** Description changed: SRU Justification [Impact] - * Microsoft requested patches to better spread IRQs per cpu + * Microsoft requested MANA patches for the following: + * Better spread IRQs per cpu + * Represent packets transmitted after GSO processing + * Allocate MSI-X vectors in PCI dynamically + * Support holes in device list reply msg [Fix] - * 3 clean cherry-picks from upstream - * c1f5204efcbc: "cpumask: add cpumask_weight_andnot()" - * dcee228078c3: "cpumask: define cleanup function for cpumasks" - * 91bfe210e196: "net: mana: add a function to spread IRQs per CPUs" + * Plucky: + * 5 clean cherry-picks from linux-next + * abff71a: "net: mana: Set tx_packets to post gso processing packet count" + * 0792c36: "PCI/MSI: Export pci_msix_prepare_desc() for dynamic MSI-X allocations" + * aaf2d66: "PCI: hv: Allow dynamic MSI-X vector allocation" + * 52e3cfc: "net: mana: explain irq_setup() algorithm" + * 453d635: "net: mana: Allow irq_setup() to skip cpus for affinity" + * 1 backport from linux-next + * 20542d9: "net: mana: Allocate MSI-X vectors dynamically" + * Noble: + * 5 clean cherry-picks from upstream + * e6160dc: "cpumask: add cpumask_weight_andnot()" + * add3803: "cpumask: define cleanup function for cpumasks" + * fb37331: "net: mana: add a function to spread IRQs per CPUs" + * 6b7d4e6: "net: mana: Assigning IRQ affinity on HT cores" + * 4d85b5e: "net: mana: Support holes in device list reply msg" + * 5 clean cherry-picks from linux-next + * abff71a: "net: mana: Set tx_packets to post gso processing packet count" + * 0792c36: "PCI/MSI: Export pci_msix_prepare_desc() for dynamic MSI-X allocations" + * aaf2d66: "PCI: hv: Allow dynamic MSI-X vector allocation" + * 52e3cfc: "net: mana: explain irq_setup() algorithm" + * 453d635: "net: mana: Allow irq_setup() to skip cpus for affinity" + * 1 backport from linux-next + * 20542d9: "net: mana: Allocate MSI-X vectors dynamically" [Test Plan] * Compile tested + * Microsoft to test further [Regression potential] - * Changes are largely localized to MANA and have been upstream as of - 6.9. Possible regressions could result in unexpected workflow in which - performance degradation occurs due to updated IRQ spreading heuristic. + * Changes are largely localized to MANA and Hyper-V, and either already + upstream or queued for upstream in the next merge window. Possible + regressions could result in unexpected behavior of MANA driver. [Other info] * SF#00413058 + * SF#00413245 + * SF#00413050 + * SF#00413047
