Yet another update of the id register series, less changes this time
around.
Changed from v2:
- changed generation of the various register defines via the "DEF"
magic suggested by Richard
- some kvm-only code moved to kvm.c; some code potentially useful to
non-kvm code stayed out of there (the cpu model code will make use
of it, and that one should be extendable outside of kvm -- a
revised version of those patches is still in the works, but I'll be
off for a few days and rather wanted to get this one out first)
Also available at
https://gitlab.com/cohuck/qemu/-/commits/arm-rework-idreg-storage-v3
<v2 cover letter>
Changed from v1:
- Noticed that we missed the hvf code. Converted, compiled, but not tested
as I'm lacking an environment for testing.
- Hopefully incorporated most of the suggested changes -- if I missed
something, it was unintentional unless mentioned below.
- fixed repeated inclusion of definitions
- hopefully made macros more robust
- removed distinction between reading 32/64 values, which was mostly
adding churn for little value
- postponed generating property definitions to the cpu model patches,
where they are actually used
- juggled hunks and moved them to the right patches
- fixed some typos
- rebased to a more recent code base
NOT changed from v1:
- definitions are still generated from the Linux sysregs file
- I still think updating the generated files on demand (so that we can
double check the result) is the right thing to do
- I'm open to changing the source of the definitions from the sysregs
file to the JSON definitions published by Arm; however, I first wanted
to get the code using it right -- we can switch out the code generating
the file to use a different source easily later on, and I'd also like
to steal parts of the script from Linux once integrated (which I think
hasn't happened yet?)
<v1 cover letter>
[Note: I've kept the cc list from the last round of cpu model patches;
so if you're confused as to why you're cc:ed here, take it as a
heads-up that a new cpu model series will come along soon]
This patch series contains patches extracted from the larger cpu model
series (RFC v2 last posted at
https://lore.kernel.org/qemu-devel/20241206112213.88394-1-cohuck@redhat.com/)
and aims at providing a base upon which we can continue with building
support for cpu models, but which is hopefully already an improvement
on its own.
Main changes from the patches in that series include:
- post-pone the changes to handle KVM writable ID registers for cpu models
(I have a series including that on top of this one)
- change how we store the list of ID registers, and access them
basically, use an enum for indexing, and an enum doing encodings in a
pattern similar to cpregs
- move some hunks to different patches
- update the scripts to generate the register descriptions, and run
them against a recent Linux sysregs file
What I've kept:
- generating the register descriptions from the Linux sysregs file
I think that file is still our best bet to generate the descriptions
easily, and updating the definitions is a manual step that can be checked
for unintended changes
- most of the hard work that Eric had been doing; all new bugs in there
are my own :)
</v1 cover letter>

From: Eric Auger <eric.auger@redhat.com>
This new header contains macros that define aarch64 registers.
In a subsequent patch, this will be replaced by a more exhaustive
version that will be generated from linux arch/arm64/tools/sysreg
file. Those macros are sufficient to migrate the storage of those
ID regs from named fields in isar struct to an array cell.
[CH: reworked to use different structures]
[CH: moved accessors from the patches first using them to here,
dropped interaction with writable registers, which will happen
later]
[CH: use DEF magic suggested by rth]

From: Eric Auger <eric.auger@redhat.com>
Introduce scripts that automate the generation of system register
definitions from a given linux source tree arch/arm64/tools/sysreg.
Invocation of
./update-aarch64-sysreg-code.sh $PATH_TO_LINUX_SOURCE_TREE
in scripts directory generates target/arm/cpu-sysregs.h.inc
containing defines for all system registers.
[CH: update to handle current kernel sysregs structure, and to emit
the re-worked register structures; cpu properties will be added
later]

I don't think there is a real appetite to have that script merged in
the kernel. My current plan is to maintain it separately.
But by any mean, take it and do whatever you want with it.
Thanks,

This doesn't seem to be used. I guess this is in preparation for later
usage, when this can do more than just the plain register definition?

This won't work for regs that don't fit this naming scheme. Up to this
point in the series that's only CTR_EL0, later with the auto generation it
will be more. But I guess this can be extended when/if there's an actual
need..

All ID_XXX registers fit the "has an _EL1 suffix" scheme, though, and
these are what we use the _IDREG() accessors for (we use FIELD_DP64 for
CTR_EL0 fields.) (At least, that matches what I see called "ID
registers" in the Arm Arm.)
The sysregs we get via
KVM_ARM_GET_REG_WRITABLE_MASKS/KVM_ARM_FEATURE_ID_RANGE
contain ID_XXX registers, and some more writable registers in the
feature id range which are not really id registers (but which we want to
handle via the command line as well). I think all the non _EL1 registers
we want to handle fall into the latter category (i.e. we're not going to
use the _IDREG() accessors for them?)

In fact, I might have got muddled a bit in my scripts, let me check. (I
think we should simply skip out-of-range regs.)
