2621704 |
Description: Fixed the resource number size (a 64 bit number) to avoid a scenario where it overwrote it with a 32 bit number and erased the high bits when de-allocating the resource number. In this scenario, when two resource numbers had identical low 32 bits, and because the high bits were cleared, it resulted in the same idx. Consequently, when two idxes were identical, then it freed the same idx twice. |

2093381 |
Description: Modified the calculation of NUM_VF_MSIX to take into account NVME, Virtio Net/Blk, HotPlug PFs & VFs. Since max_total_msix is the maximum number used for all PFs and VFs (Port, NVME. Virtio Net/Blk, HotPlug), if there are not enough MSIX for all the devices, the number of port VF MSIX may be lowered (less than NUM_VF_MSIX) in order to not exceed the max_total_msix. Note: In case of compatibility issues with ab old driver requiring more than 4 MSI-X, you should consider lowering number of PFs/VFs on any of the configurable functions (NVME. Virtio Net/Blk). |
