* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-1/+2
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
* kbd: merge linker set drivers into standard kbd driver listKyle Evans2019-12-262-44/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This leads to the revert of r355806; this reduces duplication in keyboard registration and driver switch lookup and leaves us with one authoritative source for currently registered drivers. The reduced duplication later is nice as we have more procedure involved in keyboard setup. keyboard_driver->flags is used to more quickly detect bogus adds/removes. From KPI consumers' perspective, nothing changes- kbd_add_driver of an already-registered driver will succeed, and a single kbd_delete_driver will later remove it as expected. In contrast to historical behavior, kbd_delete_driver on a driver registered via linker set will now actually de-register the driver so that it may not be used -- e.g. if kbdmux's MOD_LOAD handler fails somewhere. Detection for already-registered drivers in kbd_add_driver has improved, as the previous SLIST_NEXT(driver) != NULL check would not have caught a driver that's at the tail end. kbdinit is now called from cninit() rather than via SYSINIT so that keyboard drivers are available as early as console drivers. This is particularly important as cnprobe will, in both syscons and vt, attempt to do any early configuration of keyboard drivers built-in (see: kbd_configure).

* kbd: const'ify a couple of keyboard_driver fieldsKyle Evans2019-12-171-4/+9
| | | | | | | | | | Nothing modifies these things, but const'ify out of an abundance of caution. If we could const'ify the definition in each keyboard driver, I likely would- improper mutations here can lead to misbehavior or slightly more annoying to debug state.

* kbd: patch linker set methods, tooKyle Evans2019-12-161-0/+17
| | | | | | | | | | This is needed after r355796. Some double-registration of kbd drivers needs to be sorted out, then this sysinit will simply add these drivers into the normal list and kill off any other bits in the driver that are aware of the linker set, for simplicity.

* kbd: remove kbdsw, store pointer to driver in each keyboard_tKyle Evans2019-12-162-92/+77
| | | | | | | | | | | | | | | | | | The previous implementation relied on a kbdsw array that mirrored the global keyboards array. This is fine, but also requires extra locking consideration when accessing to ensure that it's not being resized as new keyboards are added. The extra pointer costs little in a struct that there are relatively few of on any given system, and simplifies locking requirements ever-so-slightly as we only need to consider the locking requirements of whichever method is being invoked. __FreeBSD_version is bumped as any kbd modules will need rebuilt following this change.

* kbd: drop _KERNEL #ifdef in kbdreg.hKyle Evans2019-12-151-4/+0
| | | | | | | | | | This #ifdef is misleading as there are actually no user-serviceable parts inside and, as far as I can tell, there is no pollution leading from userland to this header. Furthermore, it becomes a slight nuisance when attempting to move things around in this header. Notes: svn path=/head/; revision=355769
* evdev: Remove evdev.ko linkage dependency on kbd driverVladimir Kondratyev2018-08-132-0/+43
| | | | | | | | | | | | | | | | | | Move evdev_ev_kbd_event() helper from evdev to kbd.c as otherwise evdev unconditionally requires all keyboard and console stuff to be compiled into the kernel. This dependency happens as evdev_ev_kbd_event() helper references kbdsw global variable defined in kbd.c through use of kbdd_ioctl() macro. While here make all keyboard drivers respect evdev_rcpt_mask while setting typematic rate and LEDs with evdev interface.

| | | | | | | | | | | | | | | | | | Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197 Notes: svn path=/head/; revision=328218

| | | | | | | | | | | | | | Focus on code where we are doing multiplications within malloc(9). None of these is likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values. Notes: svn path=/head/; revision=327949

* Replace all calls to minor() with dev2unit().Ed Schouten2008-09-271-2/+2
| | | | | | | | | | | | | | | | | | 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. Reviewed by: kib Notes: svn path=/head/; revision=183397

| | | | | | | | | | | | | | | | | | | | | | | By default syscons(4) will look for the kbdmux(4) keyboard first, and then, if not found, look for any keyboard. Current kbd code is modified so if kbdmux(4) is the current keyboard, all new keyboards are automatically added to the kbdmux(4). Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at the loader prompt, or at runtime, by kldload'ing the kbdmux module and releasing current active keyboard. If, for whatever reason, kbdmux(4) is not required/desired then just do not load it and everything should work as before.

* - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) sourceMarius Strobl2005-06-104-2795/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
