The engine is used in Hisilicon Hi1610 and more further ICT SoC.
The hns driver uses __raw_writeq which is only defined in 64BIT environments. Trying to compile the driver in a 32BIT environment results in errors. Only COMPILE_TEST when 64BIT is defined. Fixes: 7d1b6a678e0b ("IB/hns: Support compile test for hns RoCE driver") Signed-off-by: Matan Barak <matanb@mellanox.com> --- Hi Lijun and Wei, This is a small fix for the compile test patch I posted. The original patch added the support to compile the hns RoCE driver in architectures other than ARM64 to ease development. However, __raw_writeq is used in your driver and it's only available in 64bit environments. Therefore, I've added the required condition in the Kconfig. Please note that compiling the code over 64bit architectures that declare 64BIT but don't declare ARCH_DMA_ADDR_T_64BIT produces compilation warnings. I'm not aware of such architectures though.
