* gpu: nvgpu: Disable trace_printk use by defaultTerje Bergstrom2017-03-07
| | | | | | | | | | | | | | | trace_printk() does an extra stringify operation before calling do_trace_printk(). The string ends up unused. This has an impact to kernel even if we never end up using trace_printk(). Disable use of trace_printk() and introduce a Kconfig option for re-enabling it.

* gpu: nvgpu: Organize semaphore_gk20a.[ch]Alex Waterman2017-02-13
| | | | | | | | | | | | | | | | | | | | | | | Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore code is common to all chips. Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu and rename it to semaphore.h. Also update all places where the header is inluced to use the new path. This revealed an odd location for the enum gk20a_mem_rw_flag. This should be in the mm headers. As a result many places that did not need anything semaphore related had to include the semaphore header file. Fixing this oddity allowed the semaphore include to be removed from many C files that did not need it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove including gk20a.h from pmu_gk20a.h. This causes a fallout as some #includes were missing. gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the include. Including mm_gk20a.h in gr_gp10b.h causes recursive include, as mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to remove the dependency. gr_ctx_gk20a.h used struct gk20a pointers, but did not forward declare it. Add a forward declaration. gr_gk20a.h uses dbg_session_gk20a, but was missing forward declaration. gr_gk20a.h did not include nvgpu.h but it uses preemption types from that header. Add include.

| | | | | | | | | | | | | | | | | | | | | | | | In gp10b_ce_nonstall_isr(), we trigger a semaphore wakeup. Currently, we clear the interrupt status register after the wakeup is complete. There is potential for an interrupt to come in while the wake-up operation is in progress, and it is possible that: 1) We miss processing the interrupt in that ISR iteration AND 2) We clear the interrupt status register anyways This change clears the status register before triggering wakeup, so the interrupt will properly re-fire.
