* [ata] Make ATA command issuing partially asynchronousMichael Brown2009-07-171-1/+24
| | | | | | | | | Move the icky call to step() from aoe.c to ata.c; this takes it at least one step further away from where it really doesn't belong. Unfortunately, AoE has the ugly aoe_discover() mechanism which means that we still have a step() loop in aoe.c for now; this needs to be replaced at some future point.

* [netdevice] Add netdev argument to link-layer push and pull handlersJoshua Oreman2009-06-231-2/+6
| | | | | | | | | | | | | | | In order to construct outgoing link-layer frames or parse incoming ones properly, some protocols (such as 802.11) need more state than is available in the existing variables passed to the link-layer protocol handlers. To remedy this, add struct net_device *netdev as the first argument to each of these functions, so that more information can be fetched from the link layer-private part of the network device. Updated all three call sites (netdevice.c, efi_snp.c, pxe_undi.c) and both implementations (ethernet.c, ipoib.c) of ll_protocol to use the new argument.

* [spi] Add address-length autodetection to the SPI bit-bashing codeMichael Brown2009-05-282-18/+86
| | | | | | | | | | | Several SPI chips will respond to an SPI read command with a dummy zero bit immediately prior to the first real data bit. This can be used to autodetect the address length, provided that the command length and data length are already known, and that the MISO data line is tied high.

* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-135-30/+5
| | | | | | | | | | | | | | | 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.
* [sundance] Add reset completion checkThomas Miletich2009-02-271-0/+16

* [scsi] Cope with targets that send multiple CHECK CONDITIONS at power-onMichael Brown2009-01-301-5/+19
| | | | | | | | | | | | | | | Some targets send a spurious CHECK CONDITION message in response to the first SCSI command. We issue (and ignore the status of) an arbitary harmless SCSI command (a READ CAPACITY (10)) in order to draw out this response. The Solaris Comstar target seems to send more than one spurious CHECK CONDITION response. Attempt up to SCSI_MAX_DUMMY_READ_CAP dummy READ CAPACITY (10) commands before assuming that error responses are meaningful. Problem reported by Kristof Van Doorsselaere <kvandoor@aserver.com> and Shiva Shankar <802.11e@gmail.com>.
* [infiniband] Call ib_open() only when opening the IPoIB net deviceMichael Brown2009-01-023-0/+20
| | | | | Defer the call to ib_open() until we want to actually open the device, rather than when the device is registered.
* [etherfabric] Make use of pci_bar_start() 64-bit cleanMichael Brown2008-12-121-2/+3
| | | | | | | | Driver was storing the result of pci_bar_start() and pci_bar_size() in an int, rather than an unsigned long. (Bug was introduced in the vendor's tree in commit eac85cd "Port etherfabric driver to net_device api".)
* [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.
* [e1000] Use PCI_BASE_ADDRESS_* symbols instead of integersMarty Connor2008-12-051-2/+2
| | | | | | | | | | | When compiling for the Linux kernel, PCI_BASE_ADDRESS_0 == 0, and PCI_BASE_ADDRESS_1 == 1. This is not so when compiling for gPXE. We must use the symbolic names rather than integers to get the correct values. Bug identified and patch supplied by: George Chou <george.chou@advantech.com>

* [b44] Add driver for Broadcom bcm44xx cardsPantelis Koukousoulas2008-11-212-0/+1416
| | | | | | | | | | | | | | | | | | This driver is based on Stefan Hajnoczi's summer work, which is in turn based on version 1.01 of the linux b44 driver. I just assembled the pieces and fixed/added a few pieces here and there to make it work for my hardware. The most major limitation is that this driver won't work on systems with >1GB RAM due to the card not having enough address bits for that and gPXE not working around this limitation. Still, other than that the driver works well enough for at least 2 users :) and the above limitation can always be fixed when somebody wants it bad enough :) Signed-off-by: Pantelis Koukousoulas <pktoss@gmail.com>

* [infiniband] Respect hop pointer when building directed route SMP return pathMichael Brown2008-11-122-46/+60
| | | | | | | | | | | | The return path in directed route SMPs lists the egress ports in order from SM to node, rather than from node to SM. To write to the correct offset within the return path, we need to parse the hop pointer. This is held within the class-specific data portion of the MAD header, which was previously unused by us and defined to be a uint16_t. Define this field to be a union type; this requires some rearrangement of ib_mad.h and corresponding changes to ipoib.c.
* [linda] Add support for QLogic 7220-based Infiniband HCAsMichael Brown2008-11-115-0/+5558
| | | | | | | | | These cards very nearly support our current IB Verbs model. There is one minor difference: multicast packets will always be delivered by the hardware to QP0, so the driver has to redirect them to the appropriate QP. This means that QP owners may see receive completions for buffers that they never posted. Nothing in our current codebase will break because of this.
* [infiniband] Add raw packet parser and constructorMichael Brown2008-11-111-0/+234
| | | | | | | This can be used with cards that require the driver to construct and parse packet headers manually. Headers are optionally handled out-of-line from the packet payload, since some such cards will split received headers into a separate ring buffer.
* [infiniband] Add a standalone subnet management agentMichael Brown2008-11-111-0/+541
| | | | | This generic SMA code can be used for any cards that do not provide firmware-based embedded SMAs.
* [ipoib] Kill off the IPoIB pseudo-headerMichael Brown2008-11-111-109/+197
| | | | | | | | | Some Infiniband cards will not be as accommodating as the Arbel and Hermon cards in providing enough space for us to push a fake extra header at the start of the received packet. We must therefore make do with squeezing enough information to identify source and destination addresses into the two bytes of padding within a genuine IPoIB link-layer header.
* [infiniband] Split subnet management agent client out into ib_smc.cMichael Brown2008-11-114-100/+278
| | | | | | | | Not all Infiniband cards have embedded subnet management agents. Split out the code that communicates with such an embedded SMA into a separate ib_smc.c file, and have drivers call ib_smc_update() explicitly when they suspect that the answers given by the embedded SMA may have changed.
* [infiniband] Pass address vector in receive completionsMichael Brown2008-11-113-104/+101
| | | | | | | | | | | | | | | | | Receive completion handlers now get passed an address vector containing the information extracted from the packet headers (including the GRH, if present), and only the payload remains in the I/O buffer. This breaks the symmetry between transmit and receive completions, so remove the ib_completer_t type and use an ib_completion_queue_operations structure instead. Rename the "destination QPN" and "destination LID" fields in struct ib_address_vector to reflect its new dual usage. Since the ib_completion structure now contains only an IB status code, ("syndrome") replace it with a generic gPXE integer status code.
* [infiniband] Maintain queue fill level as a property of a work queueMichael Brown2008-11-111-11/+4
| | | | | Both queue owners and drivers often need to keep track of the fill level, so let's make it a generic property.
