# 6b64128a	19-Nov-2024	Sebastian Andrzej Siewior <[email protected]>	selftests/bpf: Check for PREEMPTION instead of PREEMPT CONFIG_PREEMPT is a preemtion model the so called "Low-Latency Desktop". A different preemption model is PREEMPT_RT the so called "Real-Time". selftests/bpf: Check for PREEMPTION instead of PREEMPT CONFIG_PREEMPT is a preemtion model the so called "Low-Latency Desktop". A different preemption model is PREEMPT_RT the so called "Real-Time". Both implement preemption in kernel and set CONFIG_PREEMPTION. There is also the so called "LAZY PREEMPT" which the "Scheduler controlled preemption model". Here we have also preemption in the kernel the rules are slightly different. Therefore the testsuite should not check for CONFIG_PREEMPT (as one model) but for CONFIG_PREEMPTION to figure out if preemption in the kernel is possible.

# 0334b4d8	25-Oct-2022	Martin KaFai Lau <[email protected]>	selftests/bpf: Ensure no task storage failure for bpf_lsm.s prog due to deadlock detection This patch adds a test to check for deadlock failure in bpf_task_storage_{get,delete} when called by a slee selftests/bpf: Ensure no task storage failure for bpf_lsm.s prog due to deadlock detection This patch adds a test to check for deadlock failure in bpf_task_storage_{get,delete} when called by a sleepable bpf_lsm prog. It also checks if the prog_info.recursion_misses is non zero. The test starts with 32 threads and they are affinitized to one cpu. In my qemu setup, with CONFIG_PREEMPT=y, I can reproduce it within one second if it is run without the previous patches of this set. Here is the test error message before adding the no deadlock detection version of the bpf_task_storage_{get,delete}: test_nodeadlock:FAIL:bpf_task_storage_get busy unexpected bpf_task_storage_get busy: actual 2 != expected 0 test_nodeadlock:FAIL:bpf_task_storage_delete busy unexpected bpf_task_storage_delete busy: actual 2 != expected 0 Signed-off-by: Martin KaFai Lau <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alexei Starovoitov <[email protected]> show more ...
