3582 5672 d 22 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3467 5723 d 10 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.  
3365 5751 d 10 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5757 d 15 h decky /branches/sparc/ add sparc branch  
3193 5807 d 11 h jermar /trunk/kernel/ cstyle fixes  
3175 5818 d 19 h jermar /trunk/kernel/generic/src/main/ Don't print anything before the kernel initializes the first THE
structure. This fixes a regression introduced in r3061. If anything
worked from r3061 until now, it was only due to luck. arm32 was not
that lucky when built with gcc 4.3.1.		  
3097 5833 d 12 h decky /trunk/kernel/ resurrect klog  
3061 5834 d 17 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
2746 5931 d 15 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5931 d 20 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5952 d 17 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2089 6326 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2087 6327 d 14 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6337 d 11 h jermar /trunk/ (c) versus (C)  
2048 6369 d 13 h jermar /trunk/ Formatting and indentation changes.  
2042 6371 d 15 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again		  
2039 6371 d 19 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2015 6376 d 11 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.		  
1999 6387 d 21 h decky /trunk/ start RAM disk support  
1901 6450 d 17 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.		  
1894 6457 d 9 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		  
1833 6506 d 7 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6506 d 14 h decky /trunk/kernel/generic/src/main/ some debugging output  
1787 6527 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6534 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6548 d 19 h jermar /kernel/trunk/ Cleanup of comments.  
1729 6551 d 7 h decky /kernel/trunk/generic/src/main/ coding style changes  
1702 6555 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6563 d 0 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1434 6571 d 13 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1389 6578 d 13 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1315 6586 d 14 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1248 6602 d 14 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6605 d 19 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1224 6606 d 17 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1221 6607 d 9 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6613 d 18 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1164 6620 d 15 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1138 6633 d 15 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1109 6638 d 9 h jermar /kernel/trunk/ Basic futex. Prototype implementation.
