3798 5618 d 5 h rimsky /branches/sparc/kernel/ Implemented preemptible trap handler for sun4v for trapping from kernel (not userspace). Not properly tested/debugged yet. HelenOS now reaches the as_install_arch function (where it, of course, fails).  
3770 5633 d 5 h rimsky /branches/sparc/ Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization).  
3742 5640 d 15 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3607 5675 d 3 h rimsky /branches/sparc/ Cleanup and minor fixes.  
3593 5679 d 4 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3582 5684 d 17 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3467 5735 d 6 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 5763 d 5 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 5769 d 10 h decky /branches/sparc/ add sparc branch  
3193 5819 d 7 h jermar /trunk/kernel/ cstyle fixes  
3175 5830 d 15 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 5845 d 8 h decky /trunk/kernel/ resurrect klog  
3061 5846 d 12 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
2746 5943 d 10 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5943 d 15 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5964 d 13 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 6338 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6339 d 10 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6349 d 6 h jermar /trunk/ (c) versus (C)  
2048 6381 d 8 h jermar /trunk/ Formatting and indentation changes.  
2042 6383 d 10 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6383 d 14 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2015 6388 d 7 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 6399 d 16 h decky /trunk/ start RAM disk support  
1901 6462 d 12 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 6469 d 4 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 6518 d 2 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6518 d 9 h decky /trunk/kernel/generic/src/main/ some debugging output  
1787 6539 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6546 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6560 d 15 h jermar /kernel/trunk/ Cleanup of comments.  
1729 6563 d 3 h decky /kernel/trunk/generic/src/main/ coding style changes  
1702 6567 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6574 d 19 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 6583 d 9 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1389 6590 d 8 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic
 
1315 6598 d 10 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1248 6614 d 10 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6617 d 14 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1224 6618 d 13 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.
