首先,efi_stub_entry在调用该方法时,寄存器rdi, rsi, rdx里的值都没有改变,还是efi_pe_entry调用efi_stub_entry时传递的那些值,所以根据上述calling convention,efi_main作为efi_stub_entry的被调用函数,其参数类型及顺序也应该和efi_pe_entry的参数传递顺序是一样的。 这个可以从上面代码里得到确认。 接着,efi_...
在拷贝完setup header之后,该函数又设置了boot_params里的setup header的root_flags、boot_flag、cmdline等字段。 在boot_params里的setup_header都初始化完毕之后,该函数最终调用了efi_stub_entry函数,并将参数image handle,system table,和boot params传递给了它。 至此,efi_pe_entry函数就结束了。 如果熟读过uefi ...
Failed to add the EFI boot entry on Guest Hey folks, Trying to install some debian UEFI guests (Ubuntu 22.04 & Debian 11.5 with the same results), and I'm having issues with the installer failing at EFI install step: VM Info: ``` root@pve02:~# cat /etc/pve/qemu-server/101.conf ...
上面选中行就是设置AddressOfEntryPoint的部分,其中text_start你可以认为是compressed部分的起始地址,而efi_pe_entry就是我们最终要找的 efi stub 入口函数。 选择行中将 text_start + efi_pe_entry (efi_pe_entry运行时的地址) 的结果,赋值到 pe_header + 0x28 指向的内存里,结合 pecoff 文档以及上面的header.S...
kernel. The arm64 EFI stub lives in arch/arm64/kernel/efi-entry.S and arch/arm64/kernel/efi-stub.c. and drivers/firmware/efi/libstub/arm64-stub.c. By using the EFI boot stub it's possible to boot a Linux kernel without the use of a conventional EFI boot loader, such as grub or...
