[bios] Add bin-x86_64-pcbios build platform

2016-02-16T19:32:32+00:00

Move most arch/i386 files to arch/x86, and adjust the contents of the Makefiles and the include/bits/*.h headers to reflect the new locations. This patch makes no substantive code changes, as can be seen using a rename-aware diff (e.g. "git show -M5"). This patch does not make the pcbios platform functional for x86_64; it merely allows it to compile without errors. Signed-off-by: Michael Brown

[pxe] Notify BIOS via INT 1a,564e for each new network device

2015-09-15T12:43:35+00:00

Use INT 1a,564e to notify the BIOS of each network device that we detect. This provides an opportunity for the BIOS to implement platform policy such as changing the MAC address by issuing a call to PXENV_UNDI_SET_STATION_ADDRESS. Signed-off-by: Michael Brown

[pxe] Invoke INT 1a,564e when PXE stack is activated

2015-09-15T12:33:44+00:00

Invoke INT 1a,564e whenever a PXE stack is activated, passing the address of the PXENV+ structure in %es:%bx. This is designed to allow a BIOS to be notified when a PXE stack has been installed, providing an opportunity for start-of-day commands such as setting the MAC address according to a policy chosen by the BIOS. PXE defines INT 1a,5650 as a means of locating the PXENV+ structure: this call returns %ax=0x564e and the address of the PXENV+ structure in %es:%bx. We choose INT 1a,564e as a fairly natural notification call, using the parameters as would be returned by INT 1a,5650. The full calling convention (documented as per section 3.1 of the PXE specification) is: INT 1a,564e - PXE installation notification Enter: %ax = 0x564e %es = 16-bit segment address of the PXENV+ structure %bx = 16-bit offset of the PXENV+ structure Exit: %edx may be trashed (as is the case for INT 1a,5650) All other register contents must be preserved CF is cleared IF is preserved All other flags are undefined Signed-off-by: Michael Brown

[uri] Generalise tftp_uri() to pxe_uri()

2015-09-02T12:38:53+00:00

Merge the functionality of parse_next_server_and_filename() and tftp_uri() into a single pxe_uri(), which takes a server address (IPv4/IPv6/none) and a filename, and produces a URI using the rule: - if the filename is a hierarchical absolute URI (i.e. includes a scheme such as "http://" or "tftp://") then use that URI and ignore the server address, - otherwise, if the server address is recognised (according to sa_family) then construct a TFTP URI based on the server address, port, and filename - otherwise fail.

[pxe] Construct all fake DHCP packets before starting PXE NBP

2015-08-29T15:58:12+00:00

Commit edf74df ("[pxe] Always reconstruct packet for PXENV_GET_CACHED_INFO") fixed the problems caused by returning stale DHCP packets (e.g. from an earlier boot attempt using a different network device), but broke interoperability with NBPs such as WDS which may overwrite our cached (fake) DHCP packets and expect the modified packets to be returned by a subsequent call to PXENV_GET_CACHED_INFO. Fix by constructing the fake DHCP packets immediately before transferring control to a PXE NBP. Calls to PXENV_GET_CACHED_INFO will now never modify the cached packets. Signed-off-by: Michael Brown
