168 6867 d 0 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 6868 d 9 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.		  
164 6870 d 3 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
160 6875 d 23 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.		  
158 6876 d 7 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment  
157 6876 d 7 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
156 6876 d 10 h decky /SPARTAN/trunk/ PPC work in progress  
153 6879 d 23 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 6892 d 2 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 6897 d 7 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
136 6898 d 7 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.  
135 6898 d 8 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
125 6903 d 0 h jermar /SPARTAN/trunk/ Huge indentation fix.  
121 6904 d 0 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 6917 d 22 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 6919 d 1 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
118 6932 d 3 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 6934 d 6 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 6938 d 6 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 6938 d 22 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.
