Changes v6 to v7:
Stefano Stabellini
Use QEMU_BUILD_BUG_ON, please do not define your own.
Switched to QEMU_BUILD_BUG_ON.
Dropped Reviewed-by: Paul Durrant (moved below ---)
Changes v5 to v6:
Paul Durrant
Do we need a forward declaration?
Nope. Drooped.
Added Reviewed-by.
Changes v4 to v5:
Paul Durrant
vmware_ioreq_t struct is not really a request any more. Maybe
vmware_regs_t?
Renamed various parts from vmware_ioreq to vmware_regs. Also
HVM_PARAM_VMPORT_IOREQ_PFN to HVM_PARAM_VMPORT_REGS_PFN.
cpu_by_ioreq_id name implies the array is indexed by an id
carries in the ioreq.
Renamed cpu_by_ioreq_id to cpu_by_vcpu_id.
Is cpu_get_vmport_ioreq_from_shared_memory worth its own
function?
Moved in-line.
I don't think you need the barrier anyway.
Dropped the barrier.
Oh, I now realize you mean the same theoretical rather than
actual limit, in which case this can be a build time check
anyway.
Switch to build time check, move to a better place.
You could avoid passing state to both of them by setting
current_cpu here couldn't you?
Yes, moved state usage to handle_vmport_ioreq().
Stefano Stabellini
Error out if it fails with error != -ENOSYS.
Done.
Changes RFC-v2x to v4:
Stefano Stabellini
Please try to get rid of the #ifdefs.
Moved 2 #ifdefs into hw/xen/xen_common.h
Changes v2 to RFC-v2x:
Paul Durrant
Use a 2nd shared page.
Added HVM_PARAM_VMPORT_IOREQ_PFN usage.
Changes v1 to v2:
More info in commit message.
Stefano Stabellini
the registers being passes explicitely by Xen rather than
"hiding" them into other ioreq fields.
Added vmware_ioreq_t
Paolo Bonzini & Alexander Graf
Fixup env access
Added cpu_by_ioreq_id.
Set current_cpu in regs_to_cpu(), clear in regs_from_cpu().
Drop all changes to vmport.c
Note: to use this with Xen either a version of:
[Qemu-devel] [PATCH] -machine vmport=off: Allow disabling of VMWare ioport
emulation
or
