Hi,
I am trying to do some tests for kernel 4.1.0-next-20150626+, but
panic in amd_iommu_attach_dev. After some digging inside amd_iommu.c,
I found the suspecting code:
diff --git a/drivers/iommu/amd_iommu.c b/drivers/iommu/amd_iommu.c
index d3e5e9a..4f6da17 100644
--- a/drivers/iommu/amd_iommu.c
+++ b/drivers/iommu/amd_iommu.c
@@ -1882,6 +1882,7 @@ static struct dma_ops_domain *dma_ops_domain_alloc(void)
return NULL;
spin_lock_init(&dma_dom->domain.lock);
+ mutex_init(&dma_dom->domain.api_lock);
When I initialize the api_lock, then I can go forward with another problem.
Thanks,
George
