[Kernel-packages] [Bug 1971699] Re: disable Intel DMA remapping by default
This bug is awaiting verification that the linux-xilinx- zynqmp/5.15.0-1029.33 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-done-jammy-linux-xilinx-zynqmp'. If the problem still exists, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-failed-jammy-linux-xilinx-zynqmp'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Kernel-packages] [Bug 1971699] Re: disable Intel DMA remapping by default
A user has reported extensive performance issues with a Lenovo Thinkpad X1 Extreme Gen 2 laptop computer, in bug 1973434. The user reports video playback hangs, browser hangs and virtual machines hanging. Their dmesg indicates the system has 2x IOMMUs and there are 25 groups being configured. They tested "intel_iommu=off", and the performance issues are no longer seen. -- 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/1971699 Title: disable Intel DMA remapping by default Status in linux package in Ubuntu: Invalid Status in linux source package in Jammy: In Progress Bug description: [Impact] It seems that enabling Intel IOMMU can cause some weird gfx problems, see for example: https://bugs.launchpad.net/bugs/1971146 https://bugs.launchpad.net/bugs/1965882 [Test case] We don't have any specific test case, only other bug reports that tracked down the origin of the issue as being introduced when CONFIG_INTEL_IOMMU_DEFAULT_ON has been enabled by default.

[Kernel-packages] [Bug 1971699] Re: disable Intel DMA remapping by default
A user has ran into a storage performance issue, and it has been traced back to CONFIG_INTEL_IOMMU_DEFAULT_ON being enabled. They have a Dell XtremIO FC storage server, running VMWare ESXi 7.0U3, with 4x pvscsi controllers (2 LUNs per controller), running a single large LV with 8-way 1MB stripe. There are Ubuntu 20.04 and 22.04 VMs running on the same server. The VMs are attached to the storage unit through iSCSI. When running the following FIO script: [write1] filename=/dev/xio2data/prd01 readwrite=randwrite random_generator=tausworthe64 blocksize=8K ioengine=libaio iodepth=32 direct=1 runtime=30 numjobs=8 group_reporting invalidate=0 On 20.04 with 5.4.0-109-generic they see: WRITE: bw=1010MiB/s (1059MB/s), 1010MiB/s-1010MiB/s (1059MB/s-1059MB/s), io=29.6GiB (31.8GB), run=30007-30007msec They note a 2%-3% %SYS load. On 22.04 with 5.15.0-27-generic they see: WRITE: bw=568MiB/s (595MB/s), 568MiB/s-568MiB/s (595MB/s-595MB/s), io=16.6GiB (17.9GB), run=30007-30007msec They note a consistent 18%-19% %SYS load, and poor performance. It seems VMWare emulates a IOMMU, and their VMs were configuring 8 IOMMU groups for their PCI devices, and it was significantly impacting iSCSI performance. When intel_iommu=off was supplied on the kernel command line, the performance issue is no longer present. This is a suitable workaround for the time being. This user is in agreement with and asking for CONFIG_INTEL_IOMMU_DEFAULT_ON to be disabled. -- 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/1971699 Title: disable Intel DMA remapping by default Status in linux package in Ubuntu: Invalid Status in linux source package in Jammy: In Progress Bug description: [Impact] It seems that enabling Intel IOMMU can cause some weird gfx problems, see for example: https://bugs.launchpad.net/bugs/1971146 https://bugs.launchpad.net/bugs/1965882 [Test case] We don't have any specific test case, only other bug reports that tracked down the origin of the issue as being introduced when CONFIG_INTEL_IOMMU_DEFAULT_ON has been enabled by default.
