3153 5819 d 21 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3149 5819 d 22 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3107 5830 d 2 h svoboda /branches/dynload/ Merge trunk changes up to r3044 into dynload  
2927 5852 d 1 h decky /branches/dynload/ added dynload branch  
2649 6002 d 3 h jermar /trunk/boot/arch/ Enable tmpfs in arm32, ia32xen, ia64, ppc32, ppc64 and sparc64.  
2551 6081 d 17 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2511 6100 d 15 h vana /trunk/ IA64 loader (based on sparc loader)  
2507 6132 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 6178 d 21 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2438 6201 d 13 h decky /trunk/ update for new compiler configuration scheme  
2250 6247 d 14 h jermar /trunk/boot/ Fix ticket #31.  
2237 6251 d 13 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2185 6256 d 22 h decky /trunk/ rename ipcc to tester  
2160 6264 d 15 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6266 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 6330 d 22 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6335 d 14 h jermar /trunk/ (c) versus (C)  
1997 6389 d 15 h decky /trunk/ add version to init and boot loader  
1989 6392 d 20 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6395 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 6396 d 13 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.
 
1978 6396 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 6397 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 6408 d 21 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1917 6435 d 15 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 6445 d 17 h jermar /trunk/ Small improvements in sparc64.  
1903 6447 d 15 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.
 
1899 6448 d 22 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree
 
1897 6451 d 21 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6452 d 13 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
 
1894 6455 d 12 h jermar /trunk/ Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations

More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree

sparc64 boot:
- pass OFW device tree root node pointer to kernel
 
1893 6455 d 16 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6462 d 22 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.
 
1864 6471 d 11 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.
