- Defining CLOCKS_PER_SEC = 100, instead of 60.
This define is here for legacy reasons, use sysconf(_SC_CLK_TCK) to
retrieve the actual number of clock tick per second of the system in
new code.
- Moving stime prototype to minix/sysutil.h

Also removing lseek64, pread64, pwrite64.
Those functions have lost their "raison d'être", when off_t switched to
64bits.

This allows us to write things like this:
message m;
m.m_notify.interrupts = new_value;
or
message *mp;
mp->m_notify.interrupts = new_value;
The shorthands macro have been adapted for the new scheme, and will be
kept as long as we have generic messages being used.
Change-Id: Icfd02b5f126892b1d5d2cebe8c8fb02b180000f7
Fix a bug where a filesystem label could overflow the reserved buffer.
This was already possible with 32 bits values, but is more proeminent
with dev_t being 64 bits.

This patch adds compile-time check for each message type to ensure the
size is within the IPC assumptions.
This will allow messages specific to a protocol to use from now on the
proper types for each fields, while preventing from any unsuspected
side effect when updating type definitions.

- redo call tables in both servers;
- remove param.h namespace pollution in the servers;
- make brk(2) go to VM directly, rather than through PM;
- remove obsolete BRK, UTIME, and WAIT calls;
- clean up path copying routine in VFS;
- move remaining system calls from libminlib to libc;
- correct some errno-related mistakes in libc routines.

These calls are sent to VFS, and thus should be prefixed with VFS_.
Clean up the protocol and PM's main function a bit.
Since the protocol is substantially big and different from normal VFS
requests, this protocol retains its own numbering range for now.
Change-Id: Ia62104b5c5c929ed787144816d2e4cc70bed3b0b
The getsysinfo(2), getrusage(2), and svrctl(2) calls used the same
call number to different services. Since we want to give each service
its own call number ranges, this is no longer tenable. This patch
introduces per-service call numbers for these calls.
Note that the remainder of the COMMON_ range is left intact, as these
the remaining requests in it are processed by SEF and thus server-
agnostic. The range should really be prefixed with SEF_ now.
Change-Id: I80d728bbeb98227359c525494c433965b40fefc3
- move system calls for use by services from libminlib into libsys;
- move srv_fork(2) and srv_kill(2) from RS and into libsys;
- replace getprocnr(2) with sef_self(3);
- rename previous getnprocnr(2) to getprocnr(2);
- clean up getepinfo(2);
- change all libsys calls that used _syscall to use _taskcall, so as
to avoid going through errno to pass errors; this is already how
most calls work anyway, and many of the calls previously using
_syscall were already assumed to return the actual error;
- initialize request messages to zero, for future compatibility
(note that this does not include PCI calls, which are in need of a
much bigger overhaul, nor kernel calls);
- clean up more of dead DS code as a side effect.

NetBSD libc implements these as wrappers around setitimer(2),
sigsuspend(2), and getrusage(2), respectively.

. alignment of the struct has become 8 bytes instead of 4
. remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE

. new test for dirent contents filled by getdents()
Change-Id: I1459755c7ba5e5d1c9396d3a587ce6e63ddc283e
- all TTY-related exceptions have now been merged into the regular
code paths, allowing non-TTY drivers to expose TTY-like devices;
- as part of this, CTTY_MAJOR is now fully managed by VFS instead of
being an ugly stepchild of the TTY driver;
- device styles have become completely obsolete, support for them has
been removed throughout the system; same for device flags, which had
already become useless a while ago;
- device map open/close and I/O function pointers have lost their use,
thus finally making the VFS device code actually readable;
- the device-unrelated pm_setsid has been moved to misc.c;
- some other small cleanup-related changes.

This single function allows copying file descriptors from and to
processes, and closing a previously copied remote file descriptor.
This function replaces the five FD-related UDS backcalls. While it
limits the total number of in-flight file descriptors to OPEN_MAX,
this change greatly improves crash recovery support of UDS, since all
in-flight file descriptors will be closed instead of keeping them
open indefinitely (causing VFS to crash on system shutdown). With the
new copyfd call, UDS becomes simpler, and the concept of filps is no
longer exposed outside of VFS.
This patch also moves the checkperms(2) stub into libminlib, thus
fully abstracting away message details of VFS communication from UDS.
Change-Id: Idd32ad390a566143c8ef66955e5ae2c221cff966
- remove non-PCI support, since all supported platforms with at_wini
devices also have PCI support by now;
- correspondingly, stop using information from the BIOS altogether;
- limit each driver instance to one controller, to be in line with
the general MINIX3 one-instance-per-controller driver model; this
limits the number of disks per at_wini instance to four;
- go through the controllers by the order of their occurrence in the
PCI table, thus removing the exception for compatibility devices;
- let the second at_wini instance shut down silently if there is only
one IDE controller;
- clean up some extra code we don't need anymore, and resolve some
WARNS=5 level warnings.
Overall, these changes should simplify automatic loading of the right
disk drivers at boot time in the future.
Change-Id: Ia64d08cfbeb9916abd68c9c2941baeb87d02a806
- change "vid/did" to "vid:did", old form still supported for now;
- allow "vid:did/subvid:subdid" specification in system.conf, in
which case a device will be visible to a driver if the subsystem
VID/DID also match.

This commit separates the low-level keyboard driver from TTY, putting
it in a separate driver (PCKBD). The commit also separates management
of raw input devices from TTY, and puts it in a separate server
(INPUT). All keyboard and mouse input from hardware is sent by drivers
to the INPUT server, which either sends it to a process that has
opened a raw input device, or otherwise forwards it to TTY for
standard processing.
Design by Dirk Vogt. Prototype by Uli Kastlunger.
Additional changes made to the prototype:
- the event communication is now based on USB HID codes; all input
drivers have to use USB codes to describe events;
- all TTY keymaps have been converted to USB format, with the effect
that a single keymap covers all keys; there is no (static) escaped
keymap anymore;
- further keymap tweaks now allow remapping of literally all keys;
- input device renumbering and protocol rewrite;
- INPUT server rewrite, with added support for cancel and select;
- PCKBD reimplementation, including PC/AT-to-USB translation;
- support for manipulating keyboard LEDs has been added;
- keyboard and mouse multiplexer devices have been added to INPUT,
primarily so that an X server need only open two devices;
- a new "libinputdriver" library abstracts away protocol details from
input drivers, and should be used by all future input drivers;
- both INPUT and PCKBD can be restarted;
- TTY is now scheduled by KERNEL, so that it won't be punished for
running a lot; without this, simply running "yes" on the console
kills the system;
- the KIOCBELL IOCTL has been moved to /dev/console;
- support for the SCANCODES termios setting has been removed;
- obsolete keymap compression has been removed;
- the obsolete Olivetti M24 keymap has been removed.

Most systems provide the full version number in the
'release' field and the kernel version in 'version'.
Minix used to split the full version number between
release and version which caused problems for pkgsrc
and other applications. This patch brings Minix's
uname in line with other systems such as NetBSD.
It also brings the getty banner in line with NetBSD.
Old Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3
version->2.1
machine->i686
New Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3.2.1
version->Minix 3.2.1 (GENERIC)
machine->i686

The set of processes to which a SIGKMESS signal is sent whenever new
diagnostics messages are added to the kernel's message buffer, is now
no longer hardcoded. Instead, processes can (un)register themselves
to receive such notifications, by means of sys_diagctl().
