Subject: [dpdk-dev] [PATCH] build: fix memory init failures with 32-bit builds
Date: Thu, 2 Jul 2020 11:57:21 +0100 [thread overview]
Message-ID: <20200702105721.1044076-1-bruce.richardson@intel.com> (raw)
When building with meson, the default size of virtual address space
reserved for mapping pages was globally set at 512GB, which is too big for
use in 32-bit processes. To match the behaviour with "make", we configure
this to be 512GB for 64-bit and 2MB for 32-bit builds.
Bugzilla ID: 498
Fixes: 66cc45e293ed ("mem: replace memseg with memseg lists")
