Subject: [Buildroot] [RFC PATCH 2/4] Add BPF Compiler Collection (BCC) Package
Date: Tue, 29 Sep 2020 11:26:16 +0100 [thread overview]
Message-ID: <20200929102618.28571-3-qais.yousef@arm.com> (raw)
In-Reply-To: <20200929102618.28571-1-qais.yousef@arm.com>
BCC is a toolkit for creating efficient kernel tracing and manipulation
programs, and includes several useful tools and examples.
Only tested to work on x86_64 and aarch64.
I had issues getting i386 and aarch32 to work. More archs support can be
added later hopefully after this initial support.
