* [smsc75xx] Add driver for SMSC/Microchip LAN75xx USB Ethernet NICsMichael Brown2015-03-111-0/+1
| | | | | | | | | | | | | | | | | | | This driver is functional but any downloads via a TCP-based protocol tend to perform poorly. The 1Gbps Ethernet line rate is substantially higher than the 480Mbps (in practice around 280Mbps) provided by USB2, and the device has only 32kB of internal buffer memory. Our 256kB TCP receive window therefore rapidly overflows the RX FIFO, leading to multiple dropped packets (usually within the same TCP window) and hence a low overall throughput. Reducing the TCP window size so that the RX FIFO does not overflow greatly increases throughput, but is not a general-purpose solution. Further investigation is required to determine how other OSes (e.g. Linux) cope with this scenario. It is possible that implementing TCP SACK would provide some benefit.

* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+1
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [efi] Add NII / UNDI driverMichael Brown2014-10-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Some UEFI network drivers provide a software UNDI interface which is exposed via the Network Interface Identifier Protocol (NII), rather than providing a Simple Network Protocol (SNP). The UEFI platform firmware will usually include the SnpDxe driver, which attaches to NII and provides an SNP interface. The SNP interface is usually provided on the same handle as the underlying NII device. This causes problems for our EFI driver model: when efi_driver_connect() detaches existing drivers from the handle it will cause the SNP interface to be uninstalled, and so our SNP driver will not be able to attach to the handle. The platform firmware will eventually reattach the SnpDxe driver and may attach us to the SNP handle, but we have no way to prevent other drivers from attaching first. Fix by providing a driver which can attach directly to the NII protocol, using the software UNDI interface to drive the network device. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Wrap any images loaded by our wrapped imageMichael Brown2014-08-291-0/+1
| | | | | | | | | | | | Propagate our modified EFI system table to any images loaded by the image that we wrap, thereby allowing us to observe boot services calls made by all subsequent EFI images. Also show details of intercepted ExitBootServices() calls. When wrapping is used, exiting boot services will almost certainly fail, but this at least allows us to see when it happens.

* [console] Add centralised concept of colours and colour pairsMichael Brown2013-12-091-0/+2
| | | | | | | | | | | | | Add a centralised concept of colours and colour pairs (using the default colour pairs as configured via config/colour.h). A colour pair consists of a pair of colour indices. Add the ability to redefine both a colour pair and an individual colour index, with minimal overhead if this feature is not required (e.g. because the relevant shell commands are not present in the build).

* [dhcpv6] Add basic support for stateful and stateless DHCPv6Michael Brown2013-11-141-0/+1
| | | | | | | | | | | | Add support for the stateful and stateless variants of the DHCPv6 protocol. The resulting settings block is registered as "net<x>.dhcpv6", and DHCPv6 options can be obtained using e.g. "${net0.dhcpv6/23:ipv6}" to obtain the IPv6 DNS server address. IPv6 addresses obtained via stateful DHCPv6 are not yet applied to the network device. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Expose memory map via settings mechanismMichael Brown2013-08-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow memory map entries to be read using the syntax ${memmap/<region>.<properties>.<scale>} where <region> is the index of the memory region, <properties> is a bitmask where bit 0 represents the start address and bit 1 represents the length (allowing the end address to be encoded by having both bits 0 and 1 set), and <scale> is the number of bits by which to shift the result. This allows for several values of interest to be encoded. For example: ${memmap/<region>.1.0:hexraw} # 64-bit start address of <region> ${memmap/<region>.2.0:hexraw} # 64-bit length of <region>, in bytes ${memmap/<region>.3.0:hexraw} # 64-bit end address of <region> ${memmap/<region>.2.10:int32} # Length of <region>, in kB ${memmap/<region>.2.20:int32} # Length of <region>, in MB The numeric encoding is slightly more sophisticated than described here, allowing a single encoding to cover multiple regions. (See the source code for details.) The primary use case for this feature is to provide the total system memory size (in MB) via the "memsize" predefined setting.

* [settings] Expose PCI configuration space via settings mechanismMichael Brown2013-07-131-0/+1
| | | | | | | | | | | | | | | | Allow values to be read from PCI configuration space using the syntax ${pci/<busdevfn>.<offset>.<length>} where <busdevfn> is the bus:dev.fn address of the PCI device (expressed as a single integer, as returned by ${net0/busloc}), <offset> is the offset within PCI configuration space, and <length> is the length within PCI configuration space.

* [pending] Add concept of "pending operations"Michael Brown2012-06-091-0/+1
| | | | | | | | | | iPXE is fundamentally asynchronous in operation: some operations continue in the background even after the foreground has continued to a new task.
