Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead of PCI to which Nouveau is tightly dependent. This patch allows Nouveau to handle platform devices by: - abstracting PCI-dependent functions that were typically used for resource querying and page mapping, - introducing a nv_device_is_pci() function that allows to make PCI-dependent code conditional, - providing a

MSIs were only problematic on some old, broken chipsets. But now that we already see systems where PCI legacy interrupts are somewhat flaky, it's really time to move to MSIs.

This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run. A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations. Lucas Stach (6): drm/ttm: recognize ARM arch in

The T124 generation of Tegra GPUs uses the Kepler architecture and can thus be driven by Nouveau. However, they are declared as platform devices using the Device Tree, and Nouveau has a very strong dependency on PCI. This patch makes Nouveau core able to handle platform devices as well as PCI devices. Commonly-used PCI functions include resource range query and page mapping. These functions are

Hello everyone, GK20A is the Kepler-based GPU used in the upcoming Tegra K1 chips. The following patches perform architectural changes to Nouveau that are necessary to support non-PCI GPUs and add initial support for GK20A. Although the support is still very basic and more user-space changes will be needed to make the full graphics stack run on top of it, we were able to successfully open
