From 4b54214f39ff24a7e9b7231ae9c05d1c2c424280 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20T=C3=B6pel?= Date: Thu, 28 Oct 2021 18:10:54 +0200 Subject: [PATCH] riscv, bpf: Increase the maximum number of iterations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that BPF programs can be up to 1M instructions, it is not uncommon that a program requires more than the current 16 iterations to converge. Bump it to 32, which is enough for selftests/bpf, and test_bpf.ko.
