2696 6004 d 13 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2458 6227 d 6 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.		  
2454 6228 d 2 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.		  
2125 6342 d 3 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2071 6367 d 2 h jermar /trunk/ (c) versus (C)  
1871 6500 d 14 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1802 6551 d 22 h decky /trunk/ cleanup and unify the build system  
1787 6557 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1746 6580 d 1 h decky /kernel/trunk/ prepare GXEmul kernel to use the boot loader  
1627 6592 d 0 h palkovsky /kernel/trunk/arch/mips32/ Fixed size of mips processes, they are larger now.  
1334 6614 d 15 h jermar /kernel/trunk/ Force mips32 frame buffer access to be always big endian.

Fix vmaxlma.c warning when building ia64.		  
1196 6643 d 10 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6645 d 14 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1106 6668 d 1 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1036 6674 d 12 h decky /kernel/trunk/arch/mips32/ grow init size  
938 6678 d 5 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6678 d 14 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
814 6710 d 10 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
797 6712 d 5 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6712 d 6 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 6728 d 5 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6730 d 1 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6736 d 10 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 6741 d 8 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 6745 d 11 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6767 d 21 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 6768 d 12 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6769 d 8 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.		  
575 6770 d 23 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 6772 d 7 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6774 d 2 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6774 d 4 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6776 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6776 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6788 d 2 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6788 d 4 h decky /kernel/trunk/ preparation for init task loading  
501 6788 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6796 d 1 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6796 d 3 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 6802 d 11 h decky /SPARTAN/trunk/ make configuration variables usage consistent
