Details

do_writeburst is an open source RAM Benchmark by AVM which performs a Store-Multiple Write test.

This test is only available on ARM CPUs and uses Burst-Write / Store-Multiple.
See the explanation of the ARM STMIA (Store Multiple, Increment After) assembler command.

do_writeburst is part of the MemBench suite. For an overview of all tests see help (procfs) and the Benchmark article.

Excerpts from the test results (german):

6490 ARM:
Burst-Schreiben unter Nutzung von store multiple.

Examples

7530 fw 7.29 example:

root@fritz1:/var/mod/root# cat /proc/avm/benchmark/do_writeburst

cat: read error: Cannot allocate memory

6490 fw 7.29 example - ARM side:

root@fritz2:/var/mod/root# rpc cat /proc/avm/benchmark/do_writeburst

Daily updated index of the presence, path and size of this object for each model. Last update: 2024-12-23 05:10 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!
