2014-03-26drm/nouveau/bios: add more checks to PRAMIN image fetchingBen Skeggs1-1/+11
Prevents an attempt to access VRAM on an un-posted board, which, on a particular system with a GRID K1 installed, causes a MCE and chokes the entire system. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-03-26support for platform devicesAlexandre Courbot35-127/+305
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.

2014-03-26drm/nouveau: use nv_debug for NV_DEBUG, make DRM a separate subflagIlia Mirkin2-4/+3
It's really confusing for NV_DEBUG's printing to be controlled via drm.debug while everything else is controlled via nouveau.debug. These messages can be turned on with nouveau.debug=DRM=debug. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-03-26drm/nouveau: make hdmi device finding failure prints debug levelIlia Mirkin1-6/+5
The hdmi device is required for runtime pm. However it is not available on many esp older devices, which were all seeing these error messages. Take this opportunity to also convert to nv_debug instead of the DRM_* messages, like the rest of nouveau does.

2014-03-26drm/nouveau: handle -EACCES runtime PM return codeAlexandre Courbot3-4/+4
pm_runtime_get*() may return -EACCES to indicate a device does not have runtime PM enabled. This is currently the case with platform devices on Nouveau, and is not an error in that context. Handle this case without failure. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
