Subject: [PATCH v2 0/5] MIPS: relocate: Add automatic relocation to CONFIG_RELOCATABLE
Date: Mon, 12 Apr 2021 20:28:09 +0800 [thread overview]
Message-ID: <1618230494-6207-1-git-send-email-hejinyang@loongson.cn> (raw)
1, To get the address the kernel is linked to, use PC-region(static) +
offset(dynamic) way. See detail at [PATCH v2 3/5]
2, To deal with smp cpu in kernel entry, e.g. cavium-octeon platform,
move smp cpu handle later than jump to the address kernel linked to.
See detail at [PATCH v2 4/5]
Jinyang He (5):
MIPS: relocate: Only compile relocs when CONFIG_RELOCATABLE is enabled
MIPS: relocate: Use CONFIG_RANDOMIZE_BASE to enable kaslr
MIPS: Jump to kernel linked address by PC relative way
MIPS: cavium-octeon: Execute the smp handle after jumping to kernel
linked address
MIPS: relocate: Add support to auto relocate kernel
