2015-01-22drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)Ben Skeggs257-46070/+0
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.

2015-01-22drm/nouveau/clk: allow users to enable auto mode when loading driverVince Hsu1-0/+3
This patch adds one option for the boot config strings "NvClkMode*", so that we can enable the "auto" mode when loading module. Signed-off-by: Vince Hsu <vinceh@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/pwr: add support for GK20AVince Hsu1-0/+232
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>
2015-01-22drm/nouveau/pwr: make nouveau_pwr_pgob() non-staticVince Hsu2-1/+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>
2015-01-22drm/nouveau/clk: allow non-blocking for nouveau_clock_astate()Vince Hsu1-2/+2
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.

2015-01-22drm/gf100-/bar: don't fill in bar->alloc until after all vm setup doneBen Skeggs1-2/+4
gpuobj has a condition of (bar && bar->alloc) around usage to avoid some nasty ordering issues (which, i've now been reminded to add a todo about fixing...) between bar and vm. 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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/core: rename subclass.base to subclass.superclassBen Skeggs1-2/+1
Makes things a bit more readable. This is specially important now as upcoming commits are going to be gradually removing the use of macros for down-casts, in favour of compile-time checking. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-12-02drm/nouveau/bios: translate ramcfg strap through M0203Ben Skeggs1-1/+12
A machine has been spotted where the ramcfg strap is "8", and the ramcfg xlat table goes 0-7,0-7, resulting in us selecting config 0 for memory items. On this particular system, config "8" is available and supposed to be used. It appears that starting from GT21x (where Mv2 appears), we're supposed to use the value in this table instead. One concern here is that not all the places we currently use ramcfg xlat are supposed to be treated the same now. The strap xlat table wasn't removed from the vbios either, presumably for some kind of good reason. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

We only support one kind of matching here (ramcfg strap), but it appears alternate methods are possible. I wrote a tool to scan our vbios repo for other types, but did not see any used. Hopefully this means there aren't any in the wild that will now break. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
