The CVE system as used for Linux today is unfit for purpose tbh.
these things still need reboots unfortunately
to my knowledge CUDA 12.5 is the newest CUDA that works on Xavier
bring back n-gate
nested virt with kernel-irqchip=off
@benpye it's pretty much generalised. an MMIO vmexit ends up overall being ~10x more expensive versus KVM
@agowa338 @pid_eins and they have/had things like display properties being an XML inside of the DSDT but that's a story for another day

@agowa338 @pid_eins they are ACPI but very Qualcomm-flavored and incompatible with Linux.

Some couple catches:

- The ACPI tables in firmware are incomplete. Qualcomm has supplemental ACPI table overlays shipped inside of their Windows driver packages.

And drivers have an ACPI table parser inside for _that_.

As far as I remember, that's a hack that they made when they exceeded 32k functions in the DSDT which made Windows mad.

- Qualcomm relies on a PEP driver instead of ACPI power management

@cb @sstephenson Gallium... has a sizeable impedance mismatch. And Vulkan does too....
@sstephenson so you'd need to find some way around that
