Component/Vci Multi Ahci
v21 v22 106 106 Bit-vector, one bit per command in the Command List. These bits are handled as 32 set/reset flip-flops: set by software when a command ha been posted in Command List / reset by hardware when the command is completed. A write command on this register makes a OR between the VCI WDATA field and the current value of the register. 107 107 108 For extensibility issues, the software drivers must access this component using the mnemonics defined [source:trunk/soclib/soclib/module/connectivity_component/vci_multi_ahci/include/soclib/multi_ahci.h here].108 For extensibility issues, the software drivers must use the mnemonics defined [source:trunk/soclib/soclib/module/connectivity_component/vci_multi_ahci/include/soclib/multi_ahci.h here] to access this component . 109 109 110 110 Even if there is only six registers per channel, each channel sub-segment occupies 4K bytes, and the HBA segment must be aligned on a 32 Kbytes boundary.
