Subject: [PATCH v4 00/27] KVM: s390: Introduce arm64 KVM
Date: Mon, 6 Jul 2026 10:52:00 +0200 [thread overview]
Message-ID: <20260706085229.979525-1-seiden@linux.ibm.com> (raw)
This series is a complete rework of previous versions [1], fundamentally
changing the approach to code and header sharing between s390 and arm64.
For the original, now partially outdated, cover letter, have a look at one of
the previous versions [1].
The new approach does not move arm64 code to a shared location. Instead,
during build time, s390 extracts relevant parts of arm64 definitions and
implementation and uses them locally. This results in minimal changes to
existing arm64 code and headers.
To enable s390 to selectively extract relevant definitions while skipping
architecture-specific code (e.g., arm64 assembly), a shared marker is
introduced. The ARM64_S390_COMMON macro marks regions of arm64 code that
are shared with s390:
in arch/arm64/kvm/<code>.c
<arm64 local code>
#ifdef ARM64_S390_COMMON
<shared code>
#endif /* ARM64_S390_COMMON */
<arm64 local code>
ARM64_S390_COMMON is defined for all arm64 compilation units.
During the s390 build, an allow-list of arm64 headers is extracted into
arch/s390/include/generated/arm64/. If a header contains at least one
shared region, only those regions are copied along with the include guard.
If no shared region is found, s390 uses the full header, which is copied
in its entirety. In such cases, a comment is added at the top of the
header to notify arm64 developers that the file is shared with s390 and
changes may impact s390.
For C files, the process is similar. Selected KVM/arm64 C files are
partially extracted into arch/s390/kvm/arm64/generated/code.inc. The s390
arm64 KVM implementation includes these snippets to reuse arm64 code
without changing linkage.
Userspace tools requiring KVM/arm64 uapi on s390 must use the vendored
KVM API, as s390 will not ship nor install arm64 KVM uapi headers.
This approach reduces the churn, especially for arm64 while keeping the
maintenance burden low.
Series structure
KVM symbol cleanup and refactoring (patches 1-5):
Prepare KVM to support two KVM modules in parallel. Clean up KVM module
symbol exports, making it possible to load two KVM modules side by side.
Make the KVM device name configurable and remove KVM_MMIO as a config
option.
Arm64 header and code sharing preparation (patches 6-9):
Mark shareable parts with ARM64_S390_COMMON. Perform minor refactoring
to ease integration into s390.
Code sharing infrastructure for s390 (patches 10&11):
Add Makefile and scripts to extract and build arm64 headers and code for
use by s390.
KVM/s390 reorganization (patches 12-17):
Prepare s390 for a second KVM module. Move existing s390 KVM code into
dedicated s390 and gmap subdirectories to make room for a second KVM
implementation. Refactor gmap to better integrate with the second KVM
implementation.
KVM on s390 (patches 18-26):
Introduce the SAE (Start Arm Execution) instruction as the s390
mechanism for running arm64 guests. Build up the new kvm-arm64 module
incrementally.
I hope that this new approach suits arm64 better. I definitely think this way
of doing things is more elegant, has less churn, and less work for us all.
Some comments:
I want to create a verification tool for you arm guys that mimics the s390 use
of the arm64 code and headers but compiles/works on arm64 as a quick sanity
check for any arm64 developer. I have some general Ideas (A C file including
all the arm code & headers and see if it compiles) about how to do this but no
concrete ideas yet. Pointers/Ideas are highly appreciated
To further harden the extraction of code/headers one could do the following:
1. Expand all the macros on the header/code
a) with -DARM64_S390_COMMON
b) without -DARM64_S390_COMMON
2. The diff of a & b should be the stuff s390 needs
3. Postprocess it a bit (guards and copyight)
But the AWK approach looked more straight forward and simpler.
There is no way around it - In the future Arm64 maintainers should at least
build s390 before sending merge request.

Changes from v3
- Complete rework of the code sharing approach
- Introduced ARM64_S390_COMMON marker for selective extraction
- Build-time extraction instead of development-time sharing
- Minimal impact on arm64 codebase
- Improved gmap refactoring and integration
