867 6683 d 3 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 6684 d 17 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
845 6688 d 6 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context
 
843 6688 d 21 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.
 
833 6692 d 16 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6696 d 18 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
815 6697 d 4 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
765 6702 d 20 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6703 d 2 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
760 6703 d 5 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.
 
756 6704 d 17 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.
 
727 6716 d 19 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6723 d 4 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
674 6732 d 6 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6746 d 23 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6747 d 17 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)
 
625 6752 d 1 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
586 6757 d 1 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
581 6757 d 5 h palkovsky /kernel/trunk/ Small debug changes.  
569 6758 d 19 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
534 6762 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6762 d 22 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6775 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6775 d 19 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
475 6787 d 3 h jermar /SPARTAN/trunk/ Define atomic_t type.  
421 6802 d 17 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 6810 d 8 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.
 
413 6810 d 18 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
391 6823 d 19 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.

Some naming changes in swap functions.
 
332 6847 d 5 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
 
294 6853 d 8 h jermar /SPARTAN/trunk/arch/ Add timeout to kmp() so that we don't deadlock while waiting for AP's to come up.

Improve comment in byteorder.h.
 
292 6853 d 18 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
