only one we actually use).  This allows REAL_EXEC fragments to
contain proper references to constraints (e.g. "%w0"), rather than having
to force the use of specific registers.

Note that the "num_constraints" parameter is now completely obsolete, and
that we can probably reduce the syntax to something like
  __asm__ __volatile__ ( REAL_CODE ( "asm statements" )
                         : output constraints
                         : input constraints
                         : clobber );
which would look much more natural, and avoid the need to always specify
a clobber list.


Add userptr_t to libkir.h, to allow it to at least compile.

before.

5ec2b2c251 Cope with regions bigger than 4GB. 
We now split e820 regions around ourselves, rather than just
truncating the e820 region.  This avoids the worst-case scenario of
losing all memory over 4GB.

It's more important to get the memory map right now that we're
expecting to still be loaded when the OS starts in several situations
(e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).

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)

  implemented at this time

d48d0fb1bb Add the concept of a "user pointer" (similar to the void __user * in 
the kernel), which encapsulates the information needed to refer to an
external buffer.  Under normal operation, this can just be a void *
equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent.

Use this concept to avoid the need for bounce buffers in int13.c,
which reduces memory usage and opens up the possibility of using
multi-sector reads.

Extend the block-device API and the SCSI block device implementation
to support multi-sector reads.

Update iscsi.c to use user buffers.

Move the obsolete portions of realmode.h to old_realmode.h.

MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds
from power-up to C:> prompt in bochs).

6b6096d28b Strip down i386 PCI configuration space I/O to the bare minimum. A 
typical build will now include 880 bytes of PCI support code, compared to
2327 bytes in Etherboot 5.4.

(There is a slight cost of around 5 extra bytes per access to a
non-constant config space address; this should be an overall win.
Driver-specific accesses will usually be to constant addresses, for
which there is no additional cost.)

15ee09ed10 Restructured PCI subsystem to fit the new device model. 
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).
