373 6813 d 15 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.		  
369 6815 d 16 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
298 6831 d 23 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
242 6834 d 21 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.		  
238 6835 d 17 h vana /SPARTAN/trunk/ Register dump on IA-64 exceptions  
235 6835 d 19 h decky /SPARTAN/trunk/ load the kernel above 1 MB on IA-32  
220 6836 d 3 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
212 6836 d 13 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6836 d 13 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
207 6837 d 0 h decky /SPARTAN/trunk/ separated stack mapping  
192 6837 d 18 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t.		  
184 6838 d 2 h jermar /SPARTAN/trunk/ Add lib/the.c.
Add and deploy the_initialize() and the_copy().

Make IA-32's before_thread_runs() use SP_DELTA macro.		  
180 6838 d 15 h jermar /SPARTAN/trunk/ Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.

Fix heap initialization to take 'heap_delta' into account.

Implement IA-64 get_stack_base().

Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).

More #include cleanup.		  
177 6838 d 23 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
174 6842 d 14 h jermar /SPARTAN/trunk/ Small changes.
Coding style fix in main.c.
Make 'cli' be the first instruction in boot.S again.		  
167 6848 d 22 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.		  
149 6872 d 15 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 6877 d 21 h cejka /SPARTAN/trunk/ Memory size detection for ia32 completed.  
108 6925 d 20 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
106 6925 d 22 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.
