Hi Hao:
  I think blocking UpdateCapsule interface is enough for Capsule in RAM.  QueryCapsuleCapabilities can still be used to test capsules before delivering by different sources.

Hello Chao,

I am okay with the usage update for the function.

But I think we need to update the comments for the QueryCapsuleCapabilities()
function within this driver and the 'EFI_QUERY_CAPSULE_CAPABILITIES' service for
EFI_RUNTIME_SERVICES to reflect the fact that even QueryCapsuleCapabilities()
returns without error, the capsule may still be unsupported by UpdateCapsule():

/**
  Returns if the capsule can be supported via UpdateCapsule().

  ...

**/

Hi Hao:
   OK that is a good point. We will follow up to clean this. Tks


Hello Chao,

I am not sure if the update still applies to the UEFI spec with regard to
the description for the QueryCapsuleCapabilities service of EFI_RUNTIME_SERVICES.

  IMO, I think it is fine, but it would be better to double confirm.

Best Regards,
Hao Wu

Hi Hao:
  I think blocking UpdateCapsule interface is enough for Capsule in RAM.  QueryCapsuleCapabilities can still be used to test capsules before delivering by different sources.

Hello Chao,

I am okay with the usage update for the function.

But I think we need to update the comments for the QueryCapsuleCapabilities()
function within this driver and the 'EFI_QUERY_CAPSULE_CAPABILITIES' service for
EFI_RUNTIME_SERVICES to reflect the fact that even QueryCapsuleCapabilities()
returns without error, the capsule may still be unsupported by UpdateCapsule():

/**
  Returns if the capsule can be supported via UpdateCapsule().

  ...

**/

Best Regards,
Hao Wu

For this patch, it only affects UpdateCapsule(). Do we need to update the
behavior for QueryCapsuleCapabilities() as well?

Hao Wu
