3880 5744 d 23 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3857 5755 d 1 h decky /trunk/ very experimental TLB refill for ppc32  
3856 5755 d 3 h decky /trunk/ ppc32: strict coherency, compatible TLB flush  
3844 5756 d 22 h decky /trunk/ silent kernel console output when user space console is active  
3841 5757 d 2 h decky /trunk/kernel/arch/ppc32/src/ it is essential to setup the decrementer before potential rescheduling  
3839 5757 d 6 h decky /trunk/kernel/arch/ppc32/src/mm/ respect stricker lookup algorithm (first look for colliding PTEs, then look for unused PTEs)  
3838 5757 d 6 h decky /trunk/kernel/ make RANDI a generic macro  
3837 5757 d 6 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3836 5757 d 7 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5758 d 3 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5759 d 1 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3829 5759 d 2 h decky /trunk/ use macio optionally  
3827 5759 d 3 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5780 d 7 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5780 d 21 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3738 5795 d 5 h decky /trunk/kernel/arch/ppc32/src/ redraw kernel cosnole on ppc32  
3672 5814 d 0 h jermar /trunk/ Merge sparc branch to trunk.  
3594 5831 d 0 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5836 d 7 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5836 d 9 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 5836 d 9 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 5964 d 3 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3200 5969 d 7 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 5971 d 23 h jermar /trunk/kernel/ cstyle fixes  
3189 5976 d 22 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.
 
3071 5999 d 5 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2781 6079 d 7 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2725 6117 d 5 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 6118 d 4 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2227 6420 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6420 d 23 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 6421 d 20 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 6428 d 21 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 6491 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6501 d 23 h jermar /trunk/ (c) versus (C)  
1993 6558 d 7 h decky /trunk/ make framebuffer code more generic  
1944 6592 d 2 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1934 6593 d 11 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6593 d 23 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
 
1928 6594 d 4 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)
