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.

Temporary hack to work around the "TX overflow" problem in the interim

Add 4 bytes to maximum frame length to allow for the frame checksum.

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

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.

Backing out last change; no immediate plans to make the whole block-device

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

2006-06-01 11:07:31 +00:00

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).
2006-05-31 18:57:11 +00:00

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

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

init_librm() and prot_call() are now real-mode far calls.

install() now calls relocate(), moves the protected-mode code to the new

2006-05-25 00:06:45 +00:00

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.

Set carry flag before calling INT 15,e801 and INT 15,e820.

Split out REAL_CODE() from REAL_EXEC(), preparatory to removing REAL_EXEC

completely.
2006-05-24 09:51:04 +00:00
83d80d9e79
Remove references to obsoleted REAL_CALL from documentation.
2006-05-24 09:16:48 +00:00
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.
2006-05-24 09:14:44 +00:00
77a65075a6
Replaced memsizes.c with smaller memmap.c, taking advantage of __data16,

5e80847827
Code to install the new E820 mangler (which doesn't require copying

.text16 section).
2006-05-23 23:47:05 +00:00
897313007b
Add __{text,data}16_array, since there's no way I can see to make the

usual __{text,data}16 trick work with arrays. gcc seems to accept the
__asm__ ( asmlabel ) only after the [] of the array declaration, not
before.
