Subject: [dpdk-dev] [PATCH v2 0/2] compress/qat: im buffer too small - split op
Date: Wed, 8 Apr 2020 14:50:59 +0200 [thread overview]
Message-ID: <20200408125101.25764-1-adamx.dybkowski@intel.com> (raw)
This patch implements a special way of buffer handling when internal
QAT IM buffer is too small for Huffman dynamic compression operation.
Instead of falling back to fixed compression, the operation is now
split into multiple smaller dynamic compression requests (possible to
execute on QAT) and their results are then combined and copied into
the output buffer. This is not possible if any checksum calculation
was requested - in such case the code falls back to fixed compression
as before.
v2:
* various post-review small fixes
