119 6945 d 2 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
118 6958 d 4 h jermar /SPARTAN/trunk/ Replace confusing comment in scheduler.c.

Add warning/explanatory comment to arch.h saying that CPU, THREAD and TASK macros are preemption-unsafe.		  
117 6960 d 7 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.		  
116 6964 d 7 h jermar /SPARTAN/trunk/ Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries.
Change ACPI map_sdt() to use map_structure().

Small changes in MPS code.
The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space.
Zero TSS descriptor in the newly prepared GDT.		  
115 6964 d 23 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.		  
114 6965 d 9 h jermar /SPARTAN/trunk/src/proc/ Fix wrong locking order in scheduler.  
113 6967 d 22 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.		  
112 6968 d 2 h jermar /SPARTAN/trunk/ Define two placeholder functions for atomic_inc and atomic_dec on IA-64.

Add Ondrej Palkovsky to doc/AUTHORS.

Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken)		  
111 6968 d 3 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.		  
110 6969 d 8 h jermar /SPARTAN/trunk/ SMP recovery patch #1. (SMP still broken)
Move ap_boot() to K_TEXT_START_2 section.
Change ap_boot() to cope with mapping of kernel address space.
Change some addresses in mps.c from kernel to physical.

MIPS.
Move msim dprinter device to 0xB0000000.
This address is from kseg1 (unmapped, uncached) segment.		  
109 6971 d 3 h jermar /SPARTAN/trunk/ Discard 'copy' parameter of map_page_to_frame().
Introduce 'root' parameter of map_page_to_frame().
If 'root' is zero, page directory address is read from CPU.
Otherwise 'root' is used as page directory address.

Add missing word to new doxygen-style comments in scheduler.c.		  
108 6971 d 8 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
107 6971 d 8 h decky /SPARTAN/trunk/src/ doxygen-style comments
cleanups		  
106 6971 d 10 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 6971 d 23 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.		  
104 6974 d 2 h bondari /SPARTAN/trunk/doc/ Add Sergey Bondari to the authors - workstation is ready :)  
103 6974 d 4 h jermar /SPARTAN/trunk/ Just cleanup.  
102 6977 d 3 h jermar /SPARTAN/trunk/ IA-64 work.
Redefine FRAME_SIZE to "(16*1024)" instead of "2*4096". Note that the latter definition was wrong because of the lack of "()".
Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S.
Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init().
In start.S, write r0 to ar.bspstore.

Janitorial fixes.
Add count_t type.
Replace several occurrences of int and __u32 by count_t or size_t.
Shorten several panic strings.		  
101 6978 d 6 h cejka /SPARTAN/trunk/arch/ia32/src/boot/ Small bug in e820 memmap function repaired.  
100 6978 d 6 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Save/restore the rest of AR registers (i.e. RSE registers) in context_save()/context_restore().		  
99 6979 d 14 h jermar /SPARTAN/trunk/ Replace "THREAD->cpu" with "CPU" in scheduler().

Add trailing '\n' to memmap.h
Fix some translations.
Relpace one Czech sentence with its English translation.		  
98 6980 d 7 h cejka /SPARTAN/trunk/arch/ia32/ first version of e820 memmap  
97 6980 d 10 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.		  
96 6981 d 12 h jermar /SPARTAN/trunk/doc/ Add Josef Cejka to doc/AUTHORS.
