OK, nobody interested in this issue.
I post my own solution. Cause QEMU does not support I2C bus level data transfer, it has delay when transfer multi-touch data from QEMU to guest Linux.
So we create a shared memory on guest Linux kernel driver, and QEMU transfers the data directly through the shared memory, and it has a good speed.
