Since we support SetVariableRT now add the relevant tests - Search for the RTStorageVolatile and VarToFile variables after EBS - Try to update with invalid variales (BS, RT only) - Try to write a variable bigger than our backend storage - Write a variable that fits and check VarToFile...
用于创建、修改和删除启动项(如SetBootEntry()、DeleteBootEntry()、GetBootEntries())。 启动顺序设置(如SetBootOrder())。 启动项的加载和执行(加载 EFI 可执行文件)。 UEFI Runtime Services: 系统重启时,需要将修改后的启动项和配置永久保存在非易失性存储(NVRAM)中。SetVariable()和GetVariable()等 API ...
当加载项其启动失败时,系统将重新执行DXE dispatcher以加载更多的驱动,然后重新尝试加载驱动项。 BDS策略通过全局NVRAM变量配置,这些变量可以被运行时服务的GetVariable()读取,通过SetVariable()设置(如BootOrder定义了启动顺序,Boot###对应不同的启动项,#为十六进制数)。当用户选中某个启动项(或进入系统默认启动项)后...

Having a proxy allows for a model of sharing error- handling code, such as flash access services, with runtime code, such as the EFI Runtime Services GetVariable() or SetVariable(). IA-32 SMM Drivers The IA-32 runtime drivers are not callable from SMM because of the SetVirtualAddress(...
