1840 6614 d 9 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1838 6618 d 17 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6619 d 1 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 6620 d 21 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6621 d 8 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6621 d 8 h decky /trunk/kernel/ more sophisticated initial stack handling

1831 6621 d 9 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console

1828 6621 d 14 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6621 d 14 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6621 d 16 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6621 d 17 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6621 d 22 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 6623 d 17 h decky /trunk/kernel/arch/xen32/ xen32 cleanup

1817 6629 d 8 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
