From: Borislav Petkov <firstname.lastname@example.org> Hi, here's another round of the RAS daemon patchset. This time I'd like to get some ACKs/NACKs on the perf bits and whether this is agreeable to do. To some of the patches: * 0001-perf-Start-the-massive-restructuring.patch: This renames perf_event.c into events/core.c, as talked about earlier. This is only a first step though, the rest should come from perf people I guess... * 0002-perf-Add-persistent-event-facilities.patch ... and this one puts the persistent bits in persistent.c * 0004-perf-Add-Makefile.lib.patch * 0005-perf-Export-trace-event-utils.patch I'm adding a toplevel tools/Makefile here which we could use for the other tools in there since we keep growing even more tools with each kernel release. * 0007-perf-Export-debugfs-utilities.patch This one is needed only temporary, as we're moving the perf events to /sysfs. After that work is done, the persistent fd will be read from there. For more details, check the individual patches. Btw, the patches are ontop of tip/master from ~two weeks ago, i.e.: cf1f6cd677a9ce8c80e5de61724a25074ad9a8cf. In order to run this patchset, you need only this hunk: --- diff --git a/drivers/edac/mce_amd.c b/drivers/edac/mce_amd.c index c018109..7bffbc6 100644 --- a/drivers/edac/mce_amd.c +++ b/drivers/edac/mce_amd.c @@ -1,5 +1,6 @@ #include <linux/module.h> #include <linux/slab.h> +#include <trace/events/mce.h> #include "mce_amd.h" @@ -598,6 +599,8 @@ int amd_decode_mce(struct notifier_block *nb, unsigned long val, void *data) amd_decode_err_code(m->status & 0xffff); + trace_mce_record(m); + return NOTIFY_STOP; } EXPORT_SYMBOL_GPL(amd_decode_mce); --- so that you can inject some MCEs like so: $ cd tools/ $ make -j ras $ ./ras/rasd $ modprobe mce_amd_inj (built by CONFIG_EDAC_MCE_INJ) $ echo 0x9c00410000010016 > /sys/devices/system/edac/mce/status $ echo 0 > /sys/devices/system/edac/mce/bank And after 30 sec the latest, /var/log/ras.log will contain: Got MCE, cpu: 0, status: 0x9c00410000010016, addr: 0x0000000000000000 This is still undecoded yet but I'm working on it. Anyway, please take a look and send me all comments you'd have.
