Alex- Here is the public list of PCI IDs for PCH root ports that can utilize the ACS workaround: Ibexpaek PCH - 3b42, 3b43, 3b44, 3b45, 3b46, 3b47, 3b48, 3b49, 3b4a, 3b4b, 3b4c, 3b4d, 3b4e, 3b4f, 3b50, 3b51 Cougarpoint PCH - 1c10, 1c11, 1c12, 1c13, 1c14, 1c15, 1c16, 1c17, 1c18, 1c19, 1c1a, 1c1b, 1c1c, 1c1d, 1c1e, 1c1f, 1e10, 1e11, 1e12, 1e13, 1e14, 1e15, 1e16, 1e17, 1e18, 1e19, 1e1a, 1e1b, 1e1c, 1e1d, 1e1e, 1e1f Lynxpoint-H PCH - 8c10, 8c11, 8c12, 8c13, 8c14, 8c15, 8c16, 8c17, 8c18, 8c19, 8c1a, 8c1b, 8c1c, 8c1d, 8c1e, 8c1f Lynxpoint-LP PCH - 9c10, 9c11, 9c12, 9c13, 9c14, 9c15, 9c16, 9c17, 9c18, 9c19, 9c1a, 9c1b Wildcatpoint PCH - 9c90, 9c91, 9c92, 9c93, 9c94, 9c95, 9c96, 9c97, 9c98, 9c99, 9c9a, 9c9b Note that this is not necessarily an exhaustive list yet, this is just the best I have so far, but it should be sufficient to start with. Don, please review and provide comments or ACK to upstream patch: http://www.spinics.net/lists/linux-pci/msg28473.html Thanks Sorry about that, in my head I had ACK'd your patch, it works better when I actually send the email. Patch(es) available on kernel-3.10.0-107.el7 I've been able to track down the PCI IDs for X79 root ports: 1d10, 1d12, 1d14, 1d16, 1d18, 1d1a, 1d1c, 1d1e Note that these root ports provide the same isolation as the other ports we listed in this BZ 1037684 and the same quirk applies. This request was resolved in Red Hat Enterprise Linux 7.0. Contact your manager or support representative in case you have further questions about the request. |
