Description: This allows speakup to speak letters phoneticaly when arrowing through
a word letter by letter. This doesn't affect the spelling when typing
the characters. When cur_phonetic=1, speakup will speak characters
phoneticaly when arrowing over a letter. When cur_phonetic=0, speakup
will speak letters as normally.

Description:
The coreboot bus provides a variety of virtual devices used to
access data structures created by the Coreboot BIOS.

What: /sys/bus/coreboot/devices/cbmem-<id>
Date: August 2022
Contact: Jack Rosenthal <[email protected]>
Description:
CBMEM is a downwards-growing memory region created by Coreboot,
and contains tagged data structures to be shared with payloads
in the boot process and the OS. Each CBMEM entry is given a
directory in /sys/bus/coreboot/devices based on its id.
A list of ids known to Coreboot can be found in the coreboot
source tree at
``src/commonlib/bsd/include/commonlib/bsd/cbmem_id.h``.

What: /sys/bus/coreboot/devices/cbmem-<id>/address
Date: August 2022
Contact: Jack Rosenthal <[email protected]>
Description:
This is the pyhsical memory address that the CBMEM entry's data
begins at, in hexadecimal (e.g., ``0x76ffe000``).

Description:
This is the size of the CBMEM entry's data, in hexadecimal
(e.g., ``0x1234``).

What: /sys/bus/coreboot/devices/cbmem-<id>/mem
Date: August 2022
Contact: Jack Rosenthal <[email protected]>
Description:
A file exposing read/write access to the entry's data. Note
that this file does not support mmap(), as coreboot
does not guarantee that the data will be page-aligned.

The mode of this file is 0600. While there shouldn't be
anything security-sensitive contained in CBMEM, read access
requires root privileges given this is exposing a small subset
of physical memory.

What: /sys/bus/iio/devices/iio:deviceX/in_voltage-voltage_filter_mode_available
KernelVersion: 6.2
Contact: [email protected]
Description:
Reading returns a list with the possible filter modes.

* "sinc4" - Sinc 4. Excellent noise performance. Long
1st conversion time. No natural 50/60Hz rejection.

* "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion
time.

* "sinc3" - Sinc3. Moderate 1st conversion time.
Good noise performance.

* "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling
frequency of 50Hz, achieves simultaneous 50Hz and 60Hz
rejection.

* "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion
time. Best used with a sampling frequency of at least
216.19Hz.

* "sinc3+pf1" - Sinc3 + Post Filter 1. 53dB rejection @
50Hz, 58dB rejection @ 60Hz.

* "sinc3+pf2" - Sinc3 + Post Filter 2. 70dB rejection @
50Hz, 70dB rejection @ 60Hz.

* "sinc3+pf3" - Sinc3 + Post Filter 3. 99dB rejection @
50Hz, 103dB rejection @ 60Hz.

* "sinc3+pf4" - Sinc3 + Post Filter 4. 103dB rejection @
50Hz, 109dB rejection @ 60Hz.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY-voltageZ_filter_mode
KernelVersion: 6.2
Contact: [email protected]
Description:
Set the filter mode of the differential channel. When the filter
mode changes, the in_voltageY-voltageZ_sampling_frequency and
in_voltageY-voltageZ_sampling_frequency_available attributes
might also change to accommodate the new filter mode.
If the current sampling frequency is out of range for the new
filter mode, the sampling frequency will be changed to the
closest valid one.
