The hierarchy is AHCIController, AHCIPortHandler, AHCIPort and
SATADiskDevice. Each AHCIController has at least one AHCIPortHandler.
An AHCIPortHandler is an interrupt handler that takes care of
enumeration of handled AHCI ports when an interrupt occurs. Each
AHCIPort takes care of one SATADiskDevice, and later on we can add
support for Port multiplier.
When we implement support of Message signalled interrupts, we can spawn
many AHCIPortHandlers, and allow each one of them to be responsible for
a set of AHCIPorts.
Leaking macros across headers is a terrible thing, but I can't think of
a better way of achieving this.
- We need some way of modifying debug macros from CMake to implement
ENABLE_ALL_THE_DEBUG_MACROS.
- We need some way of modifying debug macros in specific source files
because otherwise we need to rebuild too many files.
This was done using the following script:
sed -i -E 's/#cmakedefine01 ([A-Z0-9_]+)/#ifndef \1\n\0\n#endif\n/' AK/Debug.h.in
sed -i -E 's/#cmakedefine01 ([A-Z0-9_]+)/#ifndef \1\n\0\n#endif\n/' Kernel/Debug.h.in
