HW_DECOMPRESS_CIS

This attribute selects which CIS hardware accelerated decompression should be performed on. The default value of NULL implies that the first CIS encountered by a decompression molecule is targeted for hardware accelerated decompression. Once a CIS has been selected, any other CIS encountered by hardware decompression molecules will be rejected and the decompression will occur through the appropriate XIL software decoder. A value of -1 is a good value to use to disable hardware-based decompression.

Because XIL has no mechanism for informing the decompressor when a CIS is destroyed, this attribute must also be set in order to perform hardware accelerated decompression on a new CIS.
