174 7011 d 3 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.
 
167 7017 d 11 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 7041 d 4 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 7046 d 10 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
108 7094 d 9 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config
 
106 7094 d 11 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.
 
105 7095 d 0 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.
 
97 7103 d 12 h jermar /SPARTAN/trunk/ Add context_set() macro to support extended behaviour for architectures with more than one stack (e.g. IA-64).
Now there is one generic context_set() defined in include/context.h and one IA-64 specific defined in arch/ia64/include/context.h.
 
81 7111 d 4 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().
 
78 7115 d 3 h jermar /SPARTAN/trunk/ IA-64 cosmetics.
Add ski_init_console() and ski_putchar() to ski.c to perform ski specific tasks.

Change the copyright string in main.c to display both copyrights on a new line.
 
77 7115 d 4 h jermar /SPARTAN/trunk/ Add %P and %p formatters to printf for printing pointers in maximum bit width.
Add %Q and %q formatters to printf for printing 64-bit integers.
 
76 7116 d 4 h jermar /SPARTAN/trunk/ For each architecture, add function/macro FADDR that calculates absolute address of a function referenced by void (* f)(void).
IA-32 and MIPS gcc's use direct addressing (f == FADDR(f)) while IA-64 gcc uses indirect addressing (f != FADDR(f)).

Tweaks in IA-64 Makefile.inc to declare constant gp and main Makefile to consider ASFLAGS when compiling .s targets.
 
71 7117 d 4 h jermar /SPARTAN/trunk/src/main/ Declare 'HelenOS project' as the copyright holder from 2005.  
68 7117 d 5 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs
 
47 7120 d 10 h jermar /SPARTAN/trunk/src/main/ Remove redundant comments.  
46 7120 d 10 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.
 
37 7125 d 13 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.
 
34 7128 d 8 h jermar /SPARTAN/trunk/ More ACPI work.
Initial MADT table parsing.

SMP renaming and reorganization to reflect there are more ways to bring SMP up.
 
32 7131 d 3 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.
 
27 7134 d 2 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.
 
26 7136 d 10 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.
 
23 7139 d 8 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
16 7148 d 8 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.
 
15 7149 d 6 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
 
11 7192 d 1 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.
 
5 7196 d 3 h jermar /SPARTAN/trunk/ TLB shootdown.  
1 7199 d 7 h jermar /SPARTAN/ Initial import
