* savevm: Remove all the unneeded version_minimum_id_old (arm)Juan Quintela2014-05-131-2/+1
| | | | | | | | | | | | | | | | | | | | | After commit 767adce2d, they are redundant. This way we don't assign them except when needed. Once there, there were lots of cases where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (apart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

* util/fifo8: clear fifo head upon resetBeniamino Galvani2014-02-081-0/+1
| | | | | | | | | | To improve the predictability of fifo8_pop_buf(), the fifo head is set to the start of data buffer upon a reset so that the first call to the function will be able to retrieve all data in the fifo.

* util/fifo8: implement push/pop of multiple bytesBeniamino Galvani2014-02-081-0/+46
| | | | | | | | | | | | | | The patch adds functions fifo8_push_all() and fifo8_pop_buf() which can be used respectively to push the content of a memory buffer to the fifo and to pop multiple bytes obtaining a pointer to the fifo backing buffer. In addition, it implements fifo8_num_free() and fifo8_num_used() which allow to check if a multi-byte operation can be performed.

* hw: move fifo.[ch] to libqemuutilPaolo Bonzini2013-03-011-0/+79
fifo.c is generic code that can be easily unit tested. So it belongs in libqemuutil. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
