[Qemu-devel] [Bug 1603779] [NEW] AC97 can allocate ~500MB of host RAM

2016-07-17 Thread Andrew Henderson
Public bug reported: While working with qtest test cases generated via fuzzing with QEMU 2.5.0, I discovered some odd behavior for the AC97 virtual device with qemu-system-i386. If AC97_MIC_ADC_RATE is set to the value of 1, the QEMU process allocates over 500MB of additional host RAM. You probabl
