Subject: [PATCH v2 00/18] can: m_can: Optimizations for m_can/tcan part 2
Date: Wed, 25 Jan 2023 20:50:41 +0100 [thread overview]
Message-ID: <20230125195059.630377-1-msp@baylibre.com> (raw)
Hi Marc and everyone,
second version part 2, I fixed the bug I noticed for integrated m_can
devices. The accounting was wrong or missing for these. I don't have the
integrated hardware myself so any testing is appreciated (I only have
the tcan device to test the mcan driver). Also v2 rebases on top of
v6.2-rc5.
The series implements many small and bigger throughput improvements and
adds rx/tx coalescing at the end.
Best,
Markus
Changes in v2:
- Rebased on v6.2-rc5
- Fixed missing/broken accounting for non peripheral m_can devices.
