Details
do_read_write is an open source RAM Benchmark by AVM which performs a Read / Write test (Load-Multiple).
Initially located at /proc/avm it was moved to /proc/avm/benchmark later. See the Path in the Model-Matrix.
This test performs an alternating mix of read and write memory accesses.
do_read_write is part of the MemBench suite. For an overview of all tests see help (procfs) and the Benchmark article.
Excerpt from the test results (german):
Immer schoen im Wechsel 1x Lesen und 1x Schreiben.
Excerpt from the source code avm_membench.c (german):
/*------------------------------------------------------------------------------------------*\ * Mixture Read/Write * * -1x 4-Byte Lesen + 1x 4-Byte Schreiben * -> 2 Zugriffe pro Schleifendurchlauf \*------------------------------------------------------------------------------------------*/

Model-Matrix
Daily updated index of the presence, path and size of this object for each model. Last update: 2024-11-21 05:21 GMT.
Showing all models using this object. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2
The data in this article is incomplete since it was manually collected using the Supportdata2 project.
Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.
It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
