This routine is called to process capsules.
|
|
|
|
Caution: This function may receive untrusted input.
|
|
|
|
The capsules reported in EFI_HOB_UEFI_CAPSULE are processed.
|
|
If there is no EFI_HOB_UEFI_CAPSULE, this routine does nothing.
|
|
|
|
This routine should be called twice in BDS.
|
|
1) The first call must be before EndOfDxe. The system capsules is processed.
|
|
If device capsule FMP protocols are exposted at this time and device FMP
|
|
capsule has zero EmbeddedDriverCount, the device capsules are processed.
|
|
Each individual capsule result is recorded in capsule record variable.
|
|
System may reset in this function, if reset is required by capsule and
|
|
all capsules are processed.
|
|
If not all capsules are processed, reset will be defered to second call.
|
|
|
|
2) The second call must be after EndOfDxe and after ConnectAll, so that all
|
|
device capsule FMP protocols are exposed.
|
|
The system capsules are skipped. If the device capsules are NOT processed
|
|
in first call, they are processed here.
|
|
Each individual capsule result is recorded in capsule record variable.
|
|
System may reset in this function, if reset is required by capsule
|
|
processed in first call and second call.
|
|
|
|
@retval EFI_SUCCESS There is no error when processing capsules.
|
|
@retval EFI_OUT_OF_RESOURCES No enough resource to process capsules.
