Subject: [PATCH 0/5] Minimize the need to move the kernel in the EFI stub
Date: Sun, 1 Mar 2020 18:05:32 -0500 [thread overview]
Message-ID: <20200301230537.2247550-1-nivedita@alum.mit.edu> (raw)
This series adds the ability to use the entire PE image space for
decompression, provides the preferred address to the PE loader via the
header, and finally restricts efi_relocate_kernel to cases where we
really need it rather than whenever we were loaded at something other
than preferred address.
Based on tip:efi/core + the cleanup series just posted [1]
[1] https://lore.kernel.org/linux-efi/20200301230436.2246909-1-nivedita@alum.mit.edu/
Arvind Sankar (5):
x86/boot/compressed/32: Save the output address instead of
recalculating it
efi/x86: Decompress at start of PE image load address
efi/x86: Add kernel preferred address to PE header
efi/x86: Remove extra headroom for setup block
efi/x86: Don't relocate the kernel unless necessary
