253 6883 d 6 h jermar /SPARTAN/trunk/arch/ Implement PPC's get_stack_base().

Comment AMD64's get_stack_base().
 
252 6883 d 8 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 6883 d 14 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 6883 d 21 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
245 6883 d 22 h palkovsky /SPARTAN/trunk/ Use ia32 memmap.h/memmapash.h  
243 6884 d 0 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 6884 d 1 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
241 6884 d 19 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
231 6884 d 23 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better coding style  
230 6884 d 23 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 6884 d 23 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Removed mapping of bottom 2GB to kernel space.  
226 6885 d 0 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
 
224 6885 d 5 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
219 6885 d 14 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.
 
216 6885 d 15 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
211 6885 d 17 h palkovsky /SPARTAN/trunk/arch/amd64/ SVN cleanup  
210 6885 d 17 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6886 d 2 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
206 6886 d 4 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 6886 d 5 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().
 
200 6886 d 17 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
197 6886 d 19 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6886 d 19 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
 
194 6886 d 21 h palkovsky /SPARTAN/trunk/arch/amd64/ Code cleanup.  
192 6886 d 21 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.
 
188 6887 d 0 h palkovsky /SPARTAN/trunk/arch/amd64/ AMD64 now can switch into long mode.
Basic page tables working.
 
178 6888 d 1 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
It now boots into protected mode.
 
177 6888 d 3 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 6891 d 18 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 6893 d 2 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.
 
169 6896 d 17 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
167 6898 d 2 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.
 
165 6899 d 20 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6899 d 20 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
4 7079 d 20 h jermar /SPARTAN/trunk/arch/ Added directories for new architectures.
