State of KVM bits in linux-headers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm a bit unhappy about the current state of our supposed to be
automatically sync'ed linux-headers directory in qemu. It has been
updated several times against undefined kernel trees, means against
neither a released version nor kvm.git. Now, if I run an update against
kvm.git + some local change, I get a churn of removals. Same will happen
when that local change ever goes upstream before the other stuff got
finally committed.

Alex, it looks to me like this is mostly PPC stuff. Can you comment on
the origin and workflow? E.g. KVM_CAP_SW_TLB: This has been added half a
year ago but is not in any Linux release around. Fishy...

I would like to see us avoiding this in the future. Headers update
patches should mention the source and should not be merged until the ABI
changes actually made it at least into kvm.git. Same applies, of course,
to the functional changes related to that ABI. Otherwise we risk quite
some mess on everyone's side.

Another thing: KVM_CAP_PPC_HIOR has been removed again from the kernel
and also the header. Is there real free space now or will the cap
reappear? If there should better be a placeholder, let's add it (to the
kernel).
