From ec5e8461c194346c4341e3e8bb35bc06ad707d47 Mon Sep 17 00:00:00 2001 From: Chen Minqiang Date: Thu, 11 Jul 2019 22:34:03 +0800 Subject: x86: make crashdump works 1. KERNEL_CRASH_DUMP should depends on KERNEL_PROC_KCORE (kexec use it) 2. select crashkernel mem size by totalmem mem <= 256M disable crashkernel by default mem >= 4G use 256M for crashkernel mem >= 8G use 512M for crashkernel default use 128M 3. set BOOT_IMAGE in kdump.init 4. resolve a "Unhandled rela relocation: R_X86_64_PLT32" error Tested on x86_64 Signed-off-by: Chen Minqiang --- ...or-Unhandled-rela-relocation-R_X86_64_PLT32-error.patch | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 package/boot/kexec-tools/patches/100-kexec-tools-fix-for-Unhandled-rela-relocation-R_X86_64_PLT32-error.patch (limited to 'package/boot/kexec-tools/patches') diff --git a/package/boot/kexec-tools/patches/100-kexec-tools-fix-for-Unhandled-rela-relocation-R_X86_64_PLT32-error.patch b/package/boot/kexec-tools/patches/100-kexec-tools-fix-for-Unhandled-rela-relocation-R_X86_64_PLT32-error.patch new file mode 100644 index 0000000000..dfad21992b --- /dev/null +++ b/package/boot/kexec-tools/patches/100-kexec-tools-fix-for-Unhandled-rela-relocation-R_X86_64_PLT32-error.patch @@ -0,0 +1,14 @@ +diff --git a/kexec/arch/x86_64/kexec-elf-rel-x86_64.c b/kexec/arch/x86_64/kexec-elf-rel-x86_64.c +index 7fdde73..af33689 100644 +--- a/kexec/arch/x86_64/kexec-elf-rel-x86_64.c ++++ b/kexec/arch/x86_64/kexec-elf-rel-x86_64.c +@@ -78,7 +78,8 @@ void machine_apply_elf_rel(struct mem_ehdr *UNUSED(ehdr), + if ((int64_t)value != *(int32_t *)location) + goto overflow; + break; +- case R_X86_64_PC32: ++ case R_X86_64_PC32: ++ case R_X86_64_PLT32: + *(uint32_t *)location = value - address; + break; + default: -- cgit v1.2.3
