389 6855 d 3 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().

332 6878 d 1 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
 
330 6878 d 20 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad address loading in simulators.
FPU cooprocessor unusable now checks, if it is FPU that is unusable.
 
329 6878 d 20 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
327 6879 d 13 h palkovsky /SPARTAN/trunk/ Doc updates, small fixes.  
326 6879 d 13 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
324 6880 d 0 h palkovsky /SPARTAN/trunk/ MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet.
 
320 6880 d 17 h palkovsky /SPARTAN/trunk/arch/mips/src/ Bad stack settings. Why did not msim complain??  
319 6882 d 4 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6882 d 4 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
314 6882 d 15 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6882 d 15 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
309 6883 d 4 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
308 6883 d 4 h jermar /SPARTAN/trunk/arch/mips/src/ Just formatting changes.  
306 6883 d 5 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.
 
268 6885 d 21 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
266 6886 d 0 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
240 6887 d 19 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad register assignment in atomic.h.
Added -msoft-float so that it does not call coprocessor and it works withou doubles.
Removed undefined symbol from tlb.c. Unfortunately
mips linker does not report missing symbols.
 
237 6887 d 20 h palkovsky /SPARTAN/trunk/arch/mips/src/ Fixed missing semicolon;  
230 6887 d 23 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
227 6887 d 23 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.
 
213 6888 d 16 h jermar /SPARTAN/trunk/ Add some comments.  
212 6888 d 16 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
205 6889 d 4 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
 
195 6889 d 18 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
 
161 6905 d 2 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.
 
130 6931 d 3 h decky /SPARTAN/trunk/arch/mips/ Make MIPS target compile and link properly with the new 4.0.1 MIPS toolchain  
127 6933 d 3 h jermar /SPARTAN/trunk/arch/ Copyright owner of arch/mips/src/mm/asid.c is Martin Decky.

ACPI code now understands L_APIC and IO_APIC entries in MADT.
 
126 6933 d 5 h decky /SPARTAN/trunk/arch/mips/src/mm/ Start ASID manipulation  
125 6935 d 16 h jermar /SPARTAN/trunk/ Huge indentation fix.  
124 6935 d 18 h decky /SPARTAN/trunk/arch/mips/ fix EXC_Mod define

enhance interrupt handling
 
123 6935 d 18 h decky /SPARTAN/trunk/arch/mips/ handle more MIPS exceptions  
121 6936 d 16 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 6950 d 15 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.
 
113 6974 d 13 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.
