1834 6537 d 15 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6537 d 15 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6537 d 16 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6537 d 16 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console

1826 6537 d 22 h decky /trunk/kernel/generic/src/main/ some debugging output  
1824 6537 d 22 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6538 d 0 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6538 d 4 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.

1817 6545 d 15 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner

1805 6553 d 3 h decky /trunk/kernel/arch/xen32/src/boot/ make Xen recognize the kernel image  
1804 6553 d 3 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6553 d 15 h decky /trunk/ cleanup and unify the build system  
1794 6553 d 16 h decky /trunk/ move contrib from kernel/ to /
update Sparc64 toolchain to use Binutils 2.17 (neeeded for linking uspace)
 
1793 6556 d 4 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 6556 d 17 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 6556 d 22 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 6557 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 6558 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6559 d 19 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6565 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6566 d 1 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.
