The fix / replacement for that is too large to squeeze in at this late date.

PCI/IDE: Fix reading a wrong reg for unused sel stream initialization

2026-01-23T01:47:21Z

During pci_ide_init(), it will write PCI_ID_RESERVED_STREAM_ID into all unused selective IDE stream blocks. In a selective IDE stream block, IDE stream ID field is in selective IDE stream control register instead of selective IDE stream capability register.

PCI/IDE: Fix off by one error calculating VF RID range

2026-01-23T01:47:21Z

The VF ID range of an SR-IOV device is [0, num_VFs - 1]. pci_ide_stream_alloc() mistakenly uses num_VFs to represent the last ID. Fix that off by one error to stay in bounds of the range.

Revert "PCI/TSM: Report active IDE streams"

2026-01-23T01:46:44Z

The proposed ABI failed to account for multiple host bridges with the same stream name. The fix needs to namespace streams or otherwise link back to the host bridge, but a change like that is too big for a fix. Given this ABI never saw a released kernel, delete it for now and bring it back later with this issue addressed.

PCI: Fix Resizable BAR restore order

2026-01-22T16:29:55Z

The commit 337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback path") changed BAR resize to layer rebar code and resource setup/restore code cleanly. Unfortunately, it did not consider how the value of the BAR Size field impacts the read-only bits in the Base Address Register (PCIe7 spec, sec. 7.8.6.3). That is, it very much matters in which order the BAR Size and Base Address Register are restored. Post-337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback path") during BAR resize rollback, pci_do_resource_release_and_resize() attempts to restore the old address to the BAR that was resized, but it can fail to setup the address correctly if the address has low bits set that collide with the bits that are still read-only. As a result, kernel's resource and BAR will be out-of-sync. Fix this by restoring BAR Size before rolling back the resource changes and restoring the BAR.

PCI: Fix BAR resize rollback path overwriting ret

2026-01-22T16:28:59Z

The commit 337b1b566db0 ("PCI: Fix restoring BARs on BAR resize rollback path") added BAR rollback to pci_do_resource_release_and_resize() in case of resize failure. On the rollback, pci_claim_resource() is called, which can fail and the code is prepared for that possibility. pci_claim_resource()'s return value, however, overwrites the original value of ret so pci_do_resource_release_and_resize() will return an incorrect value in the end (as pci_claim_resource() normally succeeds, in practice ret will be 0). Fix the issue by directly calling pci_claim_resource() inside the if ().
