Remove the function nouveau_bo_rd16() that is not used anywhere. This was partially found by using a static code analysis program called cppcheck. Signed-off-by:

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:

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:

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:

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. Signed-off-by:

Several braces were misplaced unintentionally. That caused the msi handling became part of the default case of the first switch statement. So add the missing ones. Signed-off-by:

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.

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: -

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: -

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. Signed-off-by:

nouveau_sgdma_be::dev is only set once during init and never used anywhere, so remove it. Signed-off-by:

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 authored
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: -

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.

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: -

- Infrastructure work in amdkfd to prepare for VI support. This work mainly includes separating modules into ASIC-specific functionality, adding new properties that are relevant for VI, making sure that shared code is reused, etc. - Improve mechanism of submitting packets to HIQ (the kernel queue that amdkfd uses to issue commands to the GPU). The driver used to verify that each CS was read by the GPU. However, this proved to be both unnecessary and erroneous. Therefore, we cancelled this verification. - Moved initialization of compute VMIDs into radeon driver - Various minor fixes * tag 'drm-amdkfd-next-2015-01-21' of git://people.freedesktop.org/~gabbayo/linux: (22 commits) drm/amdkfd: Fix description of sched_policy module parameter drm/amdkfd: Remove sync_with_hw() from amdkfd drm/amdkfd: Remove unused function busy_wait() drm/amdkfd: Replace cpu_relax() with schedule() in DQM drm/amdkfd: Fix for-loop when allocating HQD (non-HWS) drm/amdkfd: Add initial VI support for KQ drm/amdkfd: Encapsulate KQ functions in ops structure drm/amdkfd: Add initial VI support for DQM drm/amdkfd: Encapsulate DQM functions in ops structure drm/amdkfd: Don't BUG on freeing GART sub-allocation drm/amdkfd: Fix logic of destroy_queue_nocpsch() MAINTAINERS: Update amdkfd files drm/amdkfd: Change MQD manager to be H/W specific drm/amdkfd: Add asic property to kfd_device_info drm/amdkfd: Make KFD_MQD_TYPE enum types H/W agnostic drm/amdkfd: Add new VI-specific queue properties drm/radeon: Use new cik_structs.h file drm/amdkfd: Don't include header files from radeon drm/amd: Put cik structures in a common place drm/radeon: Don't use relative paths in #include ...

Pull superh tracing fix from Steven Rostedt: "It's been reported that function tracing does not work on the sh architecture because gcc 4.8 for superH does not support -m32, and the recordmcount.pl script adds "-m32" when re-compiling the object files with the mcount locations. I was not able to reproduce this problem, as it seems that -m32 works fine for my cross compiler gcc 4.6.3, but I have to assume that -m32 was deprecated somewhere between 4.6 and 4.8. As it still seems to compile fine without -m32, I have no reason not to add this patch, as having -m32 seems to cause trouble for others" * tag 'trace-sh-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: scripts/recordmcount.pl: There is no -m32 gcc option on Super-H anymore

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. The HLCDC block provides a single RGB output port, and only supports LCD panels connection to LCD panels for now. The atmel,panel property link the HLCDC RGB output with the LCD panel connected on this port (note that the HLCDC RGB connector implementation makes use of the DRM panel framework). Connection to other external devices (DRM bridges) might be added later by mean of a new atmel,xxx (atmel,bridge) property. Signed-off-by:

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. Signed-off-by:
