* gpu: nvgpu: vgpu: restructure vgpu clk implementationAparna Das2018-09-20
| | | | | | | | | | | | | | | | Move OS agnostic parts of vgpu clk code out of os/linux specific path. This includes implementation sending rpc commands to RM Server. Move Linux specific vgpu clk code to platform vgpu files keeping it consistent with native implementation.

* gpu: nvgpu: use single lock for gpu power on-offNitin Kumbhar2018-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | Using two separate locks (poweron_lock and poweroff_lock) allows concurrent gpu power-on and power-off. This shall not happen as driver won't be able to maintain correct gpu state. Use a single power_lock to manage gpu power state. This lock will be used to manage gpu power state from multiple triggers like gpu idle, gpu gc-off, etc. JIRA NVGPU-1100 Change-Id: Ia9b4aeda024a5844ae9f182d453cd6341876680a Signed-off-by: Nitin Kumbhar <nkumbhar@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1827812 Reviewed-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-by: svc-misra-checker <svc-misra-checker@nvidia.com> Reviewed-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
