- 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.

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.

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.

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" MFC after: 1 month

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.

/* Tunables */
Add new "hw.psm.tap_enabled" tunable and sysctl. This tunable allows one to enable (1) or disable (0) gestures like tap and tap-hold on Synaptics TouchPad when the Extended mode isn't enabled (ie. "hw.psm.synaptics_support" not set). By default, the value is -1 in order to keep the current behaviour of not enabling/disabling gestures explicitly.

Reduce diffs to work in progress before checking in serious changes. o Move the sysctls under debug.psm.* and hw.psm.* making them a bit clearer and more consistent with other drivers. o Remove the debug.psm_soft_timeout sysctl. It was introduced many moons ago in r1.64 but never referenced anywhere. o Introduce hw.psm.tap_threshold and hw.psm.tap_timeout to control the behaviour of taps on touchpads. People might like to fiddle with these if tapping seems to slow or too fast for them. o Add debug.psm.loglevel as a tunable so that verbosity can be set easily at boot-time (to watch probes and such) without having to compile a kernel with options PSM_DEBUG=N.

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. PR: kern/120833 Submitted by: Eygene Ryabinkin <rea-fbsd -at- codelabs.ru> MFC after: 1 week

This commit should be a extensive NO-OP: Reformat and initialize correctly all "struct cdevsw". Initialize the d_maj and d_bmaj fields. The d_reset field was not removed, although it is never used. I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way. Vinum and i4b not modified, patches emailed to respective authors.

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).

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).

Add new "hw.psm.tap_enabled" tunable and sysctl. This tunable allows one to enable (1) or disable (0) gestures like tap and tap-hold on Synaptics TouchPad when the Extended mode isn't enabled (ie. "hw.psm.synaptics_support" not set). By default, the value is -1 in order to keep the current behaviour of not enabling/disabling gestures explicitly.

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.

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.

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).

Reduce diffs to work in progress before checking in serious changes. o Move the sysctls under debug.psm.* and hw.psm.* making them a bit clearer and more consistent with other drivers. o Remove the debug.psm_soft_timeout sysctl. It was introduced many moons ago in r1.64 but never referenced anywhere. o Introduce hw.psm.tap_threshold and hw.psm.tap_timeout to control the behaviour of taps on touchpads. People might like to fiddle with these if tapping seems to slow or too fast for them. o Add debug.psm.loglevel as a tunable so that verbosity can be set easily at boot-time (to watch probes and such) without having to compile a kernel with options PSM_DEBUG=N.

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.

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.

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).

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).

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.

Introduce a tunable to disable support for Synaptics touchpads. A number of people have reported problems (stickyness, aiming difficulty) which is proving difficult to fix, so this will default to disable until sometime after 5.3R. To enable Synaptics support, set the 'hw.psm.synaptics_support=1' tunable. MT5 candidate. Approved by: njl

- 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.

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.
