* gpu: nvgpu: Don't ioremap() regs when using POSIXAlex Waterman2018-03-16
| | | | | | | | | | | | | | | | | | | | | When __NVGPU_POSIX__ is defined do no use ioremap(). This operation probably doesn't make much sense. Currently we have no plans to run the driver in userspace against a real GPU, hence programming the nvlink credits registers is simply not necessary. Also fix an unused variable by returing it as an error.

* 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.

* gpu: nvgpu: wait for all prefence semas on gpuKonsta Holtta2018-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pre-fence wait for semaphores in the submit path has supported a fast path for fences that have only one underlying semaphore. The fast path just inserts the wait on this sema to the pushbuffer directly. For other fences, the path has been using a CPU wait indirection, signaling another semaphore when we get the CPU-side callback. Instead of only supporting prefences with one sema, unroll all the individual semaphores and insert waits for each to a pushbuffer, like we've already been doing with syncpoints. Now all sema-backed syncs get the fast path. This simplifies the logic and makes it more explicit that only foreign fences need the CPU wait. There is no need to hold references to the sync fence or the semas inside: this submitted job only needs the global read-only sema mapping that is guaranteed to stay alive while the VM of this channel stays alive, and the job does not outlive this channel.

* gpu: nvgpu: Pass correct va_allocated field in .gmmu_unmap()Alex Waterman2018-03-14
| | | | | | | | | | | | | | | | | | | | | When nvgpu maps an nvgpu_mem struct the nvgpu driver has a choice of either using a fixed or non-fixed mapping. For non-fixed mappings the GMMU APIs allocate a VA space for the caller. In that case the GMMU APIs must also free that VA range when nvgpu unmaps the nvgpu_mem. For fixed mappings the GMMU APIs must instead not manage the life time of the VA space. To support these two possibilities add a field to nvgpu_mem that specifies whether the GMMU APIs must or must not free the GPU VA range during the GMMU unmap operation. Also fix a case in the nvgpu vm_area code that would double free a VA allocation in some cases (sparse allocs).

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.

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