commit 424089a0fc82ee9db8659b8c1099bbbde8999473 Author: Warner Losh <[email protected]> AuthorDate: 2025-12-28 05:27:03 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2025-12-28 05:27:03 +0000 loader: Fix powerpc64le by working around slof bug in qemu/slof Fix powerpc 64 little endian booting by adding some padding. Due to https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L114 https://gitlab.com/slof/slof/-/blob/master/lib/libelf/elf32.c?ref_type=heads#L150 using <= instead of <, slof used to loop over the phdrs. It overruns by 1 and so on little endian it swizzles the first 32 bytes of .text. Work around this by adding 32 bytes of padding after the headers. We should fix this in slof, but it's in the just released QEMU 10.2, so we have to pad things here for now. Now powerpc64le + qemu works.
