1908
6536 d 10 h
jermar
/trunk/kernel/genarch/
Add function to find OFW tree node by handle.
1907
6536 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
6540 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
1898
6541 d 0 h
jermar
/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
6543 d 8 h
jermar
/trunk/
Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
1896
6543 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.
1895
6546 d 0 h
jermar
/trunk/
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.
1894
6546 d 22 h
jermar
/trunk/
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
1888
6552 d 4 h
jermar
/trunk/
C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
1875
6559 d 1 h
jermar
/trunk/
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.
1851
6576 d 7 h
jermar
/trunk/kernel/
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.
1849
6580 d 9 h
jermar
/trunk/kernel/
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
6588 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
6588 d 5 h
jermar
/trunk/kernel/genarch/
Move code duplicated in i8042.c and z8530.c to key.c.
1842
6588 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
6588 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.
1838
6593 d 5 h
jermar
/trunk/kernel/
Add scan code map for Sun keyboard.
1837
6593 d 12 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.
1790
6615 d 3 h
jermar
/trunk/
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.
1787
6617 d 2 h
decky
/
move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
