Bug ID: 1871
Summary: idxd_dmadev.portal volatile usage
Product: DPDK
Version: 21.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
idxd_dmadev_probe_pci uses RTE_PTR_ADD(idxd.u.pci->portals) [1] where the
argument is volatile [2] and assigns the result to idxd_dmadev.portal which is
not volatile [3]. Disqualifying quantifiers should be done explicitly if
desired (not implicitly through RTE_PTR_ADD) and clear comments added, or
qualifiers should be preserved.
