Maybe it could be moved up after 05/12? Yes, sort of: It's related to GEN4 because the GAS access MRPC command is introduced in GEN4. So it won't really have any effect until after the GEN4 IDs are added. But there is no harm in applying it earlier. > I speculatively reordered the permission check patch and applied these > to my pci/switchtec branch for v5.6 (reverse order from "git log"): > > b96abab6314f ("PCI/switchtec: Add permission check for the GAS access MRPC commands") > 5f23367bd4df ("PCI/switchtec: Move check event ID from mask_event() to switchtec_event_isr()") > 6722d609bc82 ("PCI/switchtec: Remove redundant valid PFF number count") > 3f3a521ecc81 ("PCI/switchtec: Add support for intercom notify and UEC Port") > 9375646b4cf0 ("PCI/switchtec: Fix vep_vector_number ioread width") > aa82130a22f7 ("PCI/switchtec: Use dma_set_mask_and_coherent()") > > If you rework any of the subsequent ones, you can just post those > without reposting these first six. Sounds good, thanks! Logan
