171 6837 d 19 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.		  
170 6840 d 9 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 6841 d 9 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
168 6841 d 10 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 6842 d 18 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 6844 d 12 h decky /SPARTAN/trunk/arch/ppc/ prepare for PPC console support  
165 6844 d 12 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6844 d 12 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
163 6844 d 18 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6844 d 19 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script  
161 6846 d 20 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 6850 d 8 h jermar /SPARTAN/trunk/ PPC work.
Define dummy implementations of many functions in fake.s.
Define kernel_image_start in start.S.		  
159 6850 d 9 h jermar /SPARTAN/trunk/arch/ppc/include/ Fix copyright dates.  
158 6850 d 17 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment

156 6850 d 20 h decky /SPARTAN/trunk/ PPC work in progress  
155 6852 d 9 h decky /SPARTAN/trunk/arch/powerpc/boot/ PPC preparation work (not working yet)  
154 6854 d 8 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 6854 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.
