evtchn: pad struct evtchn to 64 bytes
|
|
|
|
The number of struct evtchn in a page must be a power of two. Under
|
|
some workloads performance is improved slightly by padding struct
|
|
evtchn to 64 bytes (a typical cache line size), thus putting the fewer
|
|
per-channel locks into each cache line.
|
|
|
|
This does not decrease the number of struct evtchn's per-page.
