* Determine how to handle atomic functions on ARM.
|
|
GCC inlines are not supported, since the instructionset is ill-equiped for
|
|
this on older (pre-ARMv7) architectures. We possibly have to do something
|
|
similar to the linux kernel helper functions for this....
|
|
|
|
* Figure out how to get page flags (modified/accessed) and implement it ;)
|
|
use unmapped/read-only mappings to trigger soft faults
|
|
for tracking used/modified flags for ARMv5 and ARMv6
|
|
|
|
* Fix serial port mapping. Currently kernel uses the haiku_loader identity
|
|
mapping for it, but this lives in user virtual address space...
|
|
(Need to not use identity mapping in haiku_loader but just
|
|
map_physical_memory() there too so it can be handed over without issues).
|
|
|
|
* Seperate ARM architecture/System-On-Chip IP code. Needed very early on
|
|
(Interrupt Controller, Timer IP block). Should use FDT for this too.
|
|
|
|
* Use FDT to remove all the seperate board definitions in the build. Use a
|
|
"minimal ARM architecture version" as the compile flag for ARM support.
|
|
This to be able to optimize a kernel build for a specific SoC (or family).
|
|
|
|
* Research stack unwinding to implement backtrace support for KDL & friends.
|
|
|
|
* B_MAX_CPU_COUNT should be fixed to be a more sensible future-proof value then 1
|
|
|
|
* KDL disasm module.
|
|
cf.

|
|
|
|
* Add KDL hangman to the boot floppy image for more enjoyment during porting....
|
|
|
|
* Userland...........
