Details

mips-options shows hex encoded MIPS capabilities flags for this processor.
So far it was only found on VR9, pretty hackish unaligned with the remaining properties of cpuinfo,
starting an empty line separated own block per processor.

This lists the flags encoded as explained starting from line 333 of arch/mips/include/asm/cpu.h (blame, raw).

mips-options: 0x006d638b    # line 358+   CPU Option encodings
 icache.flags 0x00000000    # not in torvalds source?
 dcache.flags 0x00000004    # not in torvalds source?
    isa_level 0x00000063    # line 335+   ISA Level encodings
         ases 00000031      # line 426+   CPU ASE encodings

Model-Matrix

Daily updated index of the presence, path and size of this property for each model. Last update: 2024-03-28 05:21 GMT.
Showing all models using this property. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
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!
