"A Retargetable C Compiler" by Hanson – this details the implementation of LCC, which is a production grade compiler. It's a serious resource. Might be a bit too much for a first compiler;

"Practical Compiler Construction" by Nils M Holms – haven't read this one, but his work seems OK, if a bit idiosyncratic;

"Modern Compiler Implementation in C" by Andrew Appel – a good resource, but the code might be non-idiomatic C and hard to follow since it's translated from the ML version of the book (I've only read the Java version, and the code is kind of bad).

There's also Wirth's "Compiler Construction", which introduces you to a no nonsense compiler for Oberon. It's not C, but you can change it quite easily.

Home - DPDK GitHub - DPDK/dpdk: Data Plane Development Kit

By leveraging DPDK libraries, developers can create optimized packet processing paths, manage timers for executing functions asynchronously, and utilize a wide range of drivers and libraries tailored for fast packet processing.

librte_eal – Environment Abstraction Layer: Provides the foundational API for DPDK, facilitating access to hardware resources such as memory, timers, and logs.

librte_mempool – Memory Pool Manager: Manages memory pools for efficient and speedy packet handling.

librte_ring – Ring Buffer Manager: Implements lock-free FIFO queues, enabling high-speed communication between various DPDK components.

librte_mbuf – Packet Buffer Management: Handles packet buffers, which are crucial for packet transmission and reception.

librte_ethdev – Ethernet Device API: Offers an API for configuring and querying Ethernet devices. It supports various operations, including sending and receiving packets.

librte_net – Network Helper Library: Provides helper APIs for dealing with network protocols.

librte_ip_frag – IP Fragmentation and Reassembly: Handles fragmentation and reassembly of IP packets, supporting both IPv4 and IPv6.

librte_kni – Kernel Network Interface: Facilitates communication between DPDK applications and the Linux kernel networking stack, primarily used for debugging or interfacing with existing Linux network services.

• bpftrace seems quite powerful, will be useful for sysmon activities

where would ebpf support go?

probably io.. but maybe also log, net.. syn?

Realistically we may need a dedicated lib/math..

obj doesn't cover all the bases.

SBCL provides the numeric tower via types, we really need a math tower..
