* drm/nouveau/device: audit and version NVIF_CONTROL class and methodsBen Skeggs2014-08-101-56/+105
| | | | | | | | The full object interfaces are about to be exposed to userspace, so we need to check for any security-related issues and version the structs to make it easier to handle any changes we may need in the future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | The one place where it mattered has been replaced with a class check, which is more appropriate anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau/core: rework event interfaceBen Skeggs2014-08-102-3/+22
| | | | | | | | | | | | | | | This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/gk20a: reclocking supportAlexandre Courbot2014-08-101-0/+1
| | | | | | | | | Add support for reclocking on GK20A, using a statically-defined pstates table. The algorithms for calculating the coefficients and setting the clocks are directly taken from the ChromeOS kernel.

* drm/nouveau: map pages using DMA APIAlexandre Courbot2014-08-101-25/+0
| | | | | | | | | | The DMA API is the recommended way to map pages no matter what the underlying bus is. Use the DMA functions for page mapping and remove currently existing wrappers.

* drm/gk20a: add BAR instanceAlexandre Courbot2014-08-101-1/+1
| | | | | | | | GK20A's BAR is functionally identical to NVC0's, but do not support being ioremapped write-combined. Create a BAR instance for GK20A that reflect that state. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>

| | | | | | | As a side note.. It's a bit hard to figure out how to name this commit.. GK20A is NVEA, which is before NV108 (GK208).. Confusing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/gk104/pwr: implement PGOB disable methodBen Skeggs2014-08-101-2/+2
| | | | | | | | | | | | | | | | | As documented at: ftp://download.nvidia.com/open-gpu-doc/gk104-disable-graphics-power-gating/1/gk104-disable-graphics-power-gating.txt NVIDIA were not able document the steps necessary to detect whether this is required or not at this time. However, they did confirm that this procedure is safe to perform unconditionally on GK104/6. GK107 does not have the power gating feature, and it was recommended that we do not perform these steps there as the effects were not verified. The disable path is from observing the binary driver, and not documented in the link above. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* support for platform devicesAlexandre Courbot2014-03-261-5/+78
| | | | | | | | | | | | | | | | | | | | | 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.
