Currently, requesting kernel FPU access doesn't distinguish which parts of
the extended ("FPU") state are needed. This is nice for simplicity, but
there are a few cases in which it's suboptimal:
- The vast majority of in-kernel FPU users want XMM/YMM/ZMM state but do
not use legacy 387 state.
The default kernel_fpu_begin() doesn't work on systems that support XMM but
haven't yet enabled OSFXSR. This causes crashes when _mmx_memcpy() is
called too early.
Fix it by using kernel_fpu_begin(KFPU_MMX) explicitly. This should also be
faster, since it skips both the reasonably fast LDMXCSR a
The remaining callers of kernel_fpu_begin() in 64-bit kernels don't use 387
instructions, so there's no need to sanitize FCW. Skip it to get the
performance we lost back.

[AMD Public Use]
Thanks Setphen. Please check attached V2 patch.
(If you can share the config file to me, I can do the test in my side)
Best Regards,

All IRQs that can be used to wake up the system must be routed through
r_intc, so they are visible to firmware while the system is suspended.
In addition to the external NMI input, which is already routed through
r_intc, these include PIO and R_PIO (gpio-keys), the LRADC, and the RTC.

The R_INTC block controls more than just the NMI, and it is a different
hardware block than the NMI INTC found in some other Allwinner SoCs, so
the label "nmi_intc" is inaccurate. Name it "r_intc" to match the
compatible and to match the few references in the vendor documentation.

The binding of R_INTC was updated to allow specifying interrupts other
than the external NMI, since routing those interrupts through the R_INTC
driver allows using them for wakeup.
Update the device trees to use the new binding.

The R_INTC in the A31 and newer sun8i/sun50i SoCs is more similar to the
original sun4i interrupt controller than the sun7i/sun9i NMI controller.
It is used for two distinct purposes:
- To control the trigger, latch, and mask for the NMI input pin
- To provide the interrupt input for the ARISC co
The H3 and H5 SoCs have an additional interrupt controller in the RTC
power domain that can be used to enable wakeup for certain IRQs.
Add a node for it.

The R_INTC in the A31 and newer sun8i/sun50i SoCs has additional
functionality compared to the sun7i/sun9i NMI controller. Among other
things, it multiplexes access to up to 128 interrupts corresponding to
(and in parallel to) the first 128 GIC SPIs. This means the NMI is no
longer the lowest-numbe

Allwinner sun6i/sun8i/sun50i SoCs (A31 and newer) have two interrupt

This serves two purposes. First, it lets power management firmware

The Allwinner H3 SoC contains an R_INTC that is, as far as we know,
compatible with the R_INTC present in other sun8i SoCs starting with
the A31. Since the R_INTC hardware is undocumented, introduce a new
compatible for the R_INTC variant in this SoC, in case there turns out
to be some difference.
The remote-endpoint may not be available if it is part of some
pluggable module. One such example would be an audio card, the
Codec endpoint will not be available until it is plugged in.
Hence drop 'remote-endpoint' as a required property.
