2020-08-12getitimer(2): delay TIMESPEC_TO_TIMEVAL(9) conversion until copyout(9)cheloha
setitimer(2) works with timespecs in its critical section. It will be easier to merge the two critical sections if getitimer(2) also works with timespecs. In particular, we currently read the uptime clock *twice* during a setitimer(2) swap: we call getmicrouptime(9) in sys_getitimer() and then call getnanouptime(9) in sys_setitimer(). This means that swapping one timer in for another is not atomic with respect to the uptime clock. It also means the two operations are working with different time structures and resolutions, which is potentially confusing. If both critical sections work with timespecs we can combine the two getnanouptime(9) calls into a single call at the start of the combined critical section in a future patch, making the swap atomic with respect to the clock. So, in preparation, move the TIMESPEC_TO_TIMEVAL conversions in getitimer(2) after the ITIMER_REAL conversion from absolute to relative time, just before copyout(9). The ITIMER_REAL conversion must then be done with timespec macros and getnanouptime(9), just like in setitimer(2).
2020-08-12setitimer(2): ITIMER_REAL: don't call timeout_del(9) before timeout_add(9)cheloha
If we're replacing the current ITIMER_REAL timer with a new one we don't need to call timeout_del(9) before calling timeout_add(9). timeout_add(9) does the work of timeout_del(9) implicitly if the timeout in question is already pending. This saves us an extra trip through the timeout_mutex.
2020-08-12Reduce stack usage of kqueue_scan()Visa Hankala
Reuse the kev[] array of sys_kevent() in kqueue_scan() to lower stack usage. The code has reset kevp, but not nkev, whenever the retry branch is taken. However, the resetting is unnecessary because retry should be taken only if no events have been collected. Make this clearer by adding KASSERTs. OK mpi@

2020-08-12skip trying to read disabled bios on RV610Jonathan Gray
Reading the disabled bios on two Dell machines with RV610 passes initial checks but later fails atombios specific checks. This occurs when running amd64 but not i386. Returning early when reading the disabled bios will result in calling radeon_read_platform_bios() and using the bios at 0xc0000 which works for both systems this was reported for semarie@ on Dell OptiPlex 755 RV610 0x1002:0x94C3 0x1028:0x0402 0x00 Andy Bradford on Dell DXP051 RV610 0x1002:0x94C1 0x1028:0x0D02 0x00

2020-08-11setitimer(2): write new timer value in one placecheloha
Rearrange the critical section in setitimer(2) to match that of getitimer(2). This will make it easier to merge the two critical sections in a subsequent diff. In particular, we want to write the new timer value in *one* place in the code, regardless of which timer we're setting. ok millert@

2020-08-11setitimer(2): consolidate copyin(9), input validation, input conversioncheloha
For what are probably historical reasons, setitimer(2) does not validate its input (itv) immediately after copyin(9). Instead, it waits until after (possibly) performing a getitimer(2) to copy out the state of the timer. Consolidating copyin(9), input validation, and input conversion into a single block before the getitimer(2) operation makes setitimer(2) itself easier to read. It will also simplify merging the critical sections of setitimer(2) and getitimer(2) in a subsequent patch. This changes setitimer(2)'s behavior in the EINVAL case. Currently, if your input (itv) is invalid, we return EINVAL *after* modifying the output (olditv). With the patch we will now return EINVAL *before* modifying the output. However, any code dependent upon this behavior is broken: the contents of olditv are undefined in all setitimer(2) error cases. ok millert@

2020-08-11getitimer(2): don't enter itimer_mtx to read ITIMER_REAL itimerspeccheloha
The ITIMER_REAL per-process interval timer is protected by the kernel lock. The ITIMER_REAL timeout (ps_realit_to), setitimer(2), and getitimer(2) all run under the kernel lock. Entering itimer_mtx during getitimer(2) when reading the ITIMER_REAL ps_timer state is superfluous and misleading.

2020-08-10Do not block IPIs when acquiring the rendezvous mutex. Otherwise theVisa Hankala
system would deadlock when a CPU gets blocked by the mutex while another CPU is waiting for the first CPU to finish a rendezvous request. This possibly fixes some hangs on sgi. There should be no effect on loongson and octeon because their interrupt code is sloppy with masking of IPIs. While here, rename the rendezvous mutex to better reflect its use.
