1841 6646 d 9 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 6646 d 21 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1839 6650 d 5 h decky /trunk/kernel/generic/ finish security context isolation  
1838 6651 d 5 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6651 d 13 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 6653 d 9 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1835 6653 d 10 h decky /trunk/ extraversion bump (and a test of new SVN repository)  
1834 6653 d 20 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6653 d 21 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6653 d 21 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6653 d 22 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6654 d 0 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6654 d 1 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6654 d 2 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6654 d 2 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1826 6654 d 3 h decky /trunk/kernel/generic/src/main/ some debugging output  
1825 6654 d 4 h decky /trunk/boot/arch/xen32/ optional xen binary with debugging enabled  
1824 6654 d 4 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6654 d 5 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6654 d 10 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.
