3879 5580 d 20 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3754 5627 d 4 h svoboda /trunk/ Fix mips32eb build a bit.  
3390 5738 d 10 h jermar /trunk/kernel/arch/mips32/ Get rid of mips32 legacy init address and size macros.  
3369 5749 d 23 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
3228 5781 d 12 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
2696 5975 d 7 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2458 6198 d 0 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2454 6198 d 19 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 6312 d 20 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2071 6337 d 20 h jermar /trunk/ (c) versus (C)  
1871 6471 d 7 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1802 6522 d 15 h decky /trunk/ cleanup and unify the build system  
1787 6527 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1746 6550 d 19 h decky /kernel/trunk/ prepare GXEmul kernel to use the boot loader  
1627 6562 d 17 h palkovsky /kernel/trunk/arch/mips32/ Fixed size of mips processes, they are larger now.  
1334 6585 d 8 h jermar /kernel/trunk/ Force mips32 frame buffer access to be always big endian.

Fix vmaxlma.c warning when building ia64.
 
1196 6614 d 3 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1191 6616 d 7 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1106 6638 d 18 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1036 6645 d 5 h decky /kernel/trunk/arch/mips32/ grow init size  
938 6648 d 22 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
924 6649 d 8 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
814 6681 d 4 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
797 6682 d 22 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6682 d 23 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 6698 d 23 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6700 d 18 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6707 d 3 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 6712 d 1 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 6716 d 5 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6738 d 15 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 6739 d 5 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6740 d 1 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
575 6741 d 16 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 6743 d 0 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6744 d 19 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6744 d 22 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6746 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6746 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6758 d 19 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).
