Hi Dale, Please note that SPDK is working in userspace rather than kernelspace. Therefore we don’t have any function for writing to dmesg log. However, because it’s userspace you can just use one of the spdk log function, e.g. SPDK_NOTICELOG(). It will write to stderr and system logger. You can also use just printf for debugging. -- Best Regards, Piotr Pelpliński From: SPDK [mailto:spdk-bounces@lists.01.org] On Behalf Of Dale Corlett Sent: Wednesday, December 14, 2016 07:02 To: Storage Performance Development Kit <spdk(a)lists.01.org&gt; Subject: [SPDK] SPDK printk? Hi, Is there a printk() equivelent for SPDK? I want to write debug messages to the system log (dmesg).
