1967 6387 d 9 h jermar /tags/0.2.0.3/ Tagging release 0.2.0.3  
1825 6474 d 13 h decky /trunk/boot/arch/xen32/ optional xen binary with debugging enabled  
1822 6474 d 19 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.		  
1802 6490 d 6 h decky /trunk/ cleanup and unify the build system  
1800 6490 d 6 h decky /trunk/boot/arch/ppc64/loader/ sync ppc64 with ppc32  
1799 6490 d 7 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1796 6490 d 7 h decky /trunk/boot/tools/ia64/ new place for vmaxlma  
1792 6493 d 9 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.		  
1791 6493 d 11 h jermar /trunk/boot/arch/sparc64/loader/ Switch to identically mapped stack during boot.
Put stack related and register related macros to dedicated
header files.		  
1790 6493 d 13 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1789 6493 d 16 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.		  
1787 6495 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1786 6495 d 18 h jermar /boot/trunk/arch/sparc64/silo/ Upgrade to silo-1.4.11.  
1783 6496 d 10 h jermar /boot/trunk/ Some 32-bit vs. 64-bit fixes.

Make the call to OpenFirmware client interface architecture dependent.
For instance and contrary to my previous experience, the sparc64 version of
'translate' method would not work reliably unless the Address Mask bit in the
PSTATE register is cleared during duration of the call.

sparc64 and ppc32 OpenFirmware seem to differ in details, for example, the above
mentioned method 'translate' signals success by setting the first return value
to -1 on sparc64 while on ppc32 the value is/stays (???) zero.		  
1782 6501 d 17 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1779 6502 d 14 h jermar /boot/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1778 6502 d 16 h jermar /boot/trunk/arch/sparc64/ sparc64 is now booted by HelenOS boot loader.  
1775 6502 d 23 h decky /boot/trunk/ initial support for Xen  
1773 6503 d 8 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1772 6503 d 8 h jermar /boot/trunk/genarch/ Last changes to make ofw.c work for both 32-bit and 64-bit architectures during boot.
