4490 5644 d 14 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4220 5706 d 2 h decky /trunk/kernel/ update for string changes  
4207 5707 d 15 h svoboda /trunk/kernel/ strlen() -> str_size().  
4011 5737 d 13 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3790 5790 d 22 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3672 5824 d 14 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5830 d 13 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.		  
2745 6106 d 22 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2510 6281 d 14 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.		  
2071 6512 d 13 h jermar /trunk/ (c) versus (C)  
1974 6583 d 15 h jermar /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 6585 d 20 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1912 6614 d 22 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6615 d 11 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 6618 d 11 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6619 d 13 h jermar /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.		  
1908 6621 d 23 h jermar /trunk/kernel/genarch/ Add function to find OFW tree node by handle.  
1899 6625 d 21 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 6626 d 13 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 6628 d 21 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
