From 726900b8433294fd89a6d730d2fec9de8e33afda Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Thu, 11 May 2017 13:12:03 -0700 Subject: gpu: nvgpu: Split stalling interrupt handling 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. 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.
