1256 6594 d 18 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.		  
1212 6601 d 14 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1074 6637 d 21 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1019 6639 d 16 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
534 6740 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6740 d 13 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6752 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
309 6829 d 23 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
192 6836 d 15 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t.		  
180 6837 d 12 h jermar /SPARTAN/trunk/ Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.

Fix heap initialization to take 'heap_delta' into account.

Implement IA-64 get_stack_base().

Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).

More #include cleanup.		  
125 6882 d 11 h jermar /SPARTAN/trunk/ Huge indentation fix.  
75 6946 d 15 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
58 6950 d 8 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
38 6955 d 14 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
27 6964 d 11 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.		  
24 6969 d 13 h jermar /SPARTAN/trunk/ Small fixes.  
16 6978 d 16 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
11 7022 d 9 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
1 7029 d 15 h jermar /SPARTAN/ Initial import
