No changes to the driver were required with the new version of the hardware. [logang: rewrote commit message] Signed-off-by: Ben Reed Signed-off-by: Logan Gunthorpe Signed-off-by: Bjorn Helgaas Link: https://patch.msgid.link/20260505161633.67454-1-logang@deltatee.com Signed-off-by: Sasha Levin --- LLM Generated explanations, may be completely bogus: The background history search finished. In this 6.18.43 checkout, `git log -S 'SWITCHTEC_GEN5'` and `git log --grep='switchtec: Add'` didn’t turn up individual Switchtec ID commits — only the bulk merge `5d324e5159d9e` and unrelated history. That matches what we already saw: Gen3/4/5 support is present, but this tree doesn’t have granular Switchtec commit history. That doesn’t change the backport assessment: this is a standard PCI device ID addition for an existing driver, it fits the stable “just add a device ID” rule, and it should apply cleanly to 6.18.43. **YES** drivers/pci/switch/switchtec.c | 16 ++++++++++++++++ include/linux/switchtec.h | 1 + 2 files changed, 17 insertions(+) diff --git a/drivers/pci/switch/switchtec.c b/drivers/pci/switch/switchtec.c index 5ff84fb8fb0f4..f32ddfa79da99 100644 --- a/drivers/pci/switch/switchtec.c +++ b/drivers/pci/switch/switchtec.c @@ -1852,6 +1852,22 @@ static const struct pci_device_id switchtec_pci_tbl[] = { SWITCHTEC_PCI_DEVICE(0x5552, SWITCHTEC_GEN5), /* PAXA 52XG5 */ SWITCHTEC_PCI_DEVICE(0x5536, SWITCHTEC_GEN5), /* PAXA 36XG5 */ SWITCHTEC_PCI_DEVICE(0x5528, SWITCHTEC_GEN5), /* PAXA 28XG5 */ + SWITCHTEC_PCI_DEVICE(0x6048, SWITCHTEC_GEN6), /* PFXs 48XG6 */ + SWITCHTEC_PCI_DEVICE(0x6064, SWITCHTEC_GEN6), /* PFXs 64XG6 */ + SWITCHTEC_PCI_DEVICE(0x6044, SWITCHTEC_GEN6), /* PFXs 144XG6 */ + SWITCHTEC_PCI_DEVICE(0x6060, SWITCHTEC_GEN6), /* PFXs 160XG6 */ + SWITCHTEC_PCI_DEVICE(0x6148, SWITCHTEC_GEN6), /* PSXs 48XG6 */ + SWITCHTEC_PCI_DEVICE(0x6164, SWITCHTEC_GEN6), /* PSXs 64XG6 */ + SWITCHTEC_PCI_DEVICE(0x6144, SWITCHTEC_GEN6), /* PSXs 144XG6 */ + SWITCHTEC_PCI_DEVICE(0x6160, SWITCHTEC_GEN6), /* PSXs 160XG6 */ + SWITCHTEC_PCI_DEVICE(0x6248, SWITCHTEC_GEN6), /* PFX 48XG6 */ + SWITCHTEC_PCI_DEVICE(0x6264, SWITCHTEC_GEN6), /* PFX 64XG6 */ + SWITCHTEC_PCI_DEVICE(0x6244, SWITCHTEC_GEN6), /* PFX 144XG6 */ + SWITCHTEC_PCI_DEVICE(0x6260, SWITCHTEC_GEN6), /* PFX 160XG6 */ + SWITCHTEC_PCI_DEVICE(0x6348, SWITCHTEC_GEN6), /* PSX 48XG6 */ + SWITCHTEC_PCI_DEVICE(0x6364, SWITCHTEC_GEN6), /* PSX 64XG6 */ + SWITCHTEC_PCI_DEVICE(0x6344, SWITCHTEC_GEN6), /* PSX 144XG6 */ + SWITCHTEC_PCI_DEVICE(0x6360, SWITCHTEC_GEN6), /* PSX 160XG6 */ SWITCHTEC_PCI100X_DEVICE(0x1001, SWITCHTEC_GEN4), /* PCI1001 16XG4 */ SWITCHTEC_PCI100X_DEVICE(0x1002, SWITCHTEC_GEN4), /* PCI1002 12XG4 */ SWITCHTEC_PCI100X_DEVICE(0x1003, SWITCHTEC_GEN4), /* PCI1003 16XG4 */ diff --git a/include/linux/switchtec.h b/include/linux/switchtec.h index cdb58d61c1526..724da6c08bf7d 100644 --- a/include/linux/switchtec.h +++ b/include/linux/switchtec.h @@ -42,6 +42,7 @@ enum switchtec_gen { SWITCHTEC_GEN3, SWITCHTEC_GEN4, SWITCHTEC_GEN5, + SWITCHTEC_GEN6, }; struct mrpc_regs { -- 2.53.0
