[RFC v3 0/9] i386 cleanup
Posted by Claudio Fontana 3 years, 5 months ago
Hi all, in this cleanup series we are back at RFC,
and back at providing the whole series together.

The last patch in particular contains a different way to provide
the accelerator-specific i386 CPU functionality,
compared with RFCv1.

In this series I start by moving all i386-specific accelerators
into subdirs of target/i386/ away from the main target directory.

Btw do we have any minimal testing coverage for HAX? Also Xen?

After the code move I go on and strip away all the cpu dump code
out of helper.c into a new file.
There is a large amount of checkpatch warnings
and errors, but this is due to the copy paste of the old code.

After that I take out tcg-specific stuff from cpu.h and from
helper.c and put it in helper-tcg.h and in a new temporary
tcg-cpu module.

After this I considered and implemented a few options.

Like in RFCv1, I introduced a new MODULE_INIT phase,

MODULE_INIT_ACCEL_CPU

that will trigger the registration of the cpu accel-specific
functionality.

Differently than in RFCv1, the class hierarchy of TYPE_X86_CPUs
has been left untouched, and the registration of cpu models
has again been left untouched,

instead describing the specialized functionality in a struct.

The existing "accel" class hierarchy, which is basically used
to contain machine accelerator-specific initializations,
has also been left untouched, as it cannot be used in user mode.

Motivation and higher level steps:

https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg04628.html

Looking forward to your comments on this proposal,

Ciao,

Claudio
