* gpu: nvgpu: cache gpu clk rateArun Kannan2018-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | Cache the rate used in clk_set_rate(). Return that cached rate on clk_get_rate(), don't read from hardware. This cached rate is used to avoid duplicate requests to clk_set_rate(). Motivation is to support multiple governors for gpu clk. Reading clock from hardware is unreliable in multi-governor situation. Relying on hardware clock value could mislead the kernel gpu governor in its scaling calculations.

* gpu: nvgpu: sync_framework cleanupsDebarshi Dutta2018-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deals with cleanups meant to make things simpler for the upcoming os abstraction patches for the sync framework. This patch causes some substantial changes which are listed out as follows. 1) sync_timeline is moved out of gk20a_fence into struct nvgpu_channel_linux. New function pointers are created to facilitate os independent methods for enabling/disabling timeline and are now named as os_fence_framework. These function pointers are located in the struct os_channel under struct gk20a. 2) construction of the channel_sync require nvgpu_finalize_poweron_linux() to be invoked before invocations to nvgpu_init_mm_ce_context(). Hence, these methods are now moved away from gk20a_finalize_poweron() and invoked after nvgpu_finalize_poweron_linux(). 3) sync_fence creation is now delinked from fence construction and move to the channel_sync_gk20a's channel_incr methods. These sync_fences are mainly associated with post_fences. 4) In case userspace requires the sync_fences to be constructed, we try to obtain an fd before the gk20a_channel_submit_gpfifo() instead of trying to do that later. This is used to avoid potential after effects of duplicate work submission due to failure to obtain an unused fd.

* gpu: nvgpu: post dbg session event from os specific codeSourab Gupta2018-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of debug session unification following changes are required. -Including bug.h header file to fix the compilation issue on QNX - The mechanism of posting debug events is OS specific. In Linux this works through poll fd, wherein we can make use of nvgpu_cond variables to poll and trigger the corresponding wait_queue via nvgpu_cond_broadcast_interruptible() call. The post event functionality on QNX doesn't work on poll though. It uses iofunc_notify_trigger to post the debug events to calling process. As such QNX can't work with nvgpu_cond's. To overcome this issue, it is proposed to create a OS specific interface for posting debugger events. Linux can call nvgpu_cond_broadcast_interruptible() in its implementation, which makes sense since these are already initialized and poll'ed in the Linux specific code only. QNX can implement this interface to call iofunc_notify_* functions, as per its need Jira VQRM-2363 Change-Id: I0abdc0787f771040b8aff5384290d7e6549f81fb Signed-off-by: Sourab Gupta <sourabg@nvidia.com> Signed-off-by: Prateek Sethi <prsethi@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1696368 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: Richard Zhao <rizhao@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
