Subject: [edk2-devel] [PATCH v2] MdeModulePkg/Xhci: Skip size round up for TRB during address translation
Date: Tue, 26 Sep 2023 16:24:49 +0800 [thread overview]
Message-ID: <3f126940d742db17c161127670de2f933ae62789.1695716554.git.gao.cheng@intel.com> (raw)
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4560
TRB Template is 16 bytes. When boundary checking is 64 bytes for xHCI
device/host memory address, it may exceed xHCI host memory pool and
cause unwanted DXE_ASSERT. Introduce a new input parameter to indicate
whether to enforce 64byte size alignment and round up. For TRB case,
should set it to FALSE to skip the size round up.
