158 6867 d 17 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment  
157 6867 d 17 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
156 6867 d 20 h decky /SPARTAN/trunk/ PPC work in progress  
153 6871 d 8 h jermar /SPARTAN/trunk/ Add memory barriers into spinlock_*().
Implement CS_{ENTER|LEAVE}_BARRIER() for IA-32 (no-op).
Provide incomplete CS_{ENTER|LEAVE}_BARRIER() macros for IA-64 and MIPS as well.

Small changes here and there.
 
149 6883 d 12 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 6888 d 17 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
136 6889 d 17 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
135 6889 d 18 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
125 6894 d 10 h jermar /SPARTAN/trunk/ Huge indentation fix.  
121 6895 d 9 h jermar /SPARTAN/trunk/ Begin MIPS implementation of 4-level page table interface.

Add email address to each item in doc/AUTHORS.

Correct type names in comments in mm/vm.c.
Introduce ptl0 pointer in vm_t.
 
120 6909 d 8 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.
 
119 6910 d 11 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
118 6923 d 13 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 6925 d 15 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 6929 d 15 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 6930 d 8 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 6930 d 18 h jermar /SPARTAN/trunk/src/proc/ Fix wrong locking order in scheduler.  
113 6933 d 7 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 6933 d 11 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 6933 d 11 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.
