1822 6591 d 5 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 6606 d 15 h decky /trunk/ cleanup and unify the build system  
1800 6606 d 16 h decky /trunk/boot/arch/ppc64/loader/ sync ppc64 with ppc32  
1799 6606 d 16 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1796 6606 d 16 h decky /trunk/boot/tools/ia64/ new place for vmaxlma  
1792 6609 d 18 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 6609 d 20 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 6609 d 23 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 6610 d 1 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 6611 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1786 6612 d 3 h jermar /boot/trunk/arch/sparc64/silo/ Upgrade to silo-1.4.11.  
1783 6612 d 19 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 6618 d 2 h jermar /boot/trunk/ Fix ofw.c to support map and translate methods even on 64-bit platforms.  
1779 6618 d 23 h jermar /boot/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1778 6619 d 1 h jermar /boot/trunk/arch/sparc64/ sparc64 is now booted by HelenOS boot loader.  
1775 6619 d 8 h decky /boot/trunk/ initial support for Xen  
1773 6619 d 17 h jermar /boot/trunk/arch/sparc64/loader/ Work on sparc64 boot loader (still inactive).  
1772 6619 d 18 h jermar /boot/trunk/genarch/ Last changes to make ofw.c work for both 32-bit and 64-bit architectures during boot.  
1771 6619 d 20 h jermar /boot/trunk/ Cleanup OpenFirmware driver and prepare it for integration with sparc64 bootloader.
Start sparc64 boot loader (now inactive and unfunctional).
 
1765 6627 d 18 h jermar /boot/trunk/arch/ppc64/loader/ Even though the ppc64 doesn't build currently, perform cleanup in the spirit of previous changes to mips32 and ppc32.  
1764 6627 d 19 h jermar /boot/trunk/ Cleanup boot infrastructure: ppc32 (and elsewhere).  
1763 6627 d 19 h jermar /boot/trunk/ Cleanup in the boot infrastructure.
This commit tries to separate generic stuff from mips32 specific stuff.
Other architectures will follow.
 
1755 6633 d 4 h decky /boot/trunk/arch/ppc32/loader/ read macio address from PCI OFW entry  
1748 6634 d 18 h decky /boot/trunk/arch/mips32/loader/ bugfix  
1747 6634 d 19 h decky /boot/trunk/ mips32 binary format choice  
1744 6634 d 19 h decky /boot/trunk/arch/mips32/loader/ use stack in unmapped segment  
1739 6635 d 3 h decky /boot/trunk/ ppc32 debug messages  
1738 6635 d 3 h decky /boot/trunk/arch/ppc32/loader/ properly place PHT on top of physical memory  
1737 6635 d 4 h decky /boot/trunk/arch/ppc32/loader/ pick the best BAT mapping  
1732 6635 d 15 h decky /boot/trunk/ fix wrong segment register value
add CONFIG_BAT define
 
1728 6635 d 16 h decky /boot/trunk/ ppc32: BAT usage is now optional
better VSID support
Page Hash Table cleanup
boot API change
 
1725 6635 d 23 h decky /boot/trunk/arch/ppc32/loader/ allocate page hash table during boot
(preliminary code, will be fixed properly later)
 
1715 6636 d 20 h decky /boot/trunk/arch/ppc32/loader/ move ppc32 four pages up  
1714 6636 d 20 h decky /boot/trunk/ change config
