From 8ee3aa4b3175d8d27e57a0f5d5e2cdf3d78a4a58 Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Tue, 24 Jan 2017 19:00:42 +0530 Subject: gpu: nvgpu: use common nvgpu mutex/spinlock APIs Instead of using Linux APIs for mutex and spinlocks directly, use new APIs defined in Replace Linux specific mutex/spinlock declaration, init, lock, unlock APIs with new APIs e.g struct mutex is replaced by struct nvgpu_mutex and mutex_lock() is replaced by nvgpu_mutex_acquire() And also include instead of including and Add explicit nvgpu/lock.h includes to below files to fix complilation failures. gk20a/platform_gk20a.h include/nvgpu/allocator.h Jira NVGPU-13 Change-Id: I81a05d21ecdbd90c2076a9f0aefd0e40b215bd33 Signed-off-by: Deepak Nibade Reviewed-on: http://git-master/r/1293187 Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/lpwr/lpwr.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/gpu/nvgpu/lpwr/lpwr.c') diff --git a/drivers/gpu/nvgpu/lpwr/lpwr.c b/drivers/gpu/nvgpu/lpwr/lpwr.c index 9636891b..b722a900 100644 --- a/drivers/gpu/nvgpu/lpwr/lpwr.c +++ b/drivers/gpu/nvgpu/lpwr/lpwr.c @@ -346,7 +346,7 @@ int nvgpu_lpwr_enable_pg(struct gk20a *g, bool pstate_lock) if (pstate_lock) nvgpu_clk_arb_pstate_change_lock(g, true); - mutex_lock(&pmu->pg_mutex); + nvgpu_mutex_acquire(&pmu->pg_mutex); present_pstate = nvgpu_clk_arb_get_current_pstate(g); @@ -367,7 +367,7 @@ int nvgpu_lpwr_enable_pg(struct gk20a *g, bool pstate_lock) status = gk20a_pmu_enable_elpg(g); } - mutex_unlock(&pmu->pg_mutex); + nvgpu_mutex_release(&pmu->pg_mutex); if (pstate_lock) nvgpu_clk_arb_pstate_change_lock(g, false); @@ -386,7 +386,7 @@ int nvgpu_lpwr_disable_pg(struct gk20a *g, bool pstate_lock) if (pstate_lock) nvgpu_clk_arb_pstate_change_lock(g, true); - mutex_lock(&pmu->pg_mutex); + nvgpu_mutex_acquire(&pmu->pg_mutex); present_pstate = nvgpu_clk_arb_get_current_pstate(g); @@ -411,7 +411,7 @@ int nvgpu_lpwr_disable_pg(struct gk20a *g, bool pstate_lock) } exit_unlock: - mutex_unlock(&pmu->pg_mutex); + nvgpu_mutex_release(&pmu->pg_mutex); if (pstate_lock) nvgpu_clk_arb_pstate_change_lock(g, false); -- cgit v1.2.2
