1842 6532 d 23 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 6533 d 0 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 6533 d 12 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)
 
1838 6537 d 20 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6538 d 4 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 6540 d 0 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6540 d 11 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6540 d 12 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6540 d 12 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6540 d 13 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6540 d 15 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6540 d 15 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6540 d 17 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6540 d 17 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6540 d 19 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6540 d 20 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6541 d 1 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 6542 d 20 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6547 d 15 h decky /trunk/kernel/ make burst updates  
1817 6548 d 11 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 6548 d 20 h decky /trunk/kernel/ xen memory initialization  
1815 6548 d 22 h decky /trunk/kernel/arch/xen32/src/ fork drivers  
1814 6548 d 22 h decky /trunk/kernel/arch/xen32/include/ fork drivers  
1813 6548 d 22 h decky /trunk/kernel/arch/xen32/ xen32 hypervisor interface  
1812 6548 d 22 h decky /trunk/kernel/ move macro and cleanup  
1811 6549 d 0 h decky /trunk/kernel/arch/ unify bootstrapping  
1810 6555 d 13 h decky /trunk/kernel/arch/xen32/ remove obsolete stuff  
1809 6555 d 15 h decky /trunk/kernel/arch/xen32/ update xen32 support (most of the code is still dummy)  
1808 6555 d 15 h decky /trunk/kernel/arch/xen32/include/ fork directories

1805 6556 d 0 h decky /trunk/kernel/arch/xen32/src/boot/ make Xen recognize the kernel image  
1804 6556 d 0 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6556 d 11 h decky /trunk/ cleanup and unify the build system  
1793 6559 d 1 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 6559 d 14 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 6559 d 19 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 6559 d 21 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.
 
1787 6561 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6562 d 15 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
