1841 6576 d 8 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 6576 d 20 h decky /trunk/kernel/arch/xen32/ claim copyright on files with significant xen32-related changes
(for the purpose of author's master thesis)
 
1838 6581 d 5 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6581 d 12 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 6583 d 8 h decky /trunk/kernel/arch/xen32/src/ coding style change  
1834 6583 d 20 h decky /trunk/kernel/arch/xen32/src/ xen32: fix initial stack  
1833 6583 d 20 h decky /trunk/kernel/ more sophisticated initial stack handling  
1832 6583 d 20 h decky /trunk/kernel/arch/xen32/ remap console page  
1831 6583 d 21 h decky /trunk/kernel/arch/xen32/ xen32: proper virtual traps, domU asynchronous console  
1830 6583 d 23 h decky /trunk/kernel/arch/xen32/ xen32: enable/disable interrupts  
1829 6584 d 0 h decky /trunk/kernel/arch/xen32/ xen32: initialize virtual IDT  
1828 6584 d 1 h decky /trunk/kernel/arch/xen32/ xen32: fork proc, get to the console (w/o preemption)  
1827 6584 d 1 h decky /trunk/kernel/arch/xen32/src/ print memory map  
1824 6584 d 3 h decky /trunk/kernel/arch/xen32/ xen32: use writable page tables, cleanup mm  
1823 6584 d 4 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6584 d 9 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 6586 d 4 h decky /trunk/kernel/arch/xen32/ xen32 cleanup  
1818 6591 d 0 h decky /trunk/kernel/ make burst updates  
1817 6591 d 20 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 6592 d 4 h decky /trunk/kernel/ xen memory initialization  
1815 6592 d 6 h decky /trunk/kernel/arch/xen32/src/ fork drivers  
1814 6592 d 6 h decky /trunk/kernel/arch/xen32/include/ fork drivers  
1813 6592 d 6 h decky /trunk/kernel/arch/xen32/ xen32 hypervisor interface  
1812 6592 d 6 h decky /trunk/kernel/ move macro and cleanup  
1811 6592 d 8 h decky /trunk/kernel/arch/ unify bootstrapping  
1810 6598 d 21 h decky /trunk/kernel/arch/xen32/ remove obsolete stuff  
1809 6598 d 23 h decky /trunk/kernel/arch/xen32/ update xen32 support (most of the code is still dummy)  
1808 6598 d 23 h decky /trunk/kernel/arch/xen32/include/ fork directories  
1807 6599 d 1 h decky /trunk/kernel/arch/xen32/ fork directories

1805 6599 d 8 h decky /trunk/kernel/arch/xen32/src/boot/ make Xen recognize the kernel image  
1804 6599 d 8 h decky /trunk/kernel/arch/xen32/ fork Xen32 makefile and linker script  
1802 6599 d 19 h decky /trunk/ cleanup and unify the build system  
1793 6602 d 9 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 6602 d 22 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 6603 d 3 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 6603 d 5 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 6605 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6605 d 23 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6612 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
