2015-01-22drm/nouveau: dont switch vt on suspendMaarten Lankhorst
Restore the nv50 cursor bo on resume, and load the lut in nv50_display_display_init so it gets set on resume too. Tested on a fermi and a curie. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@ubuntu.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/dispnv04: Remove some unused functionsRickard Strandqvist
Removes some functions that are not used anywhere: nv04_display_late_takedown() nv04_display_early_init() This was partially found by using a static code analysis program called cppcheck.

2015-01-22drm/nouveau/clk: allow users to enable auto mode when loading driverVince Hsu
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 Hsu
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 Hsu
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 Hsu
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/nouveau/mc: add missing bracesVince Hsu

2015-01-22drm/nv50-/kms: reject attempts at flipping to incompatible framebufferBen Skeggs
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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/kms: default to panel scaling, except for fixed panels prior to nv50Ben Skeggs
On NV50 and up, we'll allow fixed panels to use EDID-provided modes without the GPU scaler, and force scaling (even for NONE) otherwise. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-01-22drm/nv50-/kms: allow disabling of gpu scaling on fixed panelsBen Skeggs
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>

2015-01-22drm/nouveau: sgdma: add comment around suspiscious error handlerAlexandre Courbot
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.

2015-01-22drm/nouveau/core: prepare printk for NULL engine pointer on device object treeBen Skeggs
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). Later patches will append object and class identifiers to messages, which will help clarify where it's coming from. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-01-22drm/nouveau/core: drop the pointer value in debug printk outputBen Skeggs
Makes the output slightly less useful, in that objects with the same class handle can't be distinguished from each other now. Upcoming commits will name objects with user-readable strings to fix this problem. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-01-22drm/gf100-/bar: don't fill in bar->alloc until after all vm setup doneBen Skeggs
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.

2015-01-21drm/i2c: tda998x: set the CEC I2C address based on the slave I2C addressAndrew Jackson
The I2C address for the TDA9989 and TDA19989 is fixed at 0x34 but the two LSBs of the TDA19988's address are set by two configuration pins on the chip. Irrespective of the chip, the associated CEC peripheral's I2C address is based upon the main I2C address. This patch avoids any special handling required to support systems that contain multiple TDA19988 devices on the same I2C bus.

2015-01-21drm: Make drm_read() more robust against multithreaded racesChris Wilson
The current implementation of drm_read() faces a number of issues: 1. Upon an error, it consumes the event which may lead to the client blocking. 2. Upon an error, it forgets about events already copied 3. If it fails to copy a single event with O_NONBLOCK it falls into a infinite loop of reporting EAGAIN. 3. There is a race between multiple waiters and blocking reads of the events list. Here, we inline drm_dequeue_event() into drm_read() so that we can take the spinlock around the list walking and event copying, and importantly reorder the error handling to avoid the issues above.

2015-01-21drm: add Atmel HLCDC Display Controller supportBoris Brezillon
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.
