3591 5750 d 8 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 5755 d 12 h rimsky /branches/sparc/ Made changes making HelenOS run on US-IV CPUs. Minor refactoring of the SGCN driver.  
3549 5762 d 23 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 5773 d 0 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 5784 d 3 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3479 5799 d 8 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 5806 d 1 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 5816 d 8 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5816 d 8 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5834 d 0 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 5840 d 5 h decky /branches/sparc/ add sparc branch  
3324 5844 d 5 h jermar /trunk/boot/arch/sparc64/loader/ Boot support for FAT16 on sparc64.  
3274 5849 d 7 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 5850 d 4 h decky /trunk/boot/arch/ use less cryptic filenames  
3244 5854 d 0 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 5860 d 5 h jermar /trunk/boot/arch/sparc64/ Don't ask whether to replace image.boot.gz if it already exists.  
3237 5862 d 4 h jermar /trunk/boot/arch/sparc64/ Compress image.boot when creating a sparc64 bootable CD, making thus use
of SILO's decompressing ability.
 
3222 5882 d 6 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3146 5905 d 11 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 5906 d 1 h jermar /trunk/boot/arch/sparc64/loader/ Issue a sparc64 write barrier before passing control from the loader to
the kernel.
 
3052 5917 d 8 h decky /trunk/boot/arch/ RAM disk / filesystem support  
3027 5921 d 8 h decky /trunk/boot/ finish unifying pack script  
3024 5922 d 6 h decky /trunk/boot/arch/ use unified pack script by arm32  
2649 6086 d 15 h jermar /trunk/boot/arch/ Enable tmpfs in arm32, ia32xen, ia64, ppc32, ppc64 and sparc64.  
2551 6166 d 5 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2511 6185 d 2 h vana /trunk/ IA64 loader (based on sparc loader)  
2507 6217 d 7 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 6263 d 9 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6286 d 1 h decky /trunk/ update for new compiler configuration scheme  
2250 6332 d 1 h jermar /trunk/boot/ Fix ticket #31.  
2237 6336 d 1 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2185 6341 d 10 h decky /trunk/ rename ipcc to tester  
2160 6349 d 3 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6350 d 22 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 6415 d 9 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6420 d 2 h jermar /trunk/ (c) versus (C)  
1997 6474 d 3 h decky /trunk/ add version to init and boot loader  
1989 6477 d 7 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6480 d 9 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 6481 d 1 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.
