[Bug 2074380] Re: [UBUNTU 22.04] kernel: s390/cpum_cf: make crypto counters upward compatible
The commit applies fine to the noble master-next tree (kernel 6.8), and a test build was triggered here: https://launchpad.net/~fheimes/+archive/ubuntu/lp2074380 However, the cpumf code in jammy master-next (kernel 5.15) is quite different. git blame tells me that probably the following commits are needed as well: 111783-1a33aee1dc24 s390/cpum_cf: remove function validate_ctr_auth() by inline code 111784-9ae9b868aeaa s390/cpum_cf: provide counter number to validate_ctr_version() 111785:46c4d945ea1f s390/cpum_cf: introduce static CPU counter facility information but they (first of all 46c4d945ea1f) also do not apply cleanly.

[Bug 2071471] Re: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads
Many thanks for confirming, Niklas! ** Description changed: SRU Justification: [Impact] * With the introduction of c76c067e488c "s390/pci: Use dma-iommu layer" (upstream with since kernel v6.7-rc1) there was a move (on s390x only) to a different dma-iommu implementation. * And with 92bce97f0c34 "s390/pci: Fix reset of IOMMU software counters" (again upstream since 6.7(rc-1) the IOMMU_DEFAULT_DMA_LAZY kernel config option should now be set to 'yes' by default for s390x. * Since CONFIG_IOMMU_DEFAULT_DMA_STRICT and IOMMU_DEFAULT_DMA_LAZY are related to each other CONFIG_IOMMU_DEFAULT_DMA_STRICT needs to be set to "no" by default, which was upstream done by b2b97a62f055 "Revert "s390: update defconfigs"". * These changes are all upstream, but were not picked up by the Ubuntu kernel config. * And not having these config options set properly is causing significant PCI-related network throughput degradation (up to -72%). * This shows for almost all workloads and numbers of connections, deteriorating with the number of connections increasing. * Especially drastic is the drop for a high number of parallel connections (50 and 250) and for small and medium-size transactional workloads. However, also for streaming-type workloads the degradation is clearly visible (up to 48% degradation). [Fix] * The (upstream accepted) fix is to set IOMMU_DEFAULT_DMA_STRICT=no and IOMMU_DEFAULT_DMA_LAZY=y (which is needed for the changed DAM IOMMU implementation since v6.7). [Test Case] - * Setup two Ubuntu Server 24.04 LPARs (with kernel 6.8) + * Setup two Ubuntu Server 24.04 systems (with kernel 6.8) (one acting as server and as client) that have (PCIe attached) RoCE Express devices attached and that are connected to each other. + + * Verify if the the iommu_group type of the used PCI device is DMA-FQ: +cat /sys/bus/pci/devices/\:00\:00.0/iommu_group/type +DMA-FQ * Sample workload rr1c-200x1000-250 with rr1c-200x1000-250.xml: * Install uperf on both systems, client and server. * Start uperf at server: uperf -s * Start uperf at client: uperf -vai 5 -m uperf-profile.xml * Switch from strict to lazy mode either using the new kernel (or the test build below) or using kernel cmd-line parameter iommu.strict=0. * Restart uperf on server and client, like before. * Verification will be performed by IBM. [Regression Potential] * The is a certain regression potential, since the behavior with the two modified kernel config options will change significantly. * This may solve the (network) throughput issue with PCI devices, but may also come with side-effects on other PCIe based devices (the old compression adapters or the new NVMe carrier cards). [Other] * CCW devices are not affected. * This is s390x-specific only, hence will not affect any other architecture. __ Symptom: Comparing Ubuntu 24.04 (kernelversion: 6.8.0-31-generic) against Ubuntu 22.04, all of our PCI-related network measurements on LPAR show massive throughput degradations (up to -72%). This shows for almost all workloads and numbers of connections, detereorating with the number of connections increasing. Especially drastic is the drop for a high number of parallel connections (50 and 250) and for small and medium-size transactional workloads. However, also for streaming-type workloads the degradation is clearly visible (up to 48% degradation). Problem: With kernel config setting CONFIG_IOMMU_DEFAULT_DMA_STRICT=y, IOMMU DMA mode changed from lazy to strict, causing these massive degradations. Behavior can also be changed with a kernel commandline parameter (iommu.strict) for easy verification. The issue is known and was quickly fixed upstream in December 2023, after being present for little less than two weeks. Upstream fix: https://github.com/torvalds/linux/commit/b2b97a62f055dd638f7f02087331a8380d8f139a Repro: rr1c-200x1000-250 with rr1c-200x1000-250.xml: 0) Install uperf on both systems, client and server. 1) Start uperf at server: uperf -s 2) Start uperf at client: uperf -vai 5 -m uperf-profile.xml 3) Switch from strict to lazy mode using kernel commandline parameter iommu.strict=0.
[Bug 2071471] Re: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads
Well, 'make defconfig' is what I cannot use, since we have the Ubuntu specific kernel options (and tools). But since "not set" defaults to no, I guess it should be okay to explicitly set CONFIG_IOMMU_DEFAULT_DMA_STRICT=n. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2071471 Title: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/2071471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looks like it's not sufficient to have IOMMU_DEFAULT_DMA_LAZY=y only in addition IOMMU_DEFAULT_DMA_STRICT=n seems to be needed on top (otherwise the build failed for me). (Which I think is not super great upstream, one option should be fine -- with the two kernel options, there are now two unspecific cases: both n and both y - anyway ...)

[Bug 2071471] Re: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads
Hi Niklas, thanks for the backgrounds. So to sum it up: The Ubuntu kernel config options for IOMMU_DEFAULT_DMA_LAZY and IOMMU_DEFAULT_DMA_STRICT haven't changed since jammy/22.04: 5.15.0-1.1 to 5.15.0-115.125 CONFIG_IOMMU_DEFAULT_DMA_STRICT=y # CONFIG_IOMMU_DEFAULT_DMA_LAZY is not set 6.8.0-6.6 to 6.8.0-38.38 CONFIG_IOMMU_DEFAULT_DMA_STRICT=y # CONFIG_IOMMU_DEFAULT_DMA_LAZY is not set But with the introduction of c76c067e488c s390/pci: Use dma-iommu layer which moves to a different dma-iommu implementation and 92bce97f0c34 s390/pci: Fix reset of IOMMU software counters (both available since 6.7(rc-1) the IOMMU_DEFAULT_DMA_LAZY kernel config option should be set to 'yes' by default for s390x. Does CONFIG_IOMMU_DEFAULT_DMA_STRICT need to be set to No on top? I don't think so - if lazy is 'yes'. So I believe we can go with 'IOMMU_DEFAULT_DMA_LAZY=y' for s390x only and should be good again. I assume that such situations happen not very often, so it would be ideal if IBM could give us a quick heads-up in such cases (where a kernel config default value for s390x is changed upstream), so that we can double check and potentially take over changes into the Ubuntu config by hand. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2071471 Title: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/2071471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello and thanks for having reported this issue. Once the patch set 'Fix doorbell emulation for v2 API on PPC' with patches: - arch/powerpc/kvm: Add DPDES support in helper library for Guest state buffer - arch/powerpc/kvm: Fix doorbell emulation for v2 API are upstream accepted (having them in 'linux-next' is sufficient), we can think about picking them.
