1824 6629 d 17 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6629 d 19 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6629 d 23 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 6631 d 19 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6636 d 14 h decky /trunk/kernel/ make burst updates  
1817 6637 d 10 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
 
1816 6637 d 19 h decky /trunk/kernel/ xen memory initialization  
1815 6637 d 20 h decky /trunk/kernel/arch/xen32/src/ fork drivers  
1814 6637 d 20 h decky /trunk/kernel/arch/xen32/include/ fork drivers

1809 6644 d 13 h decky /trunk/kernel/arch/xen32/ update xen32 support (most of the code is still dummy)

1804 6644 d 22 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6645 d 10 h decky /trunk/ cleanup and unify the build system  
1793 6647 d 23 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 6648 d 12 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 6648 d 17 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 6648 d 20 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 6650 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6651 d 14 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6657 d 17 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6657 d 20 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1776 6657 d 20 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1774 6658 d 3 h decky /kernel/trunk/ initial support for Xen  
1770 6658 d 19 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.  
1769 6660 d 13 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1767 6666 d 0 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
