Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.
Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.

Added fields present in the documentation but not in the header file.
2007-01-11 19:41:13 +00:00
dc51af59a4
Capable of starting a multiboot kernel (albeit without the multiboot
...
information table yet).
2007-01-11 18:41:15 +00:00
9196e9069c
Add PHYS_CODE, for use as in __asm__ ( PHYS_CODE ( ... ) ), comparable
...
to the REAL_CODE interface.
2007-01-11 18:40:46 +00:00
d488a172eb
Capable of loading a multiboot image into memory
2007-01-11 17:44:42 +00:00
143e3b84a4
Downloaded from current grub CVS.
2007-01-11 16:22:03 +00:00
4fc9333159
Move include/image.h to include/gpxe/image.h
2007-01-11 16:04:36 +00:00
7ad1c2eaa8
Removed the Etherboot-specific ELF-image code and replaced it with a
...
generic ELF loader, to be used by the multiboot code.
2007-01-11 14:44:03 +00:00
3634e705b7
Remove osloader.c and replace with a prep_segment() that uses userptr_t
...
and get_memmap() in image/segment.c
2007-01-11 14:32:26 +00:00
ceca6b185c
Added user_to_phys() and memset_user().
2007-01-11 14:27:27 +00:00
c980cdd0aa
Move memmap.h out of arch/i386; it no longer contains anything
...
architecture-dependent and is needed by the ELF code.
2007-01-11 14:08:44 +00:00
c6a4055fae
Add phys_to_user() and copy_user().
2007-01-11 14:01:20 +00:00
e2dcd05b67
Update buffer-handling code to enable expandable buffers.
2007-01-11 03:50:47 +00:00
fdc97499bf
Add device description fields to struct device.
2007-01-10 15:27:48 +00:00
489a4004d7
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
18e5353bed
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().
...
This will allow us to implement RX quotas.
2007-01-09 17:04:10 +00:00
aa7bda7b47
Send EOI after enabling interrupt, in case the device had asserted IRQ
...
to the PIC while it was disabled.
2007-01-09 14:53:19 +00:00
a2ffe8c123
Allow boot sector to completely destroy real-mode stack, but still
...
manage to return control.
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().
2007-01-09 14:13:06 +00:00
2738bdf74b
Obsoleted by drivers/net/undionly.c
2007-01-09 03:22:11 +00:00
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
159930862f
Added missing call to undinet_remove()
2007-01-09 03:08:01 +00:00
6b09dd8244
undipci_probe() has to calculate busdevfn anyway, so we may as well pass
...
it directly to undi_load_pci().
2007-01-09 02:58:07 +00:00
ed44e3730d
Avoid erasing non-existent signatures in undi_unload()
2007-01-09 02:53:24 +00:00
a2be828a33
Avoid leaving preloaded_undi with invalid PXENV+/!PXE structure
...
addresses if the signature checks fail.
2007-01-09 02:52:28 +00:00
697bcc9d24
Since we now always unload the base code stack (even if we keep UNDI),
...
we can never return to the PXE stack and must always use INT 18.
2007-01-09 02:46:58 +00:00
f2f492a536
If preloaded device matches, use that rather than going via the UNDI
...
loader.
2007-01-09 02:32:06 +00:00
2436dac281
Populate preloaded_undi device when applicable.
2007-01-09 02:29:54 +00:00
937289cdc8
Provide storage for an undi_device structure representing the preloaded
...
UNDI stack.
2007-01-09 02:29:18 +00:00
47222d5ed8
Call PXENV_UNDI_GET_NIC_TYPE to identify NIC physical device.
...
Record all information required for populating a struct undi_device.
Make debugging output more human-readable.
2007-01-09 01:42:28 +00:00
cea2221737
Use fixed-width fields in struct undi_device, so that pxeprefix.S will be
...
able to populate the structure.
2007-01-09 01:41:26 +00:00
fbdebac5f4
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.
2007-01-08 03:48:26 +00:00
075d79f6d4
Checking in obsolete but working memory-scanning code just for the record
2007-01-08 03:45:00 +00:00

Neaten up debug messages
2007-01-08 03:42:19 +00:00

Now split out into undirom.c and undiload.c
2007-01-08 03:35:51 +00:00
07e5d4e3dc
Added any-PCI-device UNDI driver
2007-01-08 03:34:47 +00:00
66f7bcc785
Tidied up debug messages
2007-01-08 03:34:06 +00:00

359c888aec
Remove obsolete includes
2007-01-08 02:39:56 +00:00
6fc75f659b
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
36c1e1aa57
Renamed undi.c to undinet.c. (undi.c will become the UNDI PCI driver)
2007-01-08 02:02:07 +00:00
234d81728a
Obsolete
2007-01-08 02:00:55 +00:00
d3558fdd3a
Remove accidentally checked-in code
2007-01-07 19:05:28 +00:00
85a41b25fe
Move START_UNDI, UNDI_STARTUP, UNDI_INITIALIZE and
...
UNDI_GET_INFORMATION calls into drivers/net/undi.c. undi_probe() now
gets given a pxe_device representing a PXE stack that has been loaded
into memory but not initialised in any way.
2007-01-07 19:02:17 +00:00
23cb837951
Remember to enable/disable the interrupt at the PIC.
...
Handle failures in undi_open() properly.
2007-01-07 13:31:39 +00:00
9ab5c0dde7
Remove redundant debug message
2007-01-05 16:15:50 +00:00
fa9055197d
UNDI loader routine now works
2007-01-05 16:11:05 +00:00
477a70697a
Added PnP BIOS scanning code, separated out from the UNDI driver
2007-01-05 16:10:03 +00:00
7dee2556f4
Fixed typo
2007-01-05 16:09:47 +00:00
9780fef360
Partial implementation of UNDI loader caller.
2007-01-05 03:24:39 +00:00
0638945c7e
Add PXE driver-scanning code, capable of locating all PXE ROMs in a system
...
and matching them up to (e.g. PCI) devices.
2007-01-05 01:52:06 +00:00
ef50ea0b2b
Renamed undi_net.c to undi.c.
2007-01-04 19:43:35 +00:00
6cf488dcf7
Obsolete; net driver functionality is now in undi_net.c and bus driver
...
functionality is now in pxebus.c. (Not all bus functionality is ported
across yet.)
2007-01-04 19:42:05 +00:00
7e07dfb2f4
Added PXE bus driver (with support only for using PXE structures found
...
lying about in memory, not for loading from ROM), and UNDI net driver.
2007-01-04 19:38:34 +00:00
e28db95de6

This file is no longer used
2007-01-04 19:36:31 +00:00
b12cd68726
Ripped out everything except the ability to send EOI to the PIC.
2007-01-04 19:36:18 +00:00
de2fc50f4c
Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than
...
having to edit PXELOADER_KEEP_ALL as a config option.
2007-01-04 19:35:10 +00:00
290c5ee779
Don't automatically call gateA20_set() when returning from a real-mode
...
call.
2007-01-04 04:32:18 +00:00
f58f193633
Engage brain: since when was zero >= 0x80 ?
2006-12-21 05:15:26 +00:00
9c3b4e5b0b
Some BIOSes return 0xe0 for extended characters. Just assume that
...
anything over 0x80 is an extended character.
2006-12-21 00:07:48 +00:00
dbb7b30cca
Return ANSI sequences for special keys
2006-12-20 23:42:28 +00:00
43d976edd0
Prevent NULL from ever pointing to some real code or data. (This was
...
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).
2006-12-20 20:28:20 +00:00
0aa1223264
Optimise bios_putchar for speed(!) by avoiding two separate real-mode
...
calls. This does make a visible difference when clearing the screen with
werase() inside bochs or qemu.
2006-12-19 01:15:05 +00:00
8b3a4c9862
Add basic ANSI escape sequence support to BIOS console
2006-12-18 01:19:38 +00:00

Fix building on gas versions that don't auto-insert addr32 prefixes
2006-12-12 19:07:18 +00:00
8bff0f0619
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.
2006-12-05 09:45:39 +00:00
88e38fa148
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.
2006-09-27 10:58:14 +00:00
6ac78f6aff
added stdio.h to includes for DBG compilation
2006-09-27 05:57:06 +00:00

2006-09-08 22:22:03 +00:00
78dd963c1f
Check to see if we've reached the end of the map before attempting to
...
skip past an empty region, otherwise we end up generating an infinitely
long e820 map. (Yes, there *are* real systems that provide e820 maps
with a zero-length region at the end...)
2006-08-31 13:25:45 +00:00
5a54225aef
Added support for INT 13,15; NTLDR calls it (though it may not
...
actually do anything with the result, since it carried on using us
even when we returned failure).

a0a872f7f1
Updated PXE UDP implementation to use the new Etherboot UDP API.
...
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)

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.

89da833c5d
init_librm() and prot_call() are now real-mode far calls.

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.

7a53d07027
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,
...
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.
2006-05-23 23:42:45 +00:00
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.).
2006-05-23 23:33:37 +00:00
ca2519cea3
Refactored to reduce code size; now down from 1304 to 1105 bytes.
...
Tidied up debug messages; the log now contains one line per INT 13
operation, looking like
INT 13,08 (80): Get drive parameters
INT 13,02 (80): Read: C/H/S 0/47/14 = LBA 0xb9e <-> 1084:0000 (count 106)
2006-05-20 15:33:32 +00:00
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).
2006-05-19 15:06:51 +00:00
0ab92faedb
Use typeof(sizeof(...)) to define a size_t. This stops gcc complaining

2006-05-19 14:51:59 +00:00
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.)
2006-05-17 01:12:11 +00:00
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).

fdb983d473
Preserve the whole of %esp across prot_call(). We have to split this
...
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:
Just using the stack would screw up when a prot_call()ed routine
executes a real_call(); it would have no way to find the current top of
the RM stack.
Extending rm_sp to rm_esp would not be safe, because the guarantee that
rm_sp must return to the correct value by the time an external
real-mode call returns applies only to %sp, not to %esp.

I want to get to the point where any header in include/ reflects a

header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
