2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+0
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+1
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-10-17sd: Avoid access to NULL BlockDriverStateAndreas Färber1-1/+1
Commit 4f8a066b5fc254eeaabbbde56ba4f5b29cc68fdf (blockdev: Remove IF_* check for read-only blockdev_init) added a usage of bdrv_is_read_only() to sd_init(), which is called for versatilepb, versatileab and xilinx-zynq-a9 machines among others with NULL argument by default, causing the new qom-test to fail. Add a check to prevent this. Suggested-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-10-11blockdev: Remove IF_* check for read-only blockdev_initKevin Wolf7-0/+28
IF_NONE allows read-only, which makes forbidding it in this place for other types pretty much pointless. Instead, make sure that all devices for which the check would have errored out check in their init function that they don't get a read-only BlockDriverState. This catches even cases where IF_NONE and -device is used. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

The data_count variable was being reset on every transfer, including DMA transfer resumptions. This is incorrect, it should only be set on a new command. Manifests as a bug when using ADMA and there is a timer delay between ADMA frames where the fifo is left in a non empty state.
