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
Michael Brown f33f01c126 Defined SCSI device interface, and added SCSI block device 
implementation.
 2006-05-13 11:37:50 +00:00
Michael Brown 79f64eea55 Transmit the buffer contents, not the buffer descriptor... 2006-04-28 14:08:41 +00:00
Michael Brown fcf765e42d Add missing {register,free}_netdev(). 
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.
