From: Shijith Thotton Date: Mon, 30 Aug 2021 16:14:46 +0000 (+0530) Subject: event/cnxk: fix max timer chunk pool cache size X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=08d681e9c4a0efbef19167716029f54b9c960134;p=dpdk.git event/cnxk: fix max timer chunk pool cache size Reduced max chunk pool cache size from RTE_MEMPOOL_CACHE_MAX_SIZE(512) to 128. If chunk pool cache is empty, it gets filled during arm. Filling 512 entries at a time will fail arm if timeout is shorter, hence reduce the pool cache size.
