174 6874 d 4 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.
 
173 6874 d 4 h jermar /SPARTAN/trunk/ Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.
 
172 6875 d 12 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.
 
170 6878 d 2 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.
 
169 6879 d 3 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
168 6879 d 3 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 6880 d 12 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.
 
166 6882 d 5 h decky /SPARTAN/trunk/arch/ppc/ prepare for PPC console support  
165 6882 d 6 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6882 d 6 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
163 6882 d 11 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6882 d 13 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script  
161 6884 d 13 h jermar /SPARTAN/trunk/arch/ For all relevant architectures, rename fake.s to dummy.s to better reflect the purpose of the file.
Also define global symbol called dummy.
 
160 6888 d 2 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.
 
159 6888 d 2 h jermar /SPARTAN/trunk/arch/ppc/include/ Fix copyright dates.  
157 6888 d 10 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
156 6888 d 13 h decky /SPARTAN/trunk/ PPC work in progress  
155 6890 d 3 h decky /SPARTAN/trunk/arch/powerpc/boot/ PPC preparation work (not working yet)  
154 6892 d 1 h jermar /SPARTAN/trunk/ Update TODO.
Explicitly mark places of interest related to memory barriers on non-IA-32 architectures with TODO remarks so that they don't get forgotten.
 
153 6892 d 2 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.
 
152 6904 d 4 h decky /SPARTAN/trunk/arch/ia64/ Cleanup  
151 6904 d 4 h decky /SPARTAN/trunk/arch/ia64/ Remove unnecessary IA64 unwind tables
Cleanup IA64 linker script
Thus IA64 port compiles again (and also works hopefully)
 
149 6904 d 5 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.
 
148 6909 d 9 h jermar /SPARTAN/trunk/arch/mips/ Add -mno-abicalls to prevent generating of PIC code.
Remove -mxgot option.
The MIPS port is functional again.
 
147 6909 d 10 h jermar /SPARTAN/trunk/arch/ Add missing memory_init.h files for IA-64 and MIPS architectures.
Fix typo in IA-32's memory_init.h.
 
146 6909 d 11 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
144 6909 d 11 h vana /SPARTAN/trunk/ Coding style fix  
143 6909 d 11 h vana /SPARTAN/trunk/ Disable alignment check

141 6909 d 12 h vana /SPARTAN/trunk/ Clear IOPL on start of system on all CPUs and clear NT before all irets.  
139 6910 d 8 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
137 6910 d 10 h vana /SPARTAN/trunk/arch/ia32/src/ Comments  
136 6910 d 10 h vana /SPARTAN/trunk/ Error word support debuging and testing passed with #NM & #GP exceptions.

134 6910 d 11 h decky /SPARTAN/trunk/arch/mips/include/mm/ Add missing asid.h  
132 6910 d 14 h vana /SPARTAN/trunk/arch/ia32/ Added support for error-word generating exceptions in return routine.  
131 6910 d 14 h jermar /SPARTAN/trunk/arch/ia32/src/ Initialize kmp_completion_wq during configuration via ACPI MADT.
