[Nouveau] BIG changes to kernel module

Hey all, I've just pushed a major rework/rewrite of the Nouveau kernel module to git[1]. Details of the whys and what-nots of the rework are in the various commit messages. At this point don't expect any exciting cool functionality, the work so far is merely a restructure to allow moving forward on a number of fronts in the future. I expect that for a while there will be a *lot* of stupid typos/thinkos that cause all sorts of breakage, so please test everything any anything you can and report *regressions* from the pre-rework code (vs 3.6-rc1 for example). I'll endeavour to hunt down and fix the regressions as quickly as possible, so please report any issues to this list and/or the freedesktop bugzilla. There's two areas that didn't get "properly" ported over, that is PM-related things and modesetting. I'll be handling the modesetting and clk/volt reworks starting from nowish (in between fixing regressions), and I suspect Martin will handle the rest of the PM bits (therm and fanctrl) since he knows the design he's going for there. One thing to note is that some kernel module options have changed now, the more important ones are: nouveau.vbios=<blah> -> nouveau.config=NvBIOS=<blah> nouveau.noaccel=<bool> -> nouveau.config=PGRAPH=<bool> Multiple options are specified like: nouveau.config=NvBIOS=ACPI,PGRAPH=1 The nouveau.noaccel option now controls acceleration enable/disable for the DRM's own GPU usage, and for the "abi16" (the new interfaces aren't even exposed to userspace yet) interfaces. The DRM debugging options (drm.debug=<bitfield>) now only effect the DRM specific parts of the nouveau module. To enable additional debugging etc for the core, incantations like the following are used now: for debug output nouveau.debug=debug or for even more verbose debug output nouveau.debug=trace or for trace output for everything, and register write logging from POST nouveau.debug=trace,DEVINIT=spam Each individual subdev/engine module has its own debug level that can override the master debug level. Now, I'm off to relax a bit (read: hide) before the storm of bug reports :) Cheers, Ben. [1] http://cgit.freedesktop.org/nouveau/linux-2.6
