Hello Chris Wilson,
The patch e3793468b466: "drm/i915: Use the async worker to avoid
reclaim tainting the ggtt->mutex" from Jan 30, 2020, leads to the
following static checker warning:
drivers/gpu/drm/i915/i915_vma.c:356 i915_vma_wait_for_bind()
warn: 's64max' cannot fit into 'bool'
drivers/gpu/drm/i915/i915_vma.c
345 int i915_vma_wait_for_bind(struct i915_vma *vma)
346 {
347 int err = 0;
348
349 if (rcu_access_pointer(vma->active.excl.fence)) {
350 struct dma_fence *fence;
351
352 rcu_read_lock();
353 fence = dma_fence_get_rcu_safe(&vma->active.excl.fence);
354 rcu_read_unlock();
355 if (fence) {
356 err = dma_fence_wait(fence,
MAX_SCHEDULE_TIMEOUT);
^^^^^^^^^^^^^^^^^^^^
The dma_fence_wait() takes a bool, not a timeout value.
357 dma_fence_put(fence);
358 }
359 }
360
361 return err;
362 }
regards,
dan carpenter
