1780 6603 d 7 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1769 6606 d 2 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1754 6617 d 13 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1702 6624 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6631 d 16 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1221 6676 d 1 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6682 d 11 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1126 6705 d 12 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1119 6706 d 3 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1100 6709 d 3 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1096 6709 d 10 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
959 6716 d 3 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6716 d 4 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
955 6716 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
852 6739 d 9 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
 
799 6751 d 3 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
794 6751 d 8 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
615 6806 d 13 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6806 d 22 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.
 
610 6807 d 6 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6807 d 7 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
593 6809 d 6 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6809 d 6 h palkovsky /kernel/trunk/ Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned.
 
534 6815 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6815 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6827 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6841 d 12 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
413 6863 d 0 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 6876 d 2 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.
 
389 6876 d 13 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
341 6898 d 10 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
332 6899 d 11 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.
 
330 6900 d 6 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad address loading in simulators.
FPU cooprocessor unusable now checks, if it is FPU that is unusable.
 
327 6900 d 23 h palkovsky /SPARTAN/trunk/ Doc updates, small fixes.  
326 6900 d 23 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
