* gpu: vgpu: gp10b: Add map failure debuggingAlex Waterman2017-08-28
| | | | | | | | | | | | | | | The vGPU mapping code in gp10b gives very little debugging info when there's a failure. This change adds much more detail to the error printing so that thee failures can more easily be debugged without needing to run the virtual guest locally.

* gpu: nvgpu: cleanup allocator debuggingAlex Waterman2017-08-28
| | | | | | | | | | | | | | | | | Remove debugging features that did not really get used and make the debugging code use the nvgpu_log() functionality. This ties the allocator debugging into the larger nvgpu debug framework. Also modify many of the places CONFIG_DEBUG_FS was used to conditionally compile allocator debug code to use __KERNEL__ instead. This is because that debug code can still be called even when debugfs is not present in Linux.

* nvgpu: Fix include paths for in-tree buildsStephen Warren2017-08-25
| | | | | | | | | | | | | | | | | | | | When compiling the kernel with an O= option (which stores built files outside the source tree) the kernel adds various extra source paths to the system include path. However, this doesn't happen when building in-tree. Adjust the main nvgpu Makefile to ensure all required paths are part of the system include path so that all headers can be found.

The list of functions is produced by dumping the contents of the gpu_ops substruct of the gk20a struct. This interface makes the assumption that there are only function pointers in gpu_ops.

The lockless allocator was doing a subtraction to determine the correct offset of the element to free. However, this subtraction was using the base address and a numeric offset - not a pointer offset. Thus the difference computed was in bytes not in elements of the block size. The fix is simple: just divide by the block size. Also this modifies the debugging statement a bit so that a bit more information is printed at more useful times. Lastly, a pointer to numeric cast was fixed in the fence code.

* gpu: nvgpu: remove kind map inheritanceSunny He2017-08-14
| | | | | | | | | | | | | | | | | | | | Currently, the kind map initialization inherits from earlier chips' kind map definitions and simply adds on newly supported features. This is dangerous as changes in older architectures may affect newer architectures in unpredictable ways. This patch removes inheritance between subsequent architectures' kind map initializations.

| | | | | | | | | | | | | | | | | | The offset units in the nvgpu_pramin_access_batched() code changes midway through the function. In the first section it is treated as bytes but then in the while-loop iterating over the PRAMIN window and page_alloc_chunks it becomes an offset in words. This patch leaves the offset field in bytes and converts to words where needed.

* gpu: nvgpu: Fix length passed to VIDMEM mapAlex Waterman2017-08-14
| | | | | | | | | | | | | | | | | | The call to __set_pd_level() for vidmem allocs had the wrong length being passed in. This was a silent error since the subsequent __set_pd_level() calls overwrote the bad mappings. However this caused significantly more PDE/PTE writes than necessary since each chunk could be mapped N times where N is the number of chunks in an SGL.

* gpu: nvgpu: gk20a: Fix up qos/sysfs limitsSai Gurrappadi2017-08-11
| | | | | | | | | | | | | | | | | | | | | | | | Userspace sysfs limits devfreq->{min|max}_freq and pmqos min/max limits are treated as the same priority. In case these two ranges don't intersect prefer the max_freq clamp over the min_freq clamp. This is done in order to ensure any thermal throttling isn't bypassed by a userspace sysfs write. MaxQ/MaxP configurations only care about the Fmax limit and not necessarily Fmin, so preferring max_freq over min_freq is consistent with what is required.

It also provides a mechanism by which the HAL code can add extra bits to a GPU physical address based on the attributes passed in. This is necessary during GMMU page table programming. Also remove the flags argument from the various address functions. This flag was used for adding an IO coherence bit to the GPU physical address which is not supported.
