Subject: Test for TPM TIS on I2C bus
Date: Wed, 22 Mar 2023 14:14:10 -0400 [thread overview]
Message-ID: <dd43ec84-51e4-11f7-e067-2fb57a567f09@linux.ibm.com> (raw)
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
