- makeCoherent should be called after TBX finished processing - this is when tagAddress is updated with taskCount makeCoherent is called from makeNonResident which is invoked just after flush and may happen before TBX server finished processing leading to invalid data to be read back to CPU accessible memory - this fix adds waiting for taskCount to blocking calls for TBX CSR before calling makeNonResident on surfaces to guarantee correct data from TBX server is ready.
