From 942029a433390f3385ed9d6fc35476bbf9eafd98 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Mon, 5 Jun 2017 14:25:35 -0700 Subject: gpu: nvgpu: Split non-stall 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 worker. It uses the new MC HALs intr_nonstall (query interrupt status), intr_nonstall_pause (pause interrupts), intr_nonstall_resume (resume interrupts), and is_intr1_pending (query per-engine interrupt bit). MC HAL isr_nonstall is removed, because its work is now handled in chip independent code.
