Dear sun york-R58495,
In message C707E9F4D8007146BF8DC1424B113AC70B3A6A83@039-SN2MPN1-012.039d.mgd.msft.net you wrote:
I think it is best to keep this patch as it and stick with the original flush_cache name. It uses the existing function flush_cache() which is available for most (if not all) architectures. Splitting the dcache and icache not only adds more code, but architecture-dependent code.
As mentioned before: reusing existing code is fine, but we already have commands for cache handling, and adding arbitrary new ones to implement combinations of functions makes does not scale. Assume tomorrow someone needs to add more ganular handling for example regarding L2 caches, etc. Would you suggest to add another set of new commands, then? This makes no sense.
Please implement IC related operations as subcommands to the "icache" command, and DC releated ones as subcommands to "dcache".
[In the example of L2 cache above, it would be for example sufficient to add a "-L2" option to the "icache" / "dcache" commands.]
Best regards,
Wolfgang Denk
