3022 6003 d 18 h decky /branches/dd/ device drivers branch  
2071 6501 d 8 h jermar /trunk/ (c) versus (C)  
1787 6691 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1124 6800 d 18 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.
 
1053 6808 d 12 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
534 6910 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6910 d 9 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6922 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
435 6939 d 8 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
 
416 6956 d 15 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address.
 
414 6957 d 19 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
 
413 6958 d 5 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.
 
412 6958 d 20 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.
 
322 6997 d 6 h jermar /SPARTAN/trunk/arch/ia64/ Reduce IA-64 context_t according to IA-64 ABI.

Make IA-64 port compile again.
 
100 7101 d 12 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Save/restore the rest of AR registers (i.e. RSE registers) in context_save()/context_restore().
 
94 7108 d 7 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.
 
83 7110 d 13 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Add ar.pfs and ar.unat (caller and callee) application registers to context_t.
Change st8/ld8 instructions on general registers to st8.spill and ld8.fill instructions.
 
82 7111 d 6 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add the rest of branch registers to context_t.
Add predicate registers to context_t.
Modify context_save()/context_restore() to save/restore branch registers and predicate registers.
Change SP_DELTA to 0 since both context_save() and context_restore() are leaf procedures and as such don't use the scratch area.
Change pri_t to be __u64 instead of __u32.
 
60 7117 d 15 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Give up attempts to persuade ld to patch the kernel image with proper hardcoded lenghts and addresses.
Add special sections and calculate the numbers manually.
Fix wrong order of operands in sub instructions in memcpy() implementation.
 
59 7118 d 5 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().
