282 6918 d 23 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.
 
281 6919 d 7 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.

277 6919 d 11 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
273 6919 d 13 h palkovsky /SPARTAN/trunk/ Changes to make ia32 smp code not architecture dependent.
Changes to accomodate new gdtr loading scheme.
 
271 6919 d 14 h decky /SPARTAN/trunk/arch/ia32/src/ yet another GDT/IDT fix/cleanup  
269 6919 d 15 h decky /SPARTAN/trunk/arch/ia32/ make IA-32 SMP work again (finally)  
268 6919 d 15 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
267 6919 d 16 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

264 6919 d 19 h cejka /SPARTAN/trunk/ E option in printf added.  
257 6919 d 22 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 6920 d 14 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 6920 d 15 h decky /SPARTAN/trunk/arch/ia32/src/mm/ make IA-32 UP work again (nasty hack)  
244 6920 d 16 h decky /SPARTAN/trunk/arch/ia32/src/ temporarily fix IA-32 boot bug  
243 6920 d 17 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 6921 d 15 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
233 6921 d 15 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 6921 d 16 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
230 6921 d 16 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 6921 d 22 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
222 6921 d 23 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6922 d 8 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
206 6922 d 21 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 6922 d 22 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 6923 d 10 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
196 6923 d 12 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
195 6923 d 12 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 6923 d 14 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 6923 d 18 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.

184 6923 d 22 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 6923 d 22 h cejka /SPARTAN/trunk/ Test for printf added.  
177 6924 d 20 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 6925 d 11 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6928 d 11 h jermar /SPARTAN/trunk/ Small changes.

Make 'cli' be the first instruction in boot.S again.
 
170 6932 d 9 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 6933 d 10 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.
