1191 6780 d 9 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1106 6802 d 20 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1036 6809 d 7 h decky /kernel/trunk/arch/mips32/ grow init size  
938 6813 d 0 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6813 d 9 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
814 6845 d 6 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
797 6847 d 0 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6847 d 1 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.
 
730 6863 d 0 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6864 d 20 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6871 d 5 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().
 
684 6876 d 3 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 6880 d 6 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6902 d 16 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.
 
604 6903 d 7 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6904 d 3 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
575 6905 d 18 h palkovsky /kernel/trunk/ Added generic exc_register/exc_dispatch functions,
copied from ia32 architecture. Currently only mips32 uses them.

The chardev_t can now be both input & output device (was
needed for serial driver).

Broken other architectures - ia64, sparc, powerpc will not compile.

Mips32 supports input on all msim, gxemul, indy(tested emulation
in gxemul, loses characters), simics. Simics serial line
is done using polling, I was unable to make it produce
an interrupt when the key was pressed.
 
568 6907 d 2 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6908 d 21 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6908 d 23 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6910 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6910 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6922 d 21 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6922 d 23 h decky /kernel/trunk/ preparation for init task loading  
501 6923 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6930 d 20 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6930 d 22 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
458 6937 d 6 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6937 d 6 h decky /SPARTAN/trunk/ new build system almost finished  
455 6937 d 18 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
431 6942 d 6 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
430 6943 d 20 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
429 6944 d 1 h jermar /SPARTAN/trunk/arch/mips32/ For now, compile with -mhard-float.
Libraries required by -msoft-float are not part of gcc.
Moreover, ld doesn't warn about undefined symbols.
 
391 6971 d 20 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.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
376 6981 d 1 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
364 6986 d 8 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.
 
342 6994 d 4 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
341 6994 d 4 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
339 6995 d 2 h palkovsky /SPARTAN/trunk/arch/mips/ Make the objcopy files compatibile with gnu-sgi-irix linker.  
332 6995 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.
