From 8789cafcfb0d1e16ad0b2c61b047d275f2d684b4 Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Tue, 21 Aug 2018 10:35:06 -0700 Subject: gpu: nvgpu: Standardize HAS_SYNCPOINTs check Nvgpu uses many ways to check if sync points are enabled. The four ways used to be: platform->has_syncpoints g->has_syncpoints nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS) gk20a_platform_has_syncpoints() This patch standardizes all usage to now be nvgpu_has_syncpoints() which is based on gk20a_platform_has_syncpoints() - just renamed to be general to nvgpu. All usage of the other forms have now been consolidated. However, under the hood nvgpu_has_syncpoints() does check the is_enabled flag. This flag is now set where g->has_syncpoints used to be set based on the platform data. The basic dependency chain is this: nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS -> platform->has_syncpoints However, note: there are several places where syncpoints can be disabled if some other driver initialization fails (for ex. host1x). Also note that nvgpu_has_syncpoints() also considers a disable variable set by debugfs.
