From ae2e28b02630072134392e75b1062eef69aeeff8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 22 Oct 2019 15:19:35 +0100 Subject: [PATCH] drm/i915: Teach record_defaults to operate on the intel_gt Again we wish to operate on the engines, which are owned by the intel_gt. As such it is easier, and much more consistent, to pass the intel_gt parameter. v2: Unexport i915_gem_load_power_context() Signed-off-by: Chris Wilson Cc: Tvrtko Ursulin Reviewed-by: Tvrtko Ursulin Link: https://patchwork.freedesktop.org/patch/msgid/20191022141935.15733-1-chris@chris-wilson.co.uk --- drivers/gpu/drm/i915/gem/i915_gem_pm.c | 7 +------ drivers/gpu/drm/i915/gem/i915_gem_pm.h | 1 - drivers/gpu/drm/i915/i915_gem.c | 14 ++++++++------ drivers/gpu/drm/i915/selftests/i915_selftest.c | 13 +++++++++++-- 4 files changed, 20 insertions(+), 15 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_pm.c b/drivers/gpu/drm/i915/gem/i915_gem_pm.c index ee3279c..9bc0cf3 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_pm.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_pm.c @@ -37,11 +37,6 @@ static bool switch_to_kernel_context_sync(struct intel_gt *gt) return result; } -bool i915_gem_load_power_context(struct drm_i915_private *i915) -{ - return switch_to_kernel_context_sync(&i915->gt); -} - static void user_forcewake(struct intel_gt *gt, bool suspend) { int count = atomic_read(>->user_wakeref); @@ -171,7 +166,7 @@ void i915_gem_resume(struct drm_i915_private *i915) intel_uc_resume(&i915->gt.uc); /* Always reload a context for powersaving. */ - if (!i915_gem_load_power_context(i915)) + if (!switch_to_kernel_context_sync(&i915->gt)) goto err_wedged; user_forcewake(&i915->gt, false); diff --git a/drivers/gpu/drm/i915/gem/i915_gem_pm.h b/drivers/gpu/drm/i915/gem/i915_gem_pm.h index a0175727..26b78db 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_pm.h +++ b/drivers/gpu/drm/i915/gem/i915_gem_pm.h @@ -12,7 +12,6 @@ struct drm_i915_private; struct work_struct; -bool i915_gem_load_power_context(struct drm_i915_private *i915); void i915_gem_resume(struct drm_i915_private *i915); void i915_gem_idle_work_handler(struct work_struct *work); diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index e86f0a4..319e96d 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -48,6 +48,7 @@ #include "gt/intel_engine_user.h" #include "gt/intel_gt.h" #include "gt/intel_gt_pm.h" +#include "gt/intel_gt_requests.h" #include "gt/intel_mocs.h" #include "gt/intel_reset.h" #include "gt/intel_renderstate.h" @@ -1069,7 +1070,7 @@ void i915_gem_sanitize(struct drm_i915_private *i915) intel_runtime_pm_put(&i915->runtime_pm, wakeref); } -static int __intel_engines_record_defaults(struct drm_i915_private *i915) +static int __intel_engines_record_defaults(struct intel_gt *gt) { struct i915_request *requests[I915_NUM_ENGINES] = {}; struct intel_engine_cs *engine; @@ -1085,7 +1086,7 @@ static int __intel_engines_record_defaults(struct drm_i915_private *i915) * from the same default HW values. */ - for_each_engine(engine, i915, id) { + for_each_engine(engine, gt, id) { struct intel_context *ce; struct i915_request *rq; @@ -1093,7 +1094,8 @@ static int __intel_engines_record_defaults(struct drm_i915_private *i915) GEM_BUG_ON(!engine->kernel_context); engine->serial++; /* force the kernel context switch */ - ce = intel_context_create(i915->kernel_context, engine); + ce = intel_context_create(engine->kernel_context->gem_context, + engine); if (IS_ERR(ce)) { err = PTR_ERR(ce); goto out; @@ -1122,7 +1124,7 @@ err_rq: } /* Flush the default context image to memory, and enable powersaving. */ - if (!i915_gem_load_power_context(i915)) { + if (intel_gt_wait_for_idle(gt, I915_GEM_IDLE_TIMEOUT) == -ETIME) { err = -EIO; goto out; } @@ -1181,7 +1183,7 @@ out: * this is by declaring ourselves wedged. */ if (err) - intel_gt_set_wedged(&i915->gt); + intel_gt_set_wedged(gt); for (id = 0; id < ARRAY_SIZE(requests); id++) { struct intel_context *ce; @@ -1295,7 +1297,7 @@ int i915_gem_init(struct drm_i915_private *dev_priv) if (ret) goto err_gt; - ret = __intel_engines_record_defaults(dev_priv); + ret = __intel_engines_record_defaults(&dev_priv->gt); if (ret) goto err_gt; diff --git a/drivers/gpu/drm/i915/selftests/i915_selftest.c b/drivers/gpu/drm/i915/selftests/i915_selftest.c index 825a828..92c9193 100644 --- a/drivers/gpu/drm/i915/selftests/i915_selftest.c +++ b/drivers/gpu/drm/i915/selftests/i915_selftest.c @@ -23,8 +23,9 @@ #include -#include "../i915_drv.h" -#include "../i915_selftest.h" +#include "gt/intel_gt_pm.h" +#include "i915_drv.h" +#include "i915_selftest.h" #include "igt_flush_test.h" @@ -256,6 +257,10 @@ int __i915_live_setup(void *data) { struct drm_i915_private *i915 = data; + /* The selftests expect an idle system */ + if (intel_gt_pm_wait_for_idle(&i915->gt)) + return -EIO; + return intel_gt_terminally_wedged(&i915->gt); } @@ -275,6 +280,10 @@ int __intel_gt_live_setup(void *data) { struct intel_gt *gt = data; + /* The selftests expect an idle system */ + if (intel_gt_pm_wait_for_idle(gt)) + return -EIO; + return intel_gt_terminally_wedged(gt); } -- 2.7.4
