399 6843 d 2 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).
 
397 6843 d 15 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6844 d 12 h jermar /SPARTAN/trunk/ Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)

MIPS32 pte_t.c is not bool.
 
394 6845 d 4 h jermar /SPARTAN/trunk/arch/mips32/ MIPS32 memory management work.
Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14).
Introduce two new bits in pte_t (i.e. 'a' and 'w').
Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)
 
391 6846 d 3 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
389 6846 d 14 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
376 6855 d 8 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
368 6859 d 12 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
364 6860 d 15 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.
 
363 6861 d 4 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.

344 6868 d 5 h palkovsky /SPARTAN/trunk/ Added more code to arc.
Fixed bad name in byteorder.h
 
342 6868 d 11 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
341 6868 d 11 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
339 6869 d 9 h palkovsky /SPARTAN/trunk/arch/mips/ Make the objcopy files compatibile with gnu-sgi-irix linker.  
338 6869 d 10 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
334 6869 d 12 h jermar /SPARTAN/trunk/arch/ Cleanup.
Cancel __fake in pm.c and replace it with LONG(0xdeadbeaf) in linker script. Still need some to find out why it must be there.
Remove comment saying, that mips is little-endian.
 
332 6869 d 12 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 6870 d 7 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 6870 d 8 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
327 6871 d 0 h palkovsky /SPARTAN/trunk/ Doc updates, small fixes.

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.
 
325 6871 d 8 h palkovsky /SPARTAN/trunk/arch/mips/include/ Forgotten file...  
324 6871 d 11 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.
 
321 6872 d 4 h palkovsky /SPARTAN/trunk/arch/mips/boot/ Fixed bad instructions in loader.  
320 6872 d 4 h palkovsky /SPARTAN/trunk/arch/mips/src/ Bad stack settings. Why did not msim complain??  
319 6873 d 15 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6873 d 15 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
314 6874 d 2 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6874 d 2 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
309 6874 d 15 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
308 6874 d 16 h jermar /SPARTAN/trunk/arch/mips/src/ Just formatting changes.  
307 6874 d 16 h palkovsky /SPARTAN/trunk/ Fixed things broken by last commit.  
306 6874 d 16 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.
 
293 6876 d 2 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
292 6876 d 2 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().

the constants are all only in the header files.
 
268 6877 d 8 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
