The brief status of Debian riscv porting --2022/10/22

Hi!

Thank you for sharing the porting status of RISCV64.

When I make this a Debian official port, I'm worried about what is a blocker.
Of course, there is a porting package coverage, but do you know what
the support status
such as infrastructure and others when it becomes an official port?
If possible, I would like to cooperate with this.

According to architecture requalification[0] and other
information[1][2], Buildd-DSA[3] and
porterbox seem to be major blockers. Are you or other member working on these?

Hi,

In the past two weeks, due to the atomic problem and the cargo build
dependency problem, the number of riscv64 built packages has been
maintained at about 15k[0], which is a little lower than before.
Because when is unknown the upstream of GCC will be able to merge
the patch of solving the atomic issue, and the porter sends the
patch to build the affected package.

Another thanks to pabs, we maybe have some work to do about
cross-build for Debian riscv64. But limited by personal experience,
I cannot evaluate these specific jobs. Here, I just grep the pabs's
wiki[1] here.

```
Make the port available for maintainers and users to cross-build packages to:

Add support to the binutils source package

Add libc6*-dev-$arch-cross, libc6*-$arch-cross and linux-libc-dev-$arch-cross
packages to the cross-toolchain-base (for ftp-master.d.o arches) or
cross-toolchain-base-ports (for ports.d.o arches) source packages

Add support to the current gcc-N source package

Add metapackages to the gcc-defaults source package

Add a crossbuild-essential-$arch metapackage to the build-essential
source package
```

I've tried building some of these packages and obviously need to add
riscv64 support (maybe with some help from the Debian toolchain folks for me).

Yeah, It seems we are stuck in setting up official buildd machines.
Currently this is working by the Debian RISC-V buildd team.
Unfortunately, haven't got the latest news from them for a long time.
But there is no doubt that they are working hard on it.

BR,
Bo

I will ask the RISCV64 Buildd team about current status.
