Re: [PATCH v5 net-next 0/7] Support Armada 37xx SoC (ARMv8 64-bits) in mvneta driver

Show all headers | View raw

Hi Gregory,

Checked on a388-gp with and without HWBM, also both ports work on
a3700 (second one after changing to sgmii).

Tested-by: Marcin Wojtas <mw@semihalf.com>

Best regards,
Marcin

> The Armada 37xx is a new ARMv8 SoC from Marvell using same network

>
> - 64-bits support: the first patches allow using the driver on a 64-bit
>   architecture.
>
> - MBUS support: the mbus configuration is different on Armada 37xx
>   from the older SoCs.
>
> - per cpu interrupt: Armada 37xx do not support per cpu interrupt for
>   the NETA IP, the non-per-CPU behavior was added back.
>
> The first patch is an optimization in the rx path in swbm mode.
> The second patch remove unnecessary allocation for HWBM.
> The first item is solved by patches 4 and 5.
> The 2 last items are solved by patch 6.
> In patch 7 the dt support is added.
>
> Beside Armada 37xx, this series have been again tested on Armada XP
> and Armada 38x (with Hardware Buffer Management and with Software
> Buffer Management).
>
> This is the 5th version of the series:
> - 1st version:

>
> - 2nd version:

>
> - 4th version:

>
> Changelog:
> v4 -> v5:
>  - remove unnecessary cast in patch 3
>
> v3 -> v4:
>  - Adding new patch: "net: mvneta: do not allocate buffer in rxq init
>    with HWBM"
>
>  - Simplify the HWBM case in patch 3 as suggested by Marcin
>
> v2 -> v3:
>  - Adding patch 1 "Optimize rx path for small frame"
>
>  - Fix the kbuild error by moving the "phys_addr += pp->rx_offset_correction;"
>   line from patch 2 to patch 3 where rx_offset_correction is introduced.
>
>  - Move the memory allocation of the buf_virt_addr of the rxq to be
>    called by the probe function in order to avoid a memory leak.
