Subject: [RFC PATCH 2/2] mips: bpf: enable 32-bit eBPF JIT
Date: Wed, 21 Jul 2021 01:10:36 +0200 [thread overview]
Message-ID: <20210720231036.3740924-3-johan.almbladh@anyfinetworks.com> (raw)
In-Reply-To: <20210720231036.3740924-1-johan.almbladh@anyfinetworks.com>
This patch enables the new 32-bit eBPF JIT for MIPS. It also disables
the old cBPF JIT to so cBPF programs are converted to use the new JIT.
