4296 5677 d 21 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4295)  
4156 5705 d 23 h trochtova /branches/dd/ changes in trunk (rev 4155) merged into dd branch  
4055 5717 d 1 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6000 d 3 h decky /branches/dd/ device drivers branch  
2227 6416 d 8 h decky /trunk/kernel/ start shutdown infrastructure  
2107 6480 d 17 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2091 6486 d 21 h jermar /trunk/kernel/arch/sparc64/src/ Fix creating the kkbdpoll() kernel thread on sparc64 SMP machines.
This fixes Ticket #19.		  
2071 6497 d 17 h jermar /trunk/ (c) versus (C)  
2048 6529 d 19 h jermar /trunk/ Formatting and indentation changes.  
2043 6531 d 20 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
1982 6558 d 1 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.		  
1920 6593 d 2 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 6593 d 17 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.		  
1903 6609 d 18 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.		  
1901 6610 d 23 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.		  
1899 6611 d 1 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		  
1895 6616 d 18 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 6617 d 15 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		  
1881 6625 d 1 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.		  
1879 6628 d 1 h jermar /trunk/kernel/arch/sparc64/src/ Revert last change.
The register window save area is automatically allocated by the SAVE instruction.
