This series does some refactoring in the GK20A's volt and clk drivers (fixing a few things while we are at it) to let GM20B benefit from the GK20A's logic with which it is compatible. GM20B is capable of more sophisticated (and power-efficient) reclocking which will follow later. Even after this more fancy reclocking is merged, the pre...

Commit "ltc/gf100-: fix cbc issues on certain boards" moved the setting of the large page size bit from bar/nvc0 to fb/nvc0. GK20A uses its own FB device and the change was thus not applied to it - fix this.

...k more stable and allowing it to run safely at lower voltage. All GM20B additions are done in the last patch, which consequently ends up being considerably big ; fortunately, it only consists of code additions thanks to the big refactoring work done by the first 14 patches. This refactoring makes GK20A's clock code much simpler to read and understand, and flexible enough to be reused by GM20B's when relevant. Note that the sliding and MNP programming had to be re-implemented due to the differences introduced by DFS - trying to factor them out with more abstractions resulted in rather ugly...

Commit bbb163e18960 ("drm/nouveau/bar: implement bar1 teardown") introduced add a teardown helper function for BAR1. During initialisation of the Nouveau, initially all the teardown helpers are called once, before calling their init counterparts. For gk20a, after the BAR1 teardown function is called, the device is hanging during the initialisation of the FB sub-device. At this point it is unclear why this is happening and this is still under investigation. However, this change is preventing Tegra124 devices from booting when Nouveau is enabled. To al...

Does GK20A itself have any kind of thermal protection capabilities? Upstream SOCTHERM support is not yet available (though I have a driver in my tree), so we are thinking of disabling CPU DVFS on boards that don't have always-on active cooling for now. Same might be necessary for GPU as well. On 10/0...
