4lDO2 7fc4dee572 Clobber xmm0-xmm15 in x86_64 syscall wrapper. 2026-09-04 22:20:43 +02:00
4lDO2 f4d59db53e Add additional counter for syscall switches. 2026-09-02 13:16:09 +02:00
4lDO2 d2874a167d Avoid fetch_add for context switch count. 
Together with the previous commit, this reduces base IPC latency by 1%.
 2026-09-02 13:09:56 +02:00
4lDO2 9329213e38 Avoid stats fetch_add when exclusively incremented. 
x.store(x.load() + 1) is valid if all other threads are strictly
read-only (and even then, for counters the damage would be much limited
anyway).
