[PATCH v16 00/99] arm tcg/kvm refactor and split with kvm only support

Posted by Alex Bennée 5 months, 3 weeks ago
Hi,

I have picked up the baton from Claudio to try and get the ARM
re-factoring across the line. Most of the patches from Claudio remain
unchanged and have just had minor fixups from re-basing against the
moving target. I've done my best to make sure any fixes that have been
made in the meantime weren't lost.

I've included Phillipe's qtest_has_accel v7 patches (I had problems
with v8) to aid in my aarch64 testing. I'm expecting them to be
up-streamed by Phillipe in due course. I've also nabbed one of
Phillipe's Kconfig tweaks to allow for target specific expression of
some config variables.

The main thing that enables the --disable-tcg build is the addition of
--with-devices-FOO configure option which is a mechanism to override
the existing default device configurations. The two that I've been
testing are a 64 bit only build on x86:

  '../../configure' '--without-default-features' \
     '--target-list=arm-softmmu,aarch64-softmmu' \
     '--with-devices-aarch64=../../configs/aarch64-softmmu/64bit-only.mak'

which results in the aarch64-softmmu build only supporting sbsa-ref,
virt and xlnx-versal-virt.

The second is a KVM only cross build:

  '../../configure' '--disable-docs' \
    '--target-list=aarch64-softmmu' \
    '--enable-kvm' '--disable-tcg' \
    '--cross-prefix=aarch64-linux-gnu-' \
    '--with-devices-aarch64=../../configs/aarch64-softmmu/virt-only.mak'

Finally I've made a few minor Kconfig and testing tweaks before adding
some gitlab coverage. As a result I was able to drop the Revert: idau
patch because I can properly build an image without stray devices in
the qtree.

The following need review:

 - gitlab: defend the new stripped down arm64 configs
 - tests/qtest: make xlnx-can-test conditional on being configured
 - tests/qtest: split the cdrom-test into arm/aarch64
 - hw/arm: add dependency on OR_IRQ for XLNX_VERSAL
 - target/arm: move CONFIG_V7M out of default-devices

Re: [PATCH v16 00/99] arm tcg/kvm refactor and split with kvm only support

Posted by Liang Yan 2 months, 1 week ago
Hi Alex,

I am wondering the current status on this patch series.

I have been working on it recently, I am wondering f you have a wip-git-repo,  I can send my patches there if not duplicated,

otherwise I can resend the series here with a  new rebase and some fixes based on the comments.

Let me know what you think, thanks.


Regards,

Liang

Re: [PATCH v16 00/99] arm tcg/kvm refactor and split with kvm only support

The current state of my tree is:

  https://github.com/stsquad/qemu/tree/arm/refactor-tcg-accel-split-v17

I haven't had a chance to look at it in the last few months but some
bits and pieces have been merged including a few Kconfig tweaks and the
--with-default-FOO patches.

Whichever works for you. You can either apply your patches to my WIP
branch and re-base and post the lot or you can apply my last post and
fix up from there. The former may save you some conflict resolutions as
that it more or less what I've been doing.

When you post the series please CC me so I can keep in the loop. A lot
of the earlier patches are already reviewed so hopefully the
non-controversial stuff can get merged into target-arm.next fairly
quickly now we have 6.1 out of the door.

Without using --with-devices-aarch64, I'm getting:

both --enable-xen and --disable-xen.

Is that expected?

IIRC (this was looong ago) before this configuration was not
buildable and Kconfig was erroring with something like:
"dependency not satisfied: ARM_V7M select TCG"
