2016-08-19Remove the si(4) driver and sicontrol(8) for Specialix serial cards.John Baldwin
The si(4) driver supported multiport serial adapters for ISA, EISA, and PCI buses. This driver does not use bus_space, instead it depends on direct use of the pointer returned by rman_get_virtual(). It is also still locked by Giant and calls for patch testing to convert it to use bus_space were unanswered. Relnotes: yes Notes: svn path=/head/; revision=304502

Most calls to bus_alloc_resource() use "anywhere" as the range, with a given count. Migrate these to use the new bus_alloc_resource_anywhere() API. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D5370 Notes: svn path=/head/; revision=296137

These changes prevent sysctl(8) from returning proper output, such as: 1) no output from sysctl(8) 2) erroneously returning ENOMEM with tools like truss(1) or uname(1) truss: can not get etype: Cannot allocate memory Notes: svn path=/head/; revision=267985
2014-06-27Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky
there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

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

2008-09-08Pass 1 of mpsafetty-ifying si(4). It compiles and has basic functionality,Peter Wemm
but needs a lot more work. In particular, it has no flow control and has a tendency to race when giving commands. It still uses Giant for the tty and driver lock, but this is a keep-it-simple feature for now. Some of the [temporary] proliferation of messages lines are way too long. Notes: svn path=/head/; revision=182871
2008-06-09Remove sicontrol(8)'s "ttystat".Ed Schouten
In the FreeBSD base system, there are only two utilities that use struct tty, namely pstat and sicontrol. The sicontrol utility calls the TCSI_TTY ioctl(), which copies struct tty back to userspace. sicontrol should not have this functionality. The same data is already provided by pstat. If we really want to be able to export these numbers through a file descriptor to userspace, we can export struct xtty, which should provide a better abstraction. The ttystat option was only used as a debugging aid. This makes sicontrol compile in the mpsafetty branch. Reviewed by: peter Approved by: philip (mentor) Notes: svn path=/head/; revision=179668
