Subject: [edk2-devel] [edk2-platforms][PATCH v2 4/5] JadePkg: Add PlatformBmcReadyLib to support BMC ready check
Date: Wed, 7 Aug 2024 13:47:30 +0700 [thread overview]
Message-ID: <20240807064731.4049764-5-nhi@os.amperecomputing.com> (raw)
In-Reply-To: <20240807064731.4049764-1-nhi@os.amperecomputing.com>
This adds the PlatformBmcReadyLib library instance, which provides a
function to check whether the BMC is ready for transaction or not. The
function checks the GPIO pin specified by the PcdBmcReadyGpio PCD and
returns TRUE if the pin is set to a logic high level, indicating that
the BMC is ready.
