There is no reason to remove the list. This is not noise I believe. Infact by including the list, you are intimating other developers that such work would be available soon Albert, do you think any different. > Sorry, I have to clarify here a bit more. > The descriptors are 16 bytes in length and a cache line is in most > architectures more than 16 bytes in length (in our case either 32 or 64). > This means that cached accesses is not an option for these descriptors. > Background, two adjacent descriptors as be on one cache line may be owned by > different entities (host cpu / network ip). Yes, this is a problem and I can't think of a clean solution. Specially because u-boot (as of today) does not support non-cached memory Albert? > Explicit cache calls that we are added in patch 2/2 are meant for payload of > the package.

Yes, I know that. The descriptors are 16 bytes and they need to be contiguous in memory PS: I have not added the list but I strongly feel that this mail should also go to the uboot list -Vipin > With kind regards, greetings, Frank. > > _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
