3672 5660 d 11 h jermar /trunk/ Merge sparc branch to trunk.  
3594 5677 d 11 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5682 d 18 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5682 d 20 h svoboda /trunk/ Fix bug #67. It was obviously all my fault - I allocated r3 for pcb_ptr, which was alredy used by uarg.  
3584 5682 d 20 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Bugfix: A ppc32 task would hang if it touched unmapped memory - was calling printf() with address-space mutex held.  
3222 5810 d 15 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3200 5815 d 18 h svoboda /trunk/kernel/arch/ppc32/src/ Remove buggy assembler memsetb function, call generic C _memsetb instead. Fixes kconsole panic when uspace klog is enabled and memsetb() called from klog_update()  
3193 5818 d 10 h jermar /trunk/kernel/ cstyle fixes  
3189 5823 d 9 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.		  
3071 5845 d 16 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2781 5925 d 18 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2725 5963 d 16 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)		  
2723 5964 d 15 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2227 6267 d 1 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6267 d 10 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2218 6268 d 7 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)		  
2170 6275 d 8 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2089 6337 d 17 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6348 d 10 h jermar /trunk/ (c) versus (C)  
1993 6404 d 18 h decky /trunk/ make framebuffer code more generic
