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, exceptwhen they reference device drivers that are listed in UPDATING.Obtained from: //depot/projects/mpsafetty/...Approved by: philip (ex-mentor)Discussed: on the lists, at BSDCan, at the DevSummitSponsored by: Snow B.V., the Netherlandsdcons(4) fixed by: kan List of files: /freebsd-12.1/sys/modules/rc/Makefile Wed, 20 Aug 2008 08:31:58 +0000 Ed Schouten <ed@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/sys/modules/rc/Makefile#82292344 Let modules use the kernel's opt_*.h files if built along withthe kernel by wrapping all targets for fake opt_*.h files in.if defined(KERNBUILDDIR). Thus, such fake files won't becreated at all if modules are built with the kernel.Some modules undergo cleanup like removing unused or unneededoptions or .h files, without which they wouldn't build this wayor the other.Reviewed by: ruTested by: no binary changes in modules built aloneTested on: i386 sparc64 amd64 List of files: /freebsd-12.1/sys/modules/rc/Makefile Fri, 14 Oct 2005 23:30:17 +0000 Yaroslav Tykhiy <ytykhiy@gmail.com> http://172.16.0.5:8080/history/freebsd-12.1/sys/modules/rc/Makefile#9c62b3ee Make TTYHOG tunable.Reviewed by: mike (mentor) List of files: /freebsd-12.1/sys/modules/rc/Makefile Wed, 05 Mar 2003 08:16:29 +0000 David Schultz <das@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/sys/modules/rc/Makefile#599c57a9 - New-bussify the rc(4) device driver.- Add detach support to the driver so that you can kldunload the module. Note that currently rc_detach() fails to detach a unit if any of its child devices are open, thus a kldunload will fail if any of the tty devices are currently open.- sys/i386/isa/ic/cd180.h was moved to sys/dev/ic/cd180.h as part of this change.Requested by: rwatsonTested by: rwatson List of files: /freebsd-12.1/sys/modules/rc/Makefile Wed, 23 Oct 2002 15:53:09 +0000 John Baldwin <jhb@FreeBSD.org>
