------- Comment From niklas.schne...@ibm.com 2020-04-21 09:45 EDT------- With the introduction of CPU directed interrupts the kernel parameter pci=force_floating was introduced to fall back to the previous behavior using floating irqs. Furthermore this fallback is used on machines lacking support for directed interrupts.
However we were still setting the affinity in that case, both in __irq_alloc_descs() and via the irq_set_affinity callback in struct irq_chip. -- 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/1874062 Title: [UBUNTU 20.04] Performance floating interrupt Status in linux package in Ubuntu: New Bug description: Description will follow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874062/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
