4153 6120 d 2 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 6316 d 5 h decky /branches/network/ add new network branch (copy of current trunk)  
3071 6408 d 6 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2089 6900 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6906 d 8 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6911 d 1 h jermar /trunk/ (c) versus (C)  
2068 6918 d 8 h jermar /trunk/kernel/ Formatting and indentation fixes.  
1911 7013 d 23 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
 
1899 7024 d 8 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree
 
1885 7036 d 12 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, get_stack_base() must use the unbiased %sp (i.e. %sp + 2047).  
1882 7037 d 8 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 7038 d 8 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.
 
1880 7040 d 0 h jermar /trunk/ Small improvements here and there.  
1865 7046 d 2 h jermar /trunk/kernel/ sparc64 kernel fixes  
1864 7046 d 22 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.
 
1860 7050 d 2 h jermar /trunk/kernel/ A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes.
 
1856 7051 d 10 h jermar /trunk/kernel/ sparc64 work.
- Modify before_thread_runs_arch() to store addresses of the kernel stack and
userspace window buffer, resp., to registers %g6 and %g7, resp, in the
alternate and interrupt global sets.
- Modify after_thread_ran_arch() to sample %g7 from the alternate globals.
- Implement trap handler for spilling register windows into userspace window buffer.
- Implement assembly language functions to access %g6 and %g7 registers in the alternate sets.
- Initialize the trap table so that there are now also spill_1_normal, spill_2_normal,
spill_0_other and fill_1_normal handlers. These handlers are used in different situations
and for different purposes.
 
1855 7052 d 6 h jermar /trunk/kernel/ sparc64 work.

Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.

Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer.
 
1849 7064 d 10 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.

1784 7102 d 0 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 7108 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 7126 d 10 h jermar /kernel/trunk/ Fix some broken doxygen comments.

No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.
