Dear RT Folks, This patch enables the netconsole on PREEMPT_RT_FULL, netconsole was disabled on commit: cb7cb77 kconfig-disable-a-few-options-rt.patch I tested the netconsole on three machines: - Intel Core i5 (4 cpus) - Local network - Intel Xeon (32 cpus) - Remote network - KVM VM (on a Core i7) - Virtual network On these machines I build the kernel 3.10.34-rt34 + netconsole built as module. In order to execute some printks, I run a small benchmark that runs as a module. To analyse the output I captured the netconsole messages using Wireshark. On all cases, the tests passed without any error: - No error messages from the kernel - No missed messages - No out of order messages I ran +1 hour tests on each machine. The test using the Xeon machine ran by around 10 hours. On this test I received 317149 netconsole's messages. I also read the code and ran some traces (using the ftrace's function_graph). In the traces that I read, the netconsole code never broke the rt lock assumptions.
