Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.
Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet. |

Add function to find OFW tree node by handle. |
|

6581 d 0 h |

/trunk/ |
Add node handle to in-memory ofw tree node.
This is essential for interrupt mapping on sparc64
and perhaps on other platforms that have OpenFirmware. |

sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree |
|

/trunk/kernel/ |
Support for FFB (Creator 3D) framebuffer detection on sparc64.
(Not tested as the Ultra 60, which I have for testing, and which
only has this type of framebuffer doesn't boot for some unknown reason.) |
|
1897 |
6587 d 21 h |
jermar |
/trunk/ |
Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation. |
|
1896 |
6588 d 13 h |
jermar |
/trunk/ |
Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.
Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI. |

More ofw_tree work and fixes.
Add ofw_tree_lookup().
Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups. |

Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations
More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree
sparc64 boot:
- pass OFW device tree root node pointer to kernel |

C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64. |
|

sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors. |
|

sparc64 work.
Define the istate structure.
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. |
|

sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled. |
|
1844 |
6632 d 16 h |
jermar |
/trunk/kernel/ |
Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra). |
|

Move code duplicated in i8042.c and z8530.c to key.c. |
|
1842 |
6632 d 21 h |

/trunk/kernel/ |
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. |
|
1841 |
6632 d 22 h |
jermar |
/trunk/kernel/ |
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. |
|

Add scan code map for Sun keyboard. |
|
1837 |
6638 d 2 h |
jermar |
/trunk/ |
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. |
|

Remove OpenFirmware calls from kernel/ entirely.
Switch the sparc64 port to use bootinfo.
Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace. |

Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar(). |

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions. |

sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32. |

Move i8042 driver to genarch as it might be used by more architectures. |
|
867 |
6800 d 20 h |
jermar |
/kernel/trunk/ |
Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory. |
