[PATCH for-6.2 0/8] softmmu: Clean up arch_init.c

[Peter Maydell]

This patchset does some cleanups of arch_init.c.  The bit I started
out caring about was getting rid of the TARGET_* ifdef ladder (in
patch 4 we make meson.build define QEMU_ARCH in config-target.h
instead) -- this kind of ifdef ladder is nasty because it's always
another place in the code that needs updating when we add or remove a
target.  I think this was one of the last remaining "every single
arch touches this" ones.  The rest of the patchset is stuff I noticed
when I started looking at what else arch_init.c was doing.

The graphic_width/height/depth target-specific defaults that
arch_init.c does also look like they could use cleanup.  My guess is
that we should instead have a per-machine default graphics
width/height/depth.  But that's a separate thing and more work than I
felt like doing this morning :-)

[PATCH for-6.2 1/8] softmmu: Use accel_find("xen") instead of xen_available()

[Peter Maydell]

The xen_available() function is used only to produce an error
for some Xen-specific command line options in QEMU binaries where
Xen support was not compiled in: it just returns the value of
the CONFIG_XEN define.

Now that accelerators are QOM classes, we can check for
"does this binary have Xen compiled in" with accel_find("xen"),
and drop the xen_available() function.

[PATCH for-6.2 2/8] monitor: Use accel_find("kvm") instead of kvm_available()

[Peter Maydell]

The kvm_available() function reports whether KVM support was
compiled into the QEMU binary; it returns the value of the
CONFIG_KVM define.

The only place in the codebase where we use this function is
in qmp_query_kvm(). Now that accelerators are based on QOM
classes we can instead use accel_find("kvm") and remove the
kvm_available() function.

[PATCH for-6.2 5/8] arch_init.h: Add QEMU_ARCH_HEXAGON

[Peter Maydell]

When Hexagon was added we forgot to add it to the QEMU_ARCH_*
enumeration.  This doesn't cause a visible effect because at the
moment Hexagon is linux-user only and the QEMU_ARCH_* constants are
only used in softmmu, but we might as well add it in, since it's the
only architecture currently missing from the list.

qdev-monitor.c is perhaps less than ideal.  It's better than
arch_init.h, though.

[PATCH for-6.2 7/8] arch_init.h: Don't include arch_init.h unnecessarily

[Peter Maydell]

arch_init.h only defines the QEMU_ARCH_* enumeration and the
arch_type global. Don't include it in files that don't use those.

[PATCH for-6.2 8/8] stubs: Remove unused arch_type.c stub

[Peter Maydell]

We added a stub for the arch_type global in commit 5964ed56d9a1 so
that we could compile blockdev.c into the tools.  However, in commit
9db1d3a2be9bf we removed the only use of arch_type from blockdev.c.
The stub is therefore no longer needed, and we can delete it again,
together with the QEMU_ARCH_NONE value that only the stub was using.
