* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
| | | | | | | | | | | | | | | Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent. JIRA NVGPU-598 JIRA NVGPU-601 Change-Id: Ib7f2a43d3688bb0d0b7dcc48469a6783fd988ce9 Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1747714 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: Remove gk20a_dbg* functionsTerje Bergstrom2018-05-09
| | | | | | | | | | | | | | | Switch all logging to nvgpu_log*(). gk20a_dbg* macros are intentionally left there because of use from other repositories. Because the new functions do not work without a pointer to struct gk20a, and piping it just for logging is excessive, some log messages are deleted.

* gpu: nvgpu: add HAL to handle nonstall interruptsDeepak Nibade2018-05-07
| | | | | | | | | | | | | | | | | | | | | Add new HAL gops.mc.isr_nonstall() to handle nonstall interrupts We already handle nonstall interrupts in nvgpu_intr_nonstall() But this API is completely in linux specific code Separate out os-independent code to handle nonstall interrupts in new API mc_gk20a_isr_nonstall() and set it to HAL gops.mc.isr_nonstall() for all existing chips Call this HAL from nvgpu_intr_nonstall() Jira NVGPUT-8 Change-Id: Iec6a56db03158a72a256f7eee8989a0a8a42ae2f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1706589 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: add gops.semaphore_wakeup HALRichard Zhao2018-03-06
| | | | | | | | | | | | | | | | | vserver handles semaphore differently from native, so it needs a callback to differentiate from native. Also created common function mc_gk20a_handle_intr_nonstall to handle all nonstall interrupts.

* gpu: nvgpu: Move isr related fields from gk20aTerje Bergstrom2017-08-03
| | | | | | | | | | | | | | | | | Move fields in struct gk20a related to interrupt handling into Linux specific nvgpu_os_linux. At the same time move the counter logic from function in HAL into Linux specific code, and two Linux specific power management functions from generic gk20a.c to Linux specific module.c.

* gpu: nvgpu: Split non-stall interrupt handlingTerje Bergstrom2017-06-07
| | | | | | | | | | | | | | | | | | | | | | Split handling of stalling interrupt to Linux specific chip agnostic and OS independent chip specific parts. Linux specific chip independent part contains handler for ISR and passing the control to a bottom half worker. It uses the new MC HALs intr_nonstall (query interrupt status), intr_nonstall_pause (pause interrupts), intr_nonstall_resume (resume interrupts), and is_intr1_pending (query per-engine interrupt bit). MC HAL isr_nonstall is removed, because its work is now handled in chip independent code.

Linux specific chip independent part contains handler for ISR and passing the control to a bottom half. It uses the new MC HALs intr_stall (query interrupt status), intr_pause (pause interrupts) and intr_resume (resume interrupts). MC HAL isr_stall now returns void and gets called in thread context and thus remove isr_thread_stall and replace the implementation with isr_stall.
