to add new devices. Abstract the Platform more so that
it is unnecessary to know know platform specifics for
interrupting or translating PCI DMA addresses.
dev/ide_ctrl.cc:
convert to parameter struct for initialization
use the interrupt functions in the PciDev base class
convert from tsunami to using platform
We don't need an interrupt controller here.
dev/ide_ctrl.hh:
don't use Tsunami, use Platform
make the IdeDisk a friend so that it can access my plaform
convert to parameter struct for construction
dev/ide_disk.cc:
don't use tsunami references, but platform references
dev/ns_gige.cc:
Convert to parameter struct for initialzation. Use code in
base class for interrupts so we don't need to know anything
about the platform. Don't need an IntrControl *.
dev/ns_gige.hh:
We don't need a Tsunami * anymore
convert to a parameter struct for construction
dev/pcidev.cc:
deal with new parameter struct
dev/pcidev.hh:
- Move all of the configuration parameters into a param struct
that we can pass into the constructor.
- Add a Platform * for accessing new generic interrupt post/clear
and dma address translation fuctions
- Create functions for posting/clearing interrupts and translating
dma addresses
dev/platform.cc:
have default functions that panic on pci calls
dev/platform.hh:
don't make the pci stuff pure virtual, but rather provide
default implementations that panic. Also, add dma address
translation.
dev/tsunami.cc:
this-> isn't necessary here.
add pci address translation
dev/tsunami.hh:
implement the pciToDma address translation
