1844 6496 d 17 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).		  
1842 6496 d 22 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.		  
1841 6496 d 23 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 6497 d 11 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1838 6501 d 19 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6502 d 3 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 6503 d 23 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6504 d 10 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6504 d 11 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6504 d 11 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6504 d 12 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6504 d 14 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6504 d 15 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6504 d 16 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6504 d 16 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6504 d 18 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6504 d 19 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6505 d 0 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 6506 d 19 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6511 d 14 h decky /trunk/kernel/ make burst updates
