Efi dxe driver

Protocol. This section will introduce how to produce and consume protocols. The UEFI Specification defines a group of boot services to handle protocols, including: First, to make use of it, the module writer must declare the protocols for the module in the INF and then write code to use the protocols. // Handle for new protocol instance.  · Solved by writing driver that suggest to run an app. Idea to create event and catching EVT_SIGNAL_EXIT_BOOT_SERVICES wouldn't work because after this [actually after ExitBootServices()] event several fields of the EFI System Table should be set to NULL. The acronym DXE stands for Driver eXecution Environment and begins after the Pre-EFI Initialization (PEI) phase or in the presence of a valid Hand-Off Block (HOB) list. The DXE phase consists of a few components, DXE Core, DXE Dispatcher, and DXE drivers. The Core component is responsible for producing a set of Boot Services, DXE, Services, and.

DXE drivers that require read-only access or read/write access to volatile environment variables must have EFI_VARIABLE_ARCH_PROTOCOL in their dependency expressions. DXE drivers that require write access to nonvolatile environment variables must have the EFI_VARIABLE_WRITE_ARCH_PROTOCOL in their dependency expressions. The two parameters for the DXE driver entry point are ImageHandle and SystemTable. ImageHandle refers to the image handle of the DXE driver. SystemTable points to the EFI System Table. The acronym DXE stands for Driver eXecution Environment and begins after the Pre-EFI Initialization (PEI) phase or in the presence of a valid Hand-Off Block (HOB) list.
