In invalidating cache

This leads to varying parts of my packet information being "chopped off". A solution to this, as stated in the Xilinxs documentation seems to be to cache align the... I don't know if it is my attempt that doesn't work, or if it simply doesn't fix the problem.

One of the problems most customer's face is that with a large number of cache entries, it can be difficult to find specific entries as there is no search function.

Once you have selected the cache instance to view, there are several views into the cache entries.

Notice that you can invalidate each individual entry or you can just hit the clear cache to clear them all.

One view of the cache entries by dependency id which allows you to group the entries based on the id.

Except that using void Xil_DCache Invalidate Range(unsigned int adr, unsigned len) invalidates a cache line but not necessarily where the packet information starts.

It looks at the address I pass to it, then it moves from there to the start of the first cache line and only then begins invalidating the cache. I have tried simply disabling the entire cache at the start of the program, however this doesn't seem to work.I would to briefly discuss the use of the Cache Monitor Application.There is a distinct difference in the Cache Monitor provided with Web Sphere and the Extended Cache Monitor.I then copy out the packets into some linked list containers that I have before returning the BDs to the hardware.My problem is that when I go to read the data that the BD points to, the cached data is wrong, so I invalidate it.However, when you make updates to an asset, you may want those changes to take effect immediately.Invalidating your CDN (Content Delivery Network) cached content lets you quickly update assets that are delivered by Dynamic Media, instead of waiting for the cache to expire. When my program performs a load operation with acquire semantics/store operation with release semantics or perhaps a full-fence, it invalidates the CPU's cache. When you perform a load without fences or mutexes, then the loaded value could potentially come from anywhere, i.e, caches, registers (by way of compiler optimizations), or RAM... In most mutex implementations, when you acquire a mutex, a fence is always applied, either explicitly (e.g., mfence, barrier, etc.) or implicitly (e.g., lock prefix to lock the bus on x86).My question is this: which part of the cache is actually invalidated? This causes the cache-lines of all caches on the path to be invalidated.I have a problem that I am trying to fix in a program I have written.I receive internet packets, the Rx interrupt affects a bool so that in a loop I can to to then request the Rx BD from the hardware.
