* [hw] Eliminate polling while waiting for window to openMichael Brown2011-06-281-1/+2
| | | | | | | | | | | | | | | Polling for the data-transfer window to become open is wasteful. We can eliminate the polling loop by using hw_step() as the handler for an xfer_window_changed() event. If the window is already open at the time of instantiation, then xfer_window_changed() may never be called. We can cover this case by using hw_step() as the step() method of a one-shot process. Since the signature for an xfer_window_changed() method is identical to the signature for a process step() method, the same function can be used for both.

* [process] Add support for one-shot processesMichael Brown2011-06-282-2/+24
| | | | | | | | | Some processes execute only once, and exist solely in order to defer execution until after the relevant instantiator method has returned. Such processes do not need to be automatically rescheduled when executing. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [process] Pass containing object pointer to process step() methodsMichael Brown2011-06-2816-101/+229
| | | | | | | | | Give the step() method a pointer to the containing object, rather than a pointer to the process. This is consistent with the operation of interface methods, and allows a single function to serve as both an interface method and a process step() method.

* [xfer] Send xfer_window_changed() after xfer_vredirect()Michael Brown2011-06-281-1/+16
| | | | | | | | | | Modify the default action for xfer_vredirect() to automatically send xfer_window_changed() messages to both the new child and the parent interfaces. This will allow the elimination of processes that simply poll on xfer_window() to determine when a redirection has completed successfully. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [ftp] Remove redundant ftp_data_deliver() methodMichael Brown2011-06-281-25/+4Star
| | | | | | | | ftp_data_deliver() does nothing except pass through the received data to the xfer interface, and so can be eliminated by using a pass-through interface. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [prefix] Cope with BOOT_IMAGE= anywhere within command lineMichael Brown2011-06-281-4/+14

* [ipv4] Record ARP resolution errorsMichael Brown2011-06-281-0/+2
| | | | | | | | | At the time of attempting ARP resolution, we already know the transmitting network device. We can therefore record ARP errors using netdev_tx_err() so that they show up in the output of "ifstat".

* [romprefix] Force PnP header to a 16-byte boundary for IBM BIOSesMichael Brown2011-05-171-0/+5
| | | | | | | | | | IBM BIOSes ignore the PnP header offset stored at address 0x1a and instead scan for the $PnP signature on a 16-byte boundary. (This alignment is not mandated by the PnP specification.) Force PnP header to a 16-byte boundary to work around these BIOSes. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [romprefix] Do not fall back to hooking INT19 by defaultMichael Brown2011-05-172-0/+8
| | | | | | | | | | | | | | | | | | | | Several BIOSes (including most IBM BIOSes and many virtual machine BIOSes) do not provide detectable PnP support, but will use the BEV entry point for a PnP option ROM. On these semi-PnP BIOSes, iPXE will respond to the absence of detectable PnP support by hooking INT19, which disrupts the boot order. BIOSes that genuinely require hooking INT19 seem to be very rare nowadays. It may therefore be preferable to assume that the absence of detectable PnP support indicates a semi-PnP BIOS rather than a non-PnP BIOS. Change the default behaviour so that INT19 will never be hooked unless the compile-time option NONPNP_HOOK_INT19 is enabled. Leave the redundant PnP detection routine in-place to allow for debugging via the ROM banner line. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [ipv4] Include network device metadata in packet tracesMichael Brown2011-05-051-3/+10
| | | | | | | | | | | | | | | | | (Ab)use the "ident" field in transmitted IPv4 packets to convey metadata about the network device. In particular: bits 0-3 represent the low bits of the "RX" good packet counter bits 4-7 represent the low bits of the "RXE" bad packet counter bits 8-15 represent the transmitted packet sequence number This allows some relevant information about the internal state of the network device to be read out from a packet trace from a non-debug build of iPXE. In particular, it allows a packet trace containing packets transmitted by iPXE to indicate whether or not any packets have been received by iPXE. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [bofm] Report {slot,port} to {bus:dev.fn,mport} mapping on newer BOFM buildsMichael Brown2011-05-041-2/+7
| | | | | | | | | | | | | Newer BOFM builds provide support for mapping multiple physical ports to a single PCI bus:dev.fn via PCI VPD descriptions. These builds will also leave the {slot,port} field intact, and will populate the mport field with a meaningful value. Older BOFM builds will zero out the {slot,port} field. A zero value in this field may indicate either a genuine zero value (i.e. slot 0 first port) or an older build. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [romprefix] Attempt to gracefully handle semi-PnP IBM BIOSesMichael Brown2011-05-041-6/+20
| | | | | | | | | | | Some IBM BIOSes provide partial support for PnP: they will use the BEV entry point but will not advertise PnP support. This causes iPXE to hook INT 19, which disrupts the boot process. Attempt to improve this situation by detecting an IBM BIOS and treating it as a PnP BIOS despite the absence of a PnP signature.

* [build] Fix building on mildly deranged versions of binutilsMichael Brown2011-04-291-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some versions of binutils have curious concepts of what constitutes subtraction. For example: 0x00000000000000f0 _text16_late = . 0x0000000000000898 _mtext16 = . 0x0000000000000898 _etext16 = . 0x0000000000000898 _text16_late_filesz = ABSOLUTE ((_mtext16 - _text16_late)) 0x00000000000007a8 _text16_late_memsz = ABSOLUTE ((_etext16 - _text16_late)) This has interesting side-effects such as producing sizes for .bss segments that are negative, causing the majority of addressable memory to be zeroed out. Fix by using the form ABSOLUTE ( x ) - ABSOLUTE ( y ) rather than ABSOLUTE ( x - y ) Reported-by: H. Peter Anvin <hpa@zytor.com> Suggested-by: H. Peter Anvin <hpa@zytor.com> Tested-by: H.
