BPF Compiler Collection (BCC)
|
|
|
|
BCC is a toolkit for creating efficient kernel tracing and
|
|
manipulation programs, and includes several useful tools and
|
|
examples. It makes use of extended BPF (Berkeley Packet
|
|
Filters), formally known as eBPF, a new feature that was
|
|
first added to Linux 3.15. Much of what BCC uses requires
|
|
Linux 4.1 and above.
|
|
|
|
Note: Before using bcc, you need either need to :
|
|
- For kernel_ver = [4.1, 5.2) : Copy kernel source code
|
|
to target folder /lib/module/<kernel_ver>/build.
|
|
- Or kernel_ver >= 5.2 : Compile kernel with CONFIG_IKHEADERS
|
|
and use generated headers under /sys/kernel/kheaders.tar.xz
|
|
to populate /lib/module/<kernel_ver>/build.
|
|
|
|
That's because the clang frontend build eBPF code at runtime.
