git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd updates from Jason Gunthorpe:
- The iova_bitmap logic for efficiently reporting dirty pages back to
userspace has a few more tricky corner case bugs that have been
resolved and backed with new tests.
The revised version has simpler logic.
- Shared branch with iommu for handle support when doing domain attach.
Handles allow the domain owner to include additional private data on
a per-device basis.
- IO Page Fault Reporting to userspace via iommufd. Page faults can be
generated on fault capable HWPTs when a translation is not present.
Routing them to userspace would allow a VMM to be able to virtualize
them into an emulated vIOMMU. This is the next step to fully enabling
vSVA support.

The LS7A chipset can be used as part of a PCIe Root Complex with
Loongson-3C6000 and similar CPUs. In this case, DEV_LS7A_PCIE_PORT5 has a
PCI_CLASS_BRIDGE_HOST class code, and it is a Type 0 Function whose config
space provides access to Root Complex registers.
The DEV_LS7A_PCIE_PORT5 has an MSI Capability, and its MSI Enable bit must
be set before other devices below the Root Complex can use MSI. This is
not the standard PCI behavior of MSI Enable, so the normal PCI MSI code
does not set it.
Set the DEV_LS7A_PCIE_PORT5 MSI Enable bit via a quirk so other devices
below the Root Complex can use MSI.

This commit introduces a new 'I' mode for dm-integrity.
The 'I' mode may be selected if the underlying device has non-power-of-2
sector size. In this mode, dm-integrity will store integrity data
directly in device's sectors and it will not use journal.
This mode improves performance and reduces flash wear because there would
be no journal writes.

This is a partial revert of commit
8117961d98f ("x86/efi: Disregard setup header of loaded image")
which triggers boot issues on older Dell laptops. As it turns out,
switching back to a heap allocation for the struct boot_params
constructed by the EFI stub works around this, even though it is unclear
why.

Similarly to PCI where msi-map/msi-mask are used to compute the full RID
(aka DID in ITS speak), use the msi-parent as the discovery mechanism,
since there is no way a device can generally express its ID.
However, since switching to a per-device MSI domain model, the domain
passed to its_pmsi_prepare() is the wrong one, and points to the device's
instead of the ITS'. Bad.
Use the parent domain instead, which is the ITS domain.

Since 6adb35ff43a16 ("irqchip/gic-v3-its: Provide MSI parent for
PCI/MSI[-X]"), the primary domain a PCI device allocates its interrupts
from is the one that is directly attached to the device itself.
By virtue of being a PCI device, it has no OF node.
This domain is (through more layer than it is worth describing)
passed to its_pci_msi_prepare(), which tries to compute the
full RID that is presented to the ITS by the device. This is ultimately
done by calling pci_msi_domain_get_msi_rid(), passing both the
domain and the PCI device as arguments.
The baked-in assumption is that either the domain that is passed
to pci_msi_domain_get_msi_rid() describes an interrupt controller
with either an OF node or an entry in an ACPI IORT table.
In this case, it is *neither*. This domain is does not represent
anything firmware-based, but just an allocation unit for the device.
As a result, it fails to provide the full RID (which requires inspecting
the msi-map/msi-mask properties in the DT), and stick to the BDF, which
isn't very useful.
Tragedy follows with a litany of devices that randomly die as they fail to
see any MSI (because the RID is wrong) or fail to get an allocation
(because they try to steal LPIs from their neighbour's pool).
This will happen on any system where a single ITS is shared by multiple
root ports and end-points with overlapping BDF numbers, and has the
topology described in the device-tree. Simpler DT topologies will luckily
work, and so will ACPI-based systems.
Solve it by pointing pci_msi_domain_get_msi_rid() at the *parent* domain,
which is the ITS, resulting in a correct mapping and a restored happiness
in my personal zoo.
