3493	5682 d 0 h	rimsky	/branches/sparc/	More changes making the code US-III-conformant (mainly in mm).
3467	5707 d 0 h	rimsky	/branches/sparc/	SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.
3343	5741 d 5 h	decky	/branches/sparc/	add sparc branch
2227	6239 d 15 h	decky	/trunk/kernel/	start shutdown infrastructure
2107	6304 d 0 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	6310 d 4 h	jermar	/trunk/kernel/arch/sparc64/src/	Fix creating the kkbdpoll() kernel thread on sparc64 SMP machines. This fixes Ticket #19.
2071	6321 d 1 h	jermar	/trunk/	(c) versus (C)
2048	6353 d 3 h	jermar	/trunk/	Formatting and indentation changes.
2043	6355 d 4 h	jermar	/trunk/kernel/arch/sparc64/src/	Make the sparc64 kernel compile again.
1982	6381 d 9 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	6416 d 10 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	6417 d 1 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	6433 d 2 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	6434 d 7 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	6434 d 9 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	6440 d 1 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	6440 d 23 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	6448 d 9 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	6451 d 9 h	jermar	/trunk/kernel/arch/sparc64/src/	Revert last change. The register window save area is automatically allocated by the SAVE instruction.
1878	6451 d 11 h	jermar	/trunk/kernel/arch/sparc64/src/	Even the first kernel register window after the switch from userspace stack needs proper register window save area [sparc64].
