* gpu: nvgpu: clk: Fix MISRA 15.6 violationsSrirangan2018-09-05
| | | | | | | | | | | | | | | | | MISRA Rule-15.6 requires that all if-else blocks be enclosed in braces, including single statement blocks. Fix errors due to single statement if blocks without braces by introducing the braces.

* gpu: nvgpu: protect clk_arb init with mutex.Debarshi Dutta2018-09-04
| | | | | | | | | | | | | | | | | | | g->clk_arb is currently initialized as a part of gk20a_finalize_poweron(). Any subsequent call to gk20a_finalize_poweron reinitializes the clk_arb and leading to memory leaks. This is resolved by protecting the g->clk_arb initialization with a mutex clk_arb_enable_lock in struct gk20a. We skip initializing the g->clk_arb if its not NULL.

* gpu: nvgpu: move gp106 specific clk_arbiter code into HALDebarshi Dutta2018-09-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, clock arbiter code is extensively using dgpu specific implementation. This patch restructures the clk_arbiter code and moves gp106 specific code into HAL. Following changes are made in this patch 1) clk_domain_get_f_points is now invoked via HAL for gp106 i.e. g->ops.clk.clk_domain_get_f_points. 2) moved nvgpu_clk_arb_change_vf_point and other related static functions to clk_arb_gp106.c. 3) Instead of only checking if get_arbiter_clk_domain is empty, a check for support_clk_freq_controller is also added. This is to enable the clk_arbiter based on support from both the OS and the chips.

* gpu: nvgpu: handle clk arb event posting in OS specific codeSourab Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mechanism of posting events to userspace 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. The post event functionality on QNX doesn't work on poll though. It uses iofunc_notify_trigger to post the events to the calling process. As such QNX can't work with nvgpu_cond's. To overcome this issue, it is proposed to create OS specific interface function for posting clk arb events. Linux can call nvgpu_cond based implementation, which makes sense since these are already initialized and poll'ed in Linux specific code only. QNX can implement this interface to call iofunc_notify_* functions, as per its need.

They failed to build now that gk20a.h no longer #includes it, so added explit #include.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change solves two problems: (*) the possibility of a crash due to interrupting the gpu initialization following a bind (*) a IOVA memory leak that could prevent the GPU from binding after about 200 bind/unbind cycles A detailed list of fixes: - chek that arbiter is initialized before freeing it. - do not re-enable interrupts when MSI is enabled on unbind. - free the semaphore sea on unbind. - ensure we dont double load the vbios. - check return value of nvgpu_mutex_init for semaphores. - add corresponding nvgpu_mutex_destroy calls. bug 1816516 Change-Id: Ia8af73019e0e1183998855d55bb3eea09672a8b7 Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: http://git-master/r/1465302 Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: Thomas Fleury <tfleury@nvidia.com> Reviewed-by: David Jarrett <djarrett@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1563019 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
