telemetry driver from these optional resources, so that telemetry driver
has dependency only on the necessary ACPI resources.

We use a union for napi_id and send_cpu, this is ok for most of the
cases except when we want to support busy polling for tun which needs
napi_id to be stored and passed to socket during tun_net_xmit(). In
this case, napi_id was overridden with sender_cpu before tun_net_xmit()
was called if XPS was

Hi all:
This series try to add net device rx busy polling support in
vhost_net. This is done through:
- adding socket rx busy polling support for tun/macvtap by marking
napi_id.
- vhost_net will try to find the net device through napi_id and do
busy polling if possible.
TCP_RR tests on two m
This patch factors out core logic of busy polling to
sk_busy_loop_once() in order to be reused by other modules.

Debugging messages are not necessary after all of the
possible hardware failures that never occur.
Instead, this code can simply return 0.
This code also doesn't need to print in the success case.
tsc_init() already prints the TSC frequency,
and apic=debug is available if anybody

Remove the irqoff/irqon around MSR-based TSC enumeration,
as it is not necessary.
Also rename: try_msr_calibrate_tsc() to cpu_khz_from_msr(),
as that better describes what the routine does.

tsc_msr is used to quickly and reliably
enumerate the CPU/TSC frequencies at boot time
For the Intel Atom Architecture.
Extend tsc_msr to include recent Intel Core Architecture.
As this code discovers BCLK, it also sets lapic_timer_frequency,
which allows LAPIC timer calibration
From: Len Brown
Atom processors use a 19.2 MHz crystal oscillator.
Early processors generate 100 MHz via 19.2 MHz * 26 / 5 = 99.84 MHz.
Later preocessor generate 100 MHz via 19.2 MHz * 125 / 24 = 100 MHz.
Update the Silvermont-based tables accordingly,
matching the Software Developers Manual.
From: Bin Gao
Hard code the BXT crystal clock (aka ART - Always Running Timer)
to 19.200 MHz, and use CPUID leaf 0x15 to determine the BXT TSC frequency.
Use tsc_khz to sanity check BXT cpu_khz,

Skylake CPU base-frequency and TSC frequency may differ

Enumerate CPU and TSC frequencies separately, allowing

The existing CPU frequency calibration mechanism is unchanged.
However, CPUID extensions are preferred, when available.

cpu_khz and tsc_khz initialization can be unreliable and expensive.
They are initialized in tsc_init()/native_calibrate_tsc(), which prints:

native_calibrate_cpu() first tries quick_pit_calibrate(),
which can take over 50.0M cycles to succ
