277 6885 d 6 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!		  
273 6885 d 9 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.		  
271 6885 d 10 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
269 6885 d 10 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6885 d 11 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
267 6885 d 11 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken

257 6885 d 17 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.		  
247 6886 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size.		  
246 6886 d 10 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
244 6886 d 12 h decky /SPARTAN/trunk/arch/ia32/src/ temporarily fix IA-32 boot bug  
243 6886 d 12 h palkovsky /SPARTAN/trunk/ Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode.		  
235 6887 d 11 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
233 6887 d 11 h jermar /SPARTAN/trunk/arch/ia32/src/mm/ Do not use the unmapped addresses of e820 kernel structures.
Use PA2KA() to access the e820 counter and memtable.		  
232 6887 d 11 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
230 6887 d 12 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.		  
224 6887 d 17 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
222 6887 d 18 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6888 d 3 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
206 6888 d 16 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 17 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().		  
198 6889 d 6 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
196 6889 d 7 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
195 6889 d 7 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		  
192 6889 d 10 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.		  
187 6889 d 14 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.		  
185 6889 d 15 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
184 6889 d 17 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

Make IA-32's before_thread_runs() use SP_DELTA macro.		  
182 6889 d 18 h cejka /SPARTAN/trunk/ Test for printf added.  
177 6890 d 15 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
176 6891 d 6 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6894 d 6 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
170 6898 d 5 h jermar /SPARTAN/trunk/ Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.

Remove two unnecessary cpu_priority_high() calls.		  
168 6899 d 5 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.		  
167 6900 d 14 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.		  
149 6924 d 7 h jermar /SPARTAN/trunk/ Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes.
Some cosmetics in memory map detection.
The IA-32 kernel is functional again.		  
146 6929 d 13 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
144 6929 d 13 h vana /SPARTAN/trunk/ Coding style fix
