501 6932 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
452 6947 d 11 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
391 6981 d 9 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 7009 d 21 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
141 7056 d 18 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
125 7062 d 9 h jermar /SPARTAN/trunk/ Huge indentation fix.  
94 7118 d 10 h jermar /SPARTAN/trunk/ IA-64 work.
Add application registers ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_t.
Add store/load operations for ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_save()/restore().
Add application registers ar.rcs, ar.bsp and ar.rnat to context_t.
Proper store/load operations for ar.rcs, ar.bsp and ar.rnat is in the works.

FPU cleanup.
Remove call set_TS_flag() from cpu_identify().
Remove unneeded includes from FPU test #1.
 
90 7119 d 11 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.
 
75 7126 d 13 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
58 7130 d 7 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
22 7151 d 13 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
16 7158 d 15 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.
 
15 7159 d 13 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
 
1 7209 d 14 h jermar /SPARTAN/ Initial import
