233 6903 d 1 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 6903 d 2 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
230 6903 d 2 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 6903 d 8 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.  
222 6903 d 9 h decky /SPARTAN/trunk/arch/ia32/ IA-32 GRUB support (alpha)  
216 6903 d 18 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
206 6904 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 6904 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().		  
198 6904 d 20 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
196 6904 d 22 h vana /SPARTAN/trunk/arch/ia32/src/ ASM version of memcopy repaired on ia32  
195 6904 d 22 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 6905 d 0 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 6905 d 5 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.		  
185 6905 d 6 h decky /SPARTAN/trunk/arch/ OpenFirmware support  
184 6905 d 8 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 6905 d 9 h cejka /SPARTAN/trunk/ Test for printf added.  
177 6906 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.		  
176 6906 d 21 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6909 d 21 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
170 6913 d 19 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 6914 d 20 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 6916 d 5 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 6939 d 22 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.

144 6945 d 4 h vana /SPARTAN/trunk/ Coding style fix  
143 6945 d 4 h vana /SPARTAN/trunk/ Disable alignment check  
142 6945 d 5 h vana /SPARTAN/trunk/arch/ia32/src/ Typing error fixed  
141 6945 d 5 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
139 6946 d 1 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
137 6946 d 3 h vana /SPARTAN/trunk/arch/ia32/src/ Comments  
136 6946 d 3 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
132 6946 d 6 h vana /SPARTAN/trunk/arch/ia32/ Added support for error-word generating exceptions in return routine.  
131 6946 d 6 h jermar /SPARTAN/trunk/arch/ia32/src/ Initialize kmp_completion_wq during configuration via ACPI MADT.
Move some generic SMP configuration code from mps.c to smp.c.		  
129 6947 d 3 h jermar /SPARTAN/trunk/arch/ia32/ Implement ACPI MADT operations for interface used by kmp.  
128 6948 d 5 h jermar /SPARTAN/trunk/arch/ia32/ Create IA-32 interface for bringing SMP up.
This interface hides differences between ACPI MADT and MPS configuration tables.
Provide MPS implementation thereof.		  
127 6948 d 6 h jermar /SPARTAN/trunk/arch/ Copyright owner of arch/mips/src/mm/asid.c is Martin Decky.

ACPI code now understands L_APIC and IO_APIC entries in MADT.

120 6965 d 18 h jermar /SPARTAN/trunk/ Generic 4-level page tables interface & implementation (review & test).
Implement more architecture dependant macros on IA-32.
Provide fake implementation on IA-64 and MIPS.
Convert map_page_to_frame() to use the new interface.
Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.		  
117 6982 d 2 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.
