* [efi] Disable SNP devices when running iPXE as the applicationMichael Brown2014-03-141-7/+126
| | | | | | | | | | | | | Some UEFI builds will set up a timer to continuously poll any SNP devices. This can drain packets from the network device's receive queue before iPXE gets a chance to process them. Use netdev_rx_[un]freeze() to explicitly indicate when we expect our network devices to be driven via the external SNP API (as we do with the UNDI API on the standard BIOS build), and disable the SNP API except when receive queue processing is frozen.

* [settings] Allow for multiple definitions of each predefined settingMichael Brown2013-12-051-0/+4
| | | | | | | | | | Allow for multiple setting definitions with the same name but different scopes and tags. For example, allow for a "filename" setting with default scope and tag value 67 (for DHCPv4) and a corresponding "filename" setting with IPv6 scope and tag value 59 (for DHCPv6).

* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-2/+6
| | | | | | | | | | 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>

* [efi] Add our own EFI_LOAD_FILE_PROTOCOL implementationMichael Brown2013-03-141-1/+56
| | | | | | | | | | | | | When iPXE is used as a UEFI driver, the UEFI PXE base code currently provides the TCP/IP stack, network protocols, and user interface. This represents a substantial downgrade from the standard BIOS iPXE user experience. Fix by installing our own EFI_LOAD_FILE_PROTOCOL implementation which initiates the standard iPXE boot procedure. This upgrades the UEFI iPXE user experience to match the standard BIOS iPXE user experience. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Expose downloaded images via EFI_SIMPLE_FILE_SYSTEM_PROTOCOLMichael Brown2013-03-132-21/+607
| | | | | | | | | | | | | | | | | Expose iPXE's images as a UEFI file system, allowing the booted image to access all images downloaded by iPXE. This functionality is complementary to the custom iPXE download protocol. The iPXE download protocol allows a booted image to utilise iPXE to download arbitrary URIs, but requires the booted image to specifically support the custom iPXE download protocol. The new functionality limits the booted image to accessing only files that were already downloaded by iPXE (e.g. as part of a script), but can work with any generic UEFI image (e.g. the UEFI shell). Both protocols are provided simultaneously, and are attached to the SNP device handle. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Delegate to child device's EFI_COMPONENT_NAME2_PROTOCOL, if presentMichael Brown2012-11-211-5/+22
| | | | | | | | | | EFI's device naming model requires drivers to provide names for child devices. Allow the driver's GetControllerName() method to delegate to an instance of EFI_COMPONENT_NAME2_PROTOCOL installed on the child device itself (if present); this allows the SNP device to expose its own device name via the PCI driver's GetControllerName() method.

* [efi] Provide guaranteed space in transmitted packetsMichael Brown2012-09-141-6/+7
| | | | | | | | | | | | | eIPoIB requires space to expand a transmitted ARP packet. This guarantee is met by ensuring that a transmitted packet consists of at least MAX_LL_HEADER_LEN bytes from the start of the I/O buffer up to the end of the link-layer header, and at least IOB_ZLEN bytes thereafter. Adjust the I/O buffer allocation for SNP transmitted packets to ensure that this guarantee is met. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [ipoib] Expose Ethernet-compatible eIPoIB link-layer addresses and headersMichael Brown2012-08-311-1/+2
| | | | | | | | | | | | | Almost all clients of the raw-packet interfaces (UNDI and SNP) can handle only Ethernet link layers. Expose an Ethernet-compatible link layer to local clients, while remaining compatible with IPoIB on the wire. This requires manipulation of ARP (but not DHCP) packets within the IPoIB driver. This is ugly, but it's the only viable way to allow IPoIB devices to be driven via the raw-packet interfaces. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Work around platforms which choke on EFI_PCI_DEVICE_ENABLEMichael Brown2012-05-161-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | EFI_PCI_DEVICE_ENABLE is a list of the standard attributes that must be enabled for a PCI device to function: I/O cycles, memory cycles, and bus-mastering. We currently call EFI_PCI_IO_PROTOCOL::Attribute() with the parameter EFI_PCI_DEVICE_ENABLE to enable a PCI device. This should translate to a single write to PCI configuration space. Simplicity is not a virtue within the UEFI world. Some platforms will 'helpfully' report an error if EFI_PCI_DEVICE_ENABLE is used on a device that doesn't actually support all three of the relevant attributes. For example, if a PCI device provides only memory-mapped accesses (and so hardwires the I/O enable bit to zero), then using EFI_PCI_DEVICE_ENABLE on such a platform will result in an EFI_UNSUPPORTED error. There is no plausible use case in which it is useful for the platform to return an error in this way, and doing so makes it impossible to distinguish genuine errors from noise. Work around this broken behaviour by attempting to enable the three attributes individually, and ignoring any errors. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Update link state in SNP device mode dataMichael Brown2012-04-191-2/+15
| | | | | | | | | | | There is no explicit SNP API call to determine link state; the SNP interface user may check the MediaPresent field within the mode data at any time. Update the MediaPresent field whenever the link state changes. Reported-by: Michael R Turner <mikeyt@us.ibm.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [console] Allow usage to be defined independently for each consoleMichael Brown2012-03-261-0/+8
| | | | | | | | | | | | | | | | | | | | | Add the concept of a "console usage", such as "standard output" or "debug messages". Allow usages to be associated with each console independently. For example, to send debugging output via the serial port, while preventing it from appearing on the local console: #define CONSOLE_SERIAL CONSOLE_USAGE_ALL #define CONSOLE_PCBIOS ( CONSOLE_USAGE_ALL & ~CONSOLE_USAGE_DEBUG ) If no usages are explicitly specified, then a default set of usages will be applied. For example: #define CONSOLE_SERIAL will have the same affect as #define CONSOLE_SERIAL CONSOLE_USAGE_ALL Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Add iPXE download protocolJarrod Johnson2012-02-151-0/+233
| | | | | | | | | | | | | iPXE exposes some extended capabilities via the PXE FILE API to allow NBPs such as pxelinux to use protocols other than TFTP. Provide an equivalent interface as a UEFI protocol so that EFI binaries may also take advantage of iPXE's extended capabilities.

* [efi] Mark SNP devices as children of EFI PCI deviceMichael Brown2011-03-152-0/+64
| | | | | | | | | | | | | Re-open the EFI_PCI_IO_PROTOCOL specifying an Attributes value of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER. This causes the SNP devices to be marked as children of the EFI PCI device (as shown in the "devtree" command). On at least one IBM blade system, this is required in order to have the relevant drivers automatically attach to the SNP controller at device creation time.

| | | | | | | | | | | | | | EFI performs its own PCI bus enumeration. Respect this, and start controlling devices only when instructed to do so by EFI. As a side benefit, we should now correctly create multiple SNP instances for multi-port devices. This should also fix the problem of failing to enumerate devices because the PCI bridges have not yet been enabled at the time the iPXE driver is loaded. Signed-off-by: Michael Brown <mcb30@ipxe.org>
