linux-toradex.git/arch/riscv/tools, branch master Linux kernel for Apalis and Colibri modules riscv: Stop considering R_RISCV_NONE as bad relocations 2025-07-16T15:13:55+00:00 Alexandre Ghiti alexghiti@rivosinc.com 2025-07-10T08:34:31+00:00 82d369b48a6bd70947f9016cb358e278a737e919 Even though those relocations should not be present in the final vmlinux, there are a lot of them. And since those relocations are considered "bad", they flood the compilation output which may hide some legitimate bad relocations.

riscv: Check relocations at compile time 2023-04-19T14:46:32+00:00 Alexandre Ghiti alex@ghiti.fr 2023-03-29T04:53:28+00:00 c2dea0bc53397166a77811d9b66928643a83d6f3 Relocating kernel at runtime is done very early in the boot process, so it is not convenient to check for relocations there and react in case a relocation was not expected. There exists a script in scripts/ that extracts the relocations from vmlinux that is then used at postlink to check the relocations.
