| | | | | | | | | | | | | scenario into #ifdef DEBUG. This makes my cluster with Belkin KVM switch completely usable, even if the KVM switch and mouse get a bit confused sometimes. Without this, when the mouse gets confused, all sorts of crud gets spammed all over the screen. With this, the mouse may appear dead for a second or three, but it recovers silently.

* Significantly reduce the "jitter" that is typical for PS/2 miceAlfred Perlstein2003-12-111-110/+256
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when using a KVM. There is no actual solution possible, but this gets us pretty close. Typically when switching back to a FreeBSD box and moving the mouse wild data is produced, because the protocol's validation/checksum system is extremely weak it is impossible to determine that we're out of sync before dropping several bogus packets to user land. The actual solution that appears to offer the best clamping of jitter is to buffer the mouse packets if we've not seen mouse activity for more than .5 seconds. Then waiting to flush that data for 1/20th of a second. If within that 20th of a second we get any packets that do fail the weak test we drop the entire queue and back off accepting data from the mouse for 2 seconds and then repeat the whole deal. You can still get _some_ jitter, notably if you switch to the FreeBSD box, then move the mouse just enough to generate one or two packets. Those packets may be bogus, but may still pass the validity check. One way to finally kill the problem once and for all is to check the initial packets for "wild" values. Typically one sees packets in the +/-60 range during normal operation, however when bogus data is generated it's typically near the outer range of +/-120 or more, those packets would be a good candidate for dropping or clamping. I've been running with this for several weeks now and it has significantly helped me stay sane even with a piece of junk Belkin KVM causing wild jitter each and every time I switch. Lastly I'd like to note that my experience with Windows shows me that somehow the Microsoft PS/2 driver typically avoids this problem, but that may only be possible when running the mouse in a dumb-ed down PS/2 mode that Belkin recommends on their site.

This way if the device is disabled it is never created.

| | | | | | | | | | | | | | | | | of KBDIO_DEBUG which may be defined in the kernel config (as it is in NOTES). This kind of bug is a _really_ horribly thing as we end up with one bit of code thinking a particular structure is 136 bytes and another that it is only 112 bytes. Ideally all places would remember to #include the right "opt_foo.h" file, but I think in practice file containing the variable sized struct should #include it explicitly as a precaution.

* Fixes to make select/poll mpsafe.Alfred Perlstein2002-03-141-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=92252

* Hack for the "out-of-sync" error.Kazutaka YOKOTA2001-10-131-109/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Count the number of this error. - When the error is detected for the first time, the psm driver will throw few data bytes (up to entire packet size) and see if it can get back to sync. - If the error still persists, the psm driver disable/enable the mouse and see if it works. - If the error still persists and the count goes up to 20, the psm driver reset and reinitialize the mouse. The counter is reset to zero. - It also discards an incomplete data packet when the interval between two consequtive bytes are longer than pre-defined timeout (2 seconds). The last byte which arrived late will be regarded as the first byte of a new packet. This is louie's idea. You may see the following error logs during the above operations: "psmintr: delay too long; resetting byte count" "psmintr: out of sync (%04x != %04x)" "psmintr: discard a byte (%d)" "psmintr: re-enable the mouse" "psmintr: reset the mouse" MFC after: 1 month Notes: svn path=/head/; revision=84880
