1844 6508 d 14 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).		  
1843 6508 d 16 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6508 d 19 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 6508 d 20 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 6509 d 8 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1839 6512 d 16 h decky /trunk/kernel/generic/ finish security context isolation  
1838 6513 d 17 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6514 d 0 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 6515 d 20 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6516 d 8 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6516 d 8 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6516 d 8 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6516 d 9 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6516 d 11 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6516 d 12 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6516 d 13 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6516 d 13 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1826 6516 d 15 h decky /trunk/kernel/generic/src/main/ some debugging output  
1824 6516 d 15 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6516 d 17 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6516 d 21 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.
