4220 5562 d 8 h decky /trunk/kernel/ update for string changes  
4119 5583 d 7 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4111 5583 d 20 h jermar /trunk/kernel/arch/sparc64/ Update the SGCN driver to match the latest character I/O changes.  
4072 5584 d 20 h jermar /trunk/kernel/arch/sparc64/src/ Fix sparc64 builds without srln.  
4071 5584 d 20 h jermar /trunk/kernel/arch/sparc64/ Some additional fixes to the sgcn driver.  
4070 5584 d 22 h rimsky /trunk/ SGCN driver modified to reflect the new keyboard driver architecture. Making the Serengeti bootable image smaller by not including some servers/applications.  
4042 5589 d 0 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.
 
4011 5593 d 18 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3961 5602 d 0 h jermar /trunk/ Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace.
 
3900 5609 d 2 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3865 5615 d 17 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3790 5647 d 4 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3740 5660 d 23 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5662 d 2 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3672 5680 d 20 h jermar /trunk/ Merge sparc branch to trunk.  
3646 5687 d 20 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
2089 6358 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6368 d 19 h jermar /trunk/ (c) versus (C)  
1931 6460 d 20 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1897 6485 d 3 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6485 d 18 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.
 
1888 6493 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1880 6497 d 18 h jermar /trunk/ Small improvements here and there.  
1875 6500 d 20 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
 
1849 6522 d 4 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.
 
1844 6529 d 21 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 6530 d 2 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 6530 d 3 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.
 
1837 6535 d 7 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.
 
1822 6538 d 4 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.
 
1790 6556 d 22 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.
 
1787 6558 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6559 d 19 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1769 6568 d 18 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1702 6587 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1410 6607 d 2 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.
 
1382 6610 d 19 h decky /kernel/trunk/ make hardware memory mapping more generic  
1376 6612 d 3 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.  
1135 6666 d 17 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader
 
897 6692 d 16 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.
