MFC r340912,r340913:
psm(4): Revert r328640 and add minimal support for active AUX port multiplexers
Active PS/2 multiplexing is a method for attaching up to four PS/2 pointing devices to a computer. Enabling of multiplexed mode allows commands to be directed to individual devices using routing prefixes. Multiplexed mode reports input with each byte tagged to identify its source. This method differs from one currently supported by psm(4) where so called guest device (trackpoint) is attached to special interface located on the host device (touchpad) and latter performs guest protocol conversion to special encapsulation packet format.
At present time active PS/2 multiplexing is used in some models of HP laptops e.g. EliteBook 8560w, 9470m. Enabling of absolute operation mode on such touchpads is connected with following problems: 1. Touchpad's port priority is lower than trackpoint's. That blocks information queries thus prevents touchpad detection and configuration. 2. Touchpad and trackpoint have different protocol packet sizes and sync bytes.
As PS/2 usage is on decline only minimal possible set of changes to support Synaptics touchpad and generic mouses is implemented. Active multiplexing mode is enabled only at probe stage to scan through attached PS/2 devices to query and configure Synaptics touchpad. After touchpad has been configured, mux is switched back to legacy (hidden multiplexing) mode to perform normal interrupt-driven input data processing. Overflow bit values rather than tags are used to separate packets produced by different devices. Switching back to legacy mode allows to avoid psm(4) and atkbd(4) rework to support 4 instances of mouse driver.
Note: While in hidden multiplexing mode KBC does some editing of the packet stream. It remembers the button bits from the last packet received from each device, and replaces the button bits of every packet with the logical OR of all devices’ most recent button bits. This sort of button crosstalk results in spurious button events which are inhibitted with various tricks. E.g. trackpoint middle button events are suppressed while trackpad surface is touched and touchpad left and right button events are suppressed if corresponding trackpoint buttons are pressed.

Unbreak mouse on resume on Thinkpads when hw.psm.trackpoint_support=0, which is default. It was broken in r281441.
It appears that set_trackpoint_parameters() call on resume disables the mouse. So, we need not call it on resume if hw.psm.trackpoint_support=0.
The problem is that the probe functions are used both for probing and for reiniting on resume. And the absense of the softc parameter is used as a mark to distinguish reinit and probe, which is quite ugly. At the same time the softc parameter is needed to call set_trackpoint_parameters().
o Change the arguments of probefunc_t to always supply the softc, and use additional enum argument to tell probing from initing. o Don't call set_trackpoint_parameters() from global doinitialize(), instead call it from the enable_trackpoint() only. o In enable_synaptics() call enable_trackpoint() in both probe and reinit cases.

synaptics: more support for semi-MT trackpads.
Several improvements to the Synaptics driver to support semi-multitouch trackpads and some other fixes:
- Two finger scrolling support for "semi-MT" touchpads. Those include many of the older Synaptics touchpads before "true" multitouch support (indicated by capMultiFinger). Semi-MT touchpads can report a second finger position, but the X or Y coordinate may be swapped with some coordinate of the first finger. This is a result of how the hardware works internally. Therefore, all that can be reliably extracted is the bounding box of the two finger positions. Semi-MT touchpads can be recognized by the capAdvancedGestures capability bit. After setting the mode byte, advanced gestures mode has to be enabled. Then, data packets compatible with the capMultiFinger format are sent, so the same two finger scrolling code can be leveraged. Enabling advanced gestures mode on true multitouch touchpads should be harmless. Linux seems to always enable advanced gestures mode.
- Put mode setting logic into own functions synaptics_preferred_mode() and synaptics_set_mode() to have this in one place. synaptics_passthrough_on() and synaptics_passthrough_off() currently always use 0xc1 as the mode byte, which may be wrong for touchpads that don't have capExtended.
- Expose X and Y resolution of touchpad to userland. Also expose minimum and maximum X and Y coordinates. This is useful for programs in userspace that read raw PSM packets (with PSM_LEVEL_NATIVE enabled) and need to interpret the coordinates.
- Also send "extended w mode" packets (see section 3.2.9 of 511-000275-01_RevB.pdf) to userspace if PSM_LEVEL_NATIVE is enabled. This is useful for userspace programs/drivers such as xf86-input-synaptics that can handle these packets.
- Fix parsing of nExtendedQueries, and request extended/continued capability bits depending on this value.
- capReportsMax, capClearPad, capAdvancedGestures and capCoveredPad must be extracted from status[0] and not status[2], I think.

Enable two finger scrolling by default and disable the edge scrolling if the touchpad has no physical zone for it. Disable directional scrolling by default to avoid using extended buttons as scroll buttons.
Add support for ClickPad. On Lenovo laptops, this is the button reported when one presses the touchpad.
While there, fix a problem where the extended buttons were not reporting the button release event correctly: we need to save the state of the buttons and report it to sysmouse until we receive a packet from the touchpad indicating the button has been released. This makes it possible to use an extended button to resize a window. On Lenovo laptops, the major buttons are actually reported as extended buttons.

Make the newbus subsystem Giant free by adding the new newbus sxlock. The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped.
For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens.
Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware.

Try to detect a Synaptics touchpad before IntelliMouse. Some touchpads will pretend to be IntelliMouse (which have a few more features than generic mice) causing the IntelliMouse probe to work and the Synaptics code never to be called.
This should not break "real" IntelliMouse because the Synaptics detection code is fairly specific.

- Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source files after they were repo-copied to sys/dev/atkbdc. The sources of atkbdc(4) and its children were moved to the new location in preparation for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in order to not further scatter them over the whole tree which would have been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another reason for the repo-copies was that some of the sources were misfiled, e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly. Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't ISA-specific. - Separate the parts of atkbdc_isa.c which aren't actually ISA-specific but are shareable between different atkbdc(4) bus front-ends into atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource() respectively in atkbdc_isa.c instead of rolling own versions. - Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for atkbdc(4). PS/2 controllers and input devices are used on a couple of Sun OEM boards and occur on either the EBus or the ISA bus. Depending on the board it's either the only on-board mean to connect a keyboard and mouse or an alternative to either RS232 or USB devices. - Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled without isa(4) (e.g. for EBus-only machines). This ISA-specific part isn't separated into its own source file, yet, as it requires more work than was feasible for 6.0 in order to do it in a clean way. Actually philip@ is working on a rewrite of psm(4) so a more comprehensive clean-up and separation of hardware dependent and independent parts is expected to happen after 6.0.

Forced commit to add additional comment. o Add MOUSE_PS2_TAP into syncmask[0] correctly when we're built with PSM_CONFIG_FORCETAP. The previous code from revision 1.56 attempted to do this but updated the a mask variable that would be clobbered later. o If syncmask[1] hasn't yet been set when ioctl(MOUSE_GETMODE) is called, zero syncmask[0] and syncmask[1] so that sync validation is effectively disabled in userland applications and moused doesn't misbehave. The psm driver performs sync validation so there is no loss in functionality in clearing the sync mask. o If PSM_NEED_SYNCBITS is set, setup syncmask[1], even if it's already correct. This prevents the PSM_NEED_SYNCBITS bit from being left on after a re-initialisation and erroneously causing a subsequent out-of-sync packet to mis-set syncmask[1].

Improve sync recovery algorithm: o Remove PSM_SYNCERR_THRESHOLD1. This value specified how many sync errors were required before the mouse is re-initialised. Re-initialisation is now done after (packetsize * 2) sync errors as things aren't likely to improve after that.
o Reset lastinputerror when re-initialisation occurs. We don't want to continue to drop data after re-initialisation.
o Count the number of failed packets independently of the syncerrors statistic. syncerrors is useful for recovering sync within a single packet. pkterrors allows us to detect when the mouse changes its packet mode due to some external event (e.g. KVM switch).
o Reinitialize the mouse if we see more than psmpkterrthresh errors during the validation period. The validation period begins as soon as a sync error is detected and continues until psmerrsecs/msecs time has elapsed. The defaults for these two values force a reset if we see two packet errors in a 2 second period. This allows rapid detection of packet framing errors caused by the mouse changing packet modes.
o Export psmpkterrthresh as a sysctl
o Export psmloglevel as a sysctl.
o Enable more debugging code to be enabled at runtime via psmloglevel.
o Simplify verbose conditioned loging by using a VLOG macro.
o Add several comments describing the sync recovery algorithm of this driver.

Defer the capture of the "expected sync bits" until the first "normal" data packet is received from the mouse. In the case of many KVM's, this avoids a bug in their mouse emulation that sends back incorrect sync when you explicitly request a data packet from the mouse. Without this change, you must force the driver into stock PS/2 mode or be flooded with a never ending stream of "out of sync" messages on these KVMs.

Significantly reduce the "jitter" that is typical for PS/2 mice 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.

Fixes to make select/poll mpsafe.
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.

Hack for the "out-of-sync" error.
- 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"

Yet another turn of workaround for psm/ACPI/PnP BIOS problems currently experienced in -CURRENT.
This should fix the problem that the PS/2 mouse is detected twice if the acpi module is not loaded on some systems.

Refine ACPI/PnP BIOS probe/attach routines a bit.
- Add workaround for the problematic PnP BIOS which does not assign irq resource for the PS/2 mouse device node; if there is no irq assigned for the PS/2 mouse node, refer to device.hints for an irq number. If we still don't find an irq number in the hints database, use a hard-coded value. - Delete unused ivars. - Bit of clean up in probe/attach. - Add PnP ID for the PS/2 mouse port on some IBM ThinkPad models.

KSE Milestone 2 Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

Update the atkbdc, atkbd, and psm drivers to probe/attach more cleanly and consistently in all APCI, PnP BIOS, and "hint" cases.
NOTE: this doesn't necessarily solve the problem that the PS/2 mouse is not detected after the recent ACPI update.

- Add a hack for "psmintr: out of sync.." This is NOT a fix, but a hack! Add `flags 0x8000' to the psm driver to enable it. The psm driver will try to get out of out-of-sync situation by disabling the mouse and immediately enable it again.
If you are seeing this out-of-sync problem because of an incompetent(?!) KVM switch, this hack will NOT be good for you. However, if you are occasionally seeing the problem because of lost mouse interrupt, this might help.

- Add Support for the following PS/2 mice: - Microsoft IntelliMouse Explorer: 2 buttons on top, 2 side buttons and a wheel which also acts as the middle button. The mouse is recognized as "IntelliMouse Explorer". - Genius NetScroll Optical: 2 buttons on top, 2 side buttons and a wheel which also acts as the middle button. The mouse is recognized as "NetMouse/NetScroll Optical". - MouseSystems SmartScroll Mouse (OEM from Genius?): 3 buttons on top, 1 side button and a wheel. The mouse is recognized as Genius "NetScroll". - IBM ScrollPoint: 2 buttons on top and a stick between the buttons. The stick can perform "horizontal scroll" in W*ndows environment. The horizontal movement of the stick is detected. It is currently mapped to the Z axis movement in the same way as the first wheel. The mouse is recognized as "MouseMan+", as it is considered to be a variation of MouseMan. - A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement of the second wheel is reported as the Z axis movement in the same way as the first wheel. These mice are recognized as "4D Mouse" and "4D+ Mouse". - Tweak IntelliMouse support code a bit so that less-than-compatible wheel mice can work properly with the psm driver. - Add driver configuration flags which correspond to the kernel options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't need to recompile the kernel when we need these functions. - Properly keep track of the irq resource. - Add a watchdog timer in case interrupts are lost (experimental). - Add `detach' function (experimental).

Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().

Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE (ditto!)

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA.
(Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.)
This is a checkpoint of work-in-progress, but is quite functional.
The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

* Add hooks to allow the X server to access I/O ports and memory. * Update drivers to the latest version of the bus interface.
The ISA drivers' use of the new resource api is minimal. Garrett has some much cleaner drivers which should be more easily shared between i386 and alpha. This has only been tested on cia based machines. It should work on lca and apecs but I might have broken something.
