For now assume 150 MByte in /boot/ and 200 in /lib/modules/ will suffice; how

On many commodity Linux distributions this will take care of everything

required to boot your kernel. You might want to ensure that's the case by

checking if your boot loader's configuration was updated; furthermore ensure
|

an initramfs (also known as initrd) exists, which on many distributions can be

achieved by running ``ls -l /boot/init*$(make -s kernelrelease)*``. Those

steps are recommended, as there are quite a few Linux distribution where above

command is insufficient:
|

The second command ideally will take care of three steps required at this
|

point: copying the kernel's image to /boot/, generating an initramfs, and
|

adding an entry for both to the boot loader's configuration.
|
||||
|
||||
* On Arch Linux, its derivatives, many immutable Linux distributions, and a
|

few others the above command does nothing at, as they lack 'installkernel'

executable.
|
||||
Sadly some distributions (among them Arch Linux, its derivatives, and many
|
||||
immutable Linux distributions) will perform none or only some of those tasks.
|
||||
You therefore want to check if all of them were taken care of and manually
|
||||
perform those that were not. The reference section provides further details on
|
||||
that; your distribution's documentation might help, too.
|
||||
|
||||
* Some distributions install the kernel, but don't add an entry for your
|
||||
kernel in your boot loader's configuration -- the kernel thus won't show up

in the boot menu.

||||
* Some distributions add a boot loader menu entry, but don't create an

initramfs on installation -- in that case your kernel most likely will be

What you need to do after executing the command in the step-by-step guide
|

depends on the existence and the implementation of an ``installkernel``
|

executable. Many commodity Linux distributions ship such a kernel installer in
|

'/sbin/' that does everything needed, hence there is nothing left for you

depends on the existence and the implementation of ``/sbin/installkernel``
|

executable on your distribution.
|
||||
|
||||
If ``installkernel`` is found, the kernel's build system will delegate the
|
||||
actual installation of your kernel's image and related files to this executable.
|
||||
On almost all Linux distributions it will store the image as '/boot/vmlinuz-
|
||||
<kernelrelease identifier>' and put a 'System.map-<kernelrelease
|
||||
identifier>' alongside it. Your kernel will thus be installed in parallel to any
|
||||
existing ones, unless you already have one with exactly the same release name.
|
||||
If installkernel is found, the kernel's build system will delegate the actual
|
||||
installation of your kernel image to this executable, which then performs some
|
||||
or all of these tasks:
|
||||
|
||||
Installkernel on many distributions will afterwards generate an 'initramfs'
|
||||
(often also called 'initrd'), which commodity distributions rely on for booting;
|
||||
hence be sure to keep the order of the two make targets used in the step-by-step
|
||||
guide, as things will go sideways if you install your kernel's image before its
|
||||
modules. Often installkernel will then add your kernel to the bootloader
|
||||
configuration, too. You have to take care of one or both of these tasks
|
||||
yourself, if your distributions installkernel doesn't handle them.
|
||||
* On almost all Linux distributions installkernel will store your kernel's
|
||||
image in /boot/, usually as '/boot/vmlinuz-<kernelrelease_id>'; often it will
|
||||
put a 'System.map-<kernelrelease_id>' alongside it.
|
||||
|
||||
A few distributions like Arch Linux and its derivatives totally lack an
|
||||
installkernel executable. On those just install the modules using the kernel's
|
||||
build system and then install the image and the System.map file manually::
|
||||
* On most distributions installkernel will then generate an 'initramfs'
|
||||
(sometimes also called 'initrd'), which usually are stored as
|
||||
'/boot/initramfs-<kernelrelease_id>.img' or
|
||||
'/boot/initrd-<kernelrelease_id>'. Commodity distributions rely on this file
|
||||
for booting, hence ensure to execute the make target 'modules_install' first,
|
||||
as your distribution's initramfs generator otherwise will be unable to find
|
||||
the modules that go into the image.
|
||||
|
||||
* On some distributions installkernel will then add an entry for your kernel
|
||||
to your bootloader's configuration.
|
||||
|
||||
You have to take care of some or all of the tasks yourself, if your
|
||||
distribution lacks a installkernel script or does only handle part of them.
|
||||
Consult the distribution's documentation for details. If in doubt, install the
|
||||
kernel manually::
|
||||
|
||||
sudo make modules_install
|
||||
sudo install -m 0600 $(make -s image_name) /boot/vmlinuz-$(make -s kernelrelease)
|
||||
sudo install -m 0600 System.map /boot/System.map-$(make -s kernelrelease)
|
||||
|
||||
If your distribution boots with the help of an initramfs, now generate one for

your kernel using the tools your distribution provides for this process.

Honeywell pressure sensor of model mprls0025pa.

This sensor has an I2C and SPI interface. Only the I2C interface is

implemented.
|

This sensor has an I2C and SPI interface.
|
||||
|
||||
There are many models with different pressure ranges available. The vendor
|
||||
calls them "mpr series". All of them have the identical programming model and
|
||||
differ in the pressure range, unit and transfer function.
|
||||
|
||||
To support different models one need to specify the pressure range as well as
|
||||
the transfer function. Pressure range needs to be converted from its unit to
|
||||
pascal.
|
||||
To support different models one need to specify its pressure triplet as well
|
||||
as the transfer function.
|
||||
|
||||
For custom silicon chips not covered by the Honeywell MPR series datasheet,
|
||||
the pressure values can be specified manually via honeywell,pmin-pascal and
|
||||
honeywell,pmax-pascal.
|
||||
The minimal range value stands for the minimum pressure and the maximum value
|
||||
also for the maximum pressure with linear relation inside the range.
|
||||
|
||||
The transfer function defines the ranges of numerical values delivered by the

Abracon ABX80X I2C ultra low power RTC/Alarm chip
|
||||
|
||||
The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
|
||||
ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
|
||||
is the superset of ab180x.
|
||||
|
||||
Required properties:
|
||||
|
||||
- "compatible": should one of:
|
||||
"abracon,abx80x"
|
||||
"abracon,ab0801"
|
||||
"abracon,ab0803"
|

|
||||
"abracon,ab1804"
|
||||
"abracon,ab1805"
|
||||
"microcrystal,rv1805"
|
||||
Using "abracon,abx80x" will enable chip autodetection.
|
||||
- "reg": I2C bus address of the device
|
||||
|
||||
Optional properties:
|
||||
|
||||
The abx804 and abx805 have a trickle charger that is able to charge the
|
||||
connected battery or supercap. Both the following properties have to be defined
|
||||
and valid to enable charging:
|
||||
|
||||
- "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
|
||||
- "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
|
||||
resistor, the other values are in kOhm.
