282 6904 d 10 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.
 
277 6904 d 21 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
275 6904 d 23 h palkovsky /SPARTAN/trunk/arch/ Moved AMD64 kernel above 1MB.

Changes to accomodate new gdtr loading scheme.
 
268 6905 d 2 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.

265 6905 d 5 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).

253 6905 d 10 h jermar /SPARTAN/trunk/arch/ Implement PPC's get_stack_base().

Comment AMD64's get_stack_base().
 
252 6905 d 11 h palkovsky /SPARTAN/trunk/arch/amd64/ Added volatile to inb/outb, so that it does not optimeze
lot of things out anymore.
Working delay loop.
 
251 6905 d 18 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
248 6906 d 0 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
245 6906 d 1 h palkovsky /SPARTAN/trunk/ Use ia32 memmap.h/memmapash.h  
243 6906 d 3 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.
 
242 6906 d 4 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
241 6906 d 23 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
231 6907 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better coding style  
230 6907 d 3 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.
 
229 6907 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Removed mapping of bottom 2GB to kernel space.  
226 6907 d 4 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
 
224 6907 d 9 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
219 6907 d 17 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.
 
216 6907 d 18 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
211 6907 d 20 h palkovsky /SPARTAN/trunk/arch/amd64/ SVN cleanup  
210 6907 d 20 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6908 d 6 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
206 6908 d 7 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 6908 d 8 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().

197 6908 d 22 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6908 d 23 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 6909 d 1 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.

Basic page tables working.
 
178 6910 d 4 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
It now boots into protected mode.
 
177 6910 d 6 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.
 
173 6913 d 21 h jermar /SPARTAN/trunk/ Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.
 
172 6915 d 6 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.
