Hi William,

2021-08-14 03:36 (UTC+0000), William Tu:

I don't have a physical Windows testbed so I want to see if I can
get virtual nic working, in this case ENA driver on AWS.
The patch passes build on Windows, but I haven't tested loading
the ena driver.
I want to know if this is the right direction,
or whether I also need to change other places in ENA driver?

Cc'ing maintainers.

I copy some of the pthread code from
https://nachtimwald.com/2019/04/05/cross-platform-thread-wrapper/

We don't want to add more pthread shims, pthread.h in DPDK will go away.
Condition variable support should be added to the new threading API:

I suppose it can be done independently of the new threading API series.
When copying code to DPDK from elsewhere, please adapt its style to DPDK
conventions (e.g. `RTE_UNUSED(foo)` instead if `(void)foo`) and mind the
license if big pieces are copied verbatim (this is not the case here).

POSIX gettimeofday() should be replaced with standard C timespec_get().

Thanks.

This should be a series of two patches:
1) adding condition variable wrappers to EAL;
2) supporting net/ena for Windows.
