[PATCH v9 00/10] accel: Allow targets to use Kconfig

[Philippe Mathieu-Daudé]

Missing review:
- 03/10 MAINTAINERS: Cover the HAX accelerator stub
- 04/10 configure: Generate rule to calculate base arch of target

This series include generic patches I took of the KVM/ARM
specific series which will follow.

- Update accelerators in MAINTAINERS
- Add accel/Kconfig
- Allow targets to use their how Kconfig

Since v8:
- Fixed typo in patch 10 (Stefan)

Since v7:
- Generate base-arch() (Alex)
- Do not deprecate HAXM

Since v6:
- Fixed typo 'startwith' -> 'startswith' (armbru)

Since v5:
- Fixed typo in patch #4 subject
- Added David R-b tag
- Stripped --- comments

Since v4:
- Addressed rth review comments in rules.mak

Since v3:
- Fixed base-arch() rule (rth)
- Dropped 'semihosting: Make the feature depend of TCG'

Since v2:
- Addressed Thomas review comments
- Fixed problem when including TARGET instead of BASE_TARGET

Since v1:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg689024.html
- Drop HVF MAINTAINERS patch (merged elsewhere)
- Kconfig-select SEMIHOSTING (bonzini)
- Drop user-mode selection patches
- consider m68k/nios2/xtensa/riscv (pm215)
- reword Kconfig SEMIHOSTING description (pm215)
- reset some of rth R-b tags

[PATCH v9 04/10] configure: Generate rule to calculate the base architecture of a target

[Philippe Mathieu-Daudé]

From: Alex Bennée <alex.bennee@linaro.org>

As we encode the base architecture in configure.sh, we can emit
the base-arch() function into config-host.mak.

I'm not sure it is implicit by the S-o-b tag following, so:

I found this change a bit strange, but maybe I am missing some context.

Would it not be easier to read the information from the
config-target.mak files as it is already emitted there?

Ciao,

Claudio

This is used in patch 9:
"Makefile: Allow target-specific optional Kconfig"
https://www.mail-archive.com/qemu-devel@nongnu.org/msg713823.html

So you are suggesting moving the SUBDIR_DEVICES_MAK creation code
to Makefile.target, before until now it is target-agnostic but we
are making it target-specific. Yes, it could work...

I keep respining this series since the semihosting rework. Frankly
I don't remember why it became so complicated, I need to jump into
the code again.

I guess when Paolo introduced Kconfig, the accelerator configs were
almost static, so SUBDIR_DEVICES_MAK was only dependent of host
config.

The semihosting "device" depends of accelerator and target configs.

Maybe the problem is to see minikconf generating device selectors,
as kconfig is also used for generic features (such accelerator,
not really "device").

This might be solved easily using Meson... Maybe better wait for it?

I think you are right, some of the features are not devices. Maybe another variable could
hold the target-specific features, getting the input from the target makefile? hmm...

Not sure about this one, should be possible to solve with makefiles also,
but I didn't try; I'll try to set things up to get a better understanding.

[PATCH v9 05/10] Makefile: Remove dangerous EOL trailing backslash

[Philippe Mathieu-Daudé]

One might get caught trying to understand unexpected Makefile
behavior. Trailing backslash can help to split very long lines,
but are rather dangerous when nothing follow. Preserve other
developers debugging time by removing this one.

[PATCH v9 08/10] accel/Kconfig: Add the TCG selector

[Philippe Mathieu-Daudé]

Expose the CONFIG_TCG selector to let minikconf.py uses it.

When building with --disable-tcg build, this helps to deselect
devices that are TCG-dependent.

[PATCH v9 10/10] accel/tcg: Add stub for probe_access()

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The TCG helpers were added in b92e5a22ec3 in softmmu_template.h.
probe_write() was added in there in 3b4afc9e75a to be moved out
to accel/tcg/cputlb.c in 3b08f0a9254, and was later refactored
as probe_access() in c25c283df0f.
Since it is a TCG specific helper, add a stub to avoid failures
when building without TCG, such:

  target/arm/helper.o: In function `probe_read':
  include/exec/exec-all.h:362: undefined reference to `probe_access'

Re: [PATCH v9 00/10] accel: Allow targets to use Kconfig

[Philippe Mathieu-Daudé]

Hi Paolo,

Claudio raised an issue with patch #4, so at this point
I have to admit again having the KVM-only build merged
for the next release won't be possible :(

Only patch #9 depends on patch #4. Are you OK to take
the rest of the series, patches 1-3, 5-8, 10 (all but
4 and 9). Patches are fully reviewed. If it is easier
for you I can respin without 4/9.

Thanks,

Phil.

Yes, sounds good.  Patch 4 isn't great and with Meson we can indeed do
better because all config-target.mak files are parsed in a single
non-recursive build.

OK, thanks!
