From 31ce5e0c49821d92fb30cce2f3055ef33613b287 Mon Sep 17 00:00:00 2001 From: Jin Dongming Date: Fri, 10 Dec 2010 17:21:02 +0900 Subject: Add "broadcast" option for mce command When the following test case is injected with mce command, maybe user could not get the expected result. DATA command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Expected Result panic type: "Fatal Machine check" That is because each mce command can only inject the given cpu and could not inject mce interrupt to other cpus. So user will get the following result: panic type: "Fatal machine check on current CPU" "broadcast" option is used for injecting dummy data into other cpus. Injecting mce with this option the expected result could be gotten. Usage: Broadcast[on] command broadcast cpu bank status mcg_status addr misc (qemu) mce -b 1 1 0xbd00000000000000 0x05 0x1234 0x8c Broadcast[off] command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Signed-off-by: Jin Dongming Signed-off-by: Marcelo Tosatti --- hmp-commands.hx | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'hmp-commands.hx') diff --git a/hmp-commands.hx b/hmp-commands.hx index 1cea572..d65a41f 100644 --- a/hmp-commands.hx +++ b/hmp-commands.hx @@ -1116,9 +1116,9 @@ ETEXI { .name = "mce", - .args_type = "cpu_index:i,bank:i,status:l,mcg_status:l,addr:l,misc:l", - .params = "cpu bank status mcgstatus addr misc", - .help = "inject a MCE on the given CPU", + .args_type = "broadcast:-b,cpu_index:i,bank:i,status:l,mcg_status:l,addr:l,misc:l", + .params = "[-b] cpu bank status mcgstatus addr misc", + .help = "inject a MCE on the given CPU [and broadcast to other CPUs with -b option]", .mhandler.cmd = do_inject_mce, }, -- cgit v1.1
