[Xen-devel] [PATCH v3 0/9] x86: reduce include dependencies

Posted by Jan Beulich 3 weeks ago
In a number of cases I've noticed the x86 emulator, which is quite
slow to build especially with not very new gcc, to re-build when
having changed headers which I wouldn't have expected to be
included there in the first place. Hence I've gone through the
dependencies of that object file and tried to get rid of at least
some of the very odd dependencies there. (Some are being addressed
also be the separately sent mem-access and vm-event patches with a
similar subject.)

1: HVM: reduce domain.h include dependencies
2: HVM: reduce vcpu.h include dependencies
3: HVM: reduce vpt.h include dependencies
4: HVM: reduce vpic.h include dependencies
5: HVM: reduce vioapic.h include dependencies
6: HVM: reduce vlapic.h include dependencies
7: HVM: reduce io.h include dependencies
8: HVM: reduce hvm.h include dependencies
9: reduce mce.h include dependencies

v3: Address build issues in particular with XSM=y + PV_SHIM=y (patch
    1 only).
v2: Address build issues in particular with XSM=y.

I've tried a variety of configs and everything LGTM now.

Posted by Jan Beulich 3 weeks ago
Drop #include-s not needed by the header itself. Put the ones needed
into whichever other files actually need them.

Just FYI: Because of the fair risk of this patch (or later ones in
the series) going stale in perhaps subtle ways I'm intending to
time out waiting for further acks tomorrow. The changes made, after
all, are largely mechanical.

Posted by Jan Beulich 3 weeks ago
Drop an #include not needed by the header itself. While verifying the
header (now) builds standalone, I noticed an omission in a public header
which gets taken care of here as well.

of the header which isn't needed. Put the one needed into the file
actually requiring it.

ones instead. Put the ones needed into whichever other files actually

one that was missing, and move all inside the inclusion guard.
