* [build] Mark core files as permitted for UEFI Secure BootMichael Brown2026-01-142-0/+2
| | | | | | | | | | | | Mark all files used in a standard build of bin-x86_64-efi/snponly.efi as permitted for UEFI Secure Boot. These files represent the core functionality of iPXE that is guaranteed to have been included in every binary that was previously subject to a security review and signed by Microsoft. It is therefore legitimate to assume that at least these files have already been reviewed to the required standard multiple times. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Mark Ip4Config.h as a non-imported headerMichael Brown2025-11-111-0/+5
| | | | | | | | | | | | The Ip4Config.h header has been removed from the EDK2 codebase as obsolete. However, we may still encounter it in the wild and so it is useful to retain the GUID and the corresponding protocol name for debug messages. Add an iPXE include guard to this file so that the EDK2 header import script will no longer attempt to import it from the EDK2 tree. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | | | | | The UsbHostController.h header has been removed from the EDK2 codebase since it was never defined in a released UEFI specification. However, we may still encounter it in the wild and so it is useful to retain the GUID and the corresponding protocol name for debug messages. Add an iPXE include guard to this file so that the EDK2 header import script will no longer attempt to import it from the EDK2 tree. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | The EFI service binding abstraction is used to add and remove child handles for multiple different protocols. Provide a common interface for doing so. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Provide a multiprocessor API for EFIMichael Brown2024-03-151-0/+676
| | | | | | | | | | | | | Provide an implementation of the iPXE multiprocessor API for EFI, based on using EFI_MP_SERVICES to start up a wrapper function on all application processors. Note that the processor numbers used by EFI_MP_SERVICES are opaque integers that bear no relation to the underlying CPU identity (e.g. the APIC ID), and so we must rely on our own (architecture- specific) implementation to determine the relevant CPU identifiers.

| | | | | | | | | The UEFI shim includes a "shim lock protocol" that can be used by a third party second stage loader such as GRUB to verify a kernel image. Add definitions for the relevant portions of this protocol interface. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Mark AppleNetBoot.h as a native iPXE headerMichael Brown2016-10-161-3/+3
| | | | | | | | | AppleNetBoot.h is not taken from the EDK2 codebase and so cannot be imported using include/ipxe/efi/import.pl. Mark as a native iPXE header (by changing the include guard) to avoid breaking the import process. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Expose DHCP packets via the Apple NetBoot protocolMichael Brown2016-05-291-0/+46

* [efi] Use a timer event to generate the currticks() timerMichael Brown2016-05-041-302/+0Star
| | | | | | | | | | | | | | We currently use the EFI_CPU_ARCH_PROTOCOL's GetTimerValue() method to generate the currticks() timer, calibrated against a 1ms delay from the boot services Stall() method. This does not work on ARM platforms, where GetTimerValue() is an empty stub which just returns EFI_UNSUPPORTED. Fix by instead creating a periodic timer event, and using this event to increment a current tick counter. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Use the EFI_RNG_PROTOCOL as an entropy source if availableMichael Brown2015-04-141-0/+158
| | | | | | | | | | | | | | | Entropy gathering via timer ticks is slow under UEFI (of the order of 20-30 seconds on some machines). Use the EFI_RNG_PROTOCOL if available, to speed up the process of entropy gathering. Note that some implementations (including EDK2) will fail if we request fewer than 32 random bytes at a time, and that the RNG protocol provides no guarantees about the amount of entropy provided by a call to GetRNG(). We take the (hopefully pessimistic) view that a 32-byte block returned by GetRNG() will contain at least the 1.3 bits of entropy claimed by min_entropy_per_sample().

* [efi] Include EFI_CONSOLE_CONTROL_PROTOCOL headerMichael Brown2014-07-161-0/+124
| | | | | | | | | | | | The EFI_CONSOLE_CONTROL_PROTOCOL does not exist in the current UEFI specification, but is required to enable text output on some older EFI 1.10 implementations (observed on an old iMac). The header is not present in any of the standard include directories, but can still be found in the EDK2 codebase as part of EdkCompatibilityPkg. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [efi] Install our own disk I/O protocol and claim exclusive use of itMichael Brown2014-07-141-0/+119
| | | | | | | | | | | | | | | | | | | The EFI FAT filesystem driver has a bug: if a block device contains no FAT filesystem but does have an EFI_SIMPLE_FILE_SYSTEM_PROTOCOL instance, the FAT driver will assume that it must have previously installed the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. This causes the FAT driver to claim control of our device, and to refuse to stop driving it, which prevents us from later uninstalling correctly. Work around this bug by opening the disk I/O protocol ourselves, thereby preventing the FAT driver from opening it. Note that the alternative approach of opening the block I/O protocol (and thereby in theory preventing DiskIo from attaching to the block I/O protocol) causes an endless loop of calls to our DRIVER_STOP method when starting the EFI shell. I have no idea why this is. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [efi] Expose downloaded images via EFI_SIMPLE_FILE_SYSTEM_PROTOCOLMichael Brown2013-03-132-0/+646
| | | | | | | | | | | | | | | | | 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>
