Some hypervisors (such as Hertzner) allow msr read of DE_CFG (which does not indicate bit 9 set, but they could have a firmware fix) but then block a msr write to bit 9 (which disables enough AVX optimizations to prevent the exfiltration of data), with a fault. So let's also check the HV bit before we decide to modify the bit. hypervisors are expected to set that bit. tested by lucas at sexy dot is. with jsg, ok mlarkin |

cpu_idle_{enter,leave} are no-ops on amd64 now, so just #define away the calls ok deraadt@ mpi@ miod@ |

Extend the PCKBC_CANT_TRANSLATE feature, specific to Tadpole/RDI hardware, to also support scan code set #3 in addition to the existing scan code set #2. This makes the built-in keyboard on the Tadpole UltraBook IIe work. |

statclock: move profil(2), GPROF code to profclock(), gmonclock() This patch isolates profil(2) and GPROF from statclock(). Currently, statclock() implements both profil(2) and GPROF through a complex mechanism involving both platform code (setstatclockrate) and the scheduler (pscnt, psdiv, and psratio). We have a machine-independent interface to the clock interrupt hardware now, so we no longer need to do it this way. - Move profil(2)-specific code from statclock() to a new clock interrupt callback, profclock(), in subr_prof.c. Each schedstate_percpu has its own profclock handle. The profclock is enabled/disabled for a given CPU when it is needed by the running thread during mi_switch() and sched_exit(). - Move GPROF-specific code from statclock() to a new clock interrupt callback, gmonclock(), in subr_prof.c. Where available, each cpu_info has its own gmonclock handle . The gmonclock is enabled/disabled for a given CPU via sysctl(2) in prof_state_toggle(). - Both profclock() and gmonclock() have a fixed period, profclock_period, that is initialized during initclocks(). - Export clockintr_advance(), clockintr_cancel(), clockintr_establish(), and clockintr_stagger() via <sys/clockintr.h>. They have external callers now. - Delete pscnt, psdiv, psratio. From schedstate_percpu, also delete spc_pscnt and spc_psdiv. The statclock frequency is not dynamic anymore so these variables are now useless. - Delete code/state related to the dynamic statclock frequency from kern_clockintr.c. The statclock frequency can still be pseudo-random, so move the contents of clockintr_statvar_init() into clockintr_init(). With input from miod@, deraadt@, and claudio@. Early revisions cleaned up by claudio. Early revisions tested by claudio@. Tested by cheloha@ on amd64, arm64, macppc, octeon, and sparc64 (sun4v). Compile- and boot- tested on i386 by mlarkin@. riscv64 compilation bugs found by mlarkin@. Tested on riscv64 by jca@. Tested on powerpc64 by gkoehler@. |
