1848 6571 d 9 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 6573 d 0 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 6573 d 5 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 6573 d 6 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 6573 d 18 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)
 
1838 6578 d 3 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6578 d 10 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 6580 d 6 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6580 d 18 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6580 d 18 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6580 d 18 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6580 d 19 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6580 d 21 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6580 d 22 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6580 d 23 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6580 d 23 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6581 d 1 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6581 d 2 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6581 d 7 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 6583 d 3 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6587 d 22 h decky /trunk/kernel/ make burst updates  
1817 6588 d 18 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
 
1816 6589 d 2 h decky /trunk/kernel/ xen memory initialization  
1815 6589 d 4 h decky /trunk/kernel/arch/xen32/src/ fork drivers  
1814 6589 d 4 h decky /trunk/kernel/arch/xen32/include/ fork drivers  
1813 6589 d 4 h decky /trunk/kernel/arch/xen32/ xen32 hypervisor interface  
1812 6589 d 4 h decky /trunk/kernel/ move macro and cleanup  
1811 6589 d 6 h decky /trunk/kernel/arch/ unify bootstrapping  
1810 6595 d 19 h decky /trunk/kernel/arch/xen32/ remove obsolete stuff  
1809 6595 d 21 h decky /trunk/kernel/arch/xen32/ update xen32 support (most of the code is still dummy)  
1808 6595 d 22 h decky /trunk/kernel/arch/xen32/include/ fork directories  
1807 6595 d 23 h decky /trunk/kernel/arch/xen32/ fork directories  
1806 6595 d 23 h decky /trunk/kernel/arch/xen32/ fork directories  
1805 6596 d 6 h decky /trunk/kernel/arch/xen32/src/boot/ make Xen recognize the kernel image  
1804 6596 d 6 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6596 d 18 h decky /trunk/ cleanup and unify the build system  
1793 6599 d 7 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1792 6599 d 20 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.
 
1790 6600 d 1 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1789 6600 d 3 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.
