* drm/nouveau/sw: rename from software (no binary change)Ben Skeggs2015-01-2232-334/+334
| | | | | | | | | | | | | | | | | | Shorter device name, make consistent with our engine enums. 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: remove symlinks, move core/ to nvkm/ (no code changes)Ben Skeggs2015-01-22609-454/+510
| | | | | | | | | | | | The symlinks were annoying some people, and they're not used anywhere else in the kernel tree. The include directory structure has been changed so that symlinks aren't needed anymore. NVKM has been moved from core/ to nvkm/ to make it more obvious as to what the directory is for, and as some minor prep for when NVKM gets split out into its own module (virt) at a later date.

* drm/nouveau: merge nouveau_platform.ko into nouveau.koAlexandre Courbot2015-01-225-11/+14
| | | | | | | | | | | Having the two modules separated causes various unneeded complications, including having to export symbols accessed between the modules. Make things simpler by compiling platform device support into nouveau.ko. Platform device support remains optional and is only compiled on Tegra.

* drm/nouveau/clk: allow users to enable auto mode when loading driverVince Hsu2015-01-221-0/+3

* drm/nouveau/pwr: add support for GK20AVince Hsu2015-01-224-0/+235
| | | | | | | | | | | | | This patch adds PWR support for GK20A. But instead of adding the PWR features like firmware loading and communication with PMU firmware, we add the DVFS (Dynamic Voltage and Frequency Scaling), which is one of the PMU firmware's jobs on dGPUs, in this patch. This refers to the idle signals provided by the NVIDIA hardware and tries to adjust the performance level based on the calculated target. The reclocking policy can be fine-tuned later when we have more real use cases. Signed-off-by: Vince Hsu <vinceh@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/pwr: make nouveau_pwr_pgob() non-staticVince Hsu2015-01-222-1/+2
| | | | | | | | | The platform device does not use the common nouveau_pwr_init() to initialize the PWR, but it does need the .pgob() be assigned to avoid NULL pointer dereference in graph/nve4.c. Signed-off-by: Vince Hsu <vinceh@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/clk: allow non-blocking for nouveau_clock_astate()Vince Hsu2015-01-222-3/+3
| | | | | | | | | | | There might be some callers of nouveau_clock_astate(), and they are from inetrrupt context. So we must ensure that this function can be atomic in that condition. This patch adds one parameter which is subsequently passed to nouveau_pstate_calc(). Therefore we can choose whether we want to wait for the pstate work's completion or not.

* drm/nv50-/kms: reject attempts at flipping to incompatible framebufferBen Skeggs2015-01-221-0/+4
| | | | | | | | | | | | | Looks like a userspace bug can trigger this somehow during a mode switch, causing: EVO complaint -> semaphores get out of sync -> entire display stalled. We likely want to be even stricter than this (or at least deal better if EVO rejects our request), but I'll save that for the drm_plane/atomic conversion and just fix the bug that I already know can be triggered.

| | | | | | | | | | The hilarious part is that, under X, this won't work anyway because the server decides to construct its own modes for some reason. Tested with modetest, which isn't quite as insane. I'd hope that wayland is more sensible. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: sgdma: add comment around suspiscious error handlerAlexandre Courbot2015-01-221-0/+5
| | | | | | | | | | | | Common programming sense dictates that resources allocated by a function are freed by this function should it fails, but this is not the case for the allocated structure of nouveau_sgdma_create_ttm(). It seems that n00b contributors attempt to fix this one like bugs flying towards a bug zapper, so add a comment to hopefully prevent this from happening anymore.

| | | | | | | | | | | | The [ SUBDEV] specified in log output will be a bit different for children of a subdev now. Previously this reports whatever subdev is specified by object.engine, now it reports the subdev that owns the object (so, up object.parent somewhere).

The bar->alloc part of the condition isn't currently necessary (it used to be, another change made bar always NULL where it matters), so we got lucky. That won't be the case for much longer.
