framebuffer cleanup |

Indentation, formatting and minor changes. |

/trunk/kernel/genarch/src/ofw/ |
Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows. |
|
1972 |

Modify selected function to consume less stack space.
Avoid flushw instruction in the sparc64 loader. |

ia32: adopt new IRQ interface, mouse not tested yet |
|
1944 |
6511 d 3 h |
jermar |
/trunk/kernel/ |
Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64. |

Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code. |
|
1931 |
6513 d 1 h |

Add support for IPC notifications even for polled ns16550 based keyboard. |
|
1925 |
6513 d 23 h |
jermar |
/trunk/kernel/genarch/src/kbd/ |
Support for grabbing and releasing z8530 keyboard for sparc64.
We might later add some locking. |
|
1923 |

Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile. |
|
1921 |
6516 d 1 h |
jermar |
/trunk/kernel/ |
Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t. |
|

6516 d 9 h |

/trunk/kernel/ |
Move the new IRQ redirector to ddi/.
Add function for assigning unique device numbers.
Change sparc64/drivers/kbd.c to assign devno to keyboard. |
|

Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only. |

Separate mapping of EBUS interrupts into two parts: EBUS and PCI. |
|
1911 |
6523 d 22 h |
jermar |
/trunk/kernel/ |
Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers. |
|
1910 |
6526 d 22 h |

Rename INO to INR, for the sake of consistency with manuals. |
|

/trunk/ |
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. |

6530 d 10 h |

Add function to find OFW tree node by handle. |
|
1907 |
6530 d 10 h |
jermar |
/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. |
|
1899 |
6534 d 8 h |
jermar |
/trunk/ |
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 |
|

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 |
6537 d 8 h |
jermar |
/trunk/ |
Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation. |
|
1896 |
6537 d 23 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 |

Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as
sparc64 work:
- start implementing TSB support |

- Experimental support for framebuffers with inverted colors. |

Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness. |

Pass "fb.bpp-align" property to userspace so that our fb task works properly even on
framebuffers used in some Sun hardware. |
|

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. |

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

6582 d 2 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). |
|
1843 |

Move code duplicated in i8042.c and z8530.c to key.c. |
|
1842 |
6582 d 7 h |
jermar |
/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 |
6582 d 8 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. |
