But even if we have several threads sometimes, we have no rights to process queue in parallel as it will break original requests serialization that is critically important for some setups.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Add support for automatic promotion of 4KB page mappings to 2MB page mappings. Automatic promotion can be enabled by setting the tunable "vm.pmap.pg_ps_enabled" to a non-zero value. By default, automatic promotion is disabled. Tested by: kris 2. To date, we have assumed that the TLB will only set the PG_M bit in a PTE if that PTE has the PG_RW bit set. However, this assumption does not hold on recent processors from Intel. For example, consider a PTE that has the PG_RW bit set but the PG_M bit clear. Suppose this PTE is cached in the TLB and later the PG_RW bit is cleared in the PTE, but the corresponding TLB entry is not (yet) invalidated. Historically, upon a write access using this (stale) TLB entry, the TLB would observe that the PG_RW bit had been cleared and initiate a page fault, aborting the setting of the PG_M bit in the PTE. Now, however, P4- and Core2-family processors will set the PG_M bit before observing that the PG_RW bit is clear and initiating a page fault. In other words, the write does not occur but the PG_M bit is still set. The real impact of this difference is not that great. Specifically, we should no longer assert that any PTE with the PG_M bit set must also have the PG_RW bit set, and we should ignore the state of the PG_M bit unless the PG_RW bit is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | frequency generation and what frequency the generated was anyones guess. In general the 32.768kHz RTC clock x-tal was the best, because that was a regular wrist-watch Xtal, whereas the X-tal generating the ISA bus frequency was much lower quality, often costing as much as several cents a piece, so it made good sense to check the ISA bus frequency against the RTC clock. The other relevant property of those machines, is that they typically had no more than 16MB RAM. These days, CPU chips croak if their clocks are not tightly within specs and all necessary frequencies are derived from the master crystal by means if PLL's. Considering that it takes on average 1.5 second to calibrate the frequency of the i8254 counter, that more likely than not, we will not actually use the result of the calibration, and as the final clincher, we seldom use the i8254 for anything besides BEL in syscons anyway, it has become time to drop the calibration code. If you need to tell the system what frequency your i8254 runs, you can do so from the loader using hw.i8254.freq or using the sysctl kern.timecounter.tc.i8254.frequency.

* Fix a nit with the 'nofoo' options where 'foo' is mapped to 'nonofoo'John Baldwin2008-03-262-4/+4
| | | | | | | | | | | | | | | | (such as 'atime' vs 'noatime'). The filesystems will always see either 'nofoo' or 'nonofoo', never plain 'foo'. As such, their list of valid mount options should include 'nofoo' instead of 'foo'. With this fix, you can do 'mount -u -o atime' on a FFS filesystem that isn't marked as noatime without getting an error. You can also update a noatime FFS filesystem mounted via mount(2) (e.g. 6.x /sbin/mount binary) to 'atime' using nmount(2) (e.g. 7.x /sbin/mount binary).

* The "free-lance" timer in the i8254 is only used for the speakerPoul-Henning Kamp2008-03-2626-332/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | these days, so de-generalize the acquire_timer/release_timer api to just deal with speakers. The new (optional) MD functions are: timer_spkr_acquire() timer_spkr_release() and timer_spkr_setfreq() the last of which configures the timer to generate a tone of a given frequency, in Hz instead of 1/1193182th of seconds. Drop entirely timer2 on pc98, it is not used anywhere at all. Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if they exist, and do nothing otherwise. Remove prototypes and empty acquire-/release-timer() and sysbeep() functions from the non-beeping archs. This eliminate the need for the speaker driver to know about i8254frequency at all. In theory this makes the speaker driver MI, contingent on the timer_spkr_*() functions existing but the driver does not know this yet and still attaches to the ISA bus. Syscons is more tricky, in one function, sc_tone(), it knows the hz and things are just fine. In the other function, sc_bell() it seems to get the period from the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode the 1193182 and leave it at that. It's probably not important. Change a few other sysbeep() uses which obviously knew that the argument was in terms of i8254 frequency, and leave alone those that look like people thought sysbeep() took frequency in hertz. This eliminates the knowledge of i8254_freq from all but the actual clock.c code and the prof_machdep.c on amd64 and i386, where I think it would be smart to ask for help from the timecounters anyway [TBD].

* Add the new kernel-mode NFS Lock Manager. To use it instead of theDoug Rabson2008-03-2680-525/+20923
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | user-mode lock manager, build a kernel with the NFSLOCKD option and add '-k' to 'rpc_lockd_flags' in rc.conf. Highlights include: * Thread-safe kernel RPC client - many threads can use the same RPC client handle safely with replies being de-multiplexed at the socket upcall (typically driven directly by the NIC interrupt) and handed off to whichever thread matches the reply. For UDP sockets, many RPC clients can share the same socket. This allows the use of a single privileged UDP port number to talk to an arbitrary number of remote hosts. * Single-threaded kernel RPC server. Adding support for multi-threaded server would be relatively straightforward and would follow approximately the Solaris KPI. A single thread should be sufficient for the NLM since it should rarely block in normal operation. * Kernel mode NLM server supporting cancel requests and granted callbacks. I've tested the NLM server reasonably extensively - it passes both my own tests and the NFS Connectathon locking tests running on Solaris, Mac OS X and Ubuntu Linux. * Userland NLM client supported. While the NLM server doesn't have support for the local NFS client's locking needs, it does have to field async replies and granted callbacks from remote NLMs that the local client has contacted. We relay these replies to the userland rpc.lockd over a local domain RPC socket. * Robust deadlock detection for the local lock manager. In particular it will detect deadlocks caused by a lock request that covers more than one blocking request. As required by the NLM protocol, all deadlock detection happens synchronously - a user is guaranteed that if a lock request isn't rejected immediately, the lock will eventually be granted. The old system allowed for a 'deferred deadlock' condition where a blocked lock request could wake up and find that some other deadlock-causing lock owner had beaten them to the lock. * Since both local and remote locks are managed by the same kernel locking code, local and remote processes can safely use file locks for mutual exclusion. Local processes have no fairness advantage compared to remote processes when contending to lock a region that has just been unlocked - the local lock manager enforces a strict first-come first-served model for both local and remote lockers.
