[netdevice] Separate out the concept of hardware and link-layer addresses

2009-08-11T23:19:14+00:00

The hardware address is an intrinsic property of the hardware, while the link-layer address can be changed at runtime. This separation is exposed via APIs such as PXE and EFI, but is currently elided by gPXE. Expose the hardware and link-layer addresses as separate properties within a net device. Drivers should now fill in hw_addr, which will be used to initialise ll_addr at the time of calling register_netdev().

[netdevice] Make ll_broadcast per-netdevice rather than per-ll_protocol

2009-07-17T22:02:48+00:00

IPoIB has a link-layer broadcast address that varies according to the partition key. We currently go through several contortions to pretend that the link-layer address is a fixed constant; by making the broadcast address a property of the network device rather than the link-layer protocol it will be possible to simplify IPoIB's broadcast handling.

[legal] Add a selection of FILE_LICENCE declarations

2009-05-18T07:33:25+00:00

Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.

[pci] Add driver_data field to struct pci_device_id

[i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] long

2008-11-19T19:15:44+00:00

This brings us in to line with Linux definitions, and also simplifies adding x86_64 support since both platforms have 2-byte shorts, 4-byte ints and 8-byte long longs.

[phantom] Do not halt PEGs on driver shutdown

2008-11-08T05:10:23+00:00

Halting the PEGs breaks platforms where there is sideband access to the NIC (e.g. HP machines using iLO). (We have to retain the unhalting code because on some other platforms (e.g. IBM blades with BOFM) the pre-PXE firmware must halt the PEGs to avoid issues with the BIOS rereading via the expansion ROM BAR.)

[phantom] Allow for PXE boot to be enabled/disabled on a per-port basis

2008-11-01T01:55:13+00:00

This is something of an ugly hack to accommodate an OEM requirement. The NIC has only one expansion ROM BAR, rather than one per port. To allow individual ports to be selectively enabled/disabled for PXE boot (as required), we must therefore leave the expansion ROM always enabled, and place the per-port enable/disable logic within the gPXE driver.

[phantom] Assume one net device per PCI function

2008-10-31T01:55:58+00:00

The Phantom firmware selectively disables PCI functions based on the board type, with the end result that we see one PCI function for each network port. This allows us to eliminate the code for reading from flash and, more importantly, removes knowledge of the board type magic number from the gPXE driver.

[settings] Add the notion of a "tag magic" to numbered settings

2008-10-30T21:47:14+00:00

Settings can be constructed using a dotted-decimal notation, to allow for access to unnamed settings. The default interpretation is as a DHCP option number (with encapsulated options represented as ".". In several contexts (e.g. SMBIOS, Phantom CLP), it is useful to interpret the dotted-decimal notation as referring to non-DHCP options. In this case, it becomes necessary for these contexts to ignore standard DHCP options, otherwise we end up trying to, for example, retrieve the boot filename from SMBIOS. Allow settings blocks to specify a "tag magic". When dotted-decimal notation is used to construct a setting, the tag magic value of the originating settings block will be ORed in to the tag number. Store/fetch methods can then check for the magic number before interpreting arbitrarily-numbered settings.

[phantom] Add CLP settings interface

2008-10-28T18:49:58+00:00

This interface provides access to firmware settings (e.g. MAC address) that will apply to all drivers loaded for the duration of the current system boot.
