When allocating a user iommufd_hw_pagetable, the user space is allowed to associate a fault object with the hw_pagetable by specifying the fault object ID in the page table allocation data and setting the IOMMU_HWPT_FAULT_ID_VALID flag bit. On a successful return of hwpt allocation, the user can retrieve and respond to page faults by reading and writing the file interface of the fault object. Once a fault object has been associated with a hwpt, the hwpt is iopf-capable, indicated by hwpt->fault is non NULL. Attaching, detaching, or replacing an iopf-capable hwpt to an RID or PASID will differ from those that are not iopf-capable.

Add iopf-capable hw page table attach/detach/replace helpers. The pointer to iommufd_device is stored in the domain attachment handle, so that it can be echo'ed back in the iopf_group. The iopf-capable hw page tables can only be attached to devices that support the IOMMU_DEV_FEAT_IOPF feature. On the first attachment of an iopf-capable hw_pagetable to the device, the IOPF feature is enabled on the device. Similarly, after the last iopf-capable hwpt is detached from the device, the IOPF feature is disabled on the device. The current implementation allows a replacement between iopf-capable and non-iopf-capable hw page tables. This matches the nested translation use case, where a parent domain is attached by default and can then be replaced with a nested user domain with iopf support.

An iommufd fault object provides an interface for delivering I/O page faults to user space. These objects are created and destroyed by user space, and they can be associated with or dissociated from hardware page table objects during page table allocation or destruction. User space interacts with the fault object through a file interface. This interface offers a straightforward and efficient way for user space to handle page faults. It allows user space to read fault messages sequentially and respond to them by writing to the same file. The file interface supports reading messages in poll mode, so it's recommended that user space applications use io_uring to enhance read and write efficiency. A fault object can be associated with any iopf-capable iommufd_hw_pgtable during the pgtable's allocation. All I/O page faults triggered by devices when accessing the I/O addresses of an iommufd_hw_pgtable are routed through the fault object to user space. Similarly, user space's responses to these page faults are routed back to the iommu device driver through the same fault object.

iommu_hwpt_pgfaults represent fault messages that the userspace can retrieve. Multiple iommu_hwpt_pgfaults might be put in an iopf group, with the IOMMU_PGFAULT_FLAGS_LAST_PAGE flag set only for the last iommu_hwpt_pgfault. An iommu_hwpt_page_response is a response message that the userspace should send to the kernel after finishing handling a group of fault messages. The @dev_id, @pasid, and @grpid fields in the message identify an outstanding iopf group for a device. The @cookie field, which matches the cookie field of the last fault in the group, will be used by the kernel to look up the pending message.

Unlike the SVA case where each PASID of a device has an SVA domain attached to it, the I/O page faults are handled by the fault handler of the SVA domain. The I/O page faults for a user page table might be handled by the domain attached to RID or the domain attached to the PASID, depending on whether the PASID table is managed by user space or kernel. As a result, there is a need for the domain attach group interfaces to have attach handle support. The attach handle will be forwarded to the fault handler of the user domain. Add some variants of the domain attaching group interfaces so that they could support the attach handle and export them for use in IOMMUFD.

Previously, the domain that a page fault targets is stored in an iopf_group, which represents a minimal set of page faults. With the introduction of attach handle, replace the domain with the handle so that the fault handler can obtain more information as needed when handling the faults. iommu_report_device_fault() is currently used for SVA page faults, which handles the page fault in an internal cycle. The domain is retrieved with iommu_get_domain_for_dev_pasid() if the pasid in the fault message is valid. This doesn't work in IOMMUFD case, where if the pasid table of a device is wholly managed by user space, there is no domain attached to the PASID of the device, and all page faults are forwarded through a NESTING domain attaching to RID. Add a static flag in iommu ops, which indicates if the IOMMU driver supports user-managed PASID tables. In the iopf deliver path, if no attach handle found for the iopf PASID, roll back to RID domain when the IOMMU driver supports this capability. iommu_get_domain_for_dev_pasid() is no longer used and can be removed.

The struct sva_iommu represents an association between an SVA domain and a PASID of a device. It's stored in the iommu group's pasid array and also tracked by a list in the per-mm data structure.

Currently, when attaching a domain to a device or its PASID, domain is stored within the iommu group. It could be retrieved for use during the window between attachment and detachment. With new features introduced, there's a need to store more information than just a domain pointer. This information essentially represents the association between a domain and a device. For example, the SVA code already has a custom struct iommu_sva which represents a bond between sva domain and a PASID of a device. Looking forward, the IOMMUFD needs a place to store the iommufd_device pointer in the core, so that the device object ID could be quickly retrieved in the critical fault handling path. Introduce domain attachment handle that explicitly represents the attachment relationship between a domain and a device or its PASID.

At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected. The touchscreen reports a battery status of 0% and jumps to 1% when a stylus is used. The device ID was added and the battery ignore quirk was enabled for it.

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s shares the VCC33 supply with other peripherals that may remain powered during suspend (e.g. when enabled as wakeup sources). The reset line is also wired so that it can be left deasserted when the supply is off. This is important as it avoids holding the controller in reset for extended periods of time when it remains powered, which can lead to increased power consumption, and also avoids leaking current through the X13s reset circuitry during suspend (and after driver unbind). Use the new 'no-reset-on-power-off' devicetree property to determine when reset needs to be asserted on power down. Notably this also avoids wasting power on machine variants without a touchscreen for which the driver would otherwise exit probe with reset asserted.

When the power supply is shared with other peripherals the reset line can be wired in such a way that it can remain deasserted regardless of whether the supply is on or not. This is important as it can be used to avoid holding the controller in reset for extended periods of time when it remains powered, something which can lead to increased power consumption. Leaving reset deasserted also avoids leaking current through the reset circuitry pull-up resistors. Add a new 'no-reset-on-power-off' devicetree property which can be used by the OS to determine when reset needs to be asserted on power down. Note that this property can also be used when the supply cannot be turned off by the OS at all.

Add a compatible string for the Elan eKTH5015M touch controller. Judging from the current binding and commit bd3cba00 ("HID: i2c-hid: elan: Add support for Elan eKTH6915 i2c-hid touchscreens"), eKTH5015M appears to be compatible with eKTH6915. Notably the power-on sequence is the same. While at it, drop a redundant label from the example.

The Ilitek ILI2901 touch screen controller was apparently incorrectly added to the Elan eKTH6915 schema simply because it also has a reset gpio and is currently managed by the Elan driver in Linux. The two controllers are not related even if an unfortunate wording in the commit message adding the Ilitek compatible made it sound like they were. Add a dedicated schema for the ILI2901 which does not specify the I2C address (which is likely 0x41 rather than 0x10 as for other Ilitek touch controllers) to avoid cluttering the Elan schema with unrelated devices and to make it easier to find the correct schema when adding further Ilitek controllers.
