- Your program uses data structures with pointer or long / unsigned long
types that interface with BPF helpers or context data structures. Access
into these structures is verified by the BPF verifier and may result
in verification failures if the native architecture is not aligned with
the BPF architecture, e.g. 64-bit. An example of this is

boot:
Same as mono. Used to be a separate clock which accounted
for the time spent in suspend while CLOCK_MONOTONIC did
not.
This is the boot clock (CLOCK_BOOTTIME) and is based on the
fast monotonic clock, but also accounts for time spent in
suspend. Since the clock access is designed for use in
tracing in the suspend path, some side effects are possible
if clock is accessed after the suspend time is accounted before
the fast mono clock is updated. In this case, the clock update
appears to happen slightly sooner than it normally would have.
Also on 32-bit systems, it's possible that the 64-bit boot offset
sees a partial update. These effects are rare and post
processing should be able to handle them. See comments in the
ktime_get_boot_fast_ns() function for more information.
To set a clock, simply echo the clock name into this file::

KVM implements the PSCI (Power State Coordination Interface)
specification in order to provide services such as CPU on/off, reset
and power-off to the guest.
The PSCI specification is regularly updated to provide new features,
and KVM implements these updates if they make sense from a virtualization
point of view.
This means that a guest booted on two different versions of KVM can
observe two different "firmware" revisions. This could cause issues if
a given guest is tied to a particular PSCI revision (unlikely), or if
a migration causes a different PSCI version to be exposed out of the
blue to an unsuspecting guest.
In order to remedy this situation, KVM exposes a set of "firmware
pseudo-registers" that can be manipulated using the GET/SET_ONE_REG
interface. These registers can be saved/restored by userspace, and set
to a convenient value if required.
The following register is defined:
* KVM_REG_ARM_PSCI_VERSION:
- Only valid if the vcpu has the KVM_ARM_VCPU_PSCI_0_2 feature set
(and thus has already been initialized)
- Returns the current PSCI version on GET_ONE_REG (defaulting to the
highest PSCI version implemented by KVM and compatible with v0.2)
- Allows any PSCI version implemented by KVM and compatible with
v0.2 to be set with SET_ONE_REG
- Affects the whole VM (even if the register view is per-vcpu)
