* [linker] Add mechanism for subsystem-dependent configuration optionsJoshua Oreman2009-11-211-238/+0Star
| | | | | | | | | | | | | | | | | | | | It is often the case that some module of gPXE is only relevant if the subsystem it depends on is already being included. For instance, commands to manage wireless interfaces are quite useless if no compiled-in driver has pulled in the wireless networking stack. There may be a user-modifiable configuration options for these dependent modules, but even if enabled, they should not be included when they would be useless. Solve this by allowing the creation of config_subsystem.c, for configuration directives like those in the global config.c that should only be considered when subsystem.c is included in the final gPXE build. For consistency, move core/config.c to the config/ directory, where the other config_subsystem.c files will eventually reside. Signed-off-by: Marty Connor <mdc@etherboot.org>
* [infiniband] Add support for SRP over InfinibandMichael Brown2009-08-101-0/+3
| | | | | | | | SRP is the SCSI RDMA Protocol. It allows for a method of SAN booting whereby the target is responsible for reading and writing data using Remote DMA directly to the initiator's memory. The software initiator merely sends and receives SCSI commands; it never has to touch the actual data.
* [pxe] Add startpxe and stoppxe commandsMichael Brown2009-06-281-0/+3
| | | | | | | | | These commands can be used to activate or deactivate the PXE API (on a specifiable network interface). This is currently of limited use, since most image formats will call shutdown() before booting the image, meaning that the underlying net device gets shut down during remove_devices() anyway.
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.

* [image] Allow multiple embedded imagesMichael Brown2009-02-161-0/+1
| | | | | | | | | | This patch extends the embedded image feature to allow multiple embedded images instead of just one. gPXE now always boots the first embedded image on startup instead of doing the hardcoded DHCP boot (aka autoboot). Based heavily upon a patch by Stefan Hajnoczi <stefanha@gmail.com>.
* [efi] Add EFI image format and basic runtime environmentMichael Brown2008-10-131-0/+6
| | | | | | | | | We have EFI APIs for CPU I/O, PCI I/O, timers, console I/O, user access and user memory allocation. EFI executables are created using the vanilla GNU toolchain, with the EXE header handcrafted in assembly and relocations generated by a custom efilink utility.

* [iSCSI] Support Windows Server 2008 direct iSCSI installationMichael Brown2008-07-171-0/+7
| | | | | | | | | | | | | Add yet another ugly hack to iscsiboot.c, this time to allow the user to inhibit the shutdown/removal of the iSCSI INT13 device (and the network devices, since they are required for the iSCSI device to function). On the plus side, the fact that shutdown() now takes flags to differentiate between shutdown-for-exit and shutdown-for-boot means that another ugly hack (to allow returning via the PXE stack on BIOSes that have broken INT 18 calls) will be easier. I feel dirty.
* [GDB] Remote debugging over UDPStefan Hajnoczi2008-06-301-1/+8
| | | | | | | | | | | | | | | | | This commit implements GDB over UDP. Using UDP is more complex than serial and has required some restructuring. The GDB stub is now built using one or both of GDBSERIAL and GDBUDP config.h options. To enter the debugger, execute the gPXE shell command: gdbstub <transport> [<options>...] Where <transport> is "serial" or "udp". For "udp", the name of a configured network device is required: gdbstub udp net0 The GDB stub listens on UDP port 43770 by default.
* [ELF] Add ability to boot ELF images generated by wraplinux and mkelfImageMichael Brown2008-06-091-4/+1Star
| | | | | | | | | | | | | | | | | | | Delete ELF as a generic image type. The method for invoking an ELF-based image (as well as any tables that must be set up to allow it to boot) will always depend on the specific architecture. core/elf.c now only provides the elf_load() function, to avoid duplicating functionality between ELF-based image types. Add arch/i386/image/elfboot.c, to handle the generic case of 32-bit x86 ELF images. We don't currently set up any multiboot tables, ELF notes, etc. This seems to be sufficient for loading kernels generated using both wraplinux and coreboot's mkelfImage. Note that while Etherboot 5.4 allowed ELF images to return, we don't. There is no callback mechanism for the loaded image to shut down gPXE, which means that we have to shut down before invoking the image. This means that we lose device state, protection against being trampled on, etc. It is not safe to continue afterwards.

* [GDBSYM] Remove unused gdbsym.cStefan Hajnoczi2008-06-051-3/+0Star
| | | | | | The GDBSYM config.h option was an attempt at QEMU GDB debugging. I have removed the code since it is unused and may confuse people wanting to use the GDB stub.

Some driver are using currticks, which is only for core subsystems. Signed-off-by: Alexey Zaytsev <alexey.zaytsev@gmail.com>
