Pravidelná středeční sonda do světa software. Dnes se podíváme na správce proxy serverů, necháme si vykreslit průběhy (waveforms) z CSV a nakonec budeme testovat protokoly.

A patch was sent out on Sunday for adding new Linux kernel configuration options for tuning the kernel build to different x86_64 micro-architecture feature levels. The intent is on generating kernel builds that are faster for use on modern Intel and AMD systems. However, this patch is likely to not be accepted in the mainline kernel and has already been criticized upstream Linux kernel developers...

Last week the initial AMD Zen 5 "znver5" enablement for LLVM/Clang was posted by an AMD compiler engineer. That code has since undergone review and merged for LLVM 20 Git and yesterday then back-ported for LLVM 19...

Red Hat engineer Paolo Bonzini submitted the initial batch of KVM changes targeting the Linux 6.12 kernel. This is just the first batch and notably lacking all of the KVM x86 Intel/AMD changes for the cycle. But in the non-x86 space there is a fair amount of activity for this next kernel version for those making use of KVM as part of the open-source virtualization stack...

Zaměříme se na specifické instrukce, které byly na mikroprocesorech Intel 8086/8088 podporovány. Bude se v první řadě jednat o instrukce pro BCD aritmetiku a o „řetězcové instrukce“, které jsou pro platformu 8086 typické.
