1837 6505 d 4 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.

1831 6507 d 12 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console

1826 6507 d 18 h decky /trunk/kernel/generic/src/main/ some debugging output  
1825 6507 d 18 h decky /trunk/boot/arch/xen32/ optional xen binary with debugging enabled  
1824 6507 d 19 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6507 d 20 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6508 d 1 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.
