1834 6504 d 3 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6504 d 3 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6504 d 4 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6504 d 5 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console

1829 6504 d 7 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6504 d 9 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6504 d 9 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6504 d 11 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6504 d 12 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6504 d 17 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.
 
1821 6506 d 12 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6511 d 7 h decky /trunk/kernel/ make burst updates  
1817 6512 d 3 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner

1804 6519 d 16 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6520 d 3 h decky /trunk/ cleanup and unify the build system  
1793 6522 d 16 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1792 6523 d 6 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.
 
1790 6523 d 11 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 6523 d 13 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 6525 d 10 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6526 d 7 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6532 d 11 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6532 d 13 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1776 6532 d 13 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1774 6532 d 20 h decky /kernel/trunk/ initial support for Xen  
1770 6533 d 12 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.
