From: Vitaly Chikunov <vt@altlinux.org> To: devel-kernel@lists.altlinux.org Subject: [d-kernel] [PATCH] config: Disable DEBUG_INFO_BTF on aarch64 Date: Sat, 29 Oct 2022 00:35:15 +0300 Message-ID: <20221028213515.1844006-1-vt@altlinux.org> (raw) We have the same kernel for enterprise systems (like TaiShan) and toy computers (like Raspberry Pi). Raspberry Pi cannot boot newer kernels with U-Boot anymore[1] due to vmlinuz (that is uncompressed Image[2]) size approaching 40MB, (which is limited by fdt_addr_r=0x02600000 parameter specified in our U-Boot package). Obvious target to reduce size is removing .BTF section. As a downside this will reduce eBPF & tracing abilities on these platforms.
