Subject: Re: [PATCH V3] MdeModulePkg/Xhci: Initial XHCI DCI slot's Context value
Date: Mon, 12 Dec 2022 03:27:19 +0000	[thread overview]
Message-ID: <DM6PR11MB40259DC433410F04CB8E4B8FCAE29@DM6PR11MB4025.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20221210150824.1231-1-abner.chang@amd.com>

For the 3 patches:
[PATCH V2] MdeModulePkg/XhciPei: Unlinked XhciPei memory block
[PATCH V2] MdeModulePkg/Usb: Read a large number of blocks
[PATCH V3] MdeModulePkg/Xhci: Initial XHCI DCI slot's Context value

I found that they will cause CI failures: https://github.com/tianocore/edk2/pull/3749
Could you help to update them and help to ensure they can pass the CI test? Thanks in advance.

Best Regards,
Hao Wu
