Julien Grall a001c9d95c xen/events: fifo: Make it running on 64KB granularity ... Only use the first 4KB of the page to store the events channel info. It means that we will waste 60KB every time we allocate page for: * control block: a page is allocating per CPU * event array: a page is allocating everytime we need to expand it I think we can reduce the memory waste for the 2 areas by: * control block: sharing between multiple vCPUs. Although it will require some bookkeeping in order to not free the page when the CPU goes offline and the other CPUs sharing the page still there * event array: always extend the array event by 64K (i.e 16 4K chunk). That would require more care when we fail to expand the event channel.
