1826 6523 d 11 h decky /trunk/kernel/generic/src/main/ some debugging output  
1824 6523 d 12 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6523 d 13 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6523 d 18 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 6539 d 4 h decky /trunk/ cleanup and unify the build system  
1794 6539 d 6 h decky /trunk/ move contrib from kernel/ to /
update Sparc64 toolchain to use Binutils 2.17 (neeeded for linking uspace)
 
1793 6541 d 18 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 6542 d 7 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 6542 d 12 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 6542 d 14 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 6544 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6545 d 8 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6551 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6551 d 14 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1776 6551 d 14 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1774 6551 d 21 h decky /kernel/trunk/ initial support for Xen  
1770 6552 d 14 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.  
1769 6554 d 8 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 6559 d 19 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
 
1766 6559 d 19 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1762 6561 d 5 h decky /kernel/trunk/arch/ppc32/src/cpu/ ppc32 identify known CPUs  
1761 6562 d 7 h jermar /kernel/trunk/doc/arch/ Upgrade amd64 hw compatibility list.
