3857 5616 d 1 h decky /trunk/ very experimental TLB refill for ppc32  
3856 5616 d 3 h decky /trunk/ ppc32: strict coherency, compatible TLB flush  
3844 5617 d 22 h decky /trunk/ silent kernel console output when user space console is active  
3841 5618 d 2 h decky /trunk/kernel/arch/ppc32/src/ it is essential to setup the decrementer before potential rescheduling  
3839 5618 d 5 h decky /trunk/kernel/arch/ppc32/src/mm/ respect stricker lookup algorithm (first look for colliding PTEs, then look for unused PTEs)  
3838 5618 d 6 h decky /trunk/kernel/ make RANDI a generic macro  
3837 5618 d 6 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3836 5618 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 5619 d 2 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5620 d 1 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3829 5620 d 2 h decky /trunk/ use macio optionally  
3827 5620 d 3 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5641 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 5641 d 20 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 5656 d 4 h decky /trunk/kernel/arch/ppc32/src/ redraw kernel cosnole on ppc32  
3672 5674 d 23 h jermar /trunk/ Merge sparc branch to trunk.  
3594 5691 d 23 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5697 d 7 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5697 d 8 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 5697 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 5825 d 3 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3200 5830 d 6 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 5832 d 23 h jermar /trunk/kernel/ cstyle fixes  
3189 5837 d 21 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.
 
3071 5860 d 4 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2781 5940 d 6 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2725 5978 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 5979 d 3 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2227 6281 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6281 d 22 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 6282 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 6289 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 6352 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6362 d 23 h jermar /trunk/ (c) versus (C)  
1993 6419 d 7 h decky /trunk/ make framebuffer code more generic  
1944 6453 d 2 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1934 6454 d 10 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6454 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 6455 d 4 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6455 d 9 h decky /trunk/kernel/ cleanup for new IRQ subsystem
