Subject: [dpdk-users] QAT PMD in multi-process mode
Date: Thu, 24 Oct 2019 16:12:05 +0000 [thread overview]
Message-ID: <168A68C163D584429EF02A476D52744268BDF6B3@FMSMSX108.amr.corp.intel.com> (raw)
Hi -
In multi-process model, if same QAT VF is shared between two processes which are spawned from separate executables, primary process give segfault while accessing QAT functions.
It looks like PMD installs access functions in shared area so when secondary process changes those function pointers, they are no longer valid in primary process.
Is QAT PMD going to modified to support this mode in future?
Regards
Pravin
