| | | | | | | | | | expectation. This solves the problem, where in a constellation with two (or more) drives, an attempt is made to access a device name for that device using a historic partition letter, like /dev/fd1c. This is supposed to create a symlink to the master device, but previously, the link was always created to /dev/fd0, even if the request was for fd1*.

* Use the correct value when writing the Day Of Week byte in the CMOS.phk2002-12-041-1/+1
| | | | | | | | | | | | | | | | | The correct range is [1...7] with Sunday=1, but we have been writing [0...6] with Sunday=0. The Soekris computers flagged the zero, zapped the date, so if you rebooted your soekris on a sunday, it would come up with a wrong date. Bruce has a more extensive rework of this code, but we will stick with the minimalist fix for now. Spotted by: Soren Kristensen <soren@soekris.com> Thanks to: Michael Sierchio <kudzu@tenebras.com>.

* 1. Fix a comment. Locking _is_ needed (but not done).iwasaki2002-10-171-12/+8
| | | | | | | | | | | | | | | | | | | | | | | | | 2. Update a comment. We now restore much more than RTC updates and interrupts. 3. Order change. Stop interrupts by writing to RTC_STATUSB, restore rate bits for the interrupts by writing to RTC_STATUSA, then enable interrupts again. This seems to be done perfectly backwards in startrtclock(). Otherwise, the idea for this change was obtained from startrtclock(). 4. Don't stop the clock (RTCB_HALT). We only program some control bits and don't want to stop the clock. 5. (Not really related.) Add caveats to the comment about timer_restore(). The update is non-atomic since locking is not done. On locking: 6. rtcin() and writertc() are locked() adequately by splhigh() in RELENG_4, but this locking is null in -current. 7. Doing things in the correct order in (3) combined with (6) is probably enough locking for rtcrestore() in RELENG_4. In -current, the writertc()'s race with rtcintr() unless the BIOS disables RTC interrupts. Submitted by: bde (including commit message) MFC after: 1 week

Move the function from subr_disklabel.c to subr_disk.c, and from <sys/disklabel.h> to <sys/disk.h>. Use the new disk_err() throughout, #include <sys/disk.h> as needed. Bump __FreeBSD_version for the sake of the aac disk drivers #ifdefs. Remove unused disklabel members of softc for aac, amr and mlx, which seem to originally have been intended for diskerr() use, but which only rotted and got Copy&Pasted at least two times to many.

| | | | | | | | | | | | | | | | | previously used "micro-optimization" (count-down loop) into a pessimization. Now the loops are written in the more natural count-up form. Also, while being there, i made the logic in out_fdc() similar to the logic in in_fdc(). The old implementation was a bit bogus anyway since it first tested the DIO bit and only afterwards the RQM bit. However, according to the description of the i82077, the DIO bit is only guaranteed to be valid once the RQM bit is set. Thus, the old implementatoin would have had the chance to misbehave on a controller that is implemented in accordance with the i82077 description (but is not bug-for-bug compatible).

| | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

* Compromise for critical*()/cpu_critical*() recommit. Cleanup the interruptdillon2002-03-271-0/+12
| | | | | | | | | | | | | | | | | | | disablement assumptions in kern_fork.c by adding another API call, cpu_critical_fork_exit(). Cleanup the td_savecrit field by moving it from MI to MD. Temporarily move cpu_critical*() from <arch>/include/cpufunc.h to <arch>/<arch>/critical.c (stage-2 will clean this up). Implement interrupt deferral for i386 that allows interrupts to remain enabled inside critical sections. This also fixes an IPI interlock bug, and requires uses of icu_lock to be enclosed in a true interrupt disablement. This is the stage-1 commit. Stage-2 will occur after stage-1 has stabilized, and will move cpu_critical*() into its own header file(s) + other things. This commit may break non-i386 architectures in trivial ways. This should be temporary. Reviewed by: core Approved by: core

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: selwakeup required calling pfind which would cause lock order reversals with the allproc_lock and the per-process filedesc lock. Solution: Instead of recording the pid of the select()'ing process into the selinfo structure, actually record a pointer to the thread. To avoid dereferencing a bad address all the selinfo structures that are in use by a thread are kept in a list hung off the thread (protected by sellock). When a selwakeup occurs the selinfo is removed from that threads list, it is also removed on the way out of select or poll where the thread will traverse its list removing all the selinfos from its own list. Problem: Previously the PROC_LOCK was used to provide the mutual exclusion needed to ensure proper locking, this couldn't work because there was a single condvar used for select and poll and condvars can only be used with a single mutex. Solution: Introduce a global mutex 'sellock' which is used to provide mutual exclusion when recording events to wait on as well as performing notification when an event occurs. Interesting note: schedlock is required to manipulate the per-thread TDF_SELECT flag, however if given its own field it would not need schedlock, also because TDF_SELECT is only manipulated under sellock one doesn't actually use schedlock for syncronization, only to protect against corruption. Proc locks are no longer used in select/poll. Portions contributed by: davidc
