sparc64 work.
Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.
Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer. |

Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.
A lot of formatting and indentation fixes. |

Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.
Little bit of formatting and indentation. |

is still polled. |

Rework the z8530 driver so that it is based on z8530 specification rather
than on accidental and limited "compatibility" with i8042. |

i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace. |

Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.
The repository won't compile now. To be fixed in next commits. |

Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).
At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.
Add note to 8bpp pixel functions pointing out drawbacks of that mode. |

sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.
This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.
Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow. |
