At a few points in our uABI, we check to see if the driver is wedged and report -EIO back to the user in that case. However, as we perform the check and reset asynchronously (where once before they were both serialised by the struct_mutex), we may instead see the temporary wedging used to cancel inflight rendering to avoid a deadlock during reset (caused by either us timing out in our reset handler, i915_wedge_on_timeout or with malice aforethought in intel_reset_prepare for a stuck modeset). If we suspect this is the case, that is we see a wedged driver *and* reset in progress, then wait until the reset is resolved before reporting upon the wedged status. v2: might_sleep() (Mika) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109580 Signed-off-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Mika Kuoppala <mika.kuoppala@xxxxxxxxxxxxxxx> Reviewed-by: Mika Kuoppala <mika.kuoppala@xxxxxxxxxxxxxxx> --- drivers/gpu/drm/i915/i915_debugfs.c | 17 +++++++---- drivers/gpu/drm/i915/i915_drv.h | 7 ++++- drivers/gpu/drm/i915/i915_gem.c | 25 ++++++++-------- drivers/gpu/drm/i915/i915_request.c | 5 ++-- drivers/gpu/drm/i915/i915_reset.c | 29 +++++++++++++++++-- drivers/gpu/drm/i915/i915_reset.h | 2 ++ drivers/gpu/drm/i915/intel_engine_cs.c | 8 ++--- drivers/gpu/drm/i915/intel_hangcheck.c | 2 +- drivers/gpu/drm/i915/selftests/huge_pages.c | 2 +- drivers/gpu/drm/i915/selftests/i915_active.c | 2 +- .../drm/i915/selftests/i915_gem_coherency.c | 4 +-- .../gpu/drm/i915/selftests/i915_gem_context.c | 2 +- .../gpu/drm/i915/selftests/i915_gem_evict.c | 2 +- .../gpu/drm/i915/selftests/i915_gem_object.c | 2 +- drivers/gpu/drm/i915/selftests/i915_request.c | 2 +- .../gpu/drm/i915/selftests/igt_flush_test.c | 2 +- .../gpu/drm/i915/selftests/intel_hangcheck.c | 24 +++++++-------- drivers/gpu/drm/i915/selftests/intel_lrc.c | 2 +- .../drm/i915/selftests/intel_workarounds.c | 4 +-- 19 files changed, 91 insertions(+), 52 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 2aeea977283f..37175414ce89 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -3833,11 +3833,18 @@ static const struct file_operations i915_cur_wm_latency_fops = { static int i915_wedged_get(void *data, u64 *val) { - struct drm_i915_private *dev_priv = data; - - *val = i915_terminally_wedged(&dev_priv->gpu_error); + int ret = i915_terminally_wedged(data); - return 0; + switch (ret) { + case -EIO: + *val = 1; + return 0; + case 0: + *val = 0; + return 0; + default: + return ret; + } } static int @@ -3918,7 +3925,7 @@ i915_drop_caches_set(void *data, u64 val) mutex_unlock(&i915->drm.struct_mutex); } - if (val & DROP_RESET_ACTIVE && i915_terminally_wedged(&i915->gpu_error)) + if (val & DROP_RESET_ACTIVE && i915_terminally_wedged(i915)) i915_handle_error(i915, ALL_ENGINES, 0, NULL); fs_reclaim_acquire(GFP_KERNEL); diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 58c9058da4b4..2a78fb3e6eee 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -3020,11 +3020,16 @@ int __must_check i915_gem_set_global_seqno(struct drm_device *dev, u32 seqno); struct i915_request * i915_gem_find_active_request(struct intel_engine_cs *engine); -static inline bool i915_terminally_wedged(struct i915_gpu_error *error) +static inline bool __i915_wedged(struct i915_gpu_error *error) { return unlikely(test_bit(I915_WEDGED, &error->flags)); } +static inline bool i915_reset_failed(struct drm_i915_private *i915) +{ + return __i915_wedged(&i915->gpu_error); +} + static inline u32 i915_reset_count(struct i915_gpu_error *error) { return READ_ONCE(error->reset_count); diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index b421bc7a2e26..cc88e7974422 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -1928,7 +1928,7 @@ vm_fault_t i915_gem_fault(struct vm_fault *vmf) * fail).
