1841 6522 d 5 h jermar /trunk/kernel/ Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.

The repository won't compile now. To be fixed in next commits.
 
1840 6522 d 17 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)
 
1839 6526 d 1 h decky /trunk/kernel/generic/ finish security context isolation  
1838 6527 d 1 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6527 d 9 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1836 6529 d 5 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6529 d 16 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6529 d 16 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6529 d 17 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6529 d 17 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6529 d 20 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6529 d 20 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6529 d 22 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6529 d 22 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1826 6529 d 23 h decky /trunk/kernel/generic/src/main/ some debugging output  
1824 6530 d 0 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6530 d 1 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6530 d 6 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 6532 d 1 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1820 6533 d 18 h decky /trunk/kernel/generic/ initial security context support  
1819 6533 d 18 h decky /trunk/kernel/generic/include/ formatting changes  
1818 6536 d 20 h decky /trunk/kernel/ make burst updates  
1817 6537 d 16 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 6538 d 1 h decky /trunk/kernel/ xen memory initialization  
1815 6538 d 2 h decky /trunk/kernel/arch/xen32/src/ fork drivers  
1814 6538 d 2 h decky /trunk/kernel/arch/xen32/include/ fork drivers  
1813 6538 d 3 h decky /trunk/kernel/arch/xen32/ xen32 hypervisor interface  
1812 6538 d 3 h decky /trunk/kernel/ move macro and cleanup  
1811 6538 d 5 h decky /trunk/kernel/arch/ unify bootstrapping  
1810 6544 d 18 h decky /trunk/kernel/arch/xen32/ remove obsolete stuff  
1809 6544 d 20 h decky /trunk/kernel/arch/xen32/ update xen32 support (most of the code is still dummy)  
1808 6544 d 20 h decky /trunk/kernel/arch/xen32/include/ fork directories

1805 6545 d 4 h decky /trunk/kernel/arch/xen32/src/boot/ make Xen recognize the kernel image  
1804 6545 d 5 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6545 d 16 h decky /trunk/ cleanup and unify the build system  
1794 6545 d 17 h decky /trunk/ move contrib from kernel/ to /
update Sparc64 toolchain to use Binutils 2.17 (neeeded for linking uspace)
 
1793 6548 d 5 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 6548 d 19 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.
