1852 6484 d 12 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 6489 d 17 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 6492 d 20 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1849 6493 d 19 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 6499 d 21 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 6501 d 12 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 6501 d 14 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6501 d 17 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 6501 d 18 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 6502 d 6 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)		  
1839 6505 d 14 h decky /trunk/kernel/generic/ finish security context isolation  
1838 6506 d 14 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6506 d 22 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 6508 d 18 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6509 d 5 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6509 d 6 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6509 d 6 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6509 d 7 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6509 d 9 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6509 d 10 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT
