1838 6613 d 21 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6614 d 5 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 6616 d 1 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6616 d 12 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6616 d 12 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6616 d 13 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6616 d 13 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6616 d 16 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6616 d 16 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6616 d 18 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6616 d 18 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6616 d 20 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6616 d 21 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6617 d 2 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 6618 d 21 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6623 d 16 h decky /trunk/kernel/ make burst updates  
1817 6624 d 12 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 6624 d 21 h decky /trunk/kernel/ xen memory initialization  
1815 6624 d 22 h decky /trunk/kernel/arch/xen32/src/ fork drivers
