Hello All, Currently, we are facing an issue with memory allocation failure in memseg_primary_init(). When we configure the CONFIG_RTE_MAX_MEM_MB to 512MB and correspondingly configured the number of huge pages for our platform. But the virtual memory allocation is failing.
It appears that its trying to allocate CONFIG_RTE_MAX_MEMSEG_PER_LIST * Huge page size (i.e. 8192 * 2MB = 0x400000000) and virtual memory allocation is failing. Also tried changing the CONFIG_RTE_MAX_MEMSEG_PER_LIST to 64 with which virtual memory allocation is passing for the 128MB (64 * 2MB). But looks like 128MB memory is not enough and it is causing the PCIe enumeration failure. Not able allocate virtual memory beyond 128MB by increasing the CONFIG_RTE_MAX_MEMSEG_PER_LIST beyond 64. Is there are any settings(argument) which we need to pass as part of rte_eal_init() to get success in the virtual memory allocation? Please advise. Thanks, Kamaraj
