I still don't understand what you mean. They are just the code that existed before, so what is silly in moving them since they depend upon bypassing the common i915_write/read code? > Also if > you extracted those as a separate patch to the gt funcs, you could have > had just a simple file move + rename.

Looks like you made the distinction pretty clear in that paragraph between gt and pm. The name change is mostly a whim because we no longer refer to this as being the GT. > Final bikeshed, I would like to see the reset code in a separate file as > well (included in this could be any GEM functions we have for reset > only, and display as well). No. Look at the reset code, it is far too incestrous with the gt/uncore mechanics to be anywhere else. And it didn't seem right to separate it up. -Chris -- Chris Wilson, Intel Open Source Technology Centre
