2024-03-08iommu/amd: Fix sleeping in atomic contextVasant Hegde
Commit cf70873e3d01 ("iommu/amd: Refactor GCR3 table helper functions") changed GFP flag we use for GCR3 table. Original plan was to move GCR3 table allocation outside spinlock. But this requires complete rework of attach device path. Hence we didn't do it as part of SVA series. For now revert the GFP flag to ATOMIC (same as original code).

2024-02-16iommu/amd: Mark interrupt as managedMario Limonciello
On many systems that have an AMD IOMMU the following sequence of warnings is observed during bootup. ``` pci 0000:00:00.2 can't derive routing for PCI INT A pci 0000:00:00.2: PCI INT A: not connected ``` This series of events happens because of the IOMMU initialization sequence order and the lack of _PRT entries for the IOMMU. During initialization the IOMMU driver first enables the PCI device using pci_enable_device(). This will call acpi_pci_irq_enable() which will check if the interrupt is declared in a PCI routing table (_PRT) entry. According to the PCI spec [1] these routing entries are only required under PCI root bridges: The _PRT object is required under all PCI root bridges The IOMMU is directly connected to the root complex, so there is no parent bridge to look for a _PRT entry. The first warning is emitted since no entry could be found in the hierarchy. The second warning is then emitted because the interrupt hasn't yet been configured to any value. The pin was configured in pci_read_irq() but the byte in PCI_INTERRUPT_LINE return 0xff which means "Unknown". After that sequence of events pci_enable_msi() is called and this will allocate an interrupt. That is both of these warnings are totally harmless because the IOMMU uses MSI for interrupts. To avoid even trying to probe for a _PRT entry mark the IOMMU as IRQ managed. This avoids both warnings.

2024-02-09iommu/amd: Introduce per-device domain ID to fix potential TLB aliasing issueVasant Hegde
With v1 page table, the AMD IOMMU spec states that the hardware must use the domain ID to tag its internal translation caches. I/O devices with different v1 page tables must be given different domain IDs. I/O devices that share the same v1 page table __may__ be given the same domain ID. This domain ID management policy is currently implemented by the AMD IOMMU driver. In this case, only the domain ID is needed when issuing the INVALIDATE_IOMMU_PAGES command to invalidate the IOMMU translation cache (TLB). With v2 page table, the hardware uses domain ID and PASID as parameters to tag and issue the INVALIDATE_IOMMU_PAGES command. Since the GCR3 table is setup per-device, and there is no guarantee for PASID to be unique across multiple devices. The same PASID for different devices could have different v2 page tables. In such case, if multiple devices share the same domain ID, IOMMU translation cache for these devices would be polluted due to TLB aliasing. Hence, avoid the TLB aliasing issue with v2 page table by allocating unique domain ID for each device even when multiple devices are sharing the same v1 page table. Please note that this fix would result in multiple INVALIDATE_IOMMU_PAGES commands (one per domain id) when unmapping a translation. Domain ID can be shared until device starts using PASID. We will enhance this code later where we will allocate per device domain ID only when its needed.

2024-02-09iommu/amd: Introduce per-device GCR3 tableSuravee Suthikulpanit
AMD IOMMU GCR3 table is indexed by PASID. Each entry stores guest CR3 register value, which is an address to the root of guest IO page table. The GCR3 table can be programmed per-device. However, Linux AMD IOMMU driver currently managing the table on a per-domain basis. PASID is a device feature. When SVA is enabled it will bind PASID to device, not domain. Hence it makes sense to have per device GCR3 table. Introduce struct iommu_dev_data.gcr3_tbl_info to keep track of GCR3 table configuration. This will eventually replaces gcr3 related variables in protection_domain structure.

2024-02-09iommu/amd: Enable Guest Translation before registering devicesVasant Hegde
IOMMU Guest Translation (GT) feature needs to be enabled before invalidating guest translations (CMD_INV_IOMMU_PAGES with GN=1). Currently GT feature is enabled after setting up interrupt handler. So far it was fine as we were not invalidating guest page table before this point. Upcoming series will introduce per device GCR3 table and it will invalidate guest pages after configuring. Hence move GT feature enablement to early_enable_iommu().

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing and eventfs fixes from Steven Rostedt: - Fix the return code for ring_buffer_poll_wait() It was returing a -EINVAL instead of EPOLLERR. - Zero out the tracefs_inode so that all fields are initialized. The ti->private could have had stale data, but instead of just initializing it to NULL, clear out the entire structure when it is allocated. - Fix a crash in timerlat The hrtimer was initialized at read and not open, but is canceled at close. If the file was opened and never read the close will pass a NULL pointer to hrtime_cancel(). - Rewrite of eventfs. Linus wrote a patch series to remove the dentry references in the eventfs_inode and to use ref counting and more of proper VFS interfaces to make it work. - Add warning to put_ei() if ei is not set to free. That means something is about to free it when it shouldn't. - Restructure the eventfs_inode to make it more compact, and remove the unused llist field. - Remove the fsnotify*() funtions for when the inodes were being created in the lookup code. It doesn't make sense to notify about creation just because something is being looked up. - The inode hard link count was not accurate. It was being updated when a file was looked up. The inodes of directories were updating their parent inode hard link count every time the inode was created. That means if memory reclaim cleaned a stale directory inode and the inode was lookup up again, it would increment the parent inode again as well. Al Viro said to just have all eventfs directories have a hard link count of 1. That tells user space not to trust it. * tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Keep all directory links at 1 eventfs: Remove fsnotify*() functions from lookup() eventfs: Restructure eventfs_inode structure to be more condensed eventfs: Warn if an eventfs_inode is freed without is_freed being set tracing/timerlat: Move hrtimer_init to timerlat_fd open() eventfs: Get rid of dentry pointers without refcounts eventfs: Clean up dentry ops and add revalidate function eventfs: Remove unused d_parent pointer field tracefs: dentry lookup crapectomy tracefs: Avoid using the ei->dentry pointer unnecessarily eventfs: Initialize the tracefs inode properly tracefs: Zero out the tracefs_inode when allocating it ring-buffer: Clean ring_buffer_poll_wait() error return

2024-02-02Input: i8042 - add Fujitsu Lifebook U728 to i8042 quirk tableSzilard Fabian
Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.
