A1 X1000: no CPU cache under linux?
Posted: Tue Jun 09, 2020 5:55 pm
Hi,
if I listed CPU params under AmigaOS it reports CPU caches as expected:
https://img34.rajce.idnes.cz/d3403/16/1 ... info_2.jpg
But under linux is reported only L1 cache, and L2 cache is allways 0. getconf output is L1=L2=0
https://img34.rajce.idnes.cz/d3403/16/1 ... -linux.jpg
See also lstopo - shows two single-core sockets and no L2 cache, and not one dual-core.
Do anybody know origin of these number ( hwtree or something) ?
Do have this impact on speed with linux, or is it only "cosmetics" info?
Is the same problem on other platforms? I have to look on Pegasos and powermac.
