Jeff, We have a few more patches required to bring out driver up to date with upstream. Looks like there's 1 additional kernel patch we'll need you to integrate before getting us a pointer to a kernel we can then apply our lpfc driver patches to. See the additional patches we need to bring us up to date since we first filed this bug.
thx Laurie Here is the list of additional patch commit ids that would be used to update from 12.6.0.2 (end of list in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1855303) to 12.6.0.3 and 12.6.0.4 and to add FPIN/mpio support: scsi: lpfc: Fix incomplete NVME discovery when target commit 3ec5ec408ca633e17d3483e8b806c9fa447e19cc scsi: lpfc: Fix: Rework setting of fdmi symbolic node name registration commit d4e9ddd5ae8f26c521692283c7cbedc7e9881529 scsi: lpfc: Fix missing check for CSF in Write Object Mbox Rsp commit a0c94c5ef874b214305cca965acc7edc27bb69a6 scsi: lpfc: Fix Fabric hostname registration if system hostname changes commit 3712967ea7f2d3793ae2a39e9eae2df111d770b5 scsi: lpfc: Fix ras_log via debugfs commit 25d4132f95c25e6f78a94666a1e067291272888a scsi: lpfc: Fix disablement of FC-AL on lpe35000 models commit 265fb8efca11eee1ffe8edd2bc0a9fbf31b6b84e scsi: lpfc: Fix unmap of dpp bars affecting next driver load commit b88d705fa037b222ecdd5de867132ae25403fe48 scsi: lpfc: Fix MDS Latency Diagnostics Err-drop rates commit 78a7872570fbeed44e7362354619b403c6e6de1e scsi: lpfc: Fix improper flag check for IO type commit f44ccecf36581a2030313e979127013f9d455d3a scsi: lpfc: Update lpfc version to 12.6.0.3 commit e627554eedcfac83bb2ba073adf711a13049273a ---- scsi: lpfc: Fix RQ buffer leakage when no IOCBs available commit 9c75a0dee87b2bad80d381ad9fa8ef90847d3a1d scsi: lpfc: Fix lpfc_io_buf resource leak in lpfc_get_scsi_buf_s4 error path commit 89cc9dba63c91a6c796dc46342c1d57c82c9b0cd scsi: lpfc: Fix broken Credit Recovery after driver load commit 692fc8380ca0f9185e75e01a74357d2cf3083743 scsi: lpfc: Fix registration of ELS type support in fdmi commit 0f74f70cb674e3b8712e896863ad85db4d193d46 scsi: lpfc: Fix release of hwq to clear the eq relationship commit 01034e708a353fed29963d084c35d58785a317a6 scsi: lpfc: Fix compiler warning on frame size commit 3cd50eac891db354e945bf9898726e163a19560e scsi: lpfc: Fix coverity errors in fmdi attribute handling commit 3ad04f4f0ad75ad4e7d886133f673d9fe20aa9c4 scsi: lpfc: Remove handler for obsolete ELS - Read Port Status (RPS) commit 8d9fae72109e9921f52be342007b4c78490ea4fe scsi: lpfc: Clean up hba max_lun_queue_depth checks commit 20d674a4bf64acf54eadc7215ea32b88a3a7687e scsi: lpfc: Update lpfc version to 12.6.0.4 commit 35817310d9e05e666dbd242750008dad33ed8992 scsi: lpfc: Copyright updates for 12.6.0.4 patches commit fd6cc30f341fea14bac45bf1c5c9d10702c18a9d --- This is the one we need you to add --> scsi: fc: Update Descriptor definition and add RDF and Link Integrity FPINs commit 73ec6d2748dc35db2b32cf3c182a27c4a0837b9b scsi: lpfc: add RDF registration and Link Integrity FPIN logging commit df3fe76658ed47617741819a501e2bd2ae446962 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1858840 Title: Vport creation leads to out of memory and server hung on Ubuntu 18.04.3 (5.0) on Broadcom FC HBAs Status in linux package in Ubuntu: Invalid Bug description: Jeff, We have analyzed this issue and see that there are 3 missing patches required to fix this problem.
