Subject: [PATCH] kdump test comments:
Date: Tue, 2 May 2017 17:47:17 +0800 [thread overview]
Message-ID: <20170502094718.188172-1-yanjiang.jin@windriver.com> (raw)
From: Yanjiang Jin <yanjiang.jin@windriver.com>
1. Execute a kdump test on a "Freescale LayerScape LS1021E, Version: 2.0 board";
2. I think may all "proc-v7-3level" CPUs need this patch, but I only validated it on LS1021, so still use
#ifdef CONFIG_SOC_LS1021A
to wrap this change;
3. Append "crashkernel=128M@2560M" in UBoot's command line;
4. Use uImage as kdump's first kernel and capture kernel, but ls1021A doesn't define LOADADDR now,
so add below code in "arch/arm/boot/Makefile" temporarily to build an uImage:
+ifeq ($(CONFIG_SOC_LS1021A), y)
+LOADADDR=0x80008000
+endif
+
