3591 5717 d 20 h rimsky /branches/sparc/ Making the code compatible also with US-IV (US-IV+) - TLB size based on CPU autodetection, cleanup of code waking up APs. General cleanup.  
3582 5723 d 1 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5730 d 11 h rimsky /branches/sparc/ Implemented uspace Serengeti drivers for kbd and fb. Integrated with other parts of HelenOS. Now it is possible to play Tetris on a simulated Serengeti machine (usiii.simics).  
3502 5740 d 13 h rimsky /branches/sparc/ Implemented Serengeti console driver (only output, input TBD), all output now goes to the console instead of Simics CLI window.  
3492 5751 d 16 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3479 5766 d 21 h rimsky /branches/sparc/ Names containing 'UPA' replaced with strings containing more general 'ICBUS'. SMART_FIRMWARE option replaced with CPU autodetection + new option CONFIG_A_OUT_ISOFS_B.  
3467 5773 d 13 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 5783 d 21 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5783 d 21 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5801 d 13 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 5807 d 18 h decky /branches/sparc/ add sparc branch  
3324 5811 d 18 h jermar /trunk/boot/arch/sparc64/loader/ Boot support for FAT16 on sparc64.  
3274 5816 d 19 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 5817 d 17 h decky /trunk/boot/arch/ use less cryptic filenames  
3244 5821 d 13 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.
 
3222 5849 d 19 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3146 5873 d 0 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 5873 d 14 h jermar /trunk/boot/arch/sparc64/loader/ Issue a sparc64 write barrier before passing control from the loader to
the kernel.
 
3052 5884 d 20 h decky /trunk/boot/arch/ RAM disk / filesystem support  
3027 5888 d 20 h decky /trunk/boot/ finish unifying pack script  
3024 5889 d 19 h decky /trunk/boot/arch/ use unified pack script by arm32  
2649 6054 d 3 h jermar /trunk/boot/arch/ Enable tmpfs in arm32, ia32xen, ia64, ppc32, ppc64 and sparc64.  
2551 6133 d 17 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2511 6152 d 15 h vana /trunk/ IA64 loader (based on sparc loader)  
2507 6184 d 20 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 6230 d 21 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6253 d 14 h decky /trunk/ update for new compiler configuration scheme  
2250 6299 d 14 h jermar /trunk/boot/ Fix ticket #31.  
2185 6308 d 22 h decky /trunk/ rename ipcc to tester  
2160 6316 d 16 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6318 d 11 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 6382 d 22 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6387 d 14 h jermar /trunk/ (c) versus (C)  
1997 6441 d 15 h decky /trunk/ add version to init and boot loader  
1989 6444 d 20 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6447 d 22 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 6448 d 13 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.
 
1978 6448 d 14 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 6449 d 11 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 6460 d 21 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
