From bb7ed28ab17ce68c71838bc2aa3fd6e2a0a71a15 Mon Sep 17 00:00:00 2001 From: Sourab Gupta Date: Tue, 1 May 2018 18:11:14 +0530 Subject: gpu: nvgpu: add worker for clk arb work handling Implement a worker thread to replace the workqueue based handling for clk arbiter update callbacks. The work items scheduled with the thread are of two types, update_vf_table and arb_update. Previously, there were two workqueues for handling these two work struct's separately. Now the single worker thread would process these two events. If a work item of a particular type is scheduled to be run on the worker, another instance of same type won't be scheduled, which mirrors the linux workqueue behavior. This also removes dependency on linux workqueues/work struct and makes code portable to be used by QNX also.
