From 440a5f6ee682a9ab17a3da00178733b39749bdcf Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Mon, 31 Jan 2022 13:54:08 +0000 Subject: oeqa/runtime/stap: improve systemtap test Split the test up into compile and execute phases, as the stap binary is known to be quite memory-hungry and this can result in the probe being unable to allocate enough memory for the buffers it needs. If the test fails, dump the dmesg as any useful messages will be there.
