867 6679 d 4 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
860 6680 d 19 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6684 d 7 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6684 d 23 h palkovsky /kernel/trunk/ Made powerpc to get on PearPC to the version print when compiled with -O1:
- create proper memory zones
- switch to real mode on boot
TODO
- kernel relocation during boot
- autodetection of framebuffer settings (PCI?) - now includes hardcoded
settings for PearPc.		  
836 6687 d 20 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6693 d 6 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
793 6695 d 4 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
756 6700 d 19 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
684 6724 d 4 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
674 6728 d 7 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
659 6741 d 8 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
586 6753 d 3 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
577 6753 d 18 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
534 6758 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6758 d 23 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6759 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
503 6771 d 3 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).		  
501 6771 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6771 d 21 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
426 6794 d 5 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.		  
421 6798 d 19 h jermar /SPARTAN/trunk/ Create genarch directory.
Move ppc32 ofw.[ch] to genarch.
Fix prototype for ofw_call() to return __address instead of int (please review).
Fix copyright notice in sparc64/boot/boot.S.		  
414 6806 d 10 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
368 6833 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
343 6842 d 5 h jermar /SPARTAN/trunk/ Finish renaming of mips and ppc ports.  
342 6842 d 5 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
309 6848 d 9 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
266 6851 d 5 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
254 6851 d 10 h decky /SPARTAN/trunk/arch/ppc/ fix stupid assembler bugs in cpu_priority_* (PPC)  
250 6852 d 0 h jermar /SPARTAN/trunk/arch/ppc/src/ Add missing semicolon.  
230 6853 d 4 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
218 6853 d 18 h decky /SPARTAN/trunk/arch/ppc/ update PPC for new hardcoded_* method  
210 6853 d 21 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
207 6854 d 7 h decky /SPARTAN/trunk/ separated stack mapping  
205 6854 d 9 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
201 6854 d 21 h decky /SPARTAN/trunk/arch/ppc/ header fixes  
199 6854 d 21 h decky /SPARTAN/trunk/arch/ppc/ PPC context save/restore  
191 6855 d 1 h decky /SPARTAN/trunk/arch/ppc/ PPC memory size detection  
190 6855 d 2 h decky /SPARTAN/trunk/arch/ppc/src/debug/ PPC panic()  
186 6855 d 7 h decky /SPARTAN/trunk/arch/ppc/ add missing OpenFirmware related files
