2024-11-08iommu: Pass old domain to set_dev_pasid opYi Liu
To support domain replacement for pasid, the underlying iommu driver needs to know the old domain hence be able to clean up the existing attachment. It would be much convenient for iommu layer to pass down the old domain. Otherwise, iommu drivers would need to track domain for pasids by themselves, this would duplicate code among the iommu drivers. Or iommu drivers would rely group->pasid_array to get domain, which may not always the correct one.

2024-11-05iommu/vt-d: Drain PRQs when domain removed from RIDLu Baolu
As this iommu driver now supports page faults for requests without PASID, page requests should be drained when a domain is removed from the RID2PASID entry. This results in the intel_iommu_drain_pasid_prq() call being moved to intel_pasid_tear_down_entry(). This indicates that when a translation is removed from any PASID entry and the PRI has been enabled on the device, page requests are drained in the domain detachment path. The intel_iommu_drain_pasid_prq() helper has been modified to support sending device TLB invalidation requests for both PASID and non-PASID cases.

2024-11-05iommu/vt-d: Fix checks and print in pgtable_walk()Zhenzhong Duan
There are some issues in pgtable_walk(): 1. Super page is dumped as non-present page 2. dma_pte_superpage() should not check against leaf page table entries 3. Pointer pte is never NULL so checking it is meaningless 4. When an entry is not present, it still makes sense to dump the entry content. Fix 1,2 by checking dma_pte_superpage()'s returned value after level check. Fix 3 by removing pte check. Fix 4 by checking present bit after printing. By this chance, change to print "page table not present" instead of "PTE not present" to be clearer.

There are some issues in dmar_fault_dump_ptes(): 1. return value of phys_to_virt() is used for checking if an entry is present. 2. dump is confusing, e.g., "pasid table entry is not present", confusing by unpresent pasid table vs. unpresent pasid table entry. Current code means the former. 3. pgtable_walk() is called without checking if page table is present. Fix 1 by checking present bit of an entry before dump a lower level entry. Fix 2 by removing "entry" string, e.g., "pasid table is not present". Fix 3 by checking page table present before walk.

2024-11-05iommu/vt-d: Refactor first_level_by_default()Lu Baolu
The first stage page table is compatible across host and guest kernels. Therefore, this driver uses the first stage page table as the default for paging domains. The helper first_level_by_default() determines the feasibility of using the first stage page table based on a global policy. This policy requires consistency in scalable mode and first stage translation capability among all iommu units. However, this is unnecessary as domain allocation, attachment, and removal operations are performed on a per-device basis. The domain type (IOMMU_DOMAIN_DMA vs. IOMMU_DOMAIN_UNMANAGED) should not be a factor in determining the first stage page table usage. Both types are for paging domains, and there's no fundamental difference between them. The driver should not be aware of this distinction unless the core specifies allocation flags that require special handling. Convert first_level_by_default() from global to per-iommu and remove the 'type' input.

This can happen when new callbacks are enqueued from a softirq on an offline CPU before it calls rcutree_report_cpu_dead(). When this happens on NOCB configuration, the rcuog wake-up is deferred through an IPI to an online CPU. This is done to avoid call into the scheduler which can risk arming the RT-bandwidth after hrtimers have been migrated out and disabled. However, doing IPI call from softirq is not allowed: Fix this by forcing deferred rcuog wakeup through the NOCB timer when the CPU is offline" * tag 'rcu.fixes.6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux: rcu/nocb: Fix rcuog wake-up from offline softirq
