* gpu: nvgpu: use also normal logging with TRACE_PRINTKKonsta Holtta2018-03-13
| | | | | | | | | | | | | | | When CONFIG_GK20A_TRACE_PRINTK is set to support printing to ftrace log instead of the normal kernel log, but log_trace from debugfs is not set, fall back to normal kernel logging instead of not logging anything.

* gpu: nvgpu: depend on TRACING for TRACE_PRINTKKonsta Holtta2018-03-13
| | | | | | | | | | | | | | | | | Modify the GK20A_TRACE_PRINTK config such that it depends on TRACING instead of FTRACE_PRINTK. The latter is not in upstream Linux nor in our downstream 4.9, and this option is default n anyway so this is a pretty safe change.

* gpu: nvgpu: decouple sema and hw semaKonsta Holtta2018-03-13
| | | | | | | | | | | | | | | | | | | | | | | | struct nvgpu_semaphore represents (mainly) a threshold value that a sema at some index will get and struct nvgpu_semaphore_int (aka "hw_sema") represents the allocation (and write access) of a semaphore index and the next value that the sema at that index can have. The threshold object doesn't need a pointer to the sema allocation that is not even guaranteed to exist for the whole threshold lifetime, so replace the pointer by the position of the sema in the sema pool. This requires some modifications to pass a hw sema around explicitly because it now represents write access more explicitly. Delete also the index field of semaphore_int because it can be directly derived from the offset in the sema location and is thus unnecessary.

* gpu: nvgpu: support per-channel wdt timeoutsKonsta Holtta2018-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the padding in nvgpu_channel_wdt_args with a timeout value in milliseconds, and add NVGPU_IOCTL_CHANNEL_WDT_FLAG_SET_TIMEOUT to signify the existence of this new field. When the new flag is included in the value of wdt_status, the field is used to set a per-channel timeout to override the per-GPU default. Add NVGPU_IOCTL_CHANNEL_WDT_FLAG_DISABLE_DUMP to disable the long debug dump when a timed out channel gets recovered by the watchdog. Printing the dump to serial console takes easily several seconds. (Note that there is NVGPU_TIMEOUT_FLAG_DISABLE_DUMP about ctxsw timeout separately for NVGPU_IOCTL_CHANNEL_SET_TIMEOUT_EX as well.) The behaviour of NVGPU_IOCTL_CHANNEL_WDT is changed so that either NVGPU_IOCTL_CHANNEL_ENABLE_WDT or NVGPU_IOCTL_CHANNEL_DISABLE_WDT has to be set. The old behaviour was that other values were silently ignored. The usage of the global default debugfs-controlled ch_wdt_timeout_ms is changed so that its value takes effect only for newly opened channels instead of in realtime. Also, zero value no longer means that the watchdog is disabled; there is a separate flag for that after all. gk20a_fifo_recover_tsg used to ignore the value of "verbose" when no engines were found. Correct this.

* gpu: nvgpu: don't reset semaphores to 0 on initKonsta Holtta2018-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With proper wrap-handling comparisons now supported, it's safe to not reset a kernel-managed semaphore to 0 when initializing it to be used by some channel; the value can be left unchanged, so that any pending waits on other channels for this sema can't get corrupted anymore. This makes semaphore values very similar to syncpoints, i.e., just monotonically increasing counters. Also clear the semaphore sea to values of 0xfffffff0 when allocating it. This way it takes 16 increments on each sema to wrap over the 32-bit integer range; such wrapping would eventually happen if the memory was initialized to zeros, so this way any bugs possibly caused by wrapping not taken into account would uncover quickly after boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | The operations in struct nvgpu_sgt_ops have a scatter-gather list (sgl) argument which is a void pointer. Change the type signatures to take struct nvgpu_sgl * which is an opaque marker type that makes it more difficult to pass around wrong arguments, as anything goes for void *. Explicit types add also self-documentation to the code. For some added safety, some explicit type casts are now required in implementors of the nvgpu_sgt_ops interface when converting between the general nvgpu_sgl type and implementation-specific types. This is not purely a bad thing because the casts explain clearly where type conversions are happening.

* gpu: nvgpu: Use our own vmap() for coherent DMA buffersAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | For some reason the GPU does not like the mappings created by the DMA API for coherent sysmem buffers. But a plain vmap() does seem to work. To work around this, when we are using coherent sysmem, force the NO_KERNEL_MAPPING flag to on and then make a vmap() in the nvgpu DMA API wrapper. The rest of the driver will be none the wiser but will work as expected. This problem is not understood yet but it is being tracked in bug 2040115. Once this bug is understood this WAR should either be determined as necessary or reverted with an appropriate fix.

* gpu: nvgpu: Use coherent aperture flagAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a coherent DMA API wee must make sure to program any aperture fields with the coherent aperture setting. To do this the nvgpu_aperture_mask() function was modified to take a third aperture mask argument, a coherent setting, so that code can use this function to generate coherent aperture settings. The aperture choice is some what tricky: the default version of this function uses the state of the DMA API to determine what aperture to use for SYSMEM: either coherent or non-coherent internally. Thus a kernel user need only specify the normal nvgpu_mem struct and the correct mask should be chosen. Due to many uses of nvgpu_mem structs not created directly from the DMA API wrapper it's easier to translate SYSMEM to SYSMEM_COH after creation. However, the GMMU mapping code, will encounter buffers from userspace with difference coerency attributes than the DMA API. Thus the __nvgpu_aperture_mask() really respects the aperture setting passed in regardless of the DMA API state. This aperture setting is pulled from NVGPU_VM_MAP_IO_COHERENT since this is either passed in from userspace or set by the kernel when using coherent DMA. The aperture field in attrs is upgraded to coh if this flag is set. This change also adds a coherent sysmem mask everywhere that it can. There's a couple places that do not have a coherent register field defined yet. These need to eventually be defined and added. Lastly the aperture mask code has been mvoed from the Linux vm.c code to the general vm.c code since this function has no Linux dependencies. Note: depends on https://git-master.nvidia.com/r/1664536 for new register fields.
