* NVME, SATA NAND Security added * Qortal Core exception fetcher is now redone. * Update DT overlays for firmware * Fix for bvb clockj settings * Fix for no audio for sissy desktop porn watchers -_- ( thanks crowetic for watching gay porn and reporting me that bug asshat ) * Normalize the fetch() stream while doing a peer to peer handshake for nodes * Fix for RNG token editing error while performing a SHA256 encryption * Now under voltage errors will blink red led constantly for 5 minutes then go solid. * Improve kernel thread scaling for Qortal 2.0 core * HDMI circuit is now enabled at power up instead. * Added KMS * Added line replication instead of interpolation for VC4 GPU resulting in slightly better frame rates * Fix for long and doubles * Backplane clock is now set at standard rate * Capped HVEC clocks * Add support for Creative Cinema webcam for donkers who like sharing dick pics. *looks at crowetic* * More scanline XGA modes for people who have weird ass monitors of all sorts. * TX/RX flow control support is now 100% stable. No lags over 1Gbps ethernet. ( Hello Qortal 3.0 ) * Using flush cache instead of fetch for QC 2.0 resulting in performance gains * VC4 clock is now enforced for desktop oriented images. * Ondemand governor now waits for 2 seconds instead of 0.5ms to scale down to the lowest safest clock freq preventing lags to the core. * Timeout of OC set at 35ms from 90ms resulting in way better clocks and sync for Qortal 2.0 core

Description
|
|
-----------
|
|
|
|
This driver permits reading of the internal temperature sensor of AMD
|
|
Family 10h/11h/12h/14h/15h/16h processors.
|
|
|
|
All these processors have a sensor, but on those for Socket F or AM2+,
|
|
the sensor may return inconsistent values (erratum 319). The driver
|
|
will refuse to load on these revisions unless you specify the "force=1"
|
|
module parameter.
|
|
|
|
Due to technical reasons, the driver can detect only the mainboard's
|
|
socket type, not the processor's actual capabilities. Therefore, if you
|
|
are using an AM3 processor on an AM2+ mainboard, you can safely use the
|
|
"force=1" parameter.
|
|
|
|
For CPUs older than Family 17h, there is one temperature measurement value,
|
|
available as temp1_input in sysfs. It is measured in degrees Celsius with a
|
|
resolution of 1/8th degree. Please note that it is defined as a relative
|
|
value; to quote the AMD manual::
|
|
|
|
Tctl is the processor temperature control value, used by the platform to
|
|
control cooling systems. Tctl is a non-physical temperature on an
|
|
arbitrary scale measured in degrees. It does _not_ represent an actual
|
|
physical temperature like die or case temperature. Instead, it specifies
|
|
the processor temperature relative to the point at which the system must
|
|
supply the maximum cooling for the processor's specified maximum case
|
|
temperature and maximum thermal power dissipation.
|
|
|
|
The maximum value for Tctl is available in the file temp1_max.
|
|
|
|
If the BIOS has enabled hardware temperature control, the threshold at
|
|
which the processor will throttle itself to avoid damage is available in
|
|
temp1_crit and temp1_crit_hyst.
|
|
|
|
On some AMD CPUs, there is a difference between the die temperature (Tdie) and
|
|
the reported temperature (Tctl). Tdie is the real measured temperature, and
|
|
Tctl is used for fan control. While Tctl is always available as temp1_input,
|
|
the driver exports Tdie temperature as temp2_input for those CPUs which support
|
|
it.
|
|
|
|
Models from 17h family report relative temperature, the driver aims to
|
|
compensate and report the real temperature.
|
|
|
|
On Family 17h and Family 18h CPUs, additional temperature sensors may report
|
|
Core Complex Die (CCD) temperatures. Up to 8 such temperatures are reported
|
|
as temp{3..10}_input, labeled Tccd{1..8}. Actual support depends on the CPU
|
|
variant.
