The following packages have been released to the elrepo repository: src: kmod-moxa-mxupcie-4.1-2.el8.elrepo.src.rpm x86_64: kmod-moxa-mxupcie-4.1-2.el8.elrepo.x86_64.rpm kmod-moxa-mxupcie-tools-4.1-2.el8.elrepo.x86_64.rpm Minor adjustments were made to the spec file to match the current template file which includes a bug fix. The packages were built with the secureboot key and signed for publication. Thank you for the contribution. |

Quoting a note from @oden on our IRC: kmod-moxa-mxupcie isn't needed in RHEL 9 as the driver was added and enabled per default in RHEL 9. There's a RFE for the RHEL 8 kernel to enable it there. It was a mess. The driver was added upstream in the v4.x kernel but changed name in the v5.x kernel. So, RHEL 8 has the driver but not built. RHEL 9 has the driver built and enabled. |

Needed to reopen in order to comment here. It seems the package is obsolete in RHEL 8 as well. Initial tests shows the devices are recognized, but you need to add "8250.nr_uarts=XX" (XX = 2(?) + actual number of ports in the moxa card) when booting it (in /etc/default/grub) * Wed Jul 20 2022 Jarod Wilson <jarod@redhat.com> [4.18.0-411.el8] [...] - serial: 8250_pci: rewrite pericom_do_set_divisor() (Myron Stowe) [2096364] - serial: 8250_pci: Fix ACCES entries in pci_serial_quirks array (Myron Stowe) [2096364] - serial: 8250_pci: Merge 8250_moxa to 8250_pci (Myron Stowe) [2096364] - serial: 8250: Use dev_get_drvdata where possible (Myron Stowe) [2096364] - serial: 8250: pericom_do_set_divisor can be static (Myron Stowe) [2096364] - serial: 8250: Add support for higher baud rates to Pericom chips (Myron Stowe) [2096364] - serial: 8250_pci: Have ACCES cards that use the four port Pericom PI7C9X7954 chip use the pci_pericom_setup() (Myron Stowe) [2096364] - serial: 8250_pci: Fix number of ports for ACCES serial cards (Myron Stowe) [2096364] - serial: 8250_pci: Replace custom code with pci_match_id() (Myron Stowe) [2096364] [...] The Intel patch that broke the kernel in 2020 is also fixed with this RHEL 8 kernel. (needed "pci=noioapicquirk") See: https://access.redhat.com/solutions/6155782 https://lore.kernel.org/lkml/b2da25c8-121a-b241-c028-68e49bab0081@tik.uni-stuttgart.de/ Cheers. |
