This patch adds the stm32f2xx System Configuration Controller. This is used to configure what memory is mapped at address 0 (although that is not supported) as well as configure how the EXTI interrupts work (also not supported at the moment). This device is not required for basic examples, but more complex systems will require it (as well as the EXTI device) Signed-off-by: NAlistair Francis <alistair@alistair23.me> Reviewed-by: NPeter Crosthwaite <peter.crosthwaite@xilinx.com> Message-id: 5d499d7b60b61d5d6dcb310b2e55411b1f53794e.1424175342.git.alistair@alistair23.me Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

The recently introduced feature that allows 32 bit guests to be executed under KVM on a 64-bit host incorrectly handles the case where more than 1 cpu is specified using '-smp N' For instance, this invocation of qemu qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2 produces the following error qemu-system-aarch64: Expected key=value format, found aarch64 which is caused by the destructive parsing performed by cpu_common_parse_features(), resulting in subsequent attempts to parse the CPU option string (for each additional CPU) to fail. So duplicate the string before parsing it, and free it directly afterwards.

By default, we have ioeventfd enabled, so the IO request processing is in IO thread; in the vcpu thread, guest mode is returned to as quickly as possible, and completion is delivered via irqfd.

When the AHCI HBA device is migrated, all of the information that led to the request being created is stored in the AHCIDevice structures, except for pointers into guest data where return information needs to be stored. The "cur_cmd" field is usually responsible for this. To rebuild the cur_cmd pointer post-migration, we can utilize the busy_slot index to figure out where the command header we are still processing is. This allows a machine in a halted state from rerror=stop or werror=stop to be migrated and resume operations without issue.

This is easy, since start_dma already restarts processing from the beginning of the PRDT. Migration is also easy to cover; the comment about busy_slot is wrong, busy_slot will only be set if there is an error. In this case we have nothing to do really. The core IDE code will restart the operation and command list processing will proceed after the erroring command has been completed.

Amazingly, we weren't doing this before. Make sure we migrate the IDEState structure that belongs to the AHCIDevice.IDEBus structure during migrations. No version numbering changes because AHCI is not officially migratable (and we can all see with good reason why) so we do not impact any official builds by altering the stream and leaving it at version 1. This fixes the rerror=stop/werror=stop test case where we wish to migrate a halted job. Previously, the error code would not migrate, so even if the job completed successfully, AHCI would report an error because it would still have the placeholder error code from initialization time.

This only breaks backwards migration compatibility if the bus is in an error state. It is in principle possible to avoid this by making two subsections (one for version 1, and one for version 2, but with the same name) with different "_needed" callbacks. The v1 callback would return true if error_status != 0 and the bus is PATA; the v2 callback would return true if error_status != 0 and the bus is AHCI. Forward migration keeps working.

geometry: hd_geometry_guess function autodetects the drive geometry. This patch adds a block backend call, that probes the backing device geometry. If the inner driver method is implemented and succeeds (currently only for DASDs), the blkconf_geometry will pass-through the backing device geometry. Otherwise will fallback to old logic. blocksize: This patch initializes blocksize properties to 0. In order to set the property a blkconf_blocksizes was introduced. If user didn't set physical or logical blocksize, it will retrieve its value from a driver (only succeeds for DASD), otherwise it will set default 512 value. The blkconf_blocksizes call was added to all users of BlkConf.

Three kinds of callers: 1. On failure, report the error and abort Passing &error_abort does the job. No functional change. 2. On failure, report the error and exit() This is qdev_prop_set_drive_nofail(). Error reporting moves from qdev_prop_set_drive() to its caller. Because hiding away the error in the monitor right before exit() isn't helpful, replace qerror_report_err() by error_report_err(). Shouldn't make a difference, because qdev_prop_set_drive_nofail() should never be used in QMP context. 3. On failure, report the error and recover This is usb_msd_init() and scsi_bus_legacy_add_drive(). Error reporting and freeing the error object moves from qdev_prop_set_drive() to its callers. Because usb_msd_init() can't run in QMP context, replace qerror_report_err() by error_report_err() there. No functional change. scsi_bus_legacy_add_drive() calling qerror_report_err() is of course inappropriate, but this commit merely makes it more obvious. The next one will clean it up.

Commit a818a4b6 changed scsi_bus_legacy_handle_cmdline() to report errors from scsi_bus_legacy_add_drive() with error_report() in addition to returning them. That's inappropriate. Two kinds of callers: 1. realize methods (devices "esp", "virtio-scsi-device" and "spapr-vscsi") The error object gets passed up the call chain until it gets reported again and freed. Example: $ qemu-system-arm -M virt -S -display none \ > -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \ > -device nec-usb-xhci -device usb-storage,drive=foo \ > -device virtio-scsi-pci qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed qemu-system-arm: -device virtio-scsi-pci: Device initialization failed qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized The second message in this error cascade comes from scsi_bus_legacy_handle_cmdline(). The error object then gets passed up to the qdev_init() called from virtio_scsi_pci_init_pci(), which reports it again. 2. init methods (devices "am53c974", "dc390", "lsi53c895a", "lsi53c810", "megasas", "megasas-gen2") init methods need to report their errors with qerror_report(). These don't. The inappropriate error_report() papers over the bug. error_report() isn't the same as qerror_report() in QMP context, but this can't actually happen: QMP can still only hot-plug, and callers call scsi_bus_legacy_handle_cmdline() only on cold-plug. Except for sysbus_esp_realize(), but that can't be hot-plugged at all, as far as I can tell. Fix the init methods and drop the inappropriate error_report() in scsi_bus_legacy_handle_cmdline().
