3d01d65ba0 config: add aarch64 clang for Ubuntu 18.04
Create distribution specific meson cross-file
arm64_armv8_linux_clang_ubuntu1804. The file is distribution specific
because it contains paths to headers and libs specific to the
distribution. The clang/LLVM toolchain does not provide its own c stdlib
so the paths must be supplied in some manner.

In the current version of meson, v0.47.1, the only place
where the paths can be specified is the cross-file. Other possibilities
do not work:
* setting CFLAGS, LDFLAGS only sets these for non-cross builds.
* setting -Dc_args, -Dc_link_args on the command line also only sets
these for non-cross builds. Support for specifying these for
cross builds was added in v0.51.0 [0].
* the cross-file can't be split into generic clang cross config and
distribution specific config. Support added in v0.52.0 [1].

e9b9739264 config: remap flags used for Arm platforms
RTE_ARCH_xx flags are used to distinguish platform architectures.
These flags can be used to pick different code paths for different
architectures at compile time.
For Arm platforms, there are 3 flags in use: RTE_ARCH_ARM,
RTE_ARCH_ARMv7 and RTE_ARCH_ARM64.
RTE_ARCH_ARM64 is for 64-bit aarch64 platforms,
and RTE_ARCH_ARM & RTE_ARCH_ARMv7 are for 32-bit platforms.
RTE_ARCH_ARMv7 is for ARMv7 platforms as its name suggested.

The issue is meaning of RTE_ARCH_ARM is not clear enough.
Because no info about platform word length is included in the name.
To make the flag names more clear, a naming scheme is proposed.

RTE_ARCH_ARM (all Arm platforms)
    |
    +----RTE_ARCH_32 (New. 32-bit platforms of all architectures)
    |        |
    |        +----RTE_ARCH_ARMv7 (ARMv7 platforms)
    |        |
    |        +----RTE_ARCH_ARMv8_AARCH32 (aarch32 state on aarch64 machine)
    |
    +----RTE_ARCH_64 (64-bit platforms of all architectures)
             |
             +----RTE_ARCH_ARM64 (64-bit Arm platforms)

RTE_ARCH_32 will be explicitly defined for 32-bit platforms.

To fit into the new naming scheme, current usage of RTE_ARCH_ARM in
project is mapped to (RTE_ARCH_ARM && RTE_ARCH_32).

Matching flags for other architectures are:
RTE_ARCH_X86
    |
    +----RTE_ARCH_32
    |        |
    |        +----RTE_ARCH_I686
    |        |
    |        +----RTE_ARCH_X86_X32
    |
    +----RTE_ARCH_64
             |
             +----RTE_ARCH_X86_64

RTE_ARCH_PPC_64 ---- RTE_ARCH_64

to save CPU cycles and power.

From a VM, when calling this API on aarch64, it may trap in and out to
release vCPUs whereas cause high exit latency. Since kernel 4.18.20 an
adaptive trapping mechanism is introduced to balance the latency and

7e2c3e17fe eal/arm64: add 128-bit atomic compare exchange
This patch adds the implementation of the 128-bit atomic compare
exchange API on aarch64. Using 64-bit 'ldxp/stxp' instructions
can perform this operation. Moreover, on the LSE atomic extension
accelerated platforms, it is implemented by 'casp' instructions for
better performance.

Since the '__ARM_FEATURE_ATOMICS' flag only supports GCC-9, this
patch adds a new config flag 'RTE_ARM_FEATURE_ATOMICS' to enable
the 'cas' version on older version compilers.
For octeontx2, we make sure that the lse (and other) extensions are
enabled even if the compiler does not know of the octeontx2 target
cpu.

Since direct x0 register used in the code and cas_op_name() and
rte_atomic128_cmp_exchange() is inline function, based on parent
function load, it may corrupt x0 register aka break aarch64 ABI.
Define CAS operations as rte_noinline functions to avoid an ABI
break [1].

e404de1305 config: disable armv8 crypto extension
Per armv8 crypto extension support, make build always enable it by default
as long as compiler supports the feature while meson build only enables it
for 'default' machine of generic armv8 architecture.

It is known that not all the armv8 platforms have the crypto extension. For
example, Mellanox BlueField has a variant which doesn't have it. If crypto
enabled binary runs on such a platform, rte_eal_init() fails.

'+crypto' flag currently implies only '+aes' and '+sha2' and enabling it
will generate the crypto instructions only when crypto intrinsics are used.
For the devices supporting 8.2 crypto or newer, compiler could generate
such instructions beyond intrinsics or asm code. For example, compiler can
generate 3-way exclusive OR instructions if sha3 is supported. However, it
has to be enabled by adding '+sha3' as of today.

In DPDK, armv8 cryptodev is the only one which requires the crypto support.
As it even uses external library of Marvell which is compiled out of DPDK
with crypto support and there's run-time check for required cpuflags,
crypto support can be disabled in DPDK.

380154406d build: use default flags for default Arm machine
When building for generic distribution we need a stable baseline
architecture, or depending on the build worker the result will vary.

Force the default flags if the user explicitly sets machine=default
at configuration time.

42c3cd0e6e meson: support Arm machine specific flags
Currently, RTE_* flags are set based on the implementer ID but there might
be some micro arch specific differences from the same vendor
eg. CACHE_LINESIZE. Add support to set micro arch specific flags.

3ce6474b22 build: improve pcap dependency handling
pcap has historically shipped a custom pcap-config binary tool which
does the job of pkg-config. It was never compatible with cross
compilation.
Meson uses it when using dependency(), which then means cross
compilation fails.
Set pcap-config to empty in the meson cross compilation files so
that Meson will not use it, and add a fallback in case
dependency() fails.
libpcap 1.9.0 finally ships a pkg-config file so everything will
work out of the box in the future.

d23e141ffa build: set RTE_ARCH_64 based on pointer size
Rather than relying on the target machine architecture, use the
size of a pointer from the compiler to determine if we are 64-bits
or not. This allows correct behaviour when you pass -m32 as a compile
option. It also allows us to use this value repeatedly throughout the
repo rather than continually testing for the sizeof(void*).

8a19276261 bus/dpaa2: fix default IOVA setting for meson builds
By default, the DPAA2_USE_PHYS_IOVA setting with the make build-system
is "y", which is overridden to "n" in the config file specifically for
the arm64-dpaa2-linuxapp-gcc builds. The lack of this setting in meson
builds causes issues for 32-bit build, as the alternative code paths
have compiler warnings e.g. for i686 builds. Therefore we should align
the meson and make settings, setting the value to "true" by default and
overriding it to "false" for dpaa2-specific builds.
