Registers

Register access is controlled by gRegisters and is of type class Registers. It is created automatically by the framework and is guaranteed to exist before any test assumes control. It is also a singleton; meaning only 1 object of its kind will ever exist for each running instance of tnvme. The main job of the gRegisters is to control the reading and writing to any register of a DUT. This includes both the PCI address space and the controller's address space which is pointed to by BAR0/BAR1.

For good examples on how to use this singleton to access the PCI address space please reference file tnvme/GrpPciRegisters/allPciRegs_r10b.cpp in function RunCoreTest(). For good examples on how to use this for controller space register access referencing file tnvme/GrpCtrlRegisters/allCtrlRegs_r10b.cpp.
