Handle multi-sector reads by splitting them into subcommands.

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! :)

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

used on RTL8139 cards).

Updated to work with libprefix.

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

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

Has been obsolete for a while.

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.

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.

Removed REAL_EXEC(); there is no longer any code using it.

int13_boot() now does its own segment register save and restore, ready

Set carry flag before calling INT 15,e801 and INT 15,e820.
...
Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says
that CF is unreliable for this call.

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.

Replaced memsizes.c with smaller memmap.c, taking advantage of __data16,
...
and creating a memory map that's easier to work with than the E820 map.
2006-05-24 01:37:46 +00:00
5e80847827
Code to install the new E820 mangler (which doesn't require copying
...
down to base memory, since it is now in the base-memory-resident
.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.

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.).
