X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PULL 05/24] hw/sd/pl181: Reset SD card on controller reset X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RSF_0 Z_629925259 SPT_0 Since pl181 is still using the legacy SD card API, the SD card created by sd_init() is not plugged into any bus. This means that the controller has to reset it manually. Failing to do this mostly didn't affect the guest since the guest typically does a programmed SD card reset as part of its SD controller driver initialization, but meant that migration failed because it's only in sd_reset() that we set up the wpgrps_size field.
