First of all. T3Q is a fucking slut whore. Next, Core 2.0 optimizations

Browse Source 
* 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

NTFS3
=====
Summary and Features
====================
NTFS3 is fully functional NTFS Read-Write driver. The driver works with
NTFS versions up to 3.1, normal/compressed/sparse files
and journal replaying. File system type to use on mount is 'ntfs3'.
NTFS3 is fully functional NTFS Read-Write driver. The driver works with NTFS
versions up to 3.1. File system type to use on mount is *ntfs3*.
- This driver implements NTFS read/write support for normal, sparse and
compressed files.
- Supports native journal replaying;
- Supports extended attributes
Predefined extended attributes:
- 'system.ntfs_security' gets/sets security
descriptor (SECURITY_DESCRIPTOR_RELATIVE)
- 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.
Note: applied to empty files, this allows to switch type between
sparse(0x200), compressed(0x800) and normal;
- Supports native journal replaying.
- Supports NFS export of mounted NTFS volumes.
- Supports extended attributes. Predefined extended attributes:
- *system.ntfs_security* gets/sets security
Descriptor: SECURITY_DESCRIPTOR_RELATIVE
- *system.ntfs_attrib* gets/sets ntfs file/dir attributes.
Note: Applied to empty files, this allows to switch type between
sparse(0x200), compressed(0x800) and normal.
Mount Options
=============
The list below describes mount options supported by NTFS3 driver in addition to
generic ones.
generic ones. You can use every mount option with **no** option. If it is in
this table marked with no it means default is without **no**.
===============================================================================
.. flat-table::
:widths: 1 5
:fill-cells:
nls=name This option informs the driver how to interpret path
strings and translate them to Unicode and back. If
this option is not set, the default codepage will be
used (CONFIG_NLS_DEFAULT).
Examples:
'nls=utf8'
* - iocharset=name
- This option informs the driver how to interpret path strings and
translate them to Unicode and back. If this option is not set, the
default codepage will be used (CONFIG_NLS_DEFAULT).
uid=
gid=
umask= Controls the default permissions for files/directories created
after the NTFS volume is mounted.
Example: iocharset=utf8
fmask=
dmask= Instead of specifying umask which applies both to
files and directories, fmask applies only to files and
dmask only to directories.
* - uid=
- :rspan:`1`
* - gid=
nohidden Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)
attribute will not be shown under Linux.
* - umask=
- Controls the default permissions for files/directories created after
the NTFS volume is mounted.
sys_immutable Files with the Windows-specific SYSTEM
(FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system
immutable files.
* - dmask=
- :rspan:`1` Instead of specifying umask which applies both to files and
directories, fmask applies only to files and dmask only to directories.
* - fmask=
discard Enable support of the TRIM command for improved performance
on delete operations, which is recommended for use with the
solid-state drives (SSD).
* - noacsrules
- "No access rules" mount option sets access rights for files/folders to
777 and owner/group to root. This mount option absorbs all other
permissions.
force Forces the driver to mount partitions even if 'dirty' flag
(volume dirty) is set. Not recommended for use.
- Permissions change for files/folders will be reported as successful,
but they will remain 777.
sparse Create new files as "sparse".
- Owner/group change will be reported as successful, butthey will stay
as root.
showmeta Use this parameter to show all meta-files (System Files) on
a mounted NTFS partition.
By default, all meta-files are hidden.
* - nohidden
- Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute
will not be shown under Linux.
prealloc Preallocate space for files excessively when file size is
increasing on writes. Decreases fragmentation in case of
parallel write operations to different files.
* - sys_immutable
- Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute
will be marked as system immutable files.
no_acs_rules "No access rules" mount option sets access rights for
files/folders to 777 and owner/group to root. This mount
option absorbs all other permissions:
- permissions change for files/folders will be reported
as successful, but they will remain 777;
- owner/group change will be reported as successful, but
they will stay as root
* - discard
- Enable support of the TRIM command for improved performance on delete
operations, which is recommended for use with the solid-state drives
(SSD).
acl Support POSIX ACLs (Access Control Lists). Effective if
supported by Kernel. Not to be confused with NTFS ACLs.
The option specified as acl enables support for POSIX ACLs.
* - force
- Forces the driver to mount partitions even if volume is marked dirty.
Not recommended for use.
noatime All files and directories will not update their last access
time attribute if a partition is mounted with this parameter.
This option can speed up file system operation.
* - sparse
- Create new files as sparse.
===============================================================================
* - showmeta
- Use this parameter to show all meta-files (System Files) on a mounted
NTFS partition. By default, all meta-files are hidden.
ToDo list
* - prealloc
- Preallocate space for files excessively when file size is increasing on
writes. Decreases fragmentation in case of parallel write operations to
different files.
* - acl
- Support POSIX ACLs (Access Control Lists). Effective if supported by
Kernel. Not to be confused with NTFS ACLs. The option specified as acl
enables support for POSIX ACLs.
Todo list
=========
- Full journaling support (currently journal replaying is supported) over JBD.
- Full journaling support over JBD. Currently journal replaying is supported
which is not necessarily as effectice as JBD would be.

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.
Various Family 17h and 18h CPUs report voltage and current telemetry
information. The following attributes may be reported.
Attribute Label Description
=============== ======= ================
in0_input Vcore Core voltage
in1_input Vsoc SoC voltage
curr1_input Icore Core current
curr2_input Isoc SoC current
=============== ======= ================
Current values are raw (unscaled) as reported by the CPU. Core current is
reported as multiples of 1A / LSB. SoC is reported as multiples of 0.25A
/ LSB. The real current is board specific. Reported currents should be seen
as rough guidance, and should be scaled using sensors3.conf as appropriate
for a given board.
