* [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.
* [virtio] Split virtio-net.c into several files.Laurent Vivier2008-11-192-0/+198

* [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
| | | | | | | With this patch ISA drivers actually get probed so they have a fair chance of working now. Signed-off-by: Pantelis Koukousoulas <pktoss@gmail.com>

* pxe_netdev now holds a reference to the network device.Michael Brown2007-07-022-0/+5
| | | | | | | | | Use generic fields in struct device_description rather than assuming that the struct device * is contained within a pci_device or isapnp_device; this assumption is broken when using the undionly driver. Add PXENV_UNDI_SET_STATION_ADDRESS.
* Updated ISAPnP, EISA, MCA and ISA buses to current device model.Michael Brown2007-03-106-744/+696Star
| | | | | | | ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and MCA (3c529) variants should build OK. None of this code is yet tested.

| | | | | | | | | | | names. Add "dev" pointer in struct net_device to tie network interfaces back to a hardware device. Force natural alignment of data types in __table() macros. This seems to prevent gcc from taking the unilateral decision to occasionally increase their alignment (which screws up the table packing).

* We don't actually have a stdio.h header file. Our printf() functions areMichael Brown2006-09-272-2/+0Star
| | | | | | | | defined in vsprintf.h. (This may change, since vsprintf.h is a non-standard name, but for now it's the one to use.) There should be no need to include vsprintf.h just for DBG() statements, since include/compiler.h forces it in for a debug build anyway.

* Strip down i386 PCI configuration space I/O to the bare minimum. AMichael Brown2006-05-171-11/+4Star
| | | | | | | | | | typical build will now include 880 bytes of PCI support code, compared to 2327 bytes in Etherboot 5.4. (There is a slight cost of around 5 extra bytes per access to a non-constant config space address; this should be an overall win. Driver-specific accesses will usually be to constant addresses, for which there is no additional cost.)
* Restructured PCI subsystem to fit the new device model.Michael Brown2006-05-162-298/+349
| | | | | | | | | | | | | | Generic PCI code now handles 64-bit BARs correctly when setting "membase"; drivers should need to call pci_bar_start() only if they want to use BARs other than the first memory or I/O BAR. Split rarely-used PCI functions out into pciextra.c. Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4). 284 bytes of this saving comes from the pci/pciextra split. Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to match the names used in Linux).
* Header rearrangement.Michael Brown2006-04-241-1/+1
| | | | | | | | | I want to get to the point where any header in include/ reflects a standard user-level header (e.g. a POSIX header), while everything that's specific to gPXE lives in include/gpxe/. Headers that reflect a Linux header (e.g. if_ether.h) should also be in include/gpxe/, with the same name as the Linux header and, preferably, the same names used for the definitions.
