Hello,
This patch series refactors the x86_64 UEFI set up process, fixes the
`run-tests.sh` script to run under UEFI, and improves the boot speed
under UEFI. The patches are organized as four parts.
The first part (patches 1-3) refactors the x86_64 UEFI set up process.
The previous UEFI setup calls arch-specific setup functions twice and
generates arch-specific data structure. As Andrew suggested [1], we
refactor this process to make only one call to the arch-specific
function and generate arch-neutral data structures. This simplifies the
set up process and makes it easier to develop UEFI support for other
architectures.
The second part (patch 4) converts several x86 test cases to
position-independent code (PIC) to run under UEFI. This patch is ported
from the initial UEFI support patchset [2] with fixes to the 32-bit
compilation.
The third part (patches 5-8) fixes the UEFI runner scripts. Patch 5
sets UEFI OVMF image as read-only. Patch 6 fixes test cases' return
code under UEFI, enabling Patch 7-8 to fix the `run-tests.sh` script
under UEFI.
The fourth part (patches 9-10) improves the boot speed under UEFI.
Patch 9 renames the EFI executables to EFI/BOOT/BOOTX64.EFI. UEFI OVMF
recognizes this file by default and skips the 5-second user input
waiting. Patch 10 makes `run-tests.sh` work with this new EFI
executable filename.
This patchset is based on the `uefi` branch.
