3837 5646 d 3 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3836 5646 d 3 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5646 d 23 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5647 d 21 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3829 5647 d 22 h decky /trunk/ use macio optionally  
3827 5647 d 23 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5669 d 4 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 5669 d 17 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 5684 d 1 h decky /trunk/kernel/arch/ppc32/src/ redraw kernel cosnole on ppc32  
3672 5702 d 20 h jermar /trunk/ Merge sparc branch to trunk.  
3594 5719 d 20 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5725 d 3 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3585 5725 d 5 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 5725 d 5 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 5853 d 0 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3200 5858 d 3 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 5860 d 19 h jermar /trunk/kernel/ cstyle fixes  
3189 5865 d 18 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.		  
3071 5888 d 1 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2781 5968 d 3 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2725 6006 d 1 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 6007 d 0 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2227 6309 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6309 d 19 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 6310 d 16 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 6317 d 17 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 6380 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6390 d 19 h jermar /trunk/ (c) versus (C)  
1993 6447 d 3 h decky /trunk/ make framebuffer code more generic  
1944 6480 d 22 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1934 6482 d 7 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6482 d 19 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 6483 d 1 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6483 d 6 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1901 6504 d 1 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.		  
1888 6515 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1837 6557 d 7 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1790 6578 d 22 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1787 6580 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6587 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
