* gpu: nvgpu: allow syncfds as prefences on deterministicKonsta Holtta2018-03-23
| | | | | | | | | | | | | | | | | | | | | | Accept submits on deterministic channels even when the prefence is a syncfd, but only if it has just one fence inside. Because NVGPU_SUBMIT_GPFIFO_FLAGS_SYNC_FENCE is shared between pre- and postfences, a postfence (SUBMIT_GPFIFO_FLAGS_FENCE_GET) is not allowed at the same time though. The sync framework is problematic for deterministic channels due to certain allocations that are not controlled by nvgpu. However, that only applies for postfences, yet we've disallowed FLAGS_SYNC_FENCE for deterministic channels even when a postfence is not needed.

* gpu: nvgpu: Abstract get_cycles()Alex Waterman2018-03-16
| | | | | | | | | | | | | | | | | | | | | | | get_cycles is a linux specific API used in common code. This API is being used, it seems, as a method to generate time stamps. So add an API to generate 'high resolution' time stamps. This API returns an opaque time stamp: that is not something one may use directly as a time since in the Linux implementation we just use this cycle counter. Other implementations will, of course, be free to implement as a real time stamp.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Miscellaneous fixes for the sched code: 1. Make sure get_addr() on an SGL respects the use phys flag since the runlist needs physical addresses when NVLINK is in use. 2. Ensure the runlist is contiguous. Since the runlist memory is not virtually addressed the buffer must be physically contiguous. 3. Use all 64 bits of the runlist address in the runlist base addr register (and related fields).

* gpu: nvgpu: Get coherency on gv100 + NVLINK workingAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does a couple of things. First it renames NVGPU_DMA_COHERENT to NVGPU_USE_COHERENT_SYSMEM since the former is somewhat ambiguous in meaning. The latter clearly states what must happen: nvgpu needs to treat sysmem as coherent. This flag does simply follow the state of the DMA API but there's no reason to expect a casual reader of the code to know that when the DMA API is coherent nvgpu must treat sysmem as coherent. One thing to note though: when the dGPU is using PCIe and the PCIe controller is coherent, it doesn't actually matter what we do. However, we use this flag for determining how to make CPU mappings in nvgpu_mem_begin() so this flag is still relevant for the CPU side of things. Next this patch adds a check in the core kernel GMMU mapping routine to make sure that when the NVGPU_USE_COHERENT_SYSMEM flag is set that the IO coherent flag is passed into the mapping code. This is the primary fix that made NVLINK start working. Finally the setting of the USE_COHERENT_SYSMEM flag and the NVGPU_SUPPORT_IO_COHERENCE flag were set both for PCIe and for iGPUs. The iGPU also must correctly match it's CPU mappings and GPU mappings for proper operation.
