[build] Mark core files as permitted for UEFI Secure Boot

2026-01-14T13:25:34+00:00

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

[pci] Allow probing permission to vary by range

2025-11-24T23:16:32+00:00

Make pci_can_probe() part of the runtime selectable PCI I/O API, and defer this check to the per-range API. Signed-off-by: Michael Brown

[pci] Use linker tables for runtime selectable PCI APIs

2025-11-24T20:54:01+00:00

Use the linker table mechanism to enumerate the underlying PCI I/O APIs, to allow PCIAPI_CLOUD to become architecture-independent code. Signed-off-by: Michael Brown

[bios] Use generic external heap based on the system memory map

[bios] Describe umalloc() heap as an in-use memory area

2025-05-16T15:18:36+00:00

Use the concept of an in-use memory region defined as part of the system memory map API to describe the umalloc() heap. Signed-off-by: Michael Brown

[bios] Update to use the generic system memory map API

2025-05-16T15:18:36+00:00

Provide an implementation of the system memory map API based on the assorted BIOS INT 15 calls, and a temporary implementation of the legacy get_memmap() function using the new API. Signed-off-by: Michael Brown

[acpi] Remove userptr_t from ACPI table parsing

2025-04-22T13:21:06+00:00

Simplify the ACPI table parsing code by assuming that all table content is fully accessible via pointer dereferences. Signed-off-by: Michael Brown

[efi] Centralise definition of efi_cpu_nap()

2024-09-13T13:38:23+00:00

Define a cpu_halt() function which is architecture-specific but platform-independent, and merge the multiple architecture-specific implementations of the EFI cpu_nap() function into a single central efi_cpu_nap() that uses cpu_halt() if applicable. Signed-off-by: Michael Brown

[pci] Separate permission to probe buses from bus:dev.fn range discovery

2024-08-15T08:31:14+00:00

The UEFI device model requires us to not probe the PCI bus directly, but instead to wait to be offered the opportunity to drive devices via our driver service binding handle. We currently inhibit PCI bus probing by having pci_discover() return an empty range when using the EFI PCI I/O API. This has the unwanted side effect that scanning the bus manually using the "pciscan" command will also fail to discover any devices. Separate out the concept of being allowed to probe PCI buses from the mechanism for discovering PCI bus:dev.fn address ranges, so that this limitation may be removed. Signed-off-by: Michael Brown

[cpuid] Allow reading hypervisor CPUID leaves

2024-08-01T11:49:48+00:00

Hypervisors typically intercept CPUID leaves in the range 0x40000000 to 0x400000ff, with leaf 0x40000000 returning the maximum supported function within this range in register %eax. iPXE currently masks off bit 30 from the requested CPUID leaf when checking to see if a function is supported, which causes this check to read from leaf 0x00000000 instead of 0x40000000. Fix by including bit 30 within the mask. Signed-off-by: Michael Brown
