228 6886 d 21 h cejka /SPARTAN/trunk/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
227 6886 d 22 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
226 6886 d 22 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
225 6887 d 1 h jermar /SPARTAN/trunk/test/synch/rwlock4/ Revert the change in rwlock #4 test that added cpu_priority_high() and cpu_priority_restore() to random().
It is no longer necessary because spinlock disables preemption at least.		  
224 6887 d 3 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
223 6887 d 3 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
222 6887 d 3 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
221 6887 d 4 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.		  
220 6887 d 4 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6887 d 11 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
218 6887 d 11 h decky /SPARTAN/trunk/arch/ppc/ update PPC for new hardcoded_* method  
217 6887 d 12 h palkovsky /SPARTAN/trunk/arch/ia32/ Bugfix.  
216 6887 d 13 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
215 6887 d 14 h jermar /SPARTAN/trunk/contrib/ Add two more emulator config files.  
214 6887 d 14 h vana /SPARTAN/trunk/src/  
213 6887 d 14 h jermar /SPARTAN/trunk/ Add some comments.  
212 6887 d 15 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
211 6887 d 15 h palkovsky /SPARTAN/trunk/arch/amd64/ SVN cleanup  
210 6887 d 15 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
209 6887 d 15 h decky /SPARTAN/trunk/contrib/ MSIM configuration file  
208 6888 d 0 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6888 d 1 h decky /SPARTAN/trunk/ separated stack mapping  
206 6888 d 2 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.
Build script cleanup amd64.
New code / not working yet / in amd64.		  
205 6888 d 2 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
204 6888 d 3 h decky /SPARTAN/trunk/arch/ppc/include/ PPC interrupt high/low/restore  
203 6888 d 3 h decky /SPARTAN/trunk/contrib/ cross-compiler toolchain build script for IA-32  
202 6888 d 14 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
201 6888 d 14 h decky /SPARTAN/trunk/arch/ppc/ header fixes  
200 6888 d 14 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
199 6888 d 15 h decky /SPARTAN/trunk/arch/ppc/ PPC context save/restore  
198 6888 d 15 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6888 d 16 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
196 6888 d 16 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
195 6888 d 17 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option

Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t.
