[devel-6.6]vIOMMU: prepare patches to support vIOMMU [P1] · Pull Request !5796 · anolis/cloud-kernel

bugzilla: https://bugzilla.openanolis.cn/show_bug.cgi?id=13617

Backport upstream patches to support vIOMMU:
1. reverted patches that were previously merged from upstream. These patches were not completely backported from the original patch series, causing numerous conflicts during subsequent merges.
2. backported patches from upstream sequentially according to their commit order.

Test cases:

| Case  | ARM  | Intel | AMD  |
|---|---|---|---|
| Build and Boot   | Yes  | Yes  | Yes  |
|  Host FIO test with IOMMU enabled | Yes  |  Yes | Yes  |
| IOMMUFD selttest  |  Yes | Yes (with a knowed fix )  |  Yes (with a knowed fix ) |
|  SVA | / (No supported device)  | Yes (with DSA)  |  / (No supported device) |

NOTE: This PR includes a patch set that deprecate iommu_v2 module.

> AMD GPU driver which was the only in-kernel user of iommu_v2 module is
> removed dependency on iommu_v2 module. These changes are already in
> upstream (v6.6 merge window).
> 
> Also subsequent series will add SVA spuport in AMD IOMMU driver. Device
> drivers are expected to use common SVA framework to enable device
> PASID/PRI features.
