Michael Brown 5f17089b14 pxe_netdev now holds a reference to the network device. 
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.
 2007-07-02 17:43:32 +01:00
Michael Brown 95cb7aaacf Support cards such as natsemi which treat the data as little-endian 
(i.e. LSB transmitted first on the wire), even though SPI commands and
addresses always have to be big-endian.
 2007-07-01 15:22:12 +01:00

Michael Brown 62548c9f0d Updated 3c509 to current device model 2007-03-10 22:28:22 +00:00
Michael Brown 520d9c36af Updated ISAPnP, EISA, MCA and ISA buses to current device model. 
ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.
 2007-03-10 18:08:33 +00:00
Michael Brown c63af1ea14 Remove no-longer-used variable 2007-02-19 17:31:20 +00:00

James Harper 1c971f1234 Fix padding problem - from Michael 2007-02-10 00:27:46 +00:00
Michael Brown 2cf1e33df1 Split bootsector execution code out into bootsector.c. 
Added basic El Torito ISO image boot capability
 2007-01-29 04:21:38 +00:00
Michael Brown 73b09ecba6 Use stdio.h instead of vsprintf.h 2007-01-19 01:13:12 +00:00
Michael Brown 5ff23aa406 Include stdlib.h rather than malloc.h 2007-01-18 20:06:03 +00:00
Michael Brown 48fe701716 Respect the RX quota. This improves poll time by about 0.7us when the 
quota is 1.
 2007-01-18 12:34:12 +00:00
Michael Brown ff8528ea9a Create and use async_block() macro; it cuts down on the visual overhead 
of blocking on asynchronous operations, when that isn't an important
aspect of the code.
 2007-01-16 08:10:54 +00:00
Michael Brown 4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
 2007-01-15 08:49:10 +00:00
Michael Brown 03390f0cd6 Use pkb_pad() rather than doing it the dangerous way :) 2007-01-11 05:26:16 +00:00
Michael Brown a3ed0cbbc7 Extract packet-padding login from rtl8139.c to a separate pkbpad.c file. 2007-01-11 05:25:50 +00:00
Michael Brown fdc97499bf Add device description fields to struct device. 2007-01-10 15:27:48 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown e822bc2a90 Autopadding was sometimes overwriting the struct list_head at the end 
of the packet buffer.  Although pkbuffs are guaranteed to be at least
PKB_ZLEN bytes long, there's no guarantee that the data starts at the
start of the packet buffer.

Since we have to align data for rtl8139 anyway, and since the start of
the packet buffer is guaranteed to be aligned to PKB_ALIGN, we may as
well just shuffle the packet down so that it starts at the start of
the packet buffer.  This simultaneously aligns the packet and ensures
that there is enough room for the zero-padding.
 2007-01-09 21:01:55 +00:00
Michael Brown 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
Michael Brown 5af4918356 Added support for wildcard device/vendor ID matches 2007-01-08 03:23:38 +00:00
Michael Brown 7b9617f5df Add device to hierarchy before calling the driver's probe() function; this 
way everything remains consistent if the probe() ends up creating child
devices.
 2007-01-08 01:29:51 +00:00
Michael Brown 0c03bb5a9a Make open() and close() an official part of the netdevice API. 
Call netdevice's poll() and transmit() methods only when device is open.
 2007-01-04 04:20:08 +00:00
Michael Brown 61ed298bc7 Merge changes from mcb-tcp-fixes branch. 2006-12-27 23:09:46 +00:00

Michael Brown 9f953322a1 Remove warning (at least on platforms with uint32_t == unsigned long). 2006-12-20 00:34:53 +00:00
Michael Brown a646e38f03 Use stdlib.h for malloc() instead of malloc.h. 2006-12-19 23:42:46 +00:00
Michael Brown a497e16767 The "increment MAC address by port number" hack applies only to EF1. 2006-12-18 15:28:34 +00:00
Michael Brown a39b111684 Automatically select between the "10" and "16" variants of command set, 
based on the device size.
 2006-12-12 18:54:35 +00:00

that some targets send.
 2006-12-12 18:18:54 +00:00

Michael Brown d2bf7abe75 Added write support for three-wire devices (e.g. the RTL8139 EEPROM) 2006-12-06 19:51:58 +00:00
Michael Brown ac401f481d Verify data after writing 2006-12-06 18:51:31 +00:00
Michael Brown a128b33b8b The VPD engine is broken and can't actually handle placing VPD 
anywhere other than offset 0 within the EEPROM, so we have to put our
settings at 0x100 instead.
 2006-12-05 17:56:13 +00:00
Michael Brown 4c3e0fede5 Adjust EEPROM/flash detection to fit expected manufacturing practice. 2006-12-05 16:00:06 +00:00
Michael Brown cb883b3faf Change some debugging messages to use DBG() 2006-12-05 10:01:00 +00:00
Michael Brown 6b45947a59 Added debug statements 2006-12-04 23:20:56 +00:00
Michael Brown 052ef6dc5a Added nvs_write(). This shares a lot of code in common with nvs_read(); 
this can probably be optimised down quite a lot.
 2006-12-04 22:06:54 +00:00
Michael Brown cc9bcb99a0 Add the concept of a fragment list for non-volatile stored options. 2006-12-04 21:46:13 +00:00
Michael Brown f944737045 Fixed two logic errors that were cancelling each other out. 2006-12-04 21:12:52 +00:00
Michael Brown d62c83a350 Migrated etherfabric driver to using generic SPI layer. 2006-12-04 20:47:51 +00:00
Michael Brown 2d8d21fe74 Added the generic block-splitting code to nvs.c 2006-12-04 19:06:07 +00:00
Michael Brown 1961ba44e1 Added generic SPI protocol handler with read and write support. 2006-12-04 18:32:55 +00:00
Michael Brown 946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS 
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.
 2006-12-04 18:23:06 +00:00
Michael Brown dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than 
a word length.
 2006-12-04 16:09:59 +00:00
Michael Brown 931f94dca3 Generalised the SPI abstraction layer to also be able to handle interfaces 
that don't provide the full flexibility of a bit-bashing interface.

Temporarily hacked rtl8139.c to use the new interface.
 2006-12-04 15:36:51 +00:00
Michael Brown 4cd56820ea Basic non-volatile storage support 2006-11-29 02:41:08 +00:00
Michael Brown 3234ef1b0b Merged changes from Solarflare 2006-11-28 13:25:23 +00:00
Michael Brown 3f0b4d9ed8 Updated to use asynchronous operation model for iSCSI requests 
Added CHAP authentication
 2006-11-28 00:29:02 +00:00
Michael Brown 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
Marty Connor 6ac78f6aff added stdio.h to includes for DBG compilation 2006-09-27 05:57:06 +00:00

Michael Brown d393e61d8a Temporary hack to work around the "TX overflow" problem in the interim 
period before updating to the new driver API (which can cope with
having TX packets in progress).
 2006-06-16 14:38:16 +00:00
Michael Brown 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.)

Michael Brown 286bf68faf Added a very quick and dirty compatibility layer, to allow 
not-yet-updated drivers to at least function.
 2006-06-05 15:45:21 +00:00
Michael Brown c3e41e6fd1 Added soon-to-be-requisite missing include. 2006-06-05 15:41:22 +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 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 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 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. 
Increase code simplicity at the expense of around 64 bytes.
 2006-05-28 23:26:42 +00:00
Michael Brown 70ef6dbb7c Rewrote to use the new net driver API, the updated PCI API, and the 
generic three-wire serial device support for EEPROM access.
 2006-05-27 13:45:14 +00:00
Michael Brown aa2468babe Added abstraction layer for a three-wire serial device (e.g. the EEPROM 
used on RTL8139 cards).
 2006-05-26 15:39:24 +00:00
Michael Brown 95956443e1 Fixed debug code 2006-05-21 16:04:41 +00:00
Michael Brown 80958ff69c Added (untested) support for ATA devices. This code should be generic 
enough to support both real IDE chipsets and AoE.
 2006-05-21 16:01:23 +00:00
Michael Brown 4d0a0f822d Use insb/outsb; it's marginally faster. 2006-05-20 12:28:44 +00:00
Michael Brown 402ba15c64 READ CAPACITY (16) turns out to be an optional command (even though 
READ(16) is mandatory); we must use READ CAPACITY (10) first and then
use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".
 2006-05-19 18:54:38 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown 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).
 2006-05-16 15:12:06 +00:00
Michael Brown f25731d08f Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol". 2006-05-14 23:29:16 +00:00

implementation.

Tie into existing driver API; we'll fix that up soon.
 2006-04-24 18:44:50 +00:00
Michael Brown 832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...
 2006-04-24 18:31:37 +00:00
Michael Brown 824d6ffa7f Header rearrangement. 
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
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
definitions.
 2006-04-24 15:42:49 +00:00
Michael Brown fdc2ee79db Network API now allows for multiple network devices (although the 
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.

Michael Brown 487574fc02 This code is unbelievably ugly, has never been fixed up to work with 
relocation and (hence) presumably has not been used since Etherboot 5.0.
Say bye-bye!
 2005-04-14 20:02:10 +00:00

Michael Brown 393969a3f8 Fix up the automatic modifications. 2005-04-14 14:59:04 +00:00
Michael Brown 476dff5bb7 Made amenable to automatic update. 2005-04-14 14:49:32 +00:00
Michael Brown cbd5d4f849 This is the only driver that has a genuine reason to call 
find_pci_device() directly.
 2005-04-14 14:48:07 +00:00
Michael Brown 963dbefb51 Automatically updated using 
perl -pi -0777 -e 's/(_probe\s*\(\s*struct\s+dev.*?)(\s*\)\s*{.*?$)\s*struct pci_device.*?=\s*pci_device \( dev \);$/${1}, struct pci_device *pci${2}/ms' *.c

Michael Brown 9183f2412e bus header files must include dev.h to get struct dev. 2005-04-14 14:26:28 +00:00
Michael Brown e0a8ee385e Updated to current device API. 2005-04-14 13:49:58 +00:00
Michael Brown 104880ca19 Tweak API to allow separation of bus-scanning and device-probing logic. 2005-04-14 13:44:07 +00:00
Michael Brown 4c0d5a0b71 Split 3c509.c into 3c509.9 and 3c529.c, with shared code in 3c5x9.c. 
Probe mechanisms now use standard EISA and MCA bus methods, with 3c509.c
defining a custom ISA bus to handle the 3c509 contention resolution logic.
 2005-04-14 12:23:12 +00:00
Michael Brown 44c7cc8c12 Standardised debug mechanism in place now. 2005-04-14 11:55:57 +00:00

Michael Brown 4ae83f28f2 Don't use htons, for compatibility with PCI :( 2005-04-13 12:15:14 +00:00
Michael Brown 4ecbc63296 Use __bswap_16, since we're not dealing with quantities to go onto the network. 2005-04-13 12:11:21 +00:00
Michael Brown 5b8e549c83 htons was used in ISAPnP code just due to ISAPnP storing bytes in 
reverse order.
 2005-04-13 12:06:33 +00:00
