Handle out of ordered PCIe completions

Hi, 

 

If am facing an issue while handling out of ordered PCIe completions.  

 

Its clear from the Specs that completions corresponding to single read request always return in order. 

 

But in my application my block size is 8KB. So i need to split my request into 2kB x 4. 

 

So to handle out of ordered completions from multiple request I need a Big Buffer. 

 

Is there a second option to handle this Issue????? 

 

Thanks in advance

Well, the only other option is to wait for all completions for a single read request to arrive and then to issue the next request. Sorry, but there is nothing else you can do about it.
