Date: Mon, 16 Sep 2024 18:10:06 +0100 Message-ID: <20240916171017.1841767-2-Jonathan.Cameron@huawei.com> X-Mailer: git-send-email 2.43.0 In-Reply-To: <20240916171017.1841767-1-Jonathan.Cameron@huawei.com> References: <20240916171017.1841767-1-Jonathan.Cameron@huawei.com> Precedence: bulk X-Mailing-List: linux-cxl@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-ClientProxiedBy: lhrpeml100003.china.huawei.com (7.191.160.210) To frapeml500008.china.huawei.com (7.182.85.71) The ordering in ACPI specification [1] has bus number in the lowest byte. As ACPI tables are little endian this is the reverse of the ordering used by PCI_BUILD_BDF(). As a minimal fix split the QEMU BDF up into bus and devfn and write them as single bytes in the correct order.
