1852 6516 d 23 h jermar /trunk/kernel/ sparc64 work.
Bunch of changes in preparation for sparc64 mm and userspace support.
Fix alignment of hardcoded_* variables in linker script.		  
1851 6522 d 4 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1850 6525 d 7 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1849 6526 d 6 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled.		  
1848 6532 d 8 h jermar /trunk/kernel/ Rework the z8530 driver so that it is based on z8530 specification rather
than on accidental and limited "compatibility" with i8042.		  
1844 6533 d 23 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 6534 d 1 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6534 d 4 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 6534 d 5 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 6534 d 17 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1839 6538 d 1 h decky /trunk/kernel/generic/ finish security context isolation  
1838 6539 d 1 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6539 d 9 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 6541 d 5 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6541 d 17 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6541 d 17 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6541 d 17 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6541 d 18 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6541 d 20 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6541 d 21 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6541 d 22 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6541 d 22 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1826 6541 d 23 h decky /trunk/kernel/generic/src/main/ some debugging output  
1824 6542 d 0 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6542 d 1 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6542 d 6 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 6544 d 1 h decky /trunk/kernel/arch/xen32/ xen32 cleanup

1817 6549 d 17 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
