b058039a35 TTY: fix earlier PTY select "improvement"
It was just plain wrong.

e5cc85fdc4 Extend dupfrom(2) into copyfd(2)
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.

9e3e032c26 UDS: sendmsg/recvmsg fixes
- sendmsg: the accumulation of multiple in-flight file descriptors was
  already described in the comments; now the code actually does what
  the comments say :) -- also, added robustness in case of a failure;
- recvmsg: only create a socket rights message if there are file
  descriptors pending at all;
- recvmsg: copy back the control message length;
- recvmsg: use CMSG_SPACE instead of CMSG_LEN to compute sizes.

Not sure if all of this is now working according to specification,
but at least tmux seems to be happy with it.

6d466f941b at_wini: PCI-only now; one controller per instance
- 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.

6b3f4dc157 Input infrastructure, INPUT server, PCKBD driver
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.

ec2359d566 TTY: allow selecting on translated minors
Due to the existence of /dev/console and /dev/log, and the new
"console=" setting, it is now possible that a single non-PTY object
(e.g. serial) is accessible through two different minor numbers.  This
poses a problem when sending late select replies (CDEV_SEL2_REPLY),
because the object's minor number can not be used to identify the
device.  Since selecting on such objects through translated minor
numbers is actually required, we now save the minor number used to
initiate the select query in order to send a late reply.

The solution is suboptimal, as it is not possible to use two different
minors to select on the same object at once.  In the future, there
should be at least one select record for each minor that can be used
with each object.

3af30c2c60 ARM serial driver: Comment termios_baud_rate.
The B0-B115200 defines are flags, and not the actual speed they
represent.

This fixes an incoherency for B0 handling, and documents why it is
required to call the function again after changing the speed flag.

DFL_BAUD is set to one of the flag, so to translate it to an actual
speed, the function calls itself again, which will always be able to
finish without inducing another recursive call.

5e48dc3f40 TTY: skip /dev/log checks if console is serial
It is unclear why /dev/log has its own open/close rules, but those
rules conflict with serial console redirection.  This does not solve
the root of the problem, but it puts back in place more or less the
same workaround that was already in place before the TTY overhaul.

  "cum" fields;
- improved variable typing and function naming here and there;

597151d963 libchardriver: full API rewrite
The new API now covers the entire character driver protocol, while
hiding all the message details. It should therefore be used by all
new character drivers. All existing drivers that already made use of
libchardriver have been changed to use the new API.

As one of the most important API changes, support for scatter and
gather transfers has been removed, as several key drivers already
did not support this, and it could be supported at the safecopy
level instead (for a future readv/writev).

Additional changes include:

- respond to block device open requests to avoid hanging VFS threads;
- add support for sef_cancel.

field, which is an alias for BDEV_FLAGS. The contents of this field

preserved (not replaced!) by services that forward IOCTL requests,
and may be set to NONE for service-initiated IOCTL requests.

cb5e2921b3 i2c: increase read/write timeout
The sht21 temperature and humidity sensor holds the i2c bus while
an ADC conversion is in progress. For example, a temperature
measurement is requested, a read operation is started, and the
sht21 doesn't respond to the read request until the result of
the measurement is ready. The conversion time isn't constant.
On rare occations (one in hundreds of samples) the timeout in the
i2c driver expires returning an error.

The example code from Sensirion, the sht21's manufacturer, suggests
a bus timeout of 1 second to accommodate the sht21. This commit
increases the bus timeout to 1 second. The timeout is only reached
when chips do not respond normally, so the change doesn't affect the
performance of any other drivers.

75bd3009d3 libi2cdriver: add functions for IC register access
Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.

The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.

f0c391e09b virtio-net: acknowledge used features
According to the virtio specifications, the host present the supported
features to the guest, and the guest should answer woth the features it
supports. This allows the host to disable support for features that the
guest is not going to use.

Minix tells to the host it doesn't support any extended features, while
it uses at least VIRTIO_NET_F_MAC and VIRTIO_NET_F_CTRL_VQ. For the
latter it seems it only allocate the queue while not using it later.
However starting with QEMU 1.4.0, with multiqueue support added, the
control queue is not allocated on the host side if the guest doesn't
tell it supports this feature. This cause virtio-net to crash on the
Minix side.

This patch fixes that by correctly telling the features that are
used by the Minix guest for more than printing a debug message. This
fixes virtio-net on QEMU 1.4.x.

4593804bf0 kernel: add padconf kernel call
On the AM335X, writes to the padconf registers must be done in privileged
mode. To allow userspace drivers to dynamically change the padconf at
runtime, a kernel call has been added.

228e84ad2a i2c: general clean-up
Implement changes based on Kees comments on the code review:
	http://gerrit-minix.few.vu.nl/#/c/676/

Changes:
 - use spin API instead of micro_delay() for busy-wait loops.
 - use read16/write16/set16 from mmio.h to access I2C registers.
 - reduce the timeout for soft reset.
 - in read/write, don't mix variable declaration and initialization.
 - after transfer, wait for access ready instead of blindly delaying.
 - rename constants am335x, dm37xx to AM335X_I2C_BUS, DM37XX_I2C_BUS.
 - rename ADDRESS_MASK to MAX_I2C_SA_MASK for clairity.
 - rename omap_i2c_claim_bus() to omap_i2c_bus_is_free().

039c8db774 readclock.drv: add support for the TPS65950 RTC
On the BeagleBoard-xM, the RTC is located on the Power Management IC
(PMIC). To keep things consistent, access to the PMIC's RTC is done
through the readclock driver. The readclock driver forwards the request
on to the TPS65950 driver which does the work of manipulating the
registers on the chip.

09db2a8c67 readclock: add support for am335x RTC
Add support for getting/setting the am335x SoC's internal real
time clock. Also, allow the power off alarm to be set.

Make readclock an "always on" driver. This is needed for setting
power-off alarms whenever the power button is pressed on the BBB.

Replace the readclock.sh script & single run driver with a
readclock program that takes the same arguments and forwards
the requests on to the always up readclock driver.

437177b028 i2c: increase BUFLEN/CMDLEN to 128, add page flag.
128 byte reads are much more common than 32 byte reads. The message
passing + setup/teardown for a read is much more expensive, in terms
of time, than the reading itself. A slightly bigger struct is well
worth the time savings. This reduces read times for /dev/eeprom
from 57 seconds per 4KB to 14 seconds.

Additionally, make sending the page address in the eeprom driver
and utility optional. This can save a little time when reading
within the same page and allows support for smaller devices that
don't support pages (example: chips containing EDID).
