Subject: [PATCHv2 0/3] btf_encoder: Detect kernel modules
Date: Thu, 3 Dec 2020 23:06:22 +0100 [thread overview]
Message-ID: <20201203220625.3704363-1-jolsa@kernel.org> (raw)
hi,
adding support to detect kernel module and use its
mcount_loc section data as function filter.
v2 changes:
- initialize return arguments in get_vmlinux_addrs [Andrii]
- use elf_getscn in elf_section_by_idx [Andrii]
- use address size from ELF's class for both kmod and vmlinux
thanks,
jirka
