Description:
|
||||
This file allows to control the input triggers that
|
||||
turn on the keyboard backlight illumination that is
|
||||
disabled because of inactivity.
|
||||
Read the file to see the triggers available. The ones
|
||||
enabled are preceded by '+', those disabled by '-'.
|
||||
|
||||
To enable a trigger, write its name preceded by '+' to
|
||||
this file. To disable a trigger, write its name preceded
|
||||
by '-' instead.
|
||||
|
||||
For example, to enable the keyboard as trigger run:
|
||||
echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
|
||||
To disable it:
|
||||
echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
|
||||
|
||||
Note that not all the available triggers can be configured.

Description:
|
||||
This file allows to specify the interval after which the
|
||||
keyboard illumination is disabled because of inactivity.
|
||||
The timeouts are expressed in seconds, minutes, hours and
|
||||
days, for which the symbols are 's', 'm', 'h' and 'd'
|
||||
respectively.
|
||||
|
||||
To configure the timeout, write to this file a value along
|
||||
with any the above units. If no unit is specified, the value
|
||||
is assumed to be expressed in seconds.
|
||||
|
||||
For example, to set the timeout to 10 minutes run:
|
||||
echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
|
||||
|
||||
Note that when this file is read, the returned value might be
|
||||
expressed in a different unit than the one used when the timeout
|
||||
was set.
|
||||
|
||||
Also note that only some timeouts are supported and that
|
||||
some systems might fall back to a specific timeout in case
|
||||
an invalid timeout is written to this file.

* QEMU Firmware Configuration bindings for ARM
|
||||
|
||||
QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
|
||||
provide the following Firmware Configuration interface on the "virt" machine
|
||||
type:
|
||||
|
||||
- A write-only, 16-bit wide selector (or control) register,
|
||||
- a read-write, 64-bit wide data register.
|
||||
|
||||
QEMU exposes the control and data register to ARM guests as memory mapped
|
||||
registers; their location is communicated to the guest's UEFI firmware in the
|
||||
DTB that QEMU places at the bottom of the guest's DRAM.
|
||||
|
||||
The guest writes a selector value (a key) to the selector register, and then
|
||||
can read the corresponding data (produced by QEMU) via the data register. If
|
||||
the selected entry is writable, the guest can rewrite it through the data
|
||||
register.
|
||||
|
||||
The selector register takes keys in big endian byte order.
|
||||
|
||||
The data register allows accesses with 8, 16, 32 and 64-bit width (only at
|
||||
offset 0 of the register). Accesses larger than a byte are interpreted as
|
||||
arrays, bundled together only for better performance. The bytes constituting
|
||||
such a word, in increasing address order, correspond to the bytes that would
|
||||
have been transferred by byte-wide accesses in chronological order.
|
||||
|
||||
The interface allows guest firmware to download various parameters and blobs
|
||||
that affect how the firmware works and what tables it installs for the guest
|
||||
OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and
|
||||
initrd images for direct kernel booting, virtual machine UUID, SMP information,
|
||||
virtual NUMA topology, and so on.
|
||||
|
||||
The authoritative registry of the valid selector values and their meanings is
|
||||
the QEMU source code; the structure of the data blobs corresponding to the
|
||||
individual key values is also defined in the QEMU source code.
|
||||
|
||||
The presence of the registers can be verified by selecting the "signature" blob
|
||||
with key 0x0000, and reading four bytes from the data register. The returned
|
||||
signature is "QEMU".
|
||||
|
||||
The outermost protocol (involving the write / read sequences of the control and
|
||||
data registers) is expected to be versioned, and/or described by feature bits.
|
||||
The interface revision / feature bitmap can be retrieved with key 0x0001. The
|
||||
blob to be read from the data register has size 4, and it is to be interpreted
|
||||
as a uint32_t value in little endian byte order. The current value
|
||||
(corresponding to the above outer protocol) is zero.
|
||||
|
||||
The guest kernel is not expected to use these registers (although it is
|
||||
certainly allowed to); the device tree bindings are documented here because
|
||||
this is where device tree bindings reside in general.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: "qemu,fw-cfg-mmio".
|
||||
|
||||
- reg: the MMIO region used by the device.
|
||||
* Bytes 0x0 to 0x7 cover the data register.
|
||||
* Bytes 0x8 to 0x9 cover the selector register.
|
||||
* Further registers may be appended to the region in case of future interface
|
||||
revisions / feature bits.
|
||||
|
||||
Example:
|
||||
|
||||
/ {
|
||||
#size-cells = <0x2>;
|
||||
#address-cells = <0x2>;

* See note at ARMv7 ARM B1.14.4 (TL;DR: S/W ops are not easily virtualized).
|

*
|

* Main problems:
|
||||
* - S/W ops are local to a CPU (not broadcast)
|
||||
* - We have line migration behind our back (speculation)
|
||||
* - System caches don't support S/W at all (damn!)
|
||||
*
|
||||
* In the face of the above, the best we can do is to try and convert
|
||||
* S/W ops to VA ops. Because the guest is not allowed to infer the
|
||||
* S/W to PA mapping, it can only use S/W to nuke the whole cache,
|
||||
* which is a rather good thing for us.
|
||||
*
|
||||
* Also, it is only used when turning caches on/off ("The expected
|
||||
* usage of the cache maintenance instructions that operate by set/way
|
||||
* is associated with the cache maintenance instructions associated
|
||||
* with the powerdown and powerup of caches, if this is required by
|
||||
* the implementation.").
|
||||
*
|
||||
* We use the following policy:
|
||||
*
|
||||
* - If we trap a S/W operation, we enable VM trapping to detect
|
||||
* caches being turned on/off, and do a full clean.
|
||||
*
|
||||
* - We flush the caches on both caches being turned on and off.
|
||||
*
|
||||
* - Once the caches are enabled, we stop trapping VM ops.
