kernel to boot in a paravirtualized environment under the
Xen hypervisor.

depends on XEN_PV

help
Limit paravirtualized user domains to 512GB of RAM.
The Xen tools and crash dump analysis tools might not support
pv-domains with more than 512 GB of RAM. This option controls the
default setting of the kernel to use only up to 512 GB or more.
It is always possible to change the default via specifying the
boot parameter "xen_512gb_limit".

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