| * | | vdpa: manual forward CVQ buffersEugenio Pérez2022-07-203-1/+63

| * | | vhost: Add svq avail_handler callbackEugenio Pérez2022-07-203-4/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows external handlers to be aware of new buffers that the guest places in the virtqueue. When this callback is defined the ownership of the guest's virtqueue element is transferred to the callback. This means that if the user wants to forward the descriptor it needs to manually inject it. The callback is also free to process the command by itself and use the element with svq_push.

However, in cases where the load raises an exception, we cannot simply execute the store first. This change adds a probe to check that the load will not raise an exception before executing the store. If the load is predicated, this requires special handling. We check the condition before performing the probe. Since, we need the EA to perform the check, we move the GET_EA portion inside CHECK_NOSHUF_PRED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix such errors: 1. We should not use 'unsigned long' type as argument when we use find_first_bit(), and we use ctz64() to replace find_first_bit() to fix this bug. 2. It is not standard to use '1ULL << irq' to generate a irq mask. So, we replace it with 'MAKE_64BIT_MASK(irq, 1)'.
