Hello!
Ninad wrote an emulator for TPM TIS on I2C bus and I was wondering how one
could implement a test case for it so that we can for example read and write
registers. All existing TPM test cases are using qtest API and we spawn a
thread to emulate a TPM and use the qtest API to read/write the ISA TIS's MMIO
registers. The test cases that I see for i2c are all using the qos type of API.
I have tried to use both in a test case but I am not sure whether they go
together at all (from the errors I have seen they don't go together). So what
options would we have? I thought that one could maybe write an i2c driver to
transfer bytes to the device but the i2c in hw/i2c/aspeed_i2c.c looks complex
to reverse engineer to try to get a byte to a connected device. Do you have any
other suggestions?
Regards,
Stefan
