| Summary | 0000673: [AlmaLinux][MANA][Backport][Distros] Avoid DMA queue allocation failure under memory fragmentation | ||||
| Description | Request backport of the following patches. Summary The MANA driver can fail to bring up its queues on systems with high memory utilization because every GDMA queue ring is allocated as a single dma_alloc_coherent() of the whole power-of-2 ring size. Under memory fragmentation these high-order allocations may fail, preventing the driver from creating queues when opening the interface, after a VF reset, or when reconfiguring channels, ring parameters or MTU.
