The CPU model and type has significant impact on certain bugs, such as contention issues caused by CPUs having split L3 caches, or stricter memory models that exhibit some barrier issues. It's complicated though because the info about the model depends on the arch. For example, x86 reports an SKU name while ARM rather reports the CPU core types, families and versions for each CPU core. There, the SoC will sometimes be reported in the device tree or DMI info instead. But we don't really care, it's essentially useful to know if the code is running on an armv8.0 such as A53, a 8.2 such as A55/A76/Neoverse etc. For MIPS the model appears to generally be there, and in addition the SoC is often present in the "system type" field before the first CPU, and the type of machine in the "machine" field, to replace the missing DMI and DT, so they are also collected. Note that only the first CPU is checked and reported, that's expected to be vastly sufficient, since we're just trying to spot known incompatibilities or issues. |

The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
