[Qemu-devel] MemoryRegionOps access sizes

[BALATON Zoltan]

Hello,

Could someone please explain how the MemoryRegionOps 
valid.{min,max}_access_size and unaligned and corresponding impl 
constraints work and where are these implemented? And in particular if 
this would work:

static const MemoryRegionOps ops = {
    .read = readfn,
    .write = writefn,
    .valid.min_access_size = 1,
    .valid.max_access_size = 4,
    .impl.min_access_size = 4,
    .impl.max_access_size = 4,
    .endianness = DEVICE_LITTLE_ENDIAN,
};

This is related to this question:
http://lists.nongnu.org/archive/html/qemu-devel/2019-02/msg03157.html
but that's probably ignored in the middle of a thread so I ask separately.

Thank you,
BALATON Zoltan
