[PATCH net-next 00/22] Add support for Chelsio T5 adapter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

This patch series adds support for Chelsio's T5 adapter. It also adds support
for new features of T5. It adds these in cxgb4, cxgb4vf, RDMA/cxgb4 and
csiostor drivers.

Chelsio's T5 asic moves the architecture into 40GbE speeds. T5 is a 10/40GbE
controller with full offload support of a complete Unified Wire solution
comprising NIC, Virtualization, TOE, iWARP RDMA and FCoE.

T5 supports all the offload, virtualization and switching capabilities of the
existing T4 and adds some new features. The patch series does basic
intialization for T5 in each driver. The patch series implements a low
latency Write Combining work request path in cxgb4 and RDMA/cxgb4 driver for
T5. It supports new T5 feature DSGL in RDMA/cxgb4 driver which enables direct
DMA by HW to memory region PBL arrays and fast register PBL arrays from host
memory. It adds support for dumping T5 registers, T5's debugfs support and
enables doorbell drop recovery only for T4 in cxgb4 driver.

To facilitate addition of support in csiostor for future adapters, a new
framework for adapter specific operations has been defined. Consequently, T4
and T5 specific operations are now separated into different files. One of the
csiostor patches also includes common bug fixes.

We are submitting changes in all the drivers for T5 in one series since there
are common changes in cxgb4 driver which are required by all the ULDs and
csiostor. This way we can avoid build failures, build dependencies and ensure
smooth integration.

We request to merge this patch series via David Miller's net-next tree. We are
copying respective maintainers of all the drivers for reviewing the changes.
Kindly let us know in case of any review comments.

We have successfully carried out networking, virtualization, iWARP and storage
related stress tests on this patch series.

Thanks,
Vipul Pandya
