Subject: [dpdk-stable] [PATCH v2] pipeline: fix instruction translation for table and mailbox fields
Date: Wed, 24 Mar 2021 11:36:03 +0000 [thread overview]
Message-ID: <20210324113603.56624-1-cristian.dumitrescu@intel.com> (raw)
In-Reply-To: <20210319143625.78445-1-cristian.dumitrescu@intel.com>
The SWX pipeline instructions work with operands of different types:
header fields (h.header.field), packet meta-data (m.field), extern
object mailbox field (e.obj.field), extern function (f.field), action
data read from table entries (t.field), or immediate values; hence the
HMEFTI acronym.
For some pipeline instructions (add/sub, srl/shr, jmplt/jmpgt), only
the H, M and I cases were handled, while the E, F and T cases were
disregarded. This is what we fix here.
Fixes: baf7999303d0 ("pipeline: introduce SWX add instruction")
Fixes: c88c62943818 ("pipeline: introduce SWX subtract instruction")
Fixes: b09ba6d0a3c2 ("pipeline: introduce SWX SHL instruction")
Fixes: e0f51638b715 ("pipeline: introduce SWX SHR instruction")
Fixes: b3947e25bed4 ("pipeline: introduce SWX jump and return instructions")
