3742 5797 d 4 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5820 d 17 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5835 d 18 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3343 5926 d 0 h decky /branches/sparc/ add sparc branch  
2089 6495 d 3 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6505 d 20 h jermar /trunk/ (c) versus (C)  
1921 6600 d 21 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6601 d 5 h jermar /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.		  
1919 6601 d 20 h jermar /trunk/kernel/ 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.		  
1912 6608 d 5 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6608 d 18 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.		  
1909 6612 d 19 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.		  
1896 6622 d 19 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.		  
1849 6659 d 5 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 6666 d 22 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).		  
1842 6667 d 3 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 6667 d 4 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.		  
1790 6693 d 23 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 6695 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6696 d 20 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
