Subject: [PATCH bpf-next 0/3] s390/bpf: Support load-acquire and store-release instructions
Date: Thu, 23 Jul 2026 16:03:48 +0200 [thread overview]
Message-ID: <20260723140648.583055-5-max@linux.ibm.com> (raw)
Support load-acquire (BPF_LOAD_ACQ) and store-release (BPF_STORE_REL)
instructions. Since s390 has strong memory model, implement
them as regular BPF_LDX/BPF_STX instructions.
Maxim Khmelevskii (3):
s390/bpf: Add emit_ldx and emit_stx functions
s390/bpf: Support load-acquire and store-release instructions
s390/bpf: Enable atomics tests for s390
