* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-2/+2
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Expose PCI configuration space via settings mechanismMichael Brown2013-07-131-0/+124
| | | | | | | | | | | | | | | | 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. Values are returned in reverse byte order, since PCI configuration space is little-endian by definition. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [isa] Avoid spurious compiler warning on gcc 4.7Michael Brown2012-07-201-3/+3
| | | | | | | | gcc 4.7 produces a spurious warning about an array subscript being out of bounds. Use a pointer dereference instead of an array lookup to inhibit this spurious warning. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [pci] Modularise PCI device supportMichael Brown2011-02-171-47/+79
| | | | | | | | Some operating environments require (or at least prefer) that we do not perform our own PCI bus scan, but deal only with specified devices. Modularise the PCI core to allow for this. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [pci] Use single "busdevfn" field in struct pci_deviceMichael Brown2011-02-171-60/+57Star
| | | | | | | Merge the "bus" and "devfn" fields into a single "busdevfn" field, to match the format used by the majority of external code. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [pci] Allow pci_vpd_init() return status to be ignoredMichael Brown2011-01-191-0/+8
| | | | | | | | Most xxx_init() functions are void functions with no failure cases. Allow pci_vpd_init() to be used in the same way. (Subsequent calls to pci_vpd_read() etc. will fail if pci_vpd_init() fails.) Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [virtio] Replace virtio-net with native iPXE driverStefan Hajnoczi2010-07-171-6/+6
| | | | | | | | | | | | | | | | | | | | | | This patch adds a native iPXE virtio-net driver and removes the legacy Etherboot virtio-net driver. The main reasons for doing this are: 1. Multiple virtio-net NICs are now supported by iPXE. The legacy driver kept global state and caused issues in virtual machines with more than one virtio-net device. 2. Faster downloads. The native iPXE driver downloads 100 MB over HTTP in 12s, the legacy Etherboot driver in 37s. This simple benchmark uses KVM with tap networking and the Python SimpleHTTPServer both running on the same host. Changes to core virtio code reduce vring descriptors to 256 (QEMU uses 128 for virtio-blk and 256 for virtio-net) and change the opaque token from u16 to void*. Lowering the descriptor count reduces memory consumption. The void* opaque token change makes driver code simpler.

* [build] Rename gPXE to iPXEMichael Brown2010-04-2010-21/+21
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [pci] Save and restore PCI command registerBernhard Kohl2010-01-221-0/+5
| | | | | | | | | | | This seems to be necessary for some types of PCI devices. We had problems when using gPXE in KVM virtual machines with direct PCI device access.

* [pci] Add generic configuration space backup/restore facilityMichael Brown2009-10-141-0/+90
| | | | | | Some devices can only be reset via a mechanism that also resets the card's PCI core, thus necessitating a backup and restore of all or part of the PCI configuration space across a reset.
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-186-0/+12
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-135-30/+5Star
| | | | | | | | | | | | | | | Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.
* [pci] Enable memory cycles in adjust_pci_device()Michael Brown2008-12-121-1/+2
| | | | | | | adjust_pci_device() has historically enabled bus-mastering and I/O cycles, but has never previously needed to enable memory cycles. Some EFI systems seem not to enable memory cycles by default, so add that to the list of PCI command register bits that we force on.

* [i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] longMichael Brown2008-11-192-2/+2
| | | | | | 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.
* [isa] Fix a small typo in isa.c.Pantelis Koukousoulas2008-11-081-2/+2
