## Debugging the BPF Virtual Machine eBPF Summit ## Why? ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load - I couldn’t find good resources on this, so so, here I am ● I break lots of eBPF programs - The BPF Virtual machine is not easy to understand ## The approach ## The BPF subsystem lives in the kernel ![Image](/uploads/documents/7/1/6/1/7161fc3 buildroot make menuconfig make -j16 Remember to: - Select ext4 as filesystem image - Enable networking - Enable the SSH daemon ## Start the test VM cd /source/linux qemu-system-x86_64 -kernel bu

Cppcon 2023 | Rud Merriam | A Journey into Non-Virtual Polymorphism ## Background ## • Experience with many languages – FORTRAN IV (1968!), PL/M, assembly, C, Turbo Pascal, Forth • Taught dispatch Cppcon 2023 | Rud Merriam | A Journey into Non-Virtual Polymorphism ## Polymorphic Variables • Base class pointer to derived class – Virtual functions are not bad! • Standard Template Library

## +23 ## Optimizing Away Virtual Functions May Be Pointless ## SHACHAR SHEMESH Slide #2 - who am I?  ## DO NOT ENTER One reviewer's notes: There are interesting technical details and surprising conclusions that virtual functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep slowdown - gcc Intel  Virtual vs. Concrete Run Times - gcc Intel ![Image](/uploads/documents/1/0/9/2/1092c89fc888067fdbc59ca7369237f9/p14_1
