debug ahci controller

[Shaun]

any body knows how to debug ahci controller, is there any debugger avaliable for that?

i have trouble with my ahci controller dirver, based on the serial ata spec pubblished by intel, my driver work fine on my hp ich6 chipset and virtualbox, but it is weird on my asus laptop which uses intel ich9m chipset, the ahci reset command always timeout.

virtualbox can only show me the result of my driver works, but for figuring out what and where i need to fix my code through debugging it step by step, any one have some good sulotions or suggestions?

thanks.

Debugging support is something that should be present in your OS, not in the emulators you use. How else would you go about debugging when real hardware doesn't work?
