2442 6215 d 18 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2438 6215 d 18 h decky /trunk/ update for new compiler configuration scheme  
2302 6242 d 22 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2250 6261 d 19 h jermar /trunk/boot/ Fix ticket #31.  
2237 6265 d 18 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2185 6271 d 3 h decky /trunk/ rename ipcc to tester  
2160 6278 d 20 h decky /trunk/boot/arch/ remove duplicate dependency  
2141 6280 d 16 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.
 
2128 6323 d 20 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.
 
2082 6345 d 3 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6349 d 19 h jermar /trunk/ (c) versus (C)  
2048 6381 d 21 h jermar /trunk/ Formatting and indentation changes.  
2014 6390 d 21 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2013 6390 d 21 h decky /trunk/boot/arch/ bump to GRUB version 0.97  
1998 6403 d 20 h decky /trunk/boot/arch/ add version tag to other bootloaders  
1997 6403 d 20 h decky /trunk/ add version to init and boot loader  
1989 6407 d 1 h decky /trunk/boot/arch/sparc64/loader/ remove disasm on clean  
1982 6410 d 3 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 6410 d 18 h jermar /trunk/ Configuration changes on sparc64.
Compile TSB support by default.
Ask whether to start AP processors in the loader.
 
1978 6410 d 19 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 6411 d 16 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.
 
1973 6421 d 19 h jermar /trunk/boot/genarch/ Rewrite ofw_tree_node_process() to iterate through the peer list instead of recursing.  
1972 6423 d 2 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1952 6436 d 21 h jermar /trunk/ Rename xen32 to ia32xen.
The name seems to be more logical as Xen supports more host architectures.
 
1947 6437 d 20 h decky /trunk/boot/genarch/ add OFW quiesce command  
1917 6449 d 20 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.
 
1909 6456 d 19 h jermar /trunk/ Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.

Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet.
 
1907 6459 d 5 h jermar /trunk/ Add node handle to in-memory ofw tree node.
This is essential for interrupt mapping on sparc64
and perhaps on other platforms that have OpenFirmware.
 
1906 6459 d 22 h jermar /trunk/ Small improvements in sparc64.  
1903 6461 d 19 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 6463 d 3 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 6466 d 2 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6466 d 18 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.
 
1895 6468 d 19 h jermar /trunk/ More ofw_tree work and fixes.
Add ofw_tree_lookup().
Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups.
 
1894 6469 d 17 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 6469 d 21 h jermar /trunk/boot/ Add prototype implementation for creating canonical copy of OpenFirmware device tree.  
1881 6477 d 3 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 6485 d 16 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.
 
1837 6516 d 7 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1825 6518 d 22 h decky /trunk/boot/arch/xen32/ optional xen binary with debugging enabled
