Linux kernel source tree
8477ab1430
Including:
- Core:
- Introduction of iommu-pages infrastructure to consolitate page-table
allocation code among hardware drivers. This is ground-work for more
generalization in the future.
- Remove IOMMU_DEV_FEAT_SVA and IOMMU_DEV_FEAT_IOPF feature flags.
- Convert virtio-iommu to domain_alloc_paging().
- KConfig cleanups.
- Some small fixes for possible overflows and race conditions.
- Intel VT-d driver:
- Restore WO permissions on second-level paging entries.
- Use ida to manage domain id.
- Miscellaneous cleanups.
- AMD-Vi:
- Make sure notifiers finish running before module unload.
- Add support for HTRangeIgnore feature.
- Allow matching ACPI HID devices without matching UIDs.
- ARM-SMMU:
- SMMUv2:
- Recognise the compatible string for SAR2130P MDSS in the Qualcomm
driver, as this device requires an identity domain.
- Fix Adreno stall handling so that GPU debugging is more robust and
doesn't e.g. result in deadlock.
- SMMUv3:
- Fix ->attach_dev() error reporting for unrecognised domains.
- IO-pgtable:
- Allow clients (notably, drivers that process requests from
userspace) to silence warnings when mapping an already-mapped IOVA.
- S390:
- Add support for additional table regions.
- Mediatek:
- Add support for MT6893 MM IOMMU.
- Some smaller fixes and improvements in various other drivers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
