Currently all config space fields are of the type __uXX. This confuses people and some drivers (notably vdpa) access them using CPU endian-ness - which only works well for legacy or LE platforms. Update virtio_cread/virtio_cwrite macros to allow __virtioXX and __leXX field types. Follow-up patches will convert config space to use these types. Signed-off-by: Michael S. Tsirkin <mst at

Config space endian-ness is currently a mess: fields are not tagged with the correct endian-ness so it's easy to make mistakes like instanciating config space in native endian-ness. The following patches adding sparse tagging are currently in my tree. Lightly tested. As a follow-up, I plan to add new APIs that handle modern config space in a more efficient way (bypassing the version check).

Dear list, I was trying to create a VarClass for nlme to work with Fay-Herriot (FH) models. The idea was to create a modification of VarComb that instead of multiplying the variance functions made their sum (I called it varSum). After some fails etc... I found that the I was not getting the expected results because I needed to make sigma fixed. Trying to find how to make sigma fixed I run into

virtio 1.0 makes all memory structures LE, so we need APIs to conditionally do a byteswap on BE architectures. To make it easier to check code statically, add virtio specific types for multi-byte integers in memory. Add low level wrappers that do a byteswap conditionally, these will be useful e.g. for vhost. Add high level wrappers that will (in the future) query device endian-ness and act
