Hi, I tested both versions to be sure, but the results are as can be expected:
- both __raw_readl/__raw_writel and readl/writel functions work ok on riscv -
only the original nonvolatile accesses were problematic 2. the additional barrier in readl/writel functions can introduce noticeable slowdown - e.g. with our setup, download speed over tftp for the same image decreased from 460 KiB/s to 118 KiB/s
Can we conclude to keep the raw versions in the patch?
I prefer raw versions too.
