[PATCH 00/10] target: Provide target-specific Kconfig

[PATCH 00/10] target: Provide target-specific Kconfig

[Philippe Mathieu-Daudé]

Hi,

This series add a Kconfig file to each target, allowing
to select target-specific features there, instead of from
the hardware Kconfig.

This simplifies managing multi-arch features such semihosting.

Series organization:

1/ Some targets use the architecture symbol to select boards and
peripherals (SH4 and LM32), we need to clean that first.

2/ Introduce empty target Kconfig, update meson.

3/ Move architectural features out of hardware:
   - x86 SEV
   - ARM v7m
   - generic semihosting

[following only important to patchew, unrelated to this series]
Based-on: <20210131105918.228787-1-f4bug@amsat.org>

[PATCH 05/10] meson: Introduce target-specific Kconfig

[Philippe Mathieu-Daudé]

Add a target-specific Kconfig.

Target foo now has CONFIG_FOO defined.

Two architecture have a particularity, ARM and MIPS:
their 64-bit version include the 32-bit subset.

I suppose X86_64 should also select I386?
No clue about PPC/RISCV.

[PATCH 08/10] default-configs: Remove unnecessary SEMIHOSTING selection

[Philippe Mathieu-Daudé]

Commit 56b5170c87e ("semihosting: Move ARM semihosting code to
shared directories") selected ARM_COMPATIBLE_SEMIHOSTING which
already selects SEMIHOSTING. No need to select it again.

[PATCH 09/10] target: Move ARM_COMPATIBLE_SEMIHOSTING feature to target Kconfig

[Philippe Mathieu-Daudé]

ARM_COMPATIBLE_SEMIHOSTING is an architecture feature, move its
declaration to each target/ARCH/.

Note, we do not modify the linux-user targets, as user-mode builds
don't use Kconfig.

This isn't correct yet, as Kconfig is primarly designed for devices,
and per docs/devel/kconfig.rst:

  "devices are usually ``default y`` if and only if they have at
   least one ``depends on``;"

So having one machine "depends on AARCH64" selects AARCH64 on ARM :/
I'll see if explicit each arch as 'default n' helps...

Taking this comment back, the approach works but is fragile, as
an incorrect dependency can select the wrong arch and it is hard
to detect.

In docs/devel/kconfig.rst we make the distinction between:

  **subsystems**, of which **buses** are a special case
  **devices**
  **device groups**
  **boards**
  **internal elements**

Are we treating architecture features as internal elements or should we
add some additional words to the kconfig document before we starting to
move stuff there. In fact I realise this is better directed at 5/10 so
for this patch:

Repeating myself through the magic of copy and paste:

In docs/devel/kconfig.rst we make the distinction between:

  **subsystems**, of which **buses** are a special case
  **devices**
  **device groups**
  **boards**
  **internal elements**

I think we need to document the target/* Kconfigs in kconfig.rst at the
same time as adding all of these.

Repeating myself through the magic of copy and paste:

In docs/devel/kconfig.rst we make the distinction between:

  **subsystems**, of which **buses** are a special case
  **devices**
  **device groups**
  **boards**
  **internal elements**

I think we need to document the target/* Kconfigs in kconfig.rst at the
same time as adding all of these.

Re: [PATCH 00/10] target: Provide target-specific Kconfig

[Claudio Fontana]

Hi all, where are we with this series?

I am trying to figure out how to apply the whole thing,
in order to build only compatible ARM boards and devices for KVM-only builds.

Ie, I would like to combine this with:

"arm cleanup experiment for kvm-only build"

https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg02790.html

My series there gets us to a buildable and working KVM-only ARM target, with all make check tests passing.

However, in order to be able to remove more code, remove stubs etc,
I found the presence of incompatible ARM boards and devices as blocking additional cleanups.

Therefore, in order to proceed with additional cleanup in arm, and adding the accel-specific extensions to the cpu class,
I see being able to disable incompatible boards for KVM as necessary.

IIUC there are:

* This series "target: Provide target-specific Kconfig"
* Support disabling TCG on ARM ?
* Support disabling TCG on ARM (part 2) ?

What is the current state here?

Thanks,

Claudio
