Merge tag 'iommu-fixes-v4.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
"These fixes are all for the AMD IOMMU driver:
- A regression with HSA caused by the conversion of the driver to
default domains. The fixes make sure that an HSA device can still
be attached to an IOMMUv2 domain and that these domains also allow
non-IOMMUv2 capable devices.
- Fix iommu=pt mode which did not work because the dma_ops where set
to nommu_ops, which breaks devices that can only do 32bit DMA.
- Fix an issue with non-PCI devices not working, because there are no
dma_ops for them. This issue was discovered recently as new AMD
x86 platforms have non-PCI devices too"
* tag 'iommu-fixes-v4.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
iommu/amd: Allow non-ATS devices in IOMMUv2 domains
iommu/amd: Set global dma_ops if swiotlb is disabled
iommu/amd: Use swiotlb in passthrough mode
iommu/amd: Allow non-IOMMUv2 devices in IOMMUv2 domains
iommu/amd: Use iommu core for passthrough mode
iommu/amd: Use iommu_attach_group()

* For each block that can be dynamically allocated, it can be either

+ * free:
+ * The block is free.
+ *
+ * pending:
+ * The block is allocated to some client and not free.
+ *
+ * configured:
+ * The block is allocated to some client, and assigned to that
+ * client in MDP5_MDP_SMP_ALLOC registers.
+ *
+ * inuse:
+ * The block is being actively used by a client.
+ *
+ * The updates happen in the following steps:
*
* 1) mdp5_smp_request():
* When plane scanout is setup, calculate required number of
- * blocks needed per client, and request. Blocks not inuse or
- * pending by any other client are added to client's pending
- * set.
+ * blocks needed per client, and request. Blocks neither inuse nor
+ * configured nor pending by any other client are added to client's
+ * pending set.
+ * For shrinking, blocks in pending but not in configured can be freed
+ * directly, but those already in configured will be freed later by
+ * mdp5_smp_commit.
*
* 2) mdp5_smp_configure():
* As hw is programmed, before FLUSH, MDP5_MDP_SMP_ALLOC registers
* are configured for the union(pending, inuse)
+ * Current pending is copied to configured.
+ * It is assumed that mdp5_smp_request and mdp5_smp_configure not run
+ * concurrently for the same pipe.
*
* 3) mdp5_smp_commit():
- * After next vblank, copy pending -> inuse. Optionally update
+ * After next vblank, copy configured -> inuse. Optionally update
* MDP5_SMP_ALLOC registers if there are newly unused blocks
*
+ * 4) mdp5_smp_release():
+ * Must be called after the pipe is disabled and no longer uses any SMB
+ *
* On the next vblank after changes have been committed to hw, the
* client's pending blocks become it's in-use blocks (and no-longer
* in-use blocks become available to other clients).
