3582 5780 d 14 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5788 d 1 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 5798 d 2 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 5809 d 5 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3479 5824 d 10 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 5831 d 2 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 5841 d 10 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5841 d 10 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5859 d 2 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 5865 d 7 h decky /branches/sparc/ add sparc branch  
3324 5869 d 7 h jermar /trunk/boot/arch/sparc64/loader/ Boot support for FAT16 on sparc64.  
3323 5869 d 7 h jermar /trunk/boot/arch/ppc32/loader/ Boot support for FAT16 on ppc32. Currently breaks the system.  
3322 5869 d 7 h jermar /trunk/boot/arch/mips32/loader/ Boot support for FAT16 on mips32.
Not fully functional, but probably for another reason than on arm32.		  
3321 5869 d 8 h jermar /trunk/boot/arch/arm32/loader/ Boot support for FAT16 on arm32.  
3320 5869 d 8 h jermar /trunk/boot/arch/ia32/ Enable booting from FAT on ia32.  
3274 5874 d 9 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 5875 d 6 h decky /trunk/boot/arch/ use less cryptic filenames  
3244 5879 d 2 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.		  
3243 5880 d 3 h jermar /trunk/ Boot infrastructure support for FAT16 init ramdisks.
Only amd64 so far.		  
3239 5885 d 7 h jermar /trunk/boot/arch/sparc64/ Don't ask whether to replace image.boot.gz if it already exists.
