Hello,

Was wondering if anyone ever tried to enable dcache write through on
the TS provided 2.4.26 kernel together with TS provided adeos patches.

This combination works fine when CONFIG_CPU_DCACHE_WRITETHROUGH is not
defined but when dcache write through is enabled, init and user
started processes die ramdonely with segmentation violations on the
console.

I am enableing CONFIG_CPU_DCACHE_WRITETHROUGH per Michael Neuhauser's
suggestion in saw on a web page (he did most of the adeos port to arm)
to improve the real time latency. The improvement is very big if only
I can solve these segmentation violations.

Thank You

Patrick Robin
