1746 6718 d 5 h decky /kernel/trunk/ prepare GXEmul kernel to use the boot loader  
1627 6730 d 3 h palkovsky /kernel/trunk/arch/mips32/ Fixed size of mips processes, they are larger now.  
1334 6752 d 19 h jermar /kernel/trunk/ Force mips32 frame buffer access to be always big endian.

Fix vmaxlma.c warning when building ia64.
 
1196 6781 d 13 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1191 6783 d 17 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1106 6806 d 4 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1036 6812 d 15 h decky /kernel/trunk/arch/mips32/ grow init size  
938 6816 d 8 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6816 d 18 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
814 6848 d 14 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
797 6850 d 9 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6850 d 10 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 6866 d 9 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6868 d 4 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6874 d 14 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 6879 d 12 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 6883 d 15 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6906 d 1 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 6906 d 15 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6907 d 11 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
