1852 6471 d 15 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 6476 d 20 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 6479 d 22 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1849 6480 d 22 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 6487 d 0 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 6488 d 15 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 6488 d 20 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 6488 d 21 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 6489 d 9 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1838 6493 d 17 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6494 d 1 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 6495 d 21 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6496 d 8 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6496 d 9 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6496 d 9 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6496 d 10 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6496 d 12 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6496 d 12 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6496 d 14 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6496 d 14 h decky /trunk/kernel/arch/xen32/src/ print memory map
