1008 6636 d 15 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.
 
959 6638 d 7 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6638 d 8 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 6638 d 8 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
825 6670 d 11 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
714 6695 d 10 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)
 
712 6695 d 11 h decky /kernel/trunk/ "Hello world" from user space :)  
703 6697 d 15 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().
 
576 6732 d 3 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
534 6737 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6737 d 8 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6749 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6763 d 16 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
413 6785 d 4 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 6798 d 6 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.
 
309 6826 d 18 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
281 6829 d 4 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
268 6829 d 11 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
224 6831 d 18 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
216 6832 d 4 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
168 6843 d 6 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.
 
136 6874 d 13 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
125 6879 d 6 h jermar /SPARTAN/trunk/ Huge indentation fix.  
117 6910 d 12 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.
 
115 6915 d 4 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.
 
103 6924 d 9 h jermar /SPARTAN/trunk/ Just cleanup.  
92 6935 d 11 h jermar /SPARTAN/trunk/ FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.

Re-enable O3 again.
Revert Makefile.config not to compile in any tests.
 
90 6936 d 7 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.
 
84 6936 d 16 h vana /SPARTAN/trunk/ IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.

Build script for IA-32 changed to build floppy images (image.bin) 1440K long.
 
75 6943 d 10 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6944 d 6 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.
 
68 6944 d 8 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs
 
33 6956 d 3 h jermar /SPARTAN/trunk/ ACPI update (RSDT/XSDT configuration).
Cosmetic changes.
 
31 6959 d 12 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.
 
27 6961 d 6 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.
 
22 6968 d 10 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
7 7021 d 16 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
