2014-06-05softmmu: introduce cpu_ldst.hPaolo Bonzini1-0/+35
This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch.

2014-06-02usb: add usb_pick_speedGerd Hoffmann1-0/+1
We can pick the usb port speed in generic code, by looking at the port and device speed masks and looking for the fastest match. So add a function to do exactly that, and drop the speed setting code from usb_desc_attach as it isn't needed any more. This way we can set the device speed before calling port->ops->attach, which fixes some xhci hotplug issues. https://bugzilla.redhat.com/show_bug.cgi?id=1046873 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

To get it out of the default GPIO list. This allows child devices to use the un-named GPIO namespace without having to be SSI aware. That is, there is no more need for machines to know about the obscure policy where GPIO 0 is the SSI chip-select and GPIO 1..N are the concrete class GPIOs (defined locally as 0..N-1). This is most notable in stellaris, which uses a device which has both SSI and concrete level GPIOs.

This makes use of op_blocker and blocks all the operations except for commit target, on each BlockDriverState->backing_hd.

2014-05-28block: Replace in_use with operation blockerFam Zheng3-3/+3
This drops BlockDriverState.in_use with op_blockers: - Call bdrv_op_block_all in place of bdrv_set_in_use(bs, 1). - Call bdrv_op_unblock_all in place of bdrv_set_in_use(bs, 0). - Check bdrv_op_is_blocked() in place of bdrv_in_use(bs). The specific types are used, e.g. in place of starting block backup, bdrv_op_is_blocked(bs, BLOCK_OP_TYPE_BACKUP, ...). There is one exception in block_job_create, where bdrv_op_blocker_is_empty() is used, because we don't know the operation type here. This doesn't matter because in a few commits away we will drop the check and move it to callers that _do_ know the type. - Check bdrv_op_blocker_is_empty() in place of assert(!bs->in_use). Note: there is only bdrv_op_block_all and bdrv_op_unblock_all callers at this moment. So although the checks are specific to op types, this changes can still be seen as identical logic with previously with in_use. The difference is error message are improved because of blocker error info.

2014-05-28block: Introduce op_blockers to BlockDriverStateFam Zheng2-0/+12
BlockDriverState.op_blockers is an array of lists with BLOCK_OP_TYPE_MAX elements. Each list is a list of blockers of an operation type (BlockOpType), that marks this BDS as currently blocked for a certain type of operation with reason errors stored in the list. The rule of usage is: * BDS user who wants to take an operation should check if there's any blocker of the type with bdrv_op_is_blocked(). * BDS user who wants to block certain types of operation, should call bdrv_op_block (or bdrv_op_block_all to block all types of operations, which is similar to the existing bdrv_set_in_use()). * A blocker is only referenced by op_blockers, so the lifecycle is managed by caller, and shouldn't be lost until unblock, so typically a caller does these: - Allocate a blocker with error_setg or similar, call bdrv_op_block() to block some operations. - Hold the blocker, do his job. - Unblock operations that it blocked, with the same reason pointer passed to bdrv_op_unblock(). - Release the blocker with error_free().
