[LinuxBIOS] Initiate LDTSTOP (without RESET)

[Dan Johnson]

I have been reading over the mailing list and reading over the LinuxBIOS
code trying to get a feel for things but I am in need of some wisdom. 

 

It seems LDTSTOP is not used by the LinuxBIOS for the most part and I am
curious why. What I have gathered so far is that it is system specific
(Southbridge?) to trigger. I found some mailing list mentions of old
code from years ago that is no longer in the current tree.

 

I am searching for a way to disable and re-enable HT links for various
reasons _without_ performing a reset (for example changing link
speed/width or enabling/disabling devices at runtime). It seems that
LinuxBIOS has chosen to not use LDTSTOP and just use resets instead. Is
this a workaround due to the difficulty of implementing LDTSTOP?

 

I am using a Tyan K8SRE (S2891) motherboard. The board has an Nvidia
nForce 4 Pro (CK804).

 

Regards,

 

Dan Johnson
