2015-03-10scsi: Clean up duplicated error in legacy if=scsi codeMarkus Armbruster
Commit a818a4b 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().

2015-01-14hw/scsi/lsi53c895a: add support for additional diag / debug registersPeter Lieven

2014-12-15scsi: Use g_new() & friends where that makes obvious senseMarkus Armbruster
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2014-08-26scsi-bus: Convert DeviceClass init to realizeFam Zheng
Replace "init/destroy" with "realize/unrealize" in SCSIDeviceClass, which has errp as a parameter. So all the implementations now use error_setg instead of error_report for reporting error. Also in scsi_bus_legacy_handle_cmdline, report the error when initializing the if=scsi devices, before returning it, because in the callee, error_report is changed to error_setg. And the callers don't have the right locations (e.g. "-drive if=scsi").

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2013-09-16lsi: add 53C810 variantHervé Poussineau
Currently, treat it exactly as a 53C895A. 53C895A is a 53C810 with more capabilities, so this should work. However, this lets us test different code paths on Linux, which don't use lastest features if it detect a 810, or on some OSes which only support 810 and not 895A (like very old Windows NT versions).

2013-09-16lsi: ignore write accesses to CTEST0 registersHervé Poussineau
53C895A datasheet says that this register is read/write, and that the value returned on read access is dependant of DMA FIFO state. However, nothing is said for written value. 53C810A datasheet gives more insight about this register: "This was a general purpose read/write register in previous SYM53C8XX family chips. Although it is still a read/write register, Symbios reserves the right to use these bits for future 53C8XX family enhancements." This prevents going to the default case, which prints an error message. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
