Jian Jun Chen 74bc2f7cfb hv: asyncio: support data match of the same addr ... Virtio legacy device (ver < 1.0) uses a single PIO for all virtqueues. Notifications from different virtqueues are implemented by writing virtqueue index to the PIO. Writing different values to the same addr needs to be mapped to different eventfds by asyncio. This is called data match feature of asyncio. v3 -> v4: * Update the definition of `struct asyncio_desc` Use `struct acrn_asyncio_info` inside it, instaed of defining the duplicated fileds. * Update `add_asyncio` to use `memcpy_s` rather than assigning all the fields using 5 assignment statements. * Update `asyncio_is_conflict` for coding style 120-character line is sufficient to write all conditions. * Update the checks related to `wildcard` Because we require every conditional clause to have a Boolean type in the coding guideline. v2 -> v3: No change v1 -> v2: No change Tracked-On: #8612 Signed-off-by: Jian Jun Chen <jian.jun.chen@intel.com> Signed-off-by: Shiqing Gao <shiqing.gao@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>		2024-06-05 15:23:33 +08:00
