Hi, Keir/Jeremy After you picking the two patches into upstream, we found it may break old dom0 when assigned a level-triggered devices to a HVM domain. The casue is that, old dom0 can't provide trigger mode and polarity when they do map_domain_pirq. In attached patches, they introduce a bit to indicate whether old dom0 or not.
xen-introduce-a-bit-to-identify-dom0-type.patch: for hypervisor. 0001-x86-Introduce-a-bit-MAP_COMPAT-mode-for-MAP_PIRQ_TY.patch: for pv ops dom0.
Is there any way for the dom0 kernel to tell whether the hypervisor is implementing the new ABI, so it can choose how to set up interrupts.
MAP_COMPAT_BIT doesn't seem like a very good name, because it implies that setting it reverts to "compatible" behaviour. I assume that leaving it clear enables the historical behaviour and setting it enables the new one (since old kernels won't be setting it).
Maybe better change to MAP_NEW_ABI_BIT ? Since the hypervisor patch didn't
change old code path after introducing this bit, so it is very easy and safe to
backport to xen-3.4-testing tree, and make new dom0 be able to run top of it.
