Subject: [PATCH v2 08/10] MdeModulePkg NvmExpressDxe: Add NamespaceId validity check in PassThru
Date: Thu, 1 Sep 2016 10:33:05 +0800 [thread overview]
Message-ID: <1472697187-16092-9-git-send-email-hao.a.wu@intel.com> (raw)
In-Reply-To: <1472697187-16092-1-git-send-email-hao.a.wu@intel.com>
According to the UEFI spec, EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL.PassThru()
should return EFI_INVALID_PARAMETER if the input 'NamespaceId' is invalid
for the NVM Express controller. This commit adds check in PassThru() to
follow this rule.
