Ticket #93 fix:
Exceptin handling re-written in assembly. |
|

/branches/arm/kernel/arch/arm32/src/ |
Change the exception handling logic:
Exception handler switches from exception mode to kernel mode(supervisor mode) before proceeding to
the exc_dispatch() C function. This assures that exception handling is re-entrant and
kernel would not get confused with different processor modes inside the kernel.
Also fixes a kernel panic during nested interrupts. |

kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone() |

Introduce a more platform-neutral name for programmed I/O.
The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers. |
