3467 5763 d 15 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3398 5773 d 22 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5773 d 22 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5791 d 14 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5797 d 19 h decky /branches/sparc/ add sparc branch  
3324 5801 d 19 h jermar /trunk/boot/arch/sparc64/loader/ Boot support for FAT16 on sparc64.  
3274 5806 d 21 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3258 5807 d 18 h decky /trunk/boot/arch/ use less cryptic filenames  
3244 5811 d 14 h jermar /trunk/ Split mktmpfs.py to a TMPFS specific part and a HORD specific part. The latter
is moved to mkhord.py and can be reused for FAT16 images as well. mktmpfs.py and
mkfat.sh define the same interface now. Modify makefiles to use the modified
interface (e.g. do not pass alignment to either mktmpfs.py or mkfat.sh). FAT16
initrd image can be now loaded as initrd on amd64 and gets recognized as a
ramdisk image.
 
3239 5817 d 19 h jermar /trunk/boot/arch/sparc64/ Don't ask whether to replace image.boot.gz if it already exists.  
3237 5819 d 18 h jermar /trunk/boot/arch/sparc64/ Compress image.boot when creating a sparc64 bootable CD, making thus use
of SILO's decompressing ability.
 
3222 5839 d 20 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3146 5863 d 1 h jermar /trunk/boot/arch/sparc64/loader/ Don't make any assumptions about the contents of the I-cache in sparc64
loader and before passing control to the kernel, invalidate the I-cache.
 
3144 5863 d 15 h jermar /trunk/boot/arch/sparc64/loader/ Issue a sparc64 write barrier before passing control from the loader to
the kernel.
 
3052 5874 d 21 h decky /trunk/boot/arch/ RAM disk / filesystem support  
3027 5878 d 22 h decky /trunk/boot/ finish unifying pack script  
3024 5879 d 20 h decky /trunk/boot/arch/ use unified pack script by arm32  
2649 6044 d 5 h jermar /trunk/boot/arch/ Enable tmpfs in arm32, ia32xen, ia64, ppc32, ppc64 and sparc64.  
2551 6123 d 19 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2511 6142 d 16 h vana /trunk/ IA64 loader (based on sparc loader)  
2507 6174 d 21 h jermar /trunk/boot/arch/sparc64/loader/ Fix sparc64 loader's pack script for use with gcc 4.2.1 by
avoiding pointer to int type casts so that the newer gcc doesn't emit a warning.
Due to the -Werror flags, such a warning would prevent a successful build.
 
2479 6220 d 23 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6243 d 15 h decky /trunk/ update for new compiler configuration scheme  
2250 6289 d 15 h jermar /trunk/boot/ Fix ticket #31.  
2237 6293 d 15 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2185 6299 d 0 h decky /trunk/ rename ipcc to tester  
2160 6306 d 17 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6308 d 12 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2082 6372 d 23 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6377 d 16 h jermar /trunk/ (c) versus (C)  
1997 6431 d 17 h decky /trunk/ add version to init and boot loader  
1989 6434 d 21 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6437 d 23 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
 
1979 6438 d 15 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.
 
1978 6438 d 16 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
 
1977 6439 d 12 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.
 
1972 6450 d 22 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1917 6477 d 17 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.
 
1906 6487 d 18 h jermar /trunk/ Small improvements in sparc64.  
1903 6489 d 16 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.
