2025-03-07sysmouse(4): Add wsp(4)-style T-Axis reporting.Joshua Rogers
Neither the ums(4) nor psm(4) reporting can be used by the wsp(4) driver, as they rely on static-length movements, while wsp(4) may need to scroll in large amounts per evdev event push. This style uses a false button-5 press as an indicator that the z-axis movement is a horizontal scroll, otherwise a vertical scroll. Signed-off-by: Joshua Rogers <Joshua@Joshua.Hu>

2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

It can take following values: 0 - no T-axis events (default) 1 - T-axis events are originated in ums(4) driver. 2 - T-axis events are originated in psm(4) driver.

With this change and previous work from ray@ it will be possible to put both in GENERIC, and have one enabled by default, but allow the other to be selected via the loader. (The previous implementation had separate kern.vt.disable and hw.syscons.disable tunables, and would panic if both drivers were compiled in and neither was explicitly disabled.)

2009-05-29Last minute TTY API change: remove mutex argument from tty_alloc().Ed Schouten
I don't want people to override the mutex when allocating a TTY. It has to be there, to keep drivers like syscons happy. So I'm creating a tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex() should eventually be removed. The advantage of this approach, is that we can just remove a function, without breaking the regular API in the future. Notes: svn path=/head/; revision=193018
2008-11-08Reduce the default baud rate of PTY's to 9600.Ed Schouten
On RELENG_6 (and probably RELENG_7) we see our syscons windows and pseudo-terminals have the following buffer sizes: | LINE RAW CAN OUT IHIWT ILOWT OHWT LWT COL STATE SESS PGID DISC | ttyv0 0 0 0 7680 6720 2052 256 7 OCcl 1146 1146 term | ttyp0 0 0 0 7680 6720 1296 256 0 OCc 82033 82033 term These buffer sizes make no sense, because we often have much more output than input, but I guess having higher input buffer sizes improves guarantees of the system. On MPSAFE TTY I just sent both the input and output buffer sizes to 7 KB, which is pretty big on a standard FreeBSD install with 8 syscons windows and some PTY's. Reduce the baud rate to 9600 baud, which means we now have the following buffer sizes: | LINE INQ CAN LIN LOW OUTQ USE LOW COL SESS PGID STATE | ttyv0 1920 0 0 192 1984 0 199 7 2401 2401 Oil | pts/0 1920 0 0 192 1984 0 199 5631 1305 2526 Oi This is a lot smaller, but for pseudo-devices this should be good enough. You need to do a lot of punching to fill up a 7.5 KB input buffer. If it turns out things don't work out this way, we'll just switch to 19200 baud. Notes: svn path=/head/; revision=184771
2008-08-24Make sysmouse(4) use its own locks, instead of using Giant.Ed Schouten
When I changed syscons(4) to work with the MPSAFE TTY code, I just locked all device nodes down using the compatibility feature that allows you to override the TTY's lock (Giant in this case). Upon closer inspection, it seems sysmouse(4) only has two internal variables that need locking: mouse_level and mouse_status. I haven't done any performance benchmarks on this, though I think it won't have any dramatic improvements on the system. It is good to get rid of Giant here, because the third argument of tty_alloc() has only been added to ease migration to MPSAFE TTY. It should not be used when not needed. While there, remove SC_MOUSE, which is a leftover from the MPSAFE TTY import. Notes: svn path=/head/; revision=182109
2008-08-20Integrate the new MPSAFE TTY layer to the FreeBSD operating system.Ed Schouten
The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

2002-04-01Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin
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.
