drm/nouveau/mc: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau: use MSI interrupts 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. v2 (Ben Skeggs): blacklist BR02 boards Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

support for platform devices 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 nouveau_drm_platform_probe() function that takes a GPU platform device to be probed. Core code as well as engine/subdev drivers are updated wherever possible to make use of these functions. Some older drivers are too dependent on PCI to be properly updated, but all newer code on which future chips may depend should at least be runnable with platform devices.
