The only checks getting done even later are the long mode specific ones for system descriptors (which we don't support yet) and 64-bit code segments (i.e. anything touching other than the attribute byte). Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx> Reviewed-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> x86/hvm: Correct the position of the %cs L/D checks Contrary to the description in the software manuals, in Long Mode, attempts to load %cs check that D is not set in combination with L before the present flag is checked. This can be observed because the L/D check fails with #GP before the presence check failes with #NP. This change partially reverts c/s 78ff18c90 "x86: defer not-present segment checks", taking it back to how it was in the v1 submission.

If vcpu x has run for 200us, and sched_ratelimit_us is 1000us, continue running x _but_ return 1000us-200us as the next time slice. This way, next scheduling point will happen in 800us, i.e., exactly at the point when x crosses the threshold, and can be descheduled (if appropriate). Right now (without this patch), we're always returning sched_ratelimit_us (1000us, in the example above), which means we're (potentially) allowing x to run more than it should have been able to. Note that, however, in order to avoid setting timers to very short intervals, which is part of the purpose of rate limiting, we never use a time slice smaller than a well defined threshold. Such threshold (CSCHED_MIN_TIMER defined in this patch) is, in general independent from rate limiting, but it looks a good idea to set it to the minimum possible ratelimiting value.
