Hi Paul, Leo's latest CI build of perfbook-eb.pdf failed as you can see at: https://gitlab.com/linux-kernel/perfbook/-/jobs/7668105673 This is because the new Figure 3.13, or cpu/SimpleWrite.svg, is optimized for -2c builds and too tall for -eb size. A quick fix would be to shrink the figure for -eb builds, but that would result in a small diagram hard to read. Also, the new figure is not yet mentioned in the text. Furthermore, the corresponding enum list talks about CPU 0 doing a store, whose cache line is transferred from CPU 7's cache, while the figure presents a cache line transfer between CPU 1 and CPU 6. My guess is you are planning to adjust either of the list or the figure. Tweaking the width of the figure can wait a while. I suppose. Thanks, Akira
