Experimentation reveals that gcc ignores -mrtd for the implicit

(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

Declaring the CPU architecture in the middle of an assembly file is

Always send EOI. We can't feasibly share interrupts (since we have no

clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts. Joy.

f59ad50504
Provide registration mechanism for loaded images, so that we can e.g.

refer to them by name from the command line, or build them into a
multiboot module list.
Use setting image->type to disambiguate between "not my image" and "bad

2007-01-11 14:32:26 +00:00
ceca6b185c

2007-01-11 14:27:27 +00:00
c980cdd0aa
Move memmap.h out of arch/i386; it no longer contains anything

Give UNDI device a more meaningful name.
2007-01-10 05:52:04 +00:00
dad5274522
Add "name" field to struct device to allow human-readable hardware device
...
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).
2007-01-10 04:22:09 +00:00
c65fae2475
Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.
2007-01-09 21:47:01 +00:00

Rename pkb_available() to pkb_tailroom() for consistency with Linux's
...
skb_tailroom(). Add pkb_headroom().
2007-01-09 20:56:31 +00:00
b7fcfe8ece
Added net device TX queue; this will be needed to support the PXE UNDI API
...
(which will need us to wait for TX completions).
Added debug autocolourisation to netdevice.c
2007-01-09 20:18:31 +00:00
3c2cc59d25
Added ability to break ISR processing over several calls to poll().

2007-01-09 14:13:59 +00:00
a9369bb503
Leave protected-mode return address on PM stack when issuing a

real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack
contents, provided that it manages to return to real_call().

d606edb41d
Added UNDI root bus driver (which saves including all the PCI bus code,
...
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).
This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).
2007-01-09 03:20:22 +00:00

2007-01-09 02:52:28 +00:00
697bcc9d24
Since we now always unload the base code stack (even if we keep UNDI),

Copy pxelinux's shutdown sequence: use UNLOAD_STACK without STOP_BASE,

and call UNDI_SHUTDOWN first to make sure the NIC is in a safe state.
2007-01-08 05:06:26 +00:00
8f8af10b22
New strategy: always stop both base code and UNDI. Always free base code

memory (unless we get an error while stopping the base code). Leave UNDI
resident (though stopped) for .kpxe.
Still need to add code to record the device identification parameters
prior to stopping UNDI.

Separated out UNDI ROM location code into undirom.c, and use struct

undi_rom rather than struct pxe_driver. (This is part of the naming
consistency fixes).
2007-01-08 02:38:10 +00:00
675fe200e5
Use "struct undi_device" instead of "struct pxe_device", and use the
...
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.
The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.
2007-01-08 02:24:53 +00:00

Optimise bios_putchar for speed(!) by avoiding two separate real-mode

Avoid draining the keyboard buffer during gateA20_set(). It shouldn't
...
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty). See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.
gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems. In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.
We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.

We don't actually have a stdio.h header file. Our printf() functions are
...
defined in vsprintf.h. (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)
There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

Allow our functions to return a non-zero, non-error status (since the

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

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.
